Description

Technical Field

[0001] The invention relates to the technical field of brick presses, in particular to a brick press with a gravity adjustment function for easy demoulding. Background Art

[0002] Brick press is a kind of construction machinery and equipment, which is mainly used to press various raw materials (such as wet soil, cement mixture, fly ash, coal gangue, slag, etc.) into bricks of various shapes and specifications through mechanical force. According to different technical types and application scenarios, there are many types of brick presses, such as eight-hole disc brick presses, vibrating block machines, hydraulic brick presses, and fully automatic brick presses. It is an important production equipment in the building materials industry, which can efficiently convert waste materials into valuable building materials.

[0003] For example, the patent document with publication number CN110666933B discloses an easily adjustable brick press with a quantitative control function. The brick press can convey a user-set quantitative production material from the bottom of the silo to the die box through a feeding mechanism to ensure the production quality of bricks. Moreover, after the pressing mechanism presses the bricks, it separates the sealing plate and the die box through a lifting assembly, and the pressing assembly and the separation assembly cooperate to separate the bricks from the die box and the sealing plate, and continue to load raw materials into the die box so that the equipment can continue to produce and operate, thereby ensuring the production efficiency of the equipment and improving practicality.

[0004] However, the existing brick presses similar to the above application still have the following shortcomings:

[0005] Existing brick presses usually have the problem of inconvenient demoulding, which not only affects production efficiency, but also makes it easy for bricks to partially fail to be smoothly ejected from the mold, resulting in a reduction in the yield rate. In particular, if the bricks cannot be ejected from the mold for a long time, it will cause continuous pressure on the mold, accelerating the wear and damage of the mold. In addition, since the mold is a key component of the brick press, its damage will directly affect the quality and output of the bricks, and replacing and repairing the mold will also increase additional costs and time.

[0006] Therefore, it is urgent to improve this shortcoming. The present invention studies and improves the existing structure and shortcomings, and provides a brick press with a gravity adjustment function that is convenient for demoulding. Summary of the invention

The counterweight plate will gradually move downward under the action of gravity, and eject the pressed bricks in the lower die of the mold from the downward opening to achieve demolding. Since the counterweight plate has a gravity adjustment function, it effectively avoids the bricks being violently ejected directly after the lower die of the mold is turned over. The gradual ejection method not only facilitates the demolding of the bricks, but also avoids damage to the bricks caused by excessive demolding force, which helps to protect the integrity of the bricks.

[0020] 2. The present invention is provided with a buffer component. When the lifting cylinder drives the upper die of the mold to move downward, the first spring is compressed and contracted. At the same time, the pressure sensor senses the pressure change of the upper die of the mold in real time until the pressure reaches the set value and stops pressing down. The pressing force can be strictly controlled by the buffer component, which can effectively avoid the pressing force being too large or too small to affect the brick forming. A guide rod and a guide groove block are provided. As the upper die of the mold moves downward, the guide rod is inserted into the guide groove block to guide the upper die of the mold, so that the upper die of the mold can move downward smoothly and be accurately inserted into the lower die of the mold, which helps to press the material evenly and stably. In conjunction with the support component, the lower die of the mold can remain stable during the pressing process, further improving the brick pressing and forming effect.

The shape and size of the counterweight plate 703 match the shape and size of the lower mold 6 of the mold, and the bottom of the demoulding component 7 is connected with an adjusting component 8, which includes a mounting frame 801, a control motor 802 and a driving gear 803. The outer wall of the mounting frame 801 is fixedly connected to the outer wall of the lower mold 6 of the mold, and the control motor 802 is fixedly installed on the inner surface of the mounting frame 801, and the output shaft of the control motor 802 is fixedly connected to the driving gear 803 through a coupling. The adjusting component 8 also includes a fixing frame 804 and a driven gear 805. The fixing frame 804 is welded to the inner surface of the mounting frame 801 and fixed. The top of the frame 804 is movably connected to a driven gear 805 through a bearing, and the adjustment component 8 also includes a second spring 806, a connecting piece 807, a wire rod 808, and a limit plate 809.

[0033] In summary, combined Figure 1-Figure 6 As shown, the working principle of the brick press with gravity adjustment function for easy demoulding is as follows: first, the material is poured into the lower mold 6 of the mold, and the electric push rod 902 is used to drive the pad 903 to move downward and support it on the ground, and then the lifting cylinder 2 is started, and the upper mold 4 of the mold is driven to move downward by the lifting cylinder 2, and the material in the lower mold 6 of the mold is pressed into bricks by the upper mold 4 of the mold. During the downward movement of the upper mold 4 of the mold, the first spring 303 is compressed and contracted. At the same time, the pressure sensor 302 will sense the pressure change of the upper mold 4 of the mold in real time until the pressure reaches the set value, and the lifting cylinder 2 stops controlling the upper mold 4 of the mold to continue to press down. In this process, as the upper mold 4 of the mold moves downward, the guide rod 5 is inserted into the guide groove block 11 to guide the upper mold 4 of the mold. After the material in the lower mold 6 of the mold is pressed into bricks, it is driven by the electric push rod 902 The foot pad 903 moves up and leaves the ground, and then moves along the guide rail 1004 through the electric control slider 1003, driving the mold lower mold 6 to move out from under the control head 1, and then the mold lower mold 6 is flipped 180 degrees by rotating the controller 1002, so that the mold lower mold 6 opens downward, and then the driving gear 803 is driven to rotate by the control motor 802, and the driving gear 803 and the driven gear 805 are engaged and transmitted to drive the metal wire rod 808 to rotate, so that it is rotated out from the inside of the fixed frame 804, and the tension of the second spring 806 is adjusted by adjusting the length of the second spring 806, so that the gravity of the counterweight plate 703 in the mold lower mold 6 that is balanced by the tension of the second spring 806 is gradually restored, and gradually moves downward under the action of gravity, and the bricks pressed in the mold lower mold 6 are ejected from the downward opening, so that multiple bricks are demolded simultaneously.
