[0002] At present, in the production process of gypsum board, the slurry accumulation height of gypsum board may occasionally be unstable due to various reasons. Among them, the main problem of unstable slurry accumulation height is that the slurry accumulation height is too high, which causes slurry leakage, so that the produced gypsum board has a large amount of slurry on the edge, which becomes a product quality problem.

[0003] In the existing equipment, the slurry injection height is usually detected by infrared detection, so as to adjust the amount of foam in the slurry according to the actual demand, control the slurry output speed, and avoid the overflow or leakage of gypsum board.

[0004] However, in actual use, the slurry injection pipe in the above-mentioned equipment is generally arranged as one, and the pipe is located at the center. The slurry accumulation height fluctuation during the slurry injection process is large, especially when producing relatively wide gypsum board, the required slurry injection amount is large, which further expands the slurry injection thickness fluctuation range, and it is easy to cause the slurry to be too low due to instantaneous accumulation, and the correction is overcorrected, which causes the slurry to be injected too much, and affects the production quality of gypsum board. CONTENT OF THE UTILITY MODEL

[0005] Based on the above description, the utility model provides a molding station slurry control device to solve the problem that in the automatic control structure of the existing gypsum board production equipment, the slurry accumulates at the center, which causes the slurry height to be too large and easily overcorrected, and affects the production quality of gypsum board.

[0008] On the basis of the above technical solutions, the utility model can also be improved as follows.

[0009] Further, the guide plate is hollow inside and has a through hole at the top, the top end of the through hole is connected with the bottom end of the slurry discharge pipe through a connecting flange, and the plurality of spray holes on the bottom surface of the guide plate are in communication with the inside of the guide plate.

[0010] Further, the side wall surface on both sides of the guide plate is further provided with an adjusting member, the adjusting member is an electric telescopic rod, and the output end of the adjusting member extends horizontally into the inside of the guide plate and is provided with a sealing block.

[0011] Further, the inside wall of the guide plate is further provided with a track groove for limiting movement, and the side wall of the sealing block protrudes outward and is movably assembled with the track groove.

[0012] Further, the side wall surface of one end of the sealing block towards the center direction is further provided with an annular sealing ring, and the edge of the annular sealing ring is tightly fitted with the side wall of the guide plate.

[0013] Further, the control assembly comprises a distance measuring sensor arranged on one side of the bottom surface of the mixing machine, the detection end of the distance measuring sensor is arranged vertically downward and just above the center of the cover paper, and a control unit is further mounted on the outside wall of the mixing machine, and the control unit is electrically connected with the distance measuring sensor.

DETAILED DESCRIPTION

[0021] For the purpose of facilitating the understanding of the present application, a more complete description of the present application will be provided below with reference to the relevant drawings. The drawings show embodiments of the present application. However, the present application can be implemented in many different forms, and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0023] Combination Figure 1 And Figure 2 As shown in the figure, a forming station slurry control device comprises:

[0024] The mixer 1 is a stirring device for the production of gypsum board slurry, which is provided with a feed inlet 11 at the top and a slurry discharge pipe 12 at the bottom;

[0025] The foam injection pipe 2 is arranged on one side of the mixer 1 and is in communication with the slurry discharge pipe 12, and is used to inject foaming agent liquid into the slurry, so that it is mixed with the gypsum board slurry. In the production process of the gypsum board, the output of the slurry is controlled mainly by controlling the injection amount of the foaming agent;

[0026] The flow guide plate 3 is arranged at the bottom of the slurry discharge pipe 12, which is hollow inside and is provided with an injection hole 31 at the top. The injection hole 31 can be adjusted according to the width required by the actual production to adapt to the injection range of the slurry, so as to effectively reduce the thick bottom range when the slurry is injected, thereby facilitating the accurate control of the conveying of the gypsum board slurry;

[0027] The conveying platform 4 is arranged with a face paper on its surface, which is arranged just below the flow guide plate 3;

[0028] The control assembly 5 is used to monitor the thickness of the slurry on the face paper in real time, so as to facilitate the adjustment of the injection amount of the foaming agent.

[0029] Specifically, in this embodiment, the flow guide plate 3 should be set as a cuboid structure, and hollow inside, so that the injection holes 31 arranged at the bottom of the flow guide plate 3 can communicate with the inside, and a through hole is also arranged at the top, and a connecting flange is arranged at the edge of the through hole, and the slurry discharge pipe 12 of the mixer 1 is sealingly connected with the connecting flange, so that the gypsum board slurry mixed with the foaming agent is injected into the flow guide plate 3, and is output to the face paper through the multiple injection holes 31 at the bottom.

[0030] At the same time, in order to facilitate observation of the injection amount of the slurry inside the flow guide plate 3, a flow meter 13 should also be arranged at the connection between the flow guide plate 3 and the slurry discharge pipe 12.

[0031] Since the injection points are changed from one to multiple, and the horizontal distance is increased, the slurry will not be concentrated and accumulated at a certain position, so that the fluctuation range of the slurry is further reduced, thereby facilitating the automatic regulation of the control assembly 5 according to the thickness of the slurry, and the quality of the produced gypsum board is more stable.

[0032] Moreover, in actual use, the width of the gypsum board required to be produced is different according to actual needs, and the amount of gypsum slurry required to be injected at a time is also different, especially when injecting the slurry into the relatively wide face paper, the flow guide plate 3 should also be required to further expand the slurry injection range according to actual needs.

[0033] Based on the above requirements, in this embodiment, a sliding rail is also arranged on the inner side wall of the flow guide plate 3, and an adjusting member 32 is arranged on both sides of the flow guide plate 3, the adjusting member 32 is an electric telescopic rod, and the output end thereof extends horizontally into the flow guide plate 3, and a sealing block 33 is fixedly installed at the end of the output end of the adjusting member 32, the side wall of the sealing block 33 is provided with a protrusion and is movably assembled with the sliding rail, and an annular sealing ring 34 is arranged on the side of the sealing block 33 facing the center, and the annular sealing ring 34 is tightly attached to the inner wall of the flow guide plate 3, so that in actual use, the extension and contraction of the electric telescopic rod can effectively control the number of injection holes 31 and the internal space of the flow guide plate 3 for slurry injection, thereby adaptively adjusting according to the width of the face paper used.

[0034] Compared with the existing slurry injection structure, the adjustable structure adopted in this embodiment can greatly reduce the fluctuation range of the slurry thickness caused by the need for a large amount of slurry injection, thereby making the data monitored by the control assembly 5 more accurate, improving the control of the slurry injection amount, and making the gypsum board production more stable.

[0035] The control assembly 5 mainly comprises a distance measuring sensor 51 and a control unit 52, wherein the distance measuring sensor 51 is arranged as a distance measuring device such as an infrared distance meter SW-A40, SW-D70, is fixedly installed on one side of the mixing machine 1, and is arranged vertically downward, so that the detection end thereof is arranged perpendicularly to the surface of the facial tissue; and the control unit 52 is fixedly installed on the outer side wall of the mixing machine 1, can adopt a control structure such as a Siemens G120, TP700, and is internally provided with a PLC single-chip microcomputer for programming control.

[0036] A screw pump 21 should also be arranged at the connection between the foam injection pipe 2 and the slurry discharge pipe 12, and the top inlet of the screw pump 21 is in communication with a storage tank externally storing a foaming agent liquid.

[0037] The distance measuring sensor 51, the screw pump 21 and the electric telescopic rod should all be electrically connected with the control unit 52 through wires, and a staff member can input the width of the facial tissue in advance on the control unit 52, so that the above-mentioned devices can all be automatically adjusted to the corresponding operating state, and the delivery amount of the foaming agent is controlled, thereby realizing automatic production control, so that the production needs not to be repeatedly debugged when being changed, and the use is more convenient.

[0038] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part or all of the technical features thereof; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the present application.
