Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refractory brick feeding structures, in particular to a feeding device for refractory brick production. Background Art
[0002] Refractory bricks are shaped refractory materials. When they are processed, they are generally die-casted by a die-casting machine, and the die-casting machine is generally fed with an automatic feeder.
[0003] The automatic feeder generally includes a silo for storing raw materials, a weighing hopper is provided below the outlet for weighing, and a movable feeding arm with a feeding hopper provided on the feeding arm. The feeding hopper is driven by the feeding arm to move back and forth between the weighing hopper outlet and the top of the lower mold of the die-casting machine. When in use, the silo feeds material into the weighing hopper, the weighing hopper receives the material and weighs it. After reaching the required weight, feeding into the weighing hopper is stopped, and then the feeding arm drives the feeding hopper to the bottom outlet of the weighing hopper to receive the material, and then sends it to the position above the lower mold of the die-casting machine to feed the raw materials to the lower mold.
[0004] However, when feeding some longer bricks, the hopper relies on the natural drop of raw materials into the hopper when receiving the materials, which usually results in the raw materials being higher in the middle and lower on both sides. Therefore, when feeding the materials to the lower mold, the raw materials are also higher in the middle and lower on both sides in the lower mold. As a result, during die-casting, the uneven distribution of raw materials may easily lead to the problem that the pressed bricks are slightly thicker in the middle and thinner on both sides. Therefore, improvement is needed. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0025] Reference Figure 1-4 A feeding device for refractory brick production includes a feeding hopper 6, a scraper 14 is provided on the upper part of the feeding hopper 6, the scraper 14 is moved horizontally back and forth by a moving mechanism, the moving mechanism is fixedly arranged on the outer side of the feeding hopper 6, and a lifting mechanism is provided on the moving mechanism for driving the scraper 14 to move up and down. The scraper 14 is arranged on the lifting mechanism, and a flat door mechanism is provided at the bottom of the feeding hopper 6.
[0026] In a specific embodiment of the present invention, the moving mechanism can drive the scraper 14 to perform horizontal reciprocating motion left and right in the feed hopper 6, so that the raw materials in the feed hopper 6 can be flattened, making the raw materials more evenly distributed, and with the swing door mechanism, the door can be quickly opened after the feed hopper 6 is above the lower mold. Since the door is opened in a swing manner, the raw materials can be freely fallen into the lower mold at the same time to a certain extent, so that the raw materials entering the lower mold can be kept as close to the spread state in the feed hopper 6 as possible, so that the raw materials falling into the lower mold are relatively evenly distributed. During the die-casting process, the force is evenly applied and the thickness of the finished product is also relatively uniform, so that the overall strength of the finished bricks can be not much different; the lifting mechanism can drive the scraper 14 to move up and down, so that the scraper 14 can adapt to the height of the raw materials in the feed hopper 6.
[0027] The moving mechanism includes a guide rail 12, a lead screw 11, a slider 8 and a motor 3. The lead screw 11 is rotatably arranged in the guide rail 12, and the slider 8 is slidably arranged in the guide rail 12 and is threadedly connected to the lead screw 11.
[0028] The inside of the guide rail 12 is square, and the shape of the slider 8 located inside the guide rail 12 is also square, so as to avoid relative rotation between the slider 8 and the guide rail 12; since the screw 11 and the slider 8 are threadedly connected, when the screw 11 rotates, the slider 8 cannot rotate due to the restriction of the guide rail 12, so the slider 8 will move horizontally inside the guide rail 12.
[0029] The motor 3 is fixedly arranged at the end of the guide rail 12, and the output shaft of the motor 3 is fixedly connected to the end of the screw 11; a through hole is provided at one end of the guide rail 12 on which the motor 3 is mounted, and the end of the screw 11 passes through the through hole and is connected to the output shaft of the motor 3, so that when the motor 3 is working, its output shaft can drive the screw 11 to rotate; a stepper servo motor can be selected for the motor 3, which has the advantage that the speed can be precisely controlled.
[0030] There are two groups of moving mechanisms, one group of guide rails 12 is fixedly set on the front end surface of the feeding hopper 6, and the other group of guide rails 12 is fixedly set on the rear end surface of the feeding hopper 6; the motors 3 in the two groups of moving mechanisms move synchronously.
[0031] The lifting mechanism includes a limit rod 7, a slide 10 and a hydraulic rod 9. There are two limit rods 7, both of which are fixed on the slider 8. The slider 10 is slidably set on the two limit rods 7. The bottom end of the hydraulic rod 9 is fixedly connected to the slider 8, and the top end is fixedly connected to the slider 10.
[0032] The slide plate 10 can slide up and down on the two limit rods 7 driven by the hydraulic rod 9, and since the limit rods 7 and the hydraulic rod 9 are both arranged on the slider 8, when the slider 8 moves, the entire lifting mechanism will also move with the movement of the slider 8.
[0033] There are two groups of lifting mechanisms, corresponding to two groups of moving mechanisms respectively. A connecting shaft 13 is fixedly provided on the top of the scraper 14, and the two ends of the connecting shaft 13 are fixedly connected to the two slides 10 respectively; the hydraulic rods 9 in the two groups of lifting mechanisms move synchronously, so that the two slides 10 can move up and down, and then drive the connecting shaft 13 to move up and down, thereby changing the up and down position of the scraper 14.
[0034] The casement door mechanism includes a door panel 5, a telescopic cylinder 2 and a limit slot 4. The limit slot 4 is arranged on the side of the feeding hopper 6. A limit block 15 matching the limit slot 4 is fixedly provided on the door panel 5. The telescopic cylinder 2 is fixedly connected to the feeding hopper 6, and the telescopic end of the telescopic cylinder 2 is fixedly connected to the door panel 5; there are two door panels 5, each of which is provided with a telescopic cylinder 2 and a limit block 15, and they are symmetrically arranged; one door panel 5 corresponds to two telescopic cylinders 2, and are respectively located on both sides of the feeding hopper 6, and there are also two limit slots 4, which are respectively located on both sides of the feeding hopper 6. Similarly, one door panel 5 corresponds to two limit blocks 15; the limit block 15 is slidably connected in the limit slot 4. When in use, the telescopic rod of the telescopic cylinder 2 is used to drive the door panel 5 to move horizontally, and when moving, under the action of the limit block 15 and the limit slot 4, the door panel 5 can move according to a specific path.
[0035] The feeding hopper 6 is fixedly arranged at the front end of the feeding arm 1, and the feeding arm 1 is a movable feeding arm 1 of the automatic feeder; the automatic feeder can adopt existing conventional equipment, and its working principle and working state are all existing technologies, which will not be described in detail here.
[0036] Working process: First, the feeding hopper 6 is driven by the feeding arm 1 to move to the bottom of the outlet of the automatic feeder weighing hopper. At this time, the scraper 14 is driven by the moving mechanism to move to one side of the feeding hopper 6. After the weighing hopper has finished feeding the material into the feeding hopper 6, the feeding arm 1 drives the feeding to move to the position above the entrance of the lower mold. During the movement, the lifting mechanism drives the scraper 14 to move upward so that the bottom end of the scraper 14 is higher than the raw material in the feeding hopper 6. Then, the scraper 14 is driven to move to the middle position of the feeding hopper 6. Then, the lifting mechanism drives the scraper 14 down and moves. The driving mechanism then drives the scraper 14 to move horizontally toward one side of the feed hopper 6. After moving to one side of the feed hopper 6, it moves in the opposite direction to move the scraper 14 to the other side of the feed hopper 6, completing the leveling of the raw materials in the feed hopper 6. When the feed hopper 6 is located above the entrance of the lower mold and the raw materials are also leveled, the telescopic cylinder 2 drives the door panel 5 to open quickly, allowing the raw materials to fall freely into the lower mold. Since the door opens quickly and horizontally, it can avoid the raw materials from piling up again in the lower mold to a certain extent, so that the pressed bricks are more uniform.
