[0001] The invention belongs to the technical field of hollow brick processing, in particular to a pressing and forming device for producing hollow gangue bricks. Background Art

[0002] Gangue is a solid waste discharged during the coal mining and coal washing process. It is a kind of black-gray rock with low carbon content and harder than coal that accompanies the coal seam during the coal formation process. After the gangue is crushed, it can be used as the raw material of hollow bricks to make gangue hollow bricks. During the processing of gangue hollow bricks, it needs to be pressed and formed, but it is inconvenient to unload, which affects the overall efficiency.

[0003] After searching, the Chinese patent document (application publication number CN113664956A) discloses a hollow brick production forming device, including a base, a support member is arranged on one side of the top of the base, a driving member is arranged between the support member and the base, and four limit mechanisms for accommodating hollow brick raw materials are arranged equidistantly on the support member. The present invention can extrude the hollow brick raw materials in a limit mechanism into hollow bricks under the action of the first pressing plate and the mold core of the molding mechanism through the molding mechanism set up. Through the driving member, the support member can drive the limit mechanism to rotate, and the limit mechanism with the hollow brick rotates to the bottom of the second pressing plate of the molding mechanism. Through the shifting mechanism, the limit mechanism with the hollow brick is opened. Under the action of the molding mechanism, when the hollow brick in another limit mechanism is squeezed, the formed hollow brick is moved to the conveying device, which not only realizes automatic demoulding and saves labor costs, but also realizes multiple stations and improves the production efficiency of hollow bricks. When processing coal gangue hollow bricks, they need to be pressed and formed, but it is inconvenient to unload, which affects the overall efficiency. Summary of the invention

However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0039] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0040] See also Figures 1 to 10 , this embodiment includes:

[0041] A connecting block 1, both sides of which are rotatably connected to support plates 2;

[0042] The counterweight plate 3 is arranged below the connecting block 1. A power linear motor 4 is installed on the top of the counterweight plate 3. A vertical support plate 5 is welded to the top of the moving part of the power linear motor 4. The vertical support plate 5 is welded and fixed to the connecting block 1. The power linear motor 4 drives the moving part to move, and then drives the connecting block 1 to move, so that another empty support plate 2 is located below the outer mold 11, and unloading and pressing are carried out simultaneously to improve the overall efficiency.

[0043] A plurality of auxiliary plates 6 are welded to the top of the counterweight plate 3, and a lifting lug 7 is welded to the top of the auxiliary plate 6. The lifting lug 7 is rotatably connected to a plurality of transverse pulleys 8 arranged side by side for supporting the support plate 2 through a rotating shaft. The inclined pulley 10 and the plurality of transverse pulleys 8 can support the support plate 2, improve the stability of the support plate 2 during pressing, ensure the safety during pressing, and when unloading is required, the transverse pulley 8 does not affect the unloading process;

[0044] Both sides of the vertical support plate 5 are embedded with tilting electric push rods 9, and the moving part of the tilting electric push rods 9 is connected with a tilting pulley 10 for supporting the support plate 2. The tilting pulley 10 is arranged below the support plate 2. The contraction of the tilting electric push rods 9 is controlled to make the tilting pulley 10 move obliquely downward, and the support plate 2 rotates into a tilted state with gravity, and then the hollow coal gangue bricks are taken away manually or mechanically;

[0045] An inverted U-shaped connecting plate 12 is welded to the top of the counterweight plate 3, and a first electric push rod 13, two second electric push rods 14 and two third electric push rods 15 are embedded in the bottom end of the connecting plate 12.

When the support plate 2 is in the positive position of the outer mold 11, the inner mold 16 is adapted to the outer mold 11. When the outer mold 11 and the inner mold 16 are in the downward position, the third electric push rod 15 and the first electric push rod 13 are extended, so that the outer mold 11 and the inner mold 16 are pressed against the support plate 2, and the external equipment introduces the coal gangue hollow brick raw material into the gap between the outer mold 11 and the inner mold 16. After the introduction is completed, the second electric push rod 14 is controlled to extend, so that the pressing and forming plate 17 moves downward, and then the coal gangue hollow brick is pressed and formed. After forming, the third electric push rod 15 and the first electric push rod 13 are pre-contracted. Due to the limitation of the pressing and forming plate 17, the outer mold 11 and the inner mold 16 are demoulded. After the demoulding is completed, the second electric push rod 14 is controlled to shrink and reset.

[0046] In order to clean the support plate 2, two transverse linear motors 18 are installed at the top of the two support plates 2, and the tops of the moving parts of the two transverse linear motors 18 are connected to L-shaped assembly plates 19, and the sides of the two assembly plates 19 are installed with assembly electric push rods 20. The bottom ends of the moving parts of the two assembly electric push rods 20 are connected to connecting rods 21, and the outer periphery of the connecting rod 21 is sleeved with a sleeve 22, and the bottom end of the sleeve 22 is welded with a connecting circular plate 23, and the bottom ends of the two connecting circular plates 23 are commonly connected to a The scraper 24 of the cleaning support plate 2 is arranged in an inclined state for easy cleaning. A pressure sensor 25 is installed at the bottom end of the connecting rod 21. A spring 26 is connected between the pressure sensor 25 and the connecting circular plate 23. After the unloading is completed, the electric push rod 20 is assembled to extend, driving the connecting rod 21 to move downward, and then the scraper 24 touches the ground and the spring 26 contracts. The transverse linear motor 18 drives the assembly plate 19 and the electric push rod 20 to move, so that the scraper 24 cleans the surface of the support plate 2.

[0047] The two vertical inner walls of the connecting plate 12 are both equipped with a vertical linear motor 27 with a height adjustment function. The side of the moving part of the vertical linear motor 27 is detachably connected with a vertical assembly block 28, and the side of the assembly block 28 is equipped with a camera 29 for recording.

[0048] In order to improve stability, a plurality of slide rails 30 are installed on the top of the counterweight plate 3, and the slide rails 30 are slidably connected with a slider 31. An auxiliary support plate 32 for improving stability is welded between the slider 31 and the connecting block 1. A plurality of circular channels are opened on the top of the counterweight plate 3, and countersunk bolts 33 for installation and fixation are arranged in the circular channels.

[0049] In order to meet the needs of use, the support plate 2, the outer mold 11, the inner mold 16 and the press-molding plate 17 are all constructed as hollow structures, and the inner walls of the support plate 2, the outer mold 11, the inner mold 16 and the press-molding plate 17 are installed with multiple heating wires 34 for heating, and the tops of the support plate 2, the outer mold 11, the inner mold 16 and the press-molding plate 17 are all provided with air permeable channels. The support plate 2, the outer mold 11, the inner mold 16 and the press-molding plate 17 are all constructed of materials that are easy to demold. The slight heating of the heating wire 34 separates the hollow coal gangue bricks from the support plate 2, the outer mold 11, the inner mold 16 and the press-molding plate 17, which is easy to demold.

[0050] The power linear motor 4, the tilt electric push rod 9, the first electric push rod 13, the second electric push rod 14, the third electric push rod 15, the lateral linear motor 18, the assembly electric push rod 20, the pressure sensor 25, the vertical linear motor 27, the camera 29, and the heating wire 34 are all set to the prior art. The working principle, size and model are irrelevant to the function of the present application, so they are not described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0051] How it works

[0052] In the press-forming device for producing hollow gangue bricks, when the support plate 2 is directly below the outer mold 11, the third electric push rod 15 and the first electric push rod 13 are extended so that the outer mold 11 and the inner mold 16 are pressed against the support plate 2, and the external equipment introduces the hollow gangue brick raw material into the gap between the outer mold 11 and the inner mold 16. After the introduction is completed, the second electric push rod 14 is controlled to extend so that the pressing and forming plate 17 moves downward, thereby pressing and forming the hollow gangue brick. After forming, the third electric push rod 15 and the first electric push rod 13 are pre-contracted. Due to the limit of the pressing and forming plate 17, the outer mold 11 and the inner mold 16 are demoulded. After the demoulding is completed, the second electric push rod 14 is controlled to extend so that the pressing and forming plate 17 moves downward, thereby pressing and forming the hollow gangue brick. After forming, the third electric push rod 15 and the first electric push rod 13 are pre-contracted. Due to the limit of the pressing and forming plate 17, the demoulding of the outer mold 11 and the inner mold 16 is realized. After the demoulding is completed, the second electric push rod 14 is controlled to extend so that the pressing and forming plate 17 moves downward, thereby pressing and forming the hollow gangue brick. The electric push rod 14 retracts and resets, and then the power linear motor 4 drives the moving part to move, and then drives the connecting block 1 to move, so that the other empty support plate 2 is under the outer mold 11, and the contraction of the tilting electric push rod 9 is controlled to make the tilting pulley 10 move obliquely downward, and the support plate 2 rotates to an inclined state with gravity, and then the hollow coal gangue bricks are removed manually or mechanically. After the unloading is completed, the assembly electric push rod 20 is extended to drive the connecting rod 21 to move downward, and then the scraper 24 touches the ground and the spring 26 contracts. The transverse linear motor 18 drives the assembly plate 19 and the assembly electric push rod 20 to move, so that the scraper 24 cleans the surface of the support plate 2.
