[0001] The invention relates to the technical field of sintered composite wallboard plastering, and more particularly to a precise metering device for the plastering process of sintered composite wallboard. Background Art

[0002] During the production of sintered composite wall panels, they need to be plastered. Plastering is to mix powder (adhesive) with water. The existing metering methods mostly use electronic belt scales to measure the powder and then distribute water.

[0003] (1) Due to different usage scenarios and requirements, the belt is affected by various factors during operation, and the speed of the belt is not stable, which will cause measurement errors.

[0004] (2) Factors such as belt tension and temperature will affect the measurement accuracy of the belt scale and increase the relative error.

[0005] (3) When the material is applied to the belt, the distribution range is relatively large as the conveying flow rate changes, and it changes with its humidity and belt speed, which also has a certain impact on the measurement accuracy.

[0006] Therefore, the shortcomings of electronic belt scale applications mainly focus on the fact that the measurement accuracy is not high enough or not stable enough. Summary of the Invention

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0032] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

For example, they may refer to a fixed connection, an indirect connection via an intermediate medium, internal communication between two components, or an interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0035] In addition, the terms "comprises" and "having" and any variations thereof are intended to cover a non-exclusive inclusion, for example, a process, method, system, product or display that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, product or display.

[0036] The following will be combined Figure 1-5 , a precise metering device for the sintered composite wall panel plastering process involved in the embodiment of the present application is described in detail. It is worth noting that the following embodiments are only used to explain the present application and do not constitute a limitation of the present application.

[0037] A precise metering device for the plastering process of sintered composite wall panels may include: a powder metering mechanism, a liquid metering mechanism, a mixer, and a transmission mechanism. The powder metering mechanism is used to quantitatively weigh powder; the liquid metering mechanism is used to quantitatively weigh liquid; the mixer is used to mix powder and liquid, and the mixer is located below the liquid metering mechanism. The quantitatively weighed liquid directly enters the mixer by gravity; the transmission mechanism is arranged between the powder metering mechanism and the mixer, and is used to transmit the quantitatively weighed powder to the mixer.

[0038] The powder metering mechanism provided in the embodiments of the present application is different from traditional electronic belt scales. By using the powder metering mechanism provided in the present application, quantitative measurement of adhesive can be achieved, and by using the liquid metering mechanism, quantitative measurement of water can be achieved. This allows for precise weighing of adhesive and water, facilitating improved mixing accuracy. This reduces the mixing error of the specialized adhesive and ensures stable bonding performance.

[0039] The powder metering mechanism includes: a first conveyor belt, a hopper, and a lifting plate. The first conveyor belt is a commonly used conveying device in the prior art. The first conveyor belt can be mounted on a driving roller and a driven roller. The driving roller is driven by a stepper motor. The lifting plate is arranged below the first conveyor belt to support the first conveyor belt. The hopper is placed above the first conveyor belt via a bracket. The bottom opening of the hopper is opposite to the lifting plate, so that the bottom opening of the hopper contacts the first conveyor belt to achieve dynamic sealing. This can avoid the situation where the first conveyor belt and the bottom opening of the hopper are poorly sealed due to changes in the tension of the first conveyor belt.

[0040] The lifting plate can be fixed by a bracket or directly movable. The movable setting means that the height of the lifting plate can be slightly adjusted to ensure that the bottom of the hopper and the first conveyor belt always maintain a dynamic seal.

[0041] The dynamic sealing between the hopper and the first conveyor belt is solved, and the problem of quantitative feeding is solved. The hopper includes a hopper body and a distribution bin arranged below the hopper body. The bottom of the distribution bin is open, and the top of the distribution bin is a sliding distribution unit. The hopper body and the distribution bin can be connected or isolated through the sliding distribution unit. The side wall of the distribution bin on the side facing the output end of the first conveyor belt is a sliding blocking unit. The sliding blocking unit can allow the material in the distribution bin to be transported to the mixer along with the first conveyor belt.

[0042] After the distributing unit is pulled out, the adhesive in the hopper body falls into the distributing bin at the bottom, filling the distributing bin. Then the distributing unit is pushed in to isolate the hopper body and the distributing bin. In this way, the distributing bin is filled with material which is the preset amount of adhesive. Due to the dynamic seal maintained by the first conveyor belt at the bottom of the powder bin, when the blocking unit is opened, the material in the distributing bin will be transported away by the first conveyor belt, realizing the transportation after quantitative weighing of the adhesive.

[0043] In order to ensure that the powder in the hopper body can fill the sub-bin, the hopper body is in the shape of an inverted pyramid or inverted prism with a larger top and a smaller bottom. In this way, the powder at the bottom is under greater pressure, making it easier to fill the sub-bin.

[0044] In some embodiments, the material distribution unit includes a distribution plate and a distribution cylinder. The distribution plate is slidably disposed in a chute provided on the side wall of the hopper body or the distribution bin, and the distribution cylinder is disposed on a material rack. The distribution plate is controlled by the distribution cylinder, and the distribution plate is guided and limited by the chute. Of course, in order to better ensure the smooth operation of the distribution plate, guide chute can also be provided on both sides of the hopper body or the distribution bin, so that the distribution plate can operate more smoothly.

[0045] In some embodiments, the material blocking unit includes a material blocking plate and a material blocking cylinder. The material blocking plate is slidably disposed in a guide groove formed on the side wall of the sub-bin, and the material blocking cylinder is disposed on a material rack. The material blocking cylinder can control the material blocking plate to slide or retract in the guide groove to open or close the material outlet of the sub-bin.

[0046] In some embodiments, the input end of the conveyor mechanism is disposed below the output end of the first conveyor belt. A powder scraper is provided below the output end of the first conveyor belt for scraping powder adhering to the first conveyor belt into the conveyor mechanism. The powder scraper ensures that the powder, i.e., the adhesive, conveyed by the first conveyor belt is transferred to the conveyor mechanism as completely as possible. The conveyor mechanism may be a roller conveyor belt. Alternatively, a powder scraper may be provided at the output end of the roller conveyor belt to facilitate scraping as much of the material as possible into the mixer via the powder scraper.

[0047] In some embodiments, the powder metering mechanism further includes a screw-type powder conveyor for conveying powder into the hopper. The powder conveying device utilizes a screw conveyor to drive the powder forward, and a cover is located on the top of the conveying conduit to prevent dust from being generated during the conveying process. The hopper also has a cover on top, which can be made of plexiglass to facilitate observation of the hopper's contents.

[0048] In some embodiments, the liquid metering mechanism includes a water tank, a water inlet unit, a water outlet unit and a water level controller. The water tank is set on the mixer through a support frame, the water inlet unit is set on one side of the water tank, the water outlet unit is set at the bottom of the water tank, and the water level controller is used to control the water inlet amount of the water tank.

[0049] The water inlet unit includes a water inlet pipe and a first electromagnetic water valve. The water inlet pipe is arranged on the upper side wall of the water tank, and the first electromagnetic water valve is arranged on the water inlet pipe. The control unit is a float valve connected to the first electromagnetic water valve. The water outlet unit includes a water outlet pipe and a second electromagnetic water valve. The water outlet pipe is arranged on the bottom wall of the water tank, and the second electromagnetic water valve is arranged on the water outlet pipe.

[0050] Before mixing, the first solenoid valve on the water inlet is open. When the water level in the water tank reaches the set point, the float valve controls the water replenishment. During material distribution at the front end, the first solenoid valve on the water inlet is closed. While the adhesive powder is being transported from the distribution silo, the second solenoid valve on the water outlet is opened to mix the water and adhesive powder. Once the volume-fixed mixing is complete, the second solenoid valve on the water outlet is closed, and the first solenoid valve on the water inlet is opened to replenish the water tank.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
