Description

Technical Field

[0001] This utility model belongs to the technical field of refractory brick production equipment, specifically relating to an automatic feeding device for producing refractory bricks. Background Technology

[0002] Refractory bricks, also known as fire bricks, are refractory materials made by firing refractory clay or other refractory raw materials. During processing, the raw materials need to be poured into a molding die and pressed into shape by the molding die.

[0003] Chinese Patent CN220011030U discloses a quantitative feeding device for a refractory brick making machine, including a screw conveyor and a feeding hopper connected to the feeding end of the screw conveyor. A temporary storage box is fixedly installed at the discharge end of the screw conveyor. The bottom of the temporary storage box has a bucket-shaped structure. A distribution pipe is fixedly connected to the bottom of the temporary storage box. The bottom of the distribution pipe is connected to the discharge hopper. A rotating rod is rotatably installed inside the distribution pipe. A storage hopper is opened inside the rotating rod. By rotating the rotating rod, the storage hopper can be connected to the temporary storage box and the discharge hopper respectively. One end of the storage hopper is connected to the side wall of one end of the rotating rod. A slider is slidably installed inside the storage hopper. This utility model can transport the powder in the feeding hopper to the temporary storage box through the screw conveyor. When the rotating rod rotates, the powder in the temporary storage box can be quantitatively transported to the discharge hopper through the storage hopper and discharged through the discharge port, realizing intermittent quantitative powder delivery.

[0004] However, in actual use, due to the different working heights of different pressing equipment, the required feeding height will also be different. Too high a feeding height will cause a lot of splashing when the raw material falls, while too low a feeding height will prevent normal feeding. The feeding structure in the above solution cannot adjust the feeding height, resulting in a limited range of pressing equipment models that can be adapted, that is, a small applicable range, which is not conducive to actual use. Utility Model Content

[0005] The present invention aims to provide an automatic feeding device for the production of refractory bricks, so as to solve the problem of the limited applicability of the existing feeding devices mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for producing refractory bricks, comprising...

[0007] The screw conveyor has a hopper installed on its side wall and a feeding mechanism at its output end.

[0008] The height adjustment mechanism includes mounting rings, a support frame, a height adjustment component, and a base plate. Two mounting rings are fixed to the outside of the screw conveyor, and the two mounting rings are respectively hinged to the support frame and the height adjustment component. The height adjustment component is located on the side of the support frame near the hopper. The bottom of both the height adjustment component and the support frame is equipped with a base plate.

[0009] The principle and effects of this technical solution:

[0010] 1. By using two mounting rings, a support frame, a height adjustment component, and a base plate, the screw conveyor mechanism is mounted on the support frame and height adjustment component. The support frame and height adjustment component are in contact with the ground and cannot rotate. Furthermore, by changing the overall height of the height adjustment component, the screw conveyor can rotate around the hinged end of one side of the support frame, thus controlling the tilt angle of the screw conveyor. By controlling the tilt angle of the screw conveyor, the height of the output end of the screw conveyor is changed, which in turn changes the height of the feeding mechanism, adapting to different models of pressing equipment and improving its applicability.

[0011] 2. After the refractory raw materials are added into the screw conveyor through the feeding hopper, the screw conveyor mixes and transports the refractory raw materials to the feeding mechanism, so that the feeding mechanism can feed the pressing equipment.

[0012] The present invention is further configured such that: the height adjustment component includes a lower fixed frame, an upper fixed frame, a screw and a turntable, the upper fixed frame is inserted into the lower fixed frame, the upper end of the upper fixed frame is hinged to the mounting ring, the bottom of the lower fixed frame is mounted with a base plate, the screw is threaded into the lower fixed frame, and the top end of the screw is rotatably connected to the upper fixed frame, and the bottom end of the screw is connected to the turntable.

[0013] The principle and effect of this technical solution: By setting up a lower fixed frame and an upper fixed frame, the upper fixed frame can slide up and down along the lower fixed frame. By setting up a screw and a turntable, the user can control the height of the screw relative to the lower fixed frame by rotating the turntable. By changing the height of the screw, the height of the upper fixed frame relative to the lower fixed frame is changed. Furthermore, by changing the overall height of the height adjustment component, the tilt angle of the screw conveyor can be controlled.

[0014] The present invention is further provided that: a movable wheel is installed at the bottom of the base plate.

[0015] The principle and effect of this technical solution: The addition of casters makes the device easier to move and adjust.

[0016] The present invention is further configured such that: the feeding mechanism includes a feeding hopper and a telescopic support, the feeding hopper is installed on the top of the telescopic support, the top of the feeding hopper corresponds to the output end of the screw conveyor, and the bottom of the telescopic support has rollers.

[0017] The principle and effect of this technical solution: By installing the feeding hopper on the telescopic support and installing rollers at the bottom of the telescopic support, the position of the feeding hopper can be easily moved on the ground, and the height of the feeding hopper can be adjusted by adjusting the height of the telescopic support, thereby adapting to the output end of the screw conveyor of different heights.

[0018] The present invention is further configured such that the feeding mechanism also includes a vibration motor, which is installed on the side wall of the feeding hopper.

[0019] The principle and effect of this technical solution: By setting up a vibration motor, the vibration motor can drive the feeding hopper to vibrate slightly, thereby avoiding the refractory material from adhering to the inner wall of the feeding hopper and improving the flowability of the refractory material in the feeding hopper.

[0020] The present invention is further configured such that: the feeding hopper has a temporary storage chamber, a control chamber and a discharge port from top to bottom; the bottom of the temporary storage chamber has a through hole that communicates with the control chamber; the discharge port is connected to the control chamber; a control component is installed inside the control chamber; and the control component is used to close the through hole.

[0021] The principle and effect of this technical solution: By controlling the opening and closing of the through hole through the control component, the refractory material in the temporary storage cavity enters the control cavity and the discharge port. By controlling the discharge amount in the temporary storage cavity, the function of precise feeding is achieved, reducing the subsequent manual operation required and saving manpower.

[0022] The present invention is further configured such that: the control component includes a push rod, a first slider, an electric telescopic rod, and a second slider; the push rod is installed in the control cavity; the first slider is installed at the movable end of the push rod; the electric telescopic rod is fixed inside the first slider; and the second slider is connected to the movable end of the electric telescopic rod; the first slider and the second slider are respectively slidably engaged with the control cavity; and the second slider is located on the side of the first slider near the material discharge port.

[0023] The principle and effect of this technical solution: The first slider and the second slider are connected by an electric telescopic rod, and the distance between the first slider and the second slider can be adjusted, which controls the capacity of the refractory material entering the first slider and the second slider. By controlling the capacity, the weight of the refractory material that can fall from the discharge port can be controlled, thereby achieving the purpose of precise feeding. Furthermore, the push rod drives the first slider, the electric telescopic rod and the second slider to move as a whole, so that the cavity between the first slider and the second slider can correspond to the through hole or the discharge port respectively, thereby playing the functions of receiving and discharging materials. Moreover, after the first slider blocks the through hole, the refractory material in the temporary storage cavity can be temporarily prevented from entering the control cavity.

[0024] The present invention is further configured such that the control cavity is arranged at an angle, and the end of the control cavity near the material discharge port is lower than the end of the control cavity away from the material discharge port.

[0025] The principle and effect of this technical solution: By tilting the control chamber, the refractory material will spontaneously slide along the inclined surface after entering the control chamber from the temporary storage chamber, thus accumulating on the side near the first slider. This avoids the situation where the refractory material accumulates directly below the through hole after entering the control chamber through the through hole, thus preventing the subsequent refractory material from entering the control chamber. In addition, the tilting setting makes it easier for the refractory material to enter the discharge port. Attached Figure Description
