Description

Technical Field

[0001] The utility model relates to the technical field of silicon carbide ceramic production, in particular to a kiln feeding rack used for silicon carbide ceramic production. Background Art

[0002] Silicon carbide ceramic production includes raw material preparation, powder production, molding and sintering. A kiln is a device used for sintering, drying, annealing, heat treatment and other heating treatments. It is an essential facility in pottery molding and a furnace for firing ceramic objects and sculptures or fusing enamel to the surface of metal objects. The kiln feed rack is a device used to support and transport materials to be fired. It is a feeding device specially designed for kilns in the production process of silicon carbide ceramics.

[0003] According to patent number CN217737874U, a feeding structure of an LFP firing kiln is disclosed. The patent includes a bracket and a kiln body. A cavity is provided on the bracket, and a feeding mechanism is provided in the cavity. The feeding mechanism includes a motor, a rotating shaft, a conveyor belt, a gear, and a transmission roller. The motor is configured as a stepping motor, which is arranged on the side wall of the bracket. One end of the rotating shaft is connected to the output shaft of the motor, and the other end of the rotating shaft is rotatably arranged on the side wall of the bracket. Both ends of the transmission roller are rotatably arranged in the cavity, the conveyor belt is arranged on the transmission roller and the rotating shaft, and the gear is arranged on the rotating shaft and the transmission roller. The utility model changes the previous continuous material conveying mode into a stepping conveying mode by arranging a stepping motor, so that the material can stay longer in the concentrated flame area in the firing section, thereby improving the firing efficiency of the material.

[0004] However, during the use of the above-mentioned patent, the size of materials for producing silicon carbide ceramics is inconsistent due to different customer needs. However, the size of the feed port on the kiln body is fixed, which results in that materials of different volumes can enter the kiln body for firing, and the high-temperature firing time of materials of different volumes is also different. As a result, after materials of different volumes are fired for the same time, the number of defective products will increase, and if it is found that the fired materials are unqualified in subsequent processes, they need to be reworked, which seriously affects work efficiency.

DETAILED DESCRIPTION

[0025] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0026] See also Figures 1 to 5 The utility model provides a technical solution: a kiln feed rack for silicon carbide ceramic production, comprising a bracket 1, a transmission roller 2 and a kiln body 3, wherein the top of the bracket 1 is internally connected with the transmission roller 2, and the middle of the top of the bracket 1 is butt-jointed with the kiln body 3; an electric push rod 4 is installed in the middle of the top of the kiln body 3, and the output end of the electric push rod 4 is butt-jointed with a toothed plate 5, and the outer wall of the toothed plate 5 is slidably connected with a slide rail 6; the top of the toothed plate 5 is meshedly connected with a gear 7, and the gear 7 is internally butt-jointed with a rotating column 8, and the rotating column 8 Transmission rods 9 are butt-jointed on both sides of the outer wall; the top end of the transmission rod 9 is slidably connected to a limit plate 10, and the outer wall of the limit plate 10 is slidably connected to a limit seat 11, and the outer wall of the limit seat 11 is welded to the kiln body 3; one side of the outer wall of the limit plate 10 is connected to an electric push column 12 through a fixed seat, and the output end of the electric push column 12 is butt-jointed with a guide plate 13; the bottom end of the slide rail 6 is welded to the kiln body 3, and the side of the rotating column 8 away from the gear 7 is connected to the kiln body 3 through a bearing seat, and the transmission rollers 2 are evenly distributed on the bracket 1.

[0027] In the process of producing silicon carbide ceramics through the kiln feed rack, in order to prevent materials with inconsistent volumes from entering the kiln body 3, the electric push rod 4 is first started. Since the output end of the electric push rod 4 is connected to the toothed plate 5, the electric push rod 4 contracts and drives the toothed plate 5 to move along the slide rail 6. Since the toothed plate 5 and the gear 7 are meshed, the movement of the toothed plate 5 drives the gear 7 to rotate counterclockwise. Then the rotation of the gear 7 drives the rotating column 8 to rotate. Since the rotating column 8 is connected to the transmission rod 9, the rotation of the rotating column 8 drives the transmission rod 9 to rotate together. Since the top of the transmission rod 9 is in sliding connection with the limit plate 10, the transmission rod 9 rotates counterclockwise and drives the limit plate 10 to move downward.

[0028] And because the limit seat 11 and the limit plate 10 are in sliding connection, the movement of the limit plate 10 is guided until the limit plate 10 moves down to the specified position, and then the size of the feed port is changed, so that the materials exceeding the volume of the feed port are blocked, and at this time, the electric push column 12 is started to contract and drive the guide plate 13 to move, and then the materials with too large volume are pushed away from the center of the transmission roller 2. At this time, the staff removes it from the transmission roller 2 to prevent it from interfering with the movement of subsequent materials, thereby preventing materials of different volumes from entering the kiln body 3 for firing, which in turn leads to an increase in the number of defective products, causing the staff to rework and affect work efficiency. Therefore, when the kiln feed rack is used in the production of silicon carbide ceramics, it is convenient to change the opening size and improve work efficiency. Embodiment 2

[0029] See also Figure 1 , Figure 2 , Figure 6 and Figure 7The utility model provides a technical solution: a kiln feeding rack for the production of silicon carbide ceramics, a driving motor 14 is installed on one side of the middle part of the outer wall of the bracket 1, and the output end of the driving motor 14 is connected to the first synchronous roller 15; the first synchronous roller 15 is connected to the second synchronous roller 17 through a synchronous belt 16, and the side of the bracket 1 close to the first synchronous roller 15 is connected to a cleaning scraper 18 through a support seat 19; the bottom end of the bracket 1 is connected to a collecting box 20 through a support plate, and the bottom end of the support seat 19 is welded to the bracket 1; the inside of the support seat 19 is connected to the cleaning scraper 18, the outer wall of the second synchronous roller 17 is connected to the synchronous belt 16, and the top of the cleaning scraper 18 is in contact with the outer wall of the synchronous belt 16.

[0030] In the process of producing silicon carbide ceramics through the kiln feed rack, in order to reduce the workload of the staff for cleaning, the broken materials dropped during the movement of the materials on the transmission rollers 2 first pass through the gaps between the transmission rollers 2 and fall onto the synchronous belt 16, and then the drive motor 14 is started to drive the first synchronous roller 15 to rotate. Since the first synchronous roller 15 is connected to the second synchronous roller 17 through the synchronous belt 16, the first synchronous roller 15 rotates and drives the synchronous belt 16 to rotate through the second synchronous roller 17, thereby moving the waste on the synchronous belt 16 to the drive motor 14;

[0031] And because the top of the cleaning scraper 18 is in contact with the synchronous belt 16, the cleaning scraper 18 inside the support seat 19 rubs against the synchronous belt 16, and then the debris adhering to the synchronous belt 16 is scraped off and guided to the collection box 20, and then collected and processed by the collection box 20, thereby preventing the debris from accumulating under the drive roller 2, thereby facilitating the collection and processing of the debris when used in the kiln feed rack for the production of silicon carbide ceramics.

[0032] In actual use, when the kiln feed rack for the production of silicon carbide ceramics is used, the kiln body 3 is started first, and then the green body obtained through the molding process is placed on the bracket 1, and then the green body is transported to the inside of the kiln body 3 by the rotation of the transmission roller 2. At this time, the material is fired by the high temperature generated by the kiln, and then the material for producing silicon carbide ceramics is sintered at high temperature. This is the existing technology and will not be elaborated on here.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
