[0002] Refractory bricks are refractory materials made by firing refractory clay or other refractory raw materials. They have certain shapes and sizes. According to the preparation process, they can be divided into fired bricks, unfired bricks, fused bricks, and refractory insulation bricks. According to the shape and size, they can be divided into standard bricks, ordinary bricks, special bricks, etc. Refractory bricks need to be extruded by molds during the production and processing.

[0003] The existing Chinese patent CN114536513A discloses an extrusion molding device for refractory brick processing, which uses an electric hydraulic rod to press the pressing plate downward to compact the raw materials. During the extrusion process, the excess raw materials overflow the mold and then fall into the collection box through the net, which can prevent the raw materials from contaminating the panel and recycle the excess raw materials to avoid waste.

[0004] However, during the use of the above-mentioned device, when the pressing plate is in the process of compacting the raw materials, the overflowed raw materials will not only fall into the collection box through the mesh, but also overflow onto the pressing plate, resulting in the need to clean up the overflowed raw materials on the pressing plate every time the pressing plate compacts the raw materials, which greatly increases the workload of the operator. If the overflowed raw materials on the pressing plate cannot be cleaned up in time, the overflowed raw materials on the pressing plate will dry and solidify, making it more difficult to clean them up.

[0027] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The figure shows an extrusion molding device for refractory brick processing, comprising a base 1, a detachable mold 2 is installed at the center of the upper end of the base 1, support columns 3 are fixedly installed at the four corners of the upper end of the base 1, a top plate 4 is fixedly installed on the upper end of the support column 3, a pressing plate 5 is installed on the lower side of the top plate 4, an electric push rod 9 is fixedly installed at the four corners of the pressing plate 5 at the lower end of the top plate 4, and the lower end of the electric push rod 9 is fixedly connected to the pressing plate 5, the upper end of the base 1 is located at the lower side of the mold 2 and a leakage net 12 is fixedly embedded therein, a material receiving hopper 11 that can move forward and backward is movably installed inside the base 1, two symmetrically distributed supporting cross bars 10 are fixedly installed on the four supporting columns 3, a scraping structure 8 is installed on the supporting cross bars 10 and located on the lower side of the pressing plate 5; a cleaning structure 6, which is used to clean the raw materials overflowing from the upper end surface of the pressing plate 5, is installed on the upper side of the pressing plate 5.

[0028] See also Figure 3 The cleaning structure 6 includes a sleeve 601 installed at the center of the upper end of the pressure plate 5. The outer side of the sleeve 601 is fixedly sleeved with a first bearing 606 at its lower end, and the sleeve 601 is rotatably connected to the pressure plate 5 through the first bearing 606. The cross-sectional shape of the sleeve 601 is annular, and a cylindrical block 602 is fixedly embedded at the upper end of the sleeve 601.

[0029] See also Figure 2 and Figure 6 A first motor 603 is fixedly installed at the center of the upper end of the top plate 4, and the driving end of the first motor 603 is fixedly connected to a connecting rod 604 through a coupling, and the connection between the connecting rod 604 and the top plate 4 is a rotational connection, and four circumferentially equidistantly distributed limit strips 605 are fixedly arranged on the outer side of the connecting rod 604, and the limit strip 605 and the connecting rod 604 are an integrated structure.

[0030] See also Figure 3 The connection between the cylindrical block 602 and the connecting rod 604 and the limit strip 605 is a movable sleeve connection. A first scraper 607 is fixedly installed on the outer side of the sleeve 601, and the lower end of the first scraper 607 is movably fitted with the upper end surface of the pressure plate 5. A baffle 608 is fixedly sleeved on the outer side of the first scraper 607, and the lower end surface of the baffle 608 is movably fitted with the upper end surface of the pressure plate 5.

[0031] The working principle of cleaning the raw materials overflowing from the pressing plate is as follows: after the pressing plate 5 moves down to compact the raw materials in the mold 2, the electric push rod 9 drives the pressing plate 5 to move up. When the pressing plate 5 moves up and leaves the mold 2, the first motor 603 drives the connecting rod 604 to rotate. Under the action of the limiting strip 605 on the outer side of the connecting rod 604, the rotation of the connecting rod 604 can drive the sleeve 601 and the first scraper 607 to rotate together. Since the lower end of the first scraper 607 is movably fitted with the upper end surface of the pressing plate 5, the first The scraper 607 can loosen the raw materials overflowing on the pressing plate 5 during the rotation process, and can drive the loosened raw materials to move on the pressing plate 5 during the rotation process of the first scraper 607. Most of the raw materials will fall directly from the pressing plate 5 during the rotation process of the first scraper 607, which can prevent the raw materials from drying and condensing on the pressing plate 5. The initial position of the first scraper 607 is located on the diagonal line of the pressing plate 5. When the pressing plate 5 stops moving upward, the first scraper 607 can reset to its original position after rotating several circles.

[0032] Example 2: Please refer to Figure 4This embodiment further explains Example 1. A blowing assembly 7 is installed on the outer side of the sleeve 601. The blowing assembly 7 includes a rubber piston 701 that is movably embedded in the sleeve 601 and can move up and down in the sleeve 601, and the lower end of the connecting rod 604 is fixedly embedded in the rubber piston 701. The outer wall of the rubber piston 701 is movably fitted with the inner wall of the sleeve 601, and a plurality of groups of air inlet pipes 702 that are equidistantly distributed are fixedly embedded on the outer side of the sleeve 601.

[0033] See also Figure 3 The air inlet pipe 702 is interconnected with the sleeve 601, and two symmetrically distributed air blowing pipes 703 are installed on the outer side of the first scraper 607 on the sleeve 601. The connection between the air blowing pipe 703 and the sleeve 601 is a fixed connection, and the air blowing pipe 703 and the sleeve 601 are interconnected. The air blowing pipe 703 passes through the baffle 608, and the connection between the air blowing pipe 703 and the baffle 608 is a fixed connection.

[0034] See also Figure 5 A hollow ball 704 is movably installed inside the air inlet pipe 702 and the air blowing pipe 703. The outside of the hollow ball 704 is located at the inside of the air inlet pipe 702 and the air blowing pipe 703, and a rubber ring 705 and a perforated plate 706 are respectively provided. The rubber ring 705 installed inside the air inlet pipe 702 is fixedly embedded in one end of the air inlet pipe 702 located outside the sleeve 601, and the perforated plate 706 installed inside the air blowing pipe 703 is fixedly embedded in one end of the air blowing pipe 703 located outside the sleeve 601.

[0035] In this embodiment, when the pressure plate 5 moves upward and the first motor 603 drives the first scraper 607 to rotate, the cylindrical block 602 is movably connected with the connecting rod 604 and the limit bar 605. Therefore, when the height of the connecting rod 604 remains unchanged and the position of the sleeve 601 moves upward, the rubber piston 701 moves downward inside the sleeve 601. Since the outer wall of the rubber piston 701 is movably fitted with the inside of the sleeve 601, the rubber piston 701 can move the sleeve 601 downward during the downward movement. 01 is squeezed, and the hollow ball 704 inside the air inlet pipe 702 will press against the rubber ring 705, and the hollow ball 704 inside the air blowing pipe 703 will stay away from the rubber ring 705, so the gas inside the sleeve 601 will be blown out through the hole plate 706 in the air blowing pipe 703, and when the first scraper 607 rotates to loosen the raw materials, the air blowing from the air blowing pipe 703 can blow the loosened raw materials off the pressing plate 5, which is beneficial to clean up the raw materials overflowing from the pressing plate 5.

[0036] Example 3: Please refer to Figure 7, this embodiment further explains other embodiments, the scraping structure 8 includes a second scraper 801 whose upper end can be movably fitted with the lower end surface of the pressing plate 5, the front end of the second scraper 801 is fixedly connected to the first connecting seat 802, the rear end of the second scraper 801 is fixedly connected to the second connecting seat 803, the interior of the second connecting seat 803 is penetrated by a reciprocating screw 804, the interior of the first connecting seat 802 is penetrated by a sliding rod 805, and the connection method between the sliding rod 805 and the supporting cross bar 10 is a fixed connection, one end of the reciprocating screw 804 is fixedly connected to the second motor 806, and the second motor 806 is fixedly installed on the supporting cross bar 10 through a fixing plate, the outer side of the reciprocating screw 804 is fixedly sleeved with two symmetrically distributed second bearings 807, and the reciprocating screw 804 is rotatably connected to the supporting cross bar 10 through the second bearing 807.

[0037] In this embodiment: when the electric push rod 9 drives the pressing plate 5 to move up to the specified position, the second motor 806 runs to drive the reciprocating screw 804 to rotate. Under the condition that the reciprocating screw 804 is threadedly connected to the second connecting seat 803 and the first connecting seat 802 is slidingly connected to the sliding rod 805, the rotation of the reciprocating screw 804 can drive the second connecting seat 803 and the second scraper 801 to move back and forth left and right at the lower end of the pressing plate 5. Since the second scraper 801 is movably fitted with the lower end surface of the pressing plate 5, the second scraper 801 can automatically scrape off the raw materials attached to the lower end of the pressing plate 5 during the movement, and can clean the pressing plate 5.
