DETAILED DESCRIPTION

[0036] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0037] First embodiment

[0038] like Figure 1-Figure 12 As shown, the production device of the imitation stone curbstone of the first embodiment of the utility model comprises:

[0039] A paper supply assembly 1, the paper supply assembly 1 is used for conveying filter paper 2;

[0040] The cutting assembly 3 is used to form at least two strip-shaped openings 21 which are adjacent to each other end by end on the filter paper 2 during the transmission process of the filter paper 2, and each strip-shaped opening 21 and the adjacent extension section of the strip-shaped opening 21 enclose a closed-loop separation portion 22;

[0041] The mold assembly 4 includes a mold shell 41 disposed below the transmission path of the filter paper 2 and having an open top, a bottom mold plate 42 sealedly connected to the circumferential inner wall of the mold shell 41, and a lifting unit 43 for driving the bottom mold plate 42 to rise and fall;

[0042] The filter press assembly 5 includes a hollow filter press shell 51 located just above the bottom template 42, a vacuum pump 52 connected to the inner cavity of the filter press shell 51, and a pressing unit 53 for driving the filter press shell 51 to rise and fall. The bottom surface of the filter press shell 51 is provided with a filter press hole 5121 connected to its own inner cavity. The top of the movable path of the filter press shell 51 is located above the transmission path of the filter paper 2 to press the separation part 22 toward the mold shell 41. After the mold shell 41, the filter press shell 51 and the bottom template 42 are enclosed to form a mold cavity, the separation part 22 covers the inner wall of the mold cavity.

[0043] When the device is in use, the filter paper 2 is provided by the paper supply component 1 while driving the transmission of the filter paper 2, and a plurality of strip openings 21 are formed on the filter paper 2 by means of the cutting component 3, wherein the plurality of strip openings 21 are all through-hole-shaped and are adjacent to each other end to form a closed-loop structure. Specifically, each strip opening 21 and the extension portion corresponding to the adjacent end of the adjacent strip opening 21 encloses a closed-loop separation portion 22, and the separation portion 22 is in the shape of a cross.

[0044] After the filter paper 2 is cut to form a strip-shaped opening 21, and the strip-shaped opening 21 and the corresponding extended portion are enclosed to form a separation portion 22, the paper supply assembly 1 continues to drive the filter paper 2 to be transported, so that the separation portion 22 on the filter paper 2 moves to between the mold assembly 4 and the filter press assembly 5, and the pressing unit 53 in the filter press assembly 5 drives the filter press shell 51 to descend, and at the same time the vacuum pump 52 is started, so that the filter press shell 51 and the filter press hole 5121 generate a vacuum negative pressure, and after the bottom surface of the filter press shell 51 contacts the separation portion 22 of the filter paper 2, the separation portion 22 is firmly adsorbed, and as the filter press shell 51 descends, the separation portion 22 is driven to separate from the filter paper 2, so that the separation portion 22 is close to the mold shell 41, and finally the separation portion 22 enters the mold shell 41, at this time the separation portion 22 covers the inner bottom wall of the mold shell 41 and contacts the circumferential inner wall portion of the mold shell 41.

[0045] Afterwards, the pressing unit 53 drives the filter press shell 51 to rise and injects production mud into the mold shell 41. The mud acts on the separation part 22, so that the separation part 22 is attached to and covers the inner bottom wall and the circumferential inner wall of the mold shell 41, and the separation part 22 partially protrudes from the mold shell 41. The part of the separation part 22 protruding from the mold shell 41 is folded into the mud to make it attached to the top surface of the mud. Then, the pressing unit 53 acts on the filter press shell 51 again, so that the filter press shell 51, the mold shell 41 and the bottom mold plate 42 are enclosed to form a mold cavity, and the separation part 22 covers the inner wall of the mold cavity. Then, the vacuum pump 52 is started to generate negative pressure in the filter press shell 51, and impurities such as air and moisture in the mud are attracted through the filter press holes 5121. These impurities are sucked out through the separation part 22, which is convenient for filtering the mud.

[0046] After the filtration is completed, the pressing unit 53 drives the filter shell 51 to rise, and the lifting unit 43 drives the bottom template 42 to rise, so that the imitation stone curbstone product is separated from the mold shell 41. During the filtration, the separation part 22 covers the inner wall of the mold cavity, so that the mud is isolated from the inner wall of the mold, and it is convenient to filter the air moisture in the mud. In this way, the mud is prevented from sticking to the inner wall of the mold, which is convenient for demoulding and avoids damage to the mold during the demoulding process; in addition, during the production process, the device automatically provides filter paper 2 through the paper supply component 1, and cuts the filter paper 2 through the cutting component 3 to form the separation part 22. When the filtration is convenient, the separation part 22 can cover the inside of the mold cavity, thereby reducing the burden on the staff, and there is no need to manually lay the filter paper 2, thereby reducing labor costs and helping to improve production efficiency.

[0053] A further improvement is that an adsorption through hole 421 is provided on the bottom template 42 , and the adsorption through hole 421 is connected to a negative pressure pump 44 .

[0056] After adopting the above structure, in the filter press assembly 5, the vacuum pump 52 generates a vacuum negative pressure by controlling the filter press shell 51, and after the separation part 22 is sucked and pressed toward the mold shell 41, the negative pressure pump 44 is started, so that a negative pressure is generated in the space between the bottom mold plate 42 inside the mold shell 41 and the separation part 22. At the same time, the vacuum pump 52 stops running, and the separation part 22 is sucked toward the bottom mold plate 42, so that the bottom wall covering part 221 of the separation part 22 is finally attached to and covers the bottom mold plate 42, and at the same time, the side wall covering part 222 covers the circumferential inner wall of the mold shell 41, forming a Fig.12 The structure shown in the middle figure.

[0057] A further improvement is that the output end of the negative pressure pump 44 is connected to a hollow blowing shell 45, and the blowing shell 45 is provided with a blowing port 46 connected to its own inner cavity, and the blowing port 46 is adjacent to the upper side of the opening of the mold shell 41, so that after the bottom wall covering portion 221 of the separation portion 22 is pressed into the mold shell 41 and the mud is injected, the top wall covering portion 223 is blown toward the top surface of the mud; two blowing shells 45 are provided, which are arranged on both sides of the mold shell 41 along the width direction of the mold shell 41.
