Description

Technical Field

[0001] This invention relates to the field of microcrystalline cast stone production equipment, specifically a feeding machine for a microcrystalline cast stone production kiln. Background Technology

[0002] Microcrystalline stone needs to be processed in a kiln during the production process. During the processing of microcrystalline stone, it is also necessary to use a feeding device to feed materials into the kiln. However, the feeding flow of traditional feeding devices is difficult to control, and the material will remain on the inner wall of the device during feeding, which will greatly reduce the accuracy of feeding.

[0003] Chinese patent application CN115676434A discloses a feeding mechanism for a furnace used in the production of carrier glass. This patent describes a method where, when the material for producing carrier glass is poured onto the top of a dropping plate, a baffle blocks the material. The dropping plate has a very small inclination, and under the vibration of a vibrating motor, the material passes through the gap between the baffle and the dropping plate, entering the feed hopper from the dropping plate. Because the material slowly falls from the top of the dropping plate into the feed hopper, it prevents material from entering the conveying pipe and causing blockages, thus facilitating feeding. However, this patent, by using vibration to feed the material into the furnace, cannot precisely control the addition of material. Therefore, this invention provides a feeding machine for a microcrystalline cast stone production furnace to solve the aforementioned problems. Summary of the Invention

[0009] The inner wall of the feeding cylinder is provided with several mounting grooves, and each mounting groove is fixedly connected with a flexible block for cleaning the inner wall of the feeding cylinder. The inner wall of the mounting groove is provided with an air inlet.

[0010] As a further embodiment of the present invention, the power structure includes a power box, a power motor is installed inside the power box, a power shaft is connected to the output shaft of the power motor via a coupling, a pendulum is fixedly connected to the end of the power shaft away from the power motor, a pendulum rod is movably connected to the end of the pendulum away from the power motor, the pendulum rod passes through the feed cylinder and is rotatably connected to the piston disc, and an adjustment structure for adjusting the height of the pendulum rod is installed inside the pendulum.

[0011] As a further embodiment of the present invention, the adjustment structure includes an electromagnet block, which is slidably connected to a pendulum. A sliding groove is provided at the end of the pendulum away from the power motor, and a threaded rod is rotatably connected inside the sliding groove. The electromagnet block is threadedly connected to the threaded rod.

[0012] As a further embodiment of the present invention, the pendulum has two drive gears internally rotatably connected, one of which is fixedly connected to a threaded rod, and the upper end of the other drive gear is fixedly connected to an adjusting motor.

[0013] As a further embodiment of the present invention, a slider is slidably connected inside the swing arm, a connecting shaft is rotatably connected inside the slider, the connecting shaft is fixedly connected to the electromagnet block, and an adsorption block is sleeved on the outside of the connecting shaft. An iron disk is rotatably connected to one end of the adsorption block near the electromagnet block. The adsorption block is slidably connected to the slider through an optical axis, and a return spring is also sleeved on the outside of the optical axis.

The fixing block is fixedly connected to the feeding pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. When this invention is used, the pendulum will drive the pendulum rod to slide up and down during the rotation process. When the pendulum rod slides upward, it will push the piston plate to move upward. During the upward sliding of the piston plate, it will push the blocking head inside the discharge pipe through the push rod. At this time, the material in the receiving hopper will flow into the inside of the discharge cylinder through the discharge pipe. When the piston plate moves downward and contacts the pressure sensor, the distributing motor will drive the distributing plate to rotate, so that the material is thrown into the feeding pipe under the action of centrifugal force, thereby completing the material conveying and allowing the material to enter the kiln.

[0019] 2. When the present invention is used, a pressure difference will be generated between the inside and outside of the feed cylinder as the piston disc moves downward with the swing rod. At this time, the flexible block will expand. When the flexible block expands, the material remaining on the surface of the flexible block will fall off the flexible block. In this way, material is avoided from remaining on the inner wall of the feed cylinder, thereby avoiding affecting the accuracy of feeding.

[0020] 3. In specific use, the material in the receiving hopper can be transferred to the distributing plate in two ways. One is to control the pendulum to rotate slowly and continuously with a motor. In this case, only a small amount of material will enter the feeding cylinder each time, which is suitable for situations where a small amount of material needs to be added. The other is to control the rotation angle of the pendulum. When the pendulum rod drives the piston plate to the highest point, the pendulum is controlled to stop rotating. After a specified time, the pendulum rod is allowed to rotate again to drive the piston plate to reset. This method allows more material to enter the feeding cylinder. This method is suitable for situations where a large amount of material needs to be added at once. This method increases the versatility and applicability of the invention.

[0040] The working principle of this invention is:

[0041] When this invention is in use, the power motor is turned on to drive the pendulum 301 to rotate. During the rotation of the pendulum 301, the pendulum 301 will drive the pendulum rod 304 to slide up and down. When the pendulum rod 304 slides upward, it will push the piston disc 207 to move upward. During the upward sliding of the piston disc 207, it will push the blocking head 203 inside the discharge pipe 202 through the pushing rod 209. When the blocking head 203 is pushed into the inside of the receiving hopper 201, the discharge pipe 202 will lose the obstruction of the blocking head 203. At this time, the material in the receiving hopper 201 will flow into the discharge pipe 202 through the space between the receiving hopper 201 and the blocking head 203, and then flow into the inside of the discharge cylinder 2 from the discharge pipe 202.

[0042] When the swing arm 304 moves downward, it will drive the material to move downward together. When the piston disc 207 contacts the pressure sensor 211, the material distribution motor 210 will drive the material distribution disc 208 to rotate, so that the material is thrown to the outside of the material cylinder 2 under the action of centrifugal force. During the process of being thrown, some of the material will enter the feeding pipe 400. As the material distribution disc 208 continues to rotate, more material will be sent into the feeding pipe 400, thereby completing the material conveying and allowing the material to enter the kiln.

[0043] As the piston disc 207 moves downward following the rocker arm 304, a pressure difference is generated between the inside and outside of the feed cylinder 2. At this time, the flexible block 215 will expand. When the flexible block 215 expands, the material remaining on the surface of the flexible block 215 will fall off the flexible block 215. In this way, material is avoided from remaining on the inner wall of the feed cylinder 2 (there are several flexible blocks 215 on the inner wall of the feed cylinder 2, which means that the inner wall of the feed cylinder 2 is almost replaced by the flexible blocks 215. When the flexible blocks 215 expand, the surface will expand, causing the material to fall off), thereby avoiding affecting the accuracy of feeding.

[0044] By turning off the electromagnet block 308 to separate it from the adsorption block 310, and then turning on the adjusting motor 312 to drive the threaded rod 307 to rotate, the electromagnet block 308 moves upward (to... Figure 6 (For reference), after the electromagnet block 308 moves to the designated position, it is activated again to re-attract the adsorption block 310. Once the electromagnet block 308 has attracted the adsorption block 310, its magnetic force is transmitted to the slider 309, causing it to adhere to the swing arm 304, thus fixing the slider 309 and the swing arm 304 (the slider 309, swing arm 304, optical axis 311, and adsorption block 310 are all made of iron, and magnetism can be conducted between iron materials). At this point, when the power motor is activated again to rotate the pendulum 301, the swing arm 304 drives the piston disc 207 to move upwards. The distance will be shortened. The shorter upward movement of the piston disc 207 will cause the push rod 209 to push the blocking head 203 upward by a shorter distance. This makes the blocking head 203 closer to the discharge pipe 202 when it is pushed into the receiving hopper 201, thus reducing the space that the material can pass through in the receiving hopper 201 and controlling the flow rate of the material (the receiving hopper 201 is funnel-shaped, so the inner diameter of the receiving hopper 201 gradually increases from bottom to top, while the maximum outer diameter of the blocking head 203 is fixed. Therefore, the farther the blocking head 203 is from the bottom of the receiving hopper 201, the larger the space that the material can pass through, and vice versa).

[0045] When the pendulum 301 rotates, the lever 505 is blocked by the push rod 501. At this time, the lever 505 will drive the traction block 5 to move together through the push rod 501. During the movement, the traction block 5 will pull the spring plate 401 through the traction rope 6. During the movement, the limit block 504 will be blocked by the limit protrusion 10. When the limit block 504 is blocked, the blocking block 500 will no longer move with the traction block 5. At this time, the push rod 501 will slide from the blocking platform 502 into the docking groove 503. At this time, the lever 505 will push the push rod 501 into the docking groove 503, thereby separating the push rod 501 from the lever 505. After the push rod 501 and the lever 505 are separated, the traction block 5 will reset. At this time, the spring plate 401 will hit the outer wall of the feeding pipe 400, thereby causing the feeding pipe 400 to vibrate, thus preventing material residue on the outer wall of the feeding pipe 400.

[0046] Specifically, there are two ways to transfer the material in the receiving hopper 201 to the distributing plate 208. One way is to control the pendulum 301 to rotate slowly and continuously with the power motor. In this case, only a small amount of material will enter the feeding cylinder 2 each time, which is suitable for situations where a small amount of material needs to be added. The other way is to control the rotation angle of the pendulum 301. When the pendulum rod 304 drives the piston plate 207 to the highest point, the pendulum 301 is controlled to stop rotating. After a specified time, the pendulum 301 drives the pendulum rod 304 to rotate, which drives the piston plate 207 to reset. In this way, more material can enter the feeding cylinder 2. This method is suitable for situations where a large amount of material needs to be added at once. This method increases the versatility and applicability of the invention.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
