Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1 to 6, a panel pressing device for an acoustic screen according to an embodiment of the present invention includes a base 1, a mounting frame 2, a driving mechanism 3, and a pressing head 4; the mounting frame 2 is arranged on the base 1, and a mounting space is formed between the mounting frame 2 and the base 1; the driving mechanism 3 is positioned in the mounting space, and the driving mechanism 3 is arranged on the mounting frame 2; the pressing head 4 is connected with the driving mechanism 3 and driven by the driving mechanism 3 to be close to or far away from the base 1, and the end part of the pressing head 4 is provided with an embossing 41.

When the sound screen board 10 is manufactured, concrete is poured into the mold 20, the mold 20 preliminarily compacts the concrete to form the panel 101 of the sound screen board 10, then the mold 20 is conveyed to the base 1, the pressing head 4 presses the panel 101 downwards, in the pressing process, the embossing 41 penetrates into the panel 101, the panel 101 is pressed to form the grains 1011, then the mold 20 is conveyed to another station, sound-absorbing cotton is placed in the mold 20, then the concrete is poured into the mold 20, the mold 20 compacts the concrete to form the back layer 102, the grains 1011 are formed by pressing the panel 101, the contact area between the back layer 102 and the panel 101 is increased, and the combination between the back layer 102 and the panel 101 is firmer. Therefore, the utility model discloses can make the faying face pressure of sound screen 10 panel 101 into the line 1011 of being convenient for, line 1011 is convenient for firmly be connected with sound screen 10 back layer 102.

Optionally, the mounting frame 2 is fixed on the base 1 by a connecting column 5. As shown in fig. 1 and 2, the number of the connecting columns 5 in this example is four, the connecting columns are respectively fixed at four corners of the base 1, one end of each connecting column 5 is connected with the base 1, the other end of each connecting column 5 is connected with the mounting frame 2, and the connecting columns 5 can be provided with adjusting devices to adjust the distance between the base 1 and the mounting frame 2, so that the height of the pressing head 4 can be adjusted, the pressing density of the panel 101 can be conveniently adjusted, or the acoustic screen panel 10 can be suitable for different types (different heights).

In this example, actuating mechanism 3 is the press, and the press sets up to two, and two presses are evenly set up on mounting bracket 2, and a pressure head 4 is connected to two presses to improve stability. The press is a short for press, hydraulic press and oil press, the press is a molding machine for molding industrial products by pressure, and the pressing is the prior art and is not described herein. By providing a press, the distance of descent of the ram 4 can be controlled to compact the panel 101.

In this example, the press is connected to the ram 4 by a connecting block 6. Connecting block 6 one side is fixed on the press promptly, and pressure head 4 is fixed at connecting block 6 opposite side for can change different pressure heads 4, and different pressure heads 4 correspond different impressed watermark 41, thereby be convenient for select different impressed watermark 41 according to the demand, with the suppression different line 1011. In order to facilitate the accurate insertion of the ram 4 into the die 20 for pressing, the side of the connecting block 6 is provided with a guide insert rod 61 which is inserted into the connecting hole 201 of the die 20. The terminal surface of direction inserted bar 61 is the direction cambered surface, and when the suppression, the direction cambered surface of direction inserted bar 61 inserts along the connecting hole 201 inside wall to it is more accurate when making the suppression.

In some examples, the pressing head 4 includes a body 42 and a plurality of side pressing blocks 43 and a plurality of center pressing blocks 44 fixed on the side of the body 42, the embossing 41 is formed on the end of the side pressing blocks 43 and the center pressing blocks 44, the body 42 may be rectangular, the side pressing blocks 43 are four and fixed on the four sides of the body 42, the center pressing blocks 44 may be two, and the two center pressing blocks 44 are fixed on the bottom of the body 42 in a cross shape, so that the grain 1011 on the whole bottom of the panel 101 is shaped like a Chinese character tian, so that the panel 101 is firmly combined with the back layer 102, in this example, the embossing 41 protrudes from the body 42, so that the embossing 41 is deep into the concrete during pressing, and the grain 1011 is formed on the panel 101.

As an example, the emboss 41 is waved, so that the grain 1011 formed on the panel 101 is also waved, thereby making the contact area between the back layer 102 and the panel 101 large when the back layer 102 of the sound screen panel 10 is manufactured, increasing the firmness of the combination of the back layer 102 and the panel 101, and making the whole body firmer, of course, the emboss 41 in this example may be zigzag, and the principle is the same.

In some examples, a plurality of through holes 421 are provided in the body 42, and in the mold 20, the tip pins 202 are generally provided, and after placing concrete in the mold 20, the concrete covers the lower portions of the tip pins 202 and does not cover the upper portions of the tip pins 202, and the tip pins 202 allow the sound-absorbing holes 103 to be formed in the demolded sound panel 10. In this example, a plurality of through holes 421 are provided in the body 42, and when the panel 101 is pressed, the upper portion of the sharp pin 202 is inserted into the through holes 421, so that the panel 101 forms the grain 1011.
