Description

Technical Field

[0001] This utility model relates to the field of coal gangue brick production and processing, and in particular to a high-efficiency molding machine for coal gangue brick production. Background Technology

[0002] With the advancement of energy conservation and environmental protection policies and the deepening of the concept of comprehensive utilization of mineral resources, the resource utilization of coal gangue, a solid waste generated during coal mining, has become one of the key research directions in the industry. Processing coal gangue into coal gangue bricks can not only effectively reduce environmental pollution and land occupation caused by coal gangue stockpiling, but also replace traditional clay bricks, reducing the consumption of arable land resources, and has significant economic, social, and environmental benefits.

[0003] The molding machine is the core equipment in the coal gangue brick production process, and its performance directly determines the molding quality, production efficiency, and production cost of the coal gangue bricks. Existing coal gangue brick molding machines typically include a frame, a pressing mechanism, and a mold. The pressing mechanism applies pressure to the coal gangue raw material in the mold to complete the preparation of the coal gangue bricks.

[0004] However, existing coal gangue brick forming machines still have many shortcomings in practical applications, especially in the filling process. Most existing forming machines use a single hopper structure for filling, directly feeding material into the forming cavity of the mold. Since molds typically have multiple forming cavities for mass production, a single hopper cannot guarantee a uniform filling amount in each cavity. This easily leads to some cavities having too much material and others too little, resulting in uneven thickness and density differences in the formed coal gangue bricks, and a low product qualification rate. Therefore, it is necessary to propose a high-efficiency forming machine for coal gangue brick production to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a high-efficiency molding machine for coal gangue brick production, so as to solve the problems of uneven filling and low product qualification rate in the existing coal gangue brick molding machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency molding machine for producing coal gangue bricks, comprising a frame, a pressing mechanism disposed on the top of the frame, a mold disposed in the middle of the frame, and a high-efficiency filling mechanism. The high-efficiency filling mechanism includes a material box with openings at both the top and bottom. The material box is disposed below the discharge port of the feeding conveyor belt. A material distribution plate is disposed inside the material box. A plurality of material bins are disposed on the material distribution plate. The number of material bins is equal to the number of molding cavities of the mold, and the positions of the material bins correspond one-to-one with the positions of the molding cavities. The bottom of the material bins is flush with the bottom of the material distribution plate.

[0007] Preferably, a third hydraulic rod is installed on the material distribution plate, and a flat plate is fixedly installed at the output end of the third hydraulic rod. The bottom end of the flat plate is attached to the top end of the material distribution plate, and the third hydraulic rod is used to drive the flat plate to move horizontally back and forth on the material distribution plate.

[0008] Preferably, a side frame is provided on one side of the frame, the material box is slidably installed on the side frame, the material box can slide horizontally on the side frame, a cylinder is installed on one side of the material box, a sealing plate is fixedly installed on the output end of the cylinder, the top end of the sealing plate is in contact with the bottom end of the material box, a first hydraulic rod is installed on the side frame, and the output end of the first hydraulic rod is connected to the material box.

[0009] Preferably, the frame includes four guide columns arranged in a rectangular array, a top plate, and a base. The guide columns are installed between the top plate and the base. A tray is installed on the base, and the top of the tray fits against the bottom of the mold. The tray is used to support the formed coal gangue bricks.

[0010] Preferably, the mold is slidably mounted on the guide post, and a second hydraulic rod is mounted on the base, with the output end of the second hydraulic rod connected to the mold.

[0011] Preferably, the pressing mechanism includes a hydraulic cylinder fixedly installed at the bottom end of the top plate, and a pressing mold adapted to the forming cavity of the mold is fixedly installed at the output end of the hydraulic cylinder.

[0012] The technical effects and advantages of this utility model are as follows: 1. By setting up a high-efficiency filling mechanism with a material distribution plate and a hopper, the number of hoppers and mold forming cavities are equal and correspond one-to-one. With the leveling and finishing of the platen, it can ensure that the amount of raw material filling in each forming cavity is accurate and consistent. This effectively solves the problem of uneven filling in the existing single hopper type filling mechanism, avoids the defects of uneven thickness and large density difference in the formed bricks, and significantly improves the product qualification rate. 2. The high-efficiency filling mechanism uses the first hydraulic rod to drive the material box to move precisely, the cylinder to control the opening and closing of the sealing plate, and the third hydraulic rod to drive the plate to sort the raw materials. The coordinated action of each component realizes the automated process of receiving, sorting, moving and filling without manual intervention. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figures 1-4 The high-efficiency molding machine for producing coal gangue bricks shown includes a frame 1, a pressing mechanism 2 disposed on the top of the frame 1, a mold 3 disposed in the middle of the frame 1, and a high-efficiency filling mechanism 4; wherein: The high-efficiency filling mechanism 4 is used to achieve precise and uniform filling of the forming cavity of the mold 3. It includes a material box 401 with openings at both the top and bottom. The material box 401 is located below the material drop port of the feeding conveyor belt to facilitate the receipt of coal gangue raw materials conveyed by the feeding conveyor belt. The material box 401 is equipped with a distribution plate 402. The distribution plate 402 is equipped with a number of material bins 403. The number of material bins 403 is equal to the number of forming cavities of the mold 3, and the position of the material bins 403 corresponds one-to-one with the position of the forming cavity. This ensures that the raw material in each material bin 403 can be accurately filled into the corresponding forming cavity, ensuring uniform filling. The bottom end of the material bin 403 is flush with the bottom end of the distribution plate 402, so that the raw material in the material bin 403 can fall smoothly into the forming cavity and avoid material residue blockage.

[0020] A third hydraulic rod 404 is installed on the material distribution plate 402. A flat plate 405 is fixedly installed on the output end of the third hydraulic rod 404. The bottom end of the flat plate 405 is in contact with the top end of the material distribution plate 402. The third hydraulic rod 404 is used to drive the flat plate 405 to move horizontally back and forth on the material distribution plate 402. When the third hydraulic rod 404 drives the flat plate 405 to move, it can scrape and sort the raw materials in each hopper 403 to ensure that the raw material filling amount in each hopper 403 is consistent, further improving the uniformity of filling, and at the same time avoiding the raw material from piling up too high and affecting the subsequent material discharge.

[0021] A side frame 406 is provided on one side of the frame 1, providing a sliding support base for the material box 401. The material box 401 is slidably mounted on the side frame 406, and can slide horizontally on the side frame 406, realizing the switching of the material box 401 between the feeding station and the filling station. A cylinder 407 is installed on one side of the material box 401, and a sealing plate 408 is fixedly installed on the output end of the cylinder 407. The top of the sealing plate 408 is in contact with the bottom of the material box 401. The cylinder 407 can drive the sealing plate 408 to move, thereby opening and closing the bottom opening of the material box 401. When the material box 401 receives raw materials, the sealing plate 408 is closed to prevent the raw materials from leaking out. When filling, the sealing plate 408 is opened to allow the raw materials to fall. A first hydraulic rod 409 is installed on the side frame 406. The output end of the first hydraulic rod 409 is connected to the material box 401. The first hydraulic rod 409 provides power for the horizontal sliding of the material box 401, ensuring that the material box 401 moves smoothly and accurately.

[0022] The frame 1 is used to carry and support the various components of the equipment. It includes four guide columns 101 arranged in a rectangular array, a top plate 102, and a base 103. The guide columns 101 are installed between the top plate 102 and the base 103 to form a stable frame structure. A tray 5 is installed on the base 103. The top of the tray 5 is attached to the bottom of the mold 3. The tray 5 is used to carry the formed coal gangue bricks, which facilitates the uniform carrying and transportation of the formed bricks, reduces the intensity of manual labor, and ensures the continuity of production.

[0023] The mold 3 is slidably mounted on the guide post 101. The guide post 101 guides and limits the movement of the mold 3, ensuring that the mold 3 moves up and down smoothly and accurately. A second hydraulic rod 6 is installed on the base 103. The output end of the second hydraulic rod 6 is connected to the mold 3. The second hydraulic rod 6 can drive the mold 3 to move up and down along the guide post 101, realizing the lifting and adjustment of the mold 3 to meet the needs of the filling and pressing processes.

[0024] The pressing mechanism 2 is used to pressurize and form the raw material in the forming cavity of the mold 3. It includes a hydraulic cylinder 201 fixedly installed at the bottom of the top plate 102. The output end of the hydraulic cylinder 201 is fixedly installed with a pressing mold 202 that is adapted to the forming cavity of the mold 3. The hydraulic cylinder 201 drives the pressing mold 202 to move up and down. When the pressing mold 202 moves down, it can be accurately embedded in the forming cavity to apply pressure to the raw material and complete the forming.

[0025] Working principle: When the feeding conveyor belt is started, the coal gangue raw material falls into the material box 401 through the discharge port. Under the action of the distribution plate 402, the raw material enters each material bin 403. When the raw material in the material bin 403 is filled to the preset height, the feeding conveyor belt stops feeding and the third hydraulic rod 404 is started. The third hydraulic rod 404 drives the leveling plate 405 to move horizontally back and forth along the top of the distribution plate 402 to scrape and arrange the raw material in each material bin 403 to ensure that the amount of raw material in each material bin 403 is consistent. After the arrangement is completed, the third hydraulic rod 404 drives the leveling plate 405 to return to the initial position.

[0026] Start the first hydraulic rod 409, which drives the material box 401 to slide horizontally along the slide rail on the side frame 406 until each material bin 403 on the material box 401 is precisely aligned with each forming cavity on the mold 3 (at this time, the material box 401 reaches the filling station).

[0027] The cylinder 407 is activated, and its retraction causes the sealing plate 408 to move, opening the bottom opening of the material box 401. The sorted coal gangue raw material in the hopper 403 falls precisely into the corresponding forming cavity of the mold 3 under the action of gravity, completing the filling. After the filling is completed, the cylinder 407 extends, causing the sealing plate 408 to reset and close the bottom opening of the material box 401. At the same time, the first hydraulic rod 409 drives the material box 401 to reset to the feeding position, ready to receive the next batch of raw materials.

[0028] The second hydraulic rod 6 is activated, and the second hydraulic rod 6 extends to drive the mold 3 to move upward along the guide column 101 until the mold 3 reaches the preset pressing position; the hydraulic cylinder 201 of the pressing mechanism 2 is activated, and the hydraulic cylinder 201 extends to drive the pressing mold 202 to move downward. The pressing mold 202 is precisely embedded in the forming cavity, applying a preset pressure to the raw material and maintaining the pressure for a preset time to complete the pressing and forming of the coal gangue brick.

[0029] After pressing is completed, the hydraulic cylinder 201 retracts, driving the pressing mold 202 to move upward and reset; the second hydraulic rod 6 retracts, driving the mold 3 to move downward and reset along the guide column 101, and the formed coal gangue bricks fall onto the tray 5 on the base 103; the operator or subsequent transfer equipment transfers the formed bricks on the tray 5 to complete the entire production cycle, and the equipment enters the next round of work.
