DETAILED DESCRIPTION

[0038] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0039] The present invention discloses a sintering device for producing ceramic capacitors, such as Figure 1-13As shown, it includes a sintering cylinder 100, a transmission assembly shaft 300, an air-cooled cooling mechanism 400, and multiple hanging basket-type loading mechanisms 200, wherein a support base 112 is installed at the lower end of the sintering cylinder 100, and the support base 112 is fixed to the ground and is used to support the sintering cylinder 100. The multiple hanging basket-type loading mechanisms 200 of the present invention are arranged in the sintering cylinder 100 at intervals along the axial direction of the sintering cylinder 100. The two ends of the transmission assembly shaft 300 extend out of the sintering cylinder 100 along the axis of the sintering cylinder 100, and the two ends of the transmission assembly shaft 300 are respectively rotatably connected to the corresponding positions of the frame 600. The transmission assembly shaft 300 of the present invention passes through each hanging basket-type loading mechanism 200 in sequence, and each hanging basket-type loading mechanism 200 is slidably connected to the transmission assembly shaft 300. A driving pulley 305 is mounted on one end of the transmission assembly shaft 300. A forward / reverse motor is mounted on one side of the frame 600. A driving pulley is mounted on the output shaft of the forward / reverse motor. The driving pulley and the driving pulley 305 are connected by a transmission belt. The forward / reverse motor of the present invention drives the transmission assembly shaft 300 to rotate, which in turn drives the various hanging basket-type loading mechanisms 200 to rotate together. During the rotation of the hanging basket-type loading mechanisms 200, the hanging basket-type loading mechanisms 200 move axially along the sintering drum 100. An air-cooled cooling mechanism 400 is provided on one axial side of the sintering drum 100 to cool the sintered material. The working principle and advantages of the present invention are as follows: the present invention controls the rotation of the transmission assembly shaft 300 so that the hanging basket type feeding mechanism 200 rotates in the sintering cylinder 100, and can move along the axial direction of the sintering cylinder 100 during the rotation, thereby making the material to be sintered placed in the hanging basket type feeding mechanism 200 be fully sintered, so that the material to be sintered is in a three-dimensional motion form in the sintering cylinder 100, so that the ceramic body can be fully sintered during the sintering process, avoiding the occurrence of uneven sintering, thereby improving the yield of the sintered material; and after the sintering is completed, the hanging basket type feeding mechanism 200 is moved to the air-cooled cooling mechanism 400 for air cooling, thereby improving the cooling efficiency. After the sintering is completed, the sintered material is taken out by the operator, and then the material to be sintered is placed in the hanging basket type feeding mechanism 200 for the next sintering operation.

[0040] As a preferred embodiment of the present invention, Figure 6-7As shown, the hanging basket type material placement mechanism 200 includes a transmission mounting sleeve 201, which is assembled on the transmission mounting shaft 300 and is slidably connected to the transmission mounting shaft 300. A plurality of fixing rods 203 are mounted on the outer circumference of the transmission mounting sleeve 201. These fixing rods 203 are arranged at intervals along the circumference of the transmission mounting sleeve 201, and each fixing rod 203 extends radially outward along the transmission mounting sleeve 201. In this embodiment, a plurality of hanging basket units are installed on each fixing rod 203 at intervals along its length, and the material to be sintered is placed in the hanging basket unit. The specific structure of the hanging basket unit is as follows: Figure 9 As shown, the hanging basket unit includes two material placement portions 205 , which are respectively arranged on both sides of the fixing rod 203 . Each loading portion 205 includes a mounting rod 2051 and a loading frame 2056. One end of the mounting rod 2051 is fixedly connected to the fixed rod 203, and the axis of the mounting rod 2051 is parallel to the axis of the transmission assembly shaft 300. The loading frame 2056 is movably connected to the mounting rod 2051. The lower end surface of the loading frame 2056 is a mesh structure. The material to be sintered is placed in the loading frame 2056. When the fixed rod 203 rotates with the transmission mounting sleeve 201, the mounting rod 2051 rotates along the circumferential direction of the transmission mounting sleeve 201. During this process, the loading frame 2056 always remains in a vertical state. In this way, the material to be sintered in the loading frame 2056 is prevented from flipping over. Moreover, the material to be sintered can move along the circumferential and axial directions of the sintering cylinder 100 with the loading frame 2056, so that it can be fully sintered in the sintering cylinder 100.

[0041] As a preferred embodiment of the present invention, Figure 10As shown, the material loading frame 2056 includes a frame body, with cantilevers 2052 respectively provided on two opposite sides of the frame body. The lower end of each cantilever 2052 is configured with at least two mounting pins 2053. Mounting holes 2057 are provided on the corresponding side walls of the frame body at positions corresponding to each mounting pin 2053. Each mounting pin 2053 is inserted into the corresponding mounting hole 2057, thereby achieving connection between the cantilever 2052 and the frame body. In this embodiment, the upper end of each cantilever 2052 is configured with a mounting ring, which is movably mounted on the mounting rod 2051. The mounting rod 2051 is configured with a stopper 2054. A limit sleeve 2055 is detachably connected to the end of the mounting rod 2051 away from the fixed rod 203, and the two cantilever arms 2052 are located between the stopper 2054 and the limit sleeve 2055. In this embodiment, the frame can be directly removed from the mounting rod 2051, thereby facilitating frame replacement. That is, the frame can be removed together with the sintered material therein, and another frame containing the material to be sintered can be connected to the mounting rod 2051. The specific operation steps are as follows: rotating the limiting sleeve 2055 so that the limiting sleeve 2055 moves a distance away from the stopper 2054, thereby separating the lower end of the cantilever 2052 from the frame, thereby achieving frame replacement; when the frame is replaced, rotating the limiting sleeve 2055 so that the limiting sleeve 2055 moves toward the stopper 2054 until the mounting pin 2053 on the cantilever 2052 is fixed to the corresponding mounting hole 2057. This embodiment does not flip over during the process of rotating with the fixed rod 203. Specifically, during the process of rotating the mounting rod 2051 with the fixed rod 203, the cantilever 2052 is rotatably connected to the mounting rod 2051 via the mounting ring, thereby maintaining the frame body in a stable state. In this way, the material to be sintered within the frame body does not tilt. In order to enable the frame body to hold the material to be sintered in layers, increase the sintering capacity, and effectively utilize the space of the frame body, this embodiment adopts the following measures: a mesh partition 2058 is provided within the material placement frame 2056, and mounting buckles 2059 are respectively constructed on two opposite sides of the mesh partition 2058. Each mounting buckle 2059 is buckled to a corresponding upper edge of the material placement frame 2056. The lower portion of the mesh partition 2058 forms a placement cavity, and the upper portion of the mesh partition 2058 forms another placement cavity.

[0042] As a preferred embodiment of the present invention, Figure 6-8As shown, a plurality of limiting guide blocks 202 are constructed on the inner wall of the transmission mounting sleeve 201. These limiting guide blocks 202 are arranged at intervals along the circumference of the transmission mounting sleeve 201. A strip guide groove 301 is respectively opened on the outer circumference of the transmission assembly shaft 300 and at a position corresponding to each limiting guide block 202. Each limiting guide block 202 is assembled in the corresponding strip guide groove 301 and can slide in the strip guide groove 301 along the transmission mounting sleeve 201, wherein each strip guide groove 301 extends along the axial direction of the transmission assembly shaft 300 to both ends of the transmission assembly shaft 300. In order to realize the axial movement of the hanging basket type material placing mechanism 200 along the transmission assembly shaft 300 during its rotation, as shown in FIG. Figure 5 As shown, a spiral guide groove 111 is provided on the inner wall of the sintering cylinder 100, and the spiral guide groove 111 spirally extends out of the two ends of the sintering cylinder 100 along the axial direction of the sintering cylinder 100. In this embodiment, a guide column 204 is constructed at the end of at least one fixed rod 203, and the end of the guide column 204 extends into the spiral guide groove 111. In the process of the fixed rod 203 rotating with the transmission mounting sleeve 201, the guide column 204 spirally moves in the spiral guide groove 111, thereby realizing the axial movement of the transmission mounting sleeve 201. The axes of all the fixed rods 203 of this embodiment can be located on the same plane, so that the guide column 204 is constructed on one of the fixed rods 203. This method will cause unstable transmission. In this way, in order to improve the stability of the transmission, as Figure 8 As shown, the fixing rods 203 are fixed on the outer circumferential surface of the transmission mounting sleeve 201, and the arrangement of these fixing rods 203 is adapted to the spiral shape of the spiral guide groove 111. A guide column 204 is fixed on each fixing rod 203, and each guide column 204 is assembled at the corresponding position of the spiral guide groove 111, thereby achieving more stable transmission.

[0043] As a preferred embodiment of the present invention, Figure 5As shown, the sintering cylinder 100 includes a cylinder 101, an electric heating wire is spirally wound around the outside of the cylinder 101, and a layer of thermal insulation layer is coated on the outside of the electric heating wire. In this embodiment, a first cover 107 and a second cover 102 are detachably connected to the axial ends of the cylinder 101, respectively. Specifically, a plurality of first connecting ears A109 are constructed along the circumferential intervals on the first cover 107, and a plurality of first connecting ears B110 are constructed along the circumferential intervals on the outer surface of the corresponding end of the cylinder 101. The first connecting ears A109 are connected to the corresponding first connecting ears B110 by bolts, thereby achieving a closure at one end of the cylinder 101; a plurality of second connecting ears A105 are constructed along the circumferential intervals on the second cover 102, and a plurality of second connecting ears B106 are constructed along the circumferential intervals on the outer surface of the corresponding end of the cylinder 101. The second connecting ears A105 are connected to the corresponding second connecting ears B106 by bolts, thereby achieving a closure at the other end of the cylinder 101. That is, after all the hanging basket type feeding mechanisms 200 enter the cylinder 101, the cylinder 101 is sealed by the first cover 107 and the second cover 102, so that the material to be sintered in the hanging basket type feeding mechanism 200 is sintered in the cylinder 101. In this embodiment, an air outlet pipe 108 is constructed on the first cover 107 to discharge the gaseous products produced by sintering. In this embodiment, transmission ears 103 are respectively constructed on both sides of the second cover 102, and two fixed ears 104 are constructed on the outer surface of the end corresponding to the sintering cylinder 100 and the second cover 102, and the fixed ears 104 are arranged in a one-to-one correspondence with the transmission ears 103. In this embodiment, two threaded screws 303 are used to realize the transmission connection between the second cover 102 and the frame 600. Specifically, as shown in FIG. Figure 2 As shown, the ends of the two threaded rods 303 on the same side are respectively connected to the frame 600 for rotation, and the two threaded rods 303 are parallel to the axis of the transmission assembly shaft 300. The end of each threaded rod 303 away from the frame 600 passes through the corresponding transmission ear 103 and is connected to the fixed ear 104 for rotation, and the threaded rod 303 is threadedly connected to the transmission ear 103. In this embodiment, a transmission sprocket 304 is installed at the end of each threaded rod 303 close to the frame 600, and a double-piece sprocket 302 is installed on the transmission assembly shaft 300. The double-piece sprocket 302 is connected to the two transmission sprockets 304 through two chains. Figure 3As shown, the double-piece sprocket 302 of this embodiment is fixed to the transmission assembly shaft 300 via a locking bolt. When the locking bolt 306 is loosened, the double-piece sprocket 302 and the transmission assembly shaft 300 are released from the fixed connection. In this way, when the transmission assembly shaft 300 rotates, the double-piece sprocket 302 will not rotate. The working principle of this embodiment is as follows: when all the hanging basket type loading mechanisms 200 are located outside the sintering cylinder 100 and each hanging basket type loading mechanism 200 is fully loaded with the material to be sintered, the position of the second cover 102 is close to the frame 600, and then the locking bolt 306 is tightened to fix the double-piece sprocket 302 and the transmission assembly shaft 300. When the transmission assembly shaft 300 is driven to rotate, the double-piece sprocket 302 rotates through the two threaded screw rods 303 of the chain. During the rotation of these two threaded screw rods 303, the second cover 102 is driven to move toward the sintering cylinder 100 through the transmission ear 103, so that the second cover 102 pushes the hanging basket type loading mechanism 200 located on the transmission assembly shaft 300 to gradually enter the sintering cylinder 100. In order to facilitate the hanging basket type loading mechanism 200 to smoothly enter the sintering cylinder 100, when the hanging basket type loading mechanism 200 is close to the sintering cylinder 100, it continues to rotate. The basket-type charging mechanism 200 is configured so that the guide post 204 on the hanging basket-type charging mechanism 200 is aligned with the entrance of the spiral guide groove 111, and then the transmission assembly shaft 300 is stopped from rotating to push the hanging basket-type charging mechanism 200 toward the sintering cylinder 100, so that the guide post 204 on the hanging basket-type charging mechanism 200 enters the entrance of the spiral guide groove 111, and then the transmission assembly shaft 300 is rotated again. This process is repeated to sequentially convey the hanging basket-type charging mechanism 200 into the sintering cylinder 100. When all the hanging basket-type charging mechanisms 200 are completely entered into the sintering cylinder 100, the locking bolt 306 is loosened to release the fixed connection between the double-piece sprocket 302 and the transmission assembly shaft 300, and then the second cover 102 is fixed to the end of the sintering cylinder 100 to seal the sintering cylinder 100. Then, the transmission assembly shaft 300 is driven to rotate forward and reversely to realize the displacement and rotation of the hanging basket-type charging mechanism 200 in the sintering cylinder 100. After sintering is completed, the hanging basket type loading mechanism 200 needs to be guided out of the sintering cylinder 100. Specifically, the second cover 102 is removed, the locking bolt 306 is tightened, the double-piece sprocket 302 and the transmission assembly shaft 300 rotate synchronously, the second cover 102 moves away from the sintering cylinder 100, and the hanging basket type loading mechanism 200 also gradually moves outward. When the second cover 102 moves close to the frame 600, the locking bolt 306 is loosened, and the transmission assembly shaft 300 is continued to be driven to rotate, so that all the hanging basket type loading mechanisms 200 are separated from the sintering cylinder 100.

[0044] As a preferred embodiment of the present invention, Figure 11-13As shown, the air-cooled cooling mechanism 400 includes multiple air-cooling units, which are spaced apart along the axial direction of the transmission assembly shaft 300. A connecting pipe 406 is constructed at the upper end of each air-cooling unit. A distribution pipe 405, which is configured with an air inlet connector 407, is interconnected with each connecting pipe 406. A working space 500 is formed between adjacent air-cooling units. After cooling is completed, an operator can replace materials in the working space 500. The specific structure of the air-cooling unit is as follows: the air-cooling unit includes an arc-shaped outer shell 401, with bases 408 constructed on two opposite sides of the outer shell 401. An arc-shaped air distribution plate 402 is constructed on the inner wall of the outer shell 401. The arc-shaped air distribution plate 402 protrudes inwardly along the radial direction of the outer shell 401 and is covered with air outlet holes 404. An air distribution cavity 403 is formed between the arc-shaped air distribution plate 402 and the outer shell 401. The working principle of this embodiment is as follows: the gas enters the distribution pipe 405 through the air inlet joint 407, and then evenly enters each connecting pipe 406. The gas enters the air distribution cavity 403 through the connecting pipe 406, and the gas is blown onto the hanging basket type loading mechanism 200 through the air outlet holes 404 on the curved air distribution plate 402, thereby achieving the cooling of the sintered material in the hanging basket type loading mechanism 200. In this embodiment, because the curved air distribution plate 402 protrudes radially inward along the outer shell 401, the blown air is in the shape of a fan, thereby achieving the purpose of increasing the cooling area and improving the cooling effect. In addition, this embodiment adopts multiple air cooling units, so that these air cooling units can effectively cover all the hanging basket type loading mechanisms 200, and the gaps between the air cooling units (working space 500) are fully utilized to create a better operating space for the operator.
