Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , this embodiment provides a bread brick pressing device, including a pressing table 1, and the reference model of the pressing table 1 is a brick making machine of model HJS-9000. A mold 2 and a pressing plate 3 are slidably installed up and down inside the pressing table 1. The pressing plate 3 is located above the mold 2, and both the mold 2 and the pressing plate 3 are controlled to move by hydraulic rods. The mold 2 is provided with a plurality of mold holes, and the lower end of the pressing plate 3 is fixedly connected with a plurality of pressing rods, and the pressing rods are aligned with the mold holes up and down.

[0023] During use, place a backing plate on the pressing table 1, move the mold 2 downward so that the mold 2 is pressed against the backing plate, inject brick raw materials into the mold holes of the mold 2, and then control the pressing plate 3 to move downward so that the pressing rods extend into the mold holes of the mold 2, and the raw materials in the mold holes can be extruded. After the raw materials are extruded and formed, bread bricks can be formed.

[0024] As Figure 1 shown, a material injection mechanism 4 is installed on the side of the pressing table 1. The material injection mechanism 4 includes a side frame 41, a sliding frame 42 and a sliding plate 43. Among them, the side frame 41 is fixedly connected to the side of the pressing table 1, and the sliding frame 42 is slidably installed at the upper end of the side frame 41. As Figure 3As shown, a telescopic rod 411 is installed inside the side frame 41. The telescopic rod 411 is set as a hydraulic rod. One end of the output rod of the telescopic rod 411 is fixedly connected inside the sliding frame 42. By extending the hydraulic rod, the sliding frame 42 can be driven to move towards the mold 2. After the telescopic rod 411 is fully extended, the sliding frame 42 slides and fits above the mold 2. The sliding frame 42 is set as a hollow square frame structure. A sliding plate 43 is slidably installed at the lower end of the sliding frame 42. Side plates are fixedly connected to the lower edge of the sliding frame 42. One end of the side plate and the sliding plate 43 is fixedly connected with a spring 421, and the spring 421 applies an elastic force to the sliding plate 43.

[0025] The sliding plate 43 covers the lower end of the sliding frame 42. After injecting raw materials into the sliding frame 42, the sliding plate 43 prevents the raw materials from leaking out. After controlling the sliding frame 42 to slide towards the mold 2, one end of the sliding plate 43 contacts the side of the mold 2. As the sliding frame 42 continues to move, the mold 2 applies a reverse force to the sliding plate 43, and the sliding plate 43 will slide below the sliding frame 42. At the same time, the spring 421 is compressed. After the sliding plate 43 slides to expose the lower part of the sliding frame 42, the raw materials in the sliding frame 42 leak out from below the sliding frame 42 due to their own weight and then fall into the die holes of the mold 2. After the telescopic rod 411 contracts, the lower end of the sliding plate 43 levels the upper end of the mold 2 to prevent excess raw materials from appearing at the upper end of the mold 2. When the sliding plate 43 detaches from the mold 2, it moves to close the lower end of the sliding frame 42 through the elastic force of the spring 421, thereby preventing the raw materials from leaking out.

[0026] The length of the spring 421 is relatively long, and it is easy to bend after being compressed. Therefore, one end of the sliding plate 43 is fixedly connected with a limiting rod 431. The limiting rod 431 slidably penetrates the side plate at the lower end of the sliding frame 42, and the spring 421 is sleeved on the outer side wall of the limiting rod 431. The limiting rod 431 is used to limit the spring 421 to prevent the spring 421 from bending.

[0027] However, during the actual operation of the pressing device by the applicant, it was found that the raw materials put into the sliding frame 42 are sticky. The raw materials located below are squeezed by their own gravity, which leads to adhesion and condensation of the raw materials. After the adhesively condensed raw materials enter the die holes of the mold 2, multiple voids will be generated, that is, the raw materials cannot fill the die holes. In order to prevent the raw materials in the sliding frame 42 from sticking, a blanking mechanism 5 for vibrating the raw materials is arranged in the sliding frame 42. Among them, the blanking mechanism 5 includes a wire mesh frame 51, a turntable 52 and a motor 53, as Figure 3As shown, the motor 53 is set as a servo motor. The motor 53 is fixedly connected to the upper end of the sliding frame 42. The turntable 52 is fixedly connected to the output shaft of the motor 53. The wire frame 51 is movably installed in the sliding frame 42. Among them, one end of the wire frame 51 is rotatably connected to a short rod 511, and the other end of the short rod 511 is rotatably connected to the lower edge of the inner side wall of the sliding frame 42. The edge of the end face of the turntable 52 is rotatably connected to a long rod 521, and the long rod 521 is rotatably connected to one end of the wire frame 51 away from the short rod 511. When in use, the motor 53 is started to drive the turntable 52 to rotate, and then the long rod 521 drives one end of the wire frame 51 to shake up and down. At this time, the short rod 511 rotates to compensate for the movement of the wire frame 51. When the short rod 511 rotates to the lowest position as Figure 5 shown, and the position where the short rod 511 rotates to the highest position is as shown by the dotted line in Figure 5 . With the rotation compensation of the short rod 511, the wire frame 51 can be driven to vibrate in the sliding frame 42. The vibrating wire frame 51 stirs and agitates the raw materials in the sliding frame 42, thereby preventing the raw materials from sticking. Small pieces of raw materials can also evenly fill the die holes of the die 2 when they fall into the die holes of the die 2.

[0028] As shown in Figure 2 and Figure 3 , a sensor 422 is fixedly connected to the edge of the lower end of the sliding frame 42 on the side away from the sliding plate 43. The sensor 422 is set as a pressure sensor, and the reference model is the pressure sensor CPR-16. The normally closed contact of the pressure sensor is connected in series in the contactor coil circuit. When the pressure is high, the contact closes and the motor starts. When the pressure is low, the contact disconnects and the motor stops running. After the sliding frame 42 completely covers the die 2, the sliding plate 43 contacts the sensor 422 and applies pressure to the sensor 422, thereby triggering the sensor 422 to work. The sensor 422 is connected to the motor 53 by wires, and the sensor 422 can start the motor 53.
