Description

Technical Field

[0001] This utility model relates to the field of grouting device technology, and more specifically, to a layered grouting device for pulp molding. Background Technology

[0002] A layered injection device for pulp molding refers to a specialized piece of equipment used in the pulp molding process to inject pulp suspension into the molding die in layers and stages. This device controls the injection timing, flow rate, pressure and distribution of different pulps to form a multi-layered structure with different densities, thicknesses, materials or functional characteristics in the mold.

[0003] However, the grouting position of the layered grouting device for pulp molding is fixed and inconvenient to adjust, making it difficult to adapt to the grouting requirements of molds of different sizes or shapes. This results in uneven grouting or incomplete coverage, affecting product consistency. Furthermore, after grouting is completed, pulp residue is easily left in the grouting area of ​​the layered grouting device for pulp molding. If not cleaned in time, it will dry and clog the nozzle, affecting the accuracy of subsequent grouting and even causing equipment failure.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0024] Example 1:

[0027] Example 2:

[0028] like Figures 1-2 , Figure 3 As shown, according to an embodiment of the present invention, a layered grouting device for pulp molding is provided with an auxiliary mechanism 3 on the support frame 207 and the grouting nozzle 205. The auxiliary mechanism 3 includes an electric guide rail 301 provided below the support frame 207 via a moving block, which is used to move the grouting nozzle 205 according to the layered grouting situation, which is beneficial to improve the uniformity of grouting. A control valve 302 is connected to the grouting nozzle 205. One end of the control valve 302 is connected to a cleaning hose 303, which is used to deliver high-pressure cleaning fluid, which is beneficial to cleaning the inside of the grouting nozzle 205 and preventing the grouting nozzle 205 from clogging. One end of the cleaning hose 303 is connected to a delivery pump 304, which is used to deliver high-pressure cleaning fluid.

[0029] One end of the delivery pump 304 is connected to a water pipe 305 for delivering the cleaning fluid stored in the water storage box 306. The other end of the water pipe 305 is connected to the water storage box 306 for storing the cleaning fluid. A replenishment hole or delivery pipe (not shown in the figure) is provided on the top of the water storage box 306 during actual use for replenishing the cleaning fluid. A processing table 4 is connected to the side of the water storage box 306 and the bottom of the electric guide rail 301. A molding mold 5 is provided on the processing table 4 for assisting subsequent molding. A collection box (not shown in the figure) is provided on the processing table 4 during actual use. The collection box or molding mold 5 can be used to assist in collecting and cleaning pulp during actual use.

[0030] The delivery pump 304, control valve 2 302, electric guide rail 301, electric telescopic rod 2 7, electric telescopic rod 1 208, and metering pump 203 are electrically connected to a controller (not shown in the figure) in actual use. The controller is a PLC (programmable logic controller) or a microcontroller. The specific working control program of the controller is written and set according to the actual situation, which is conducive to the precise control of the electrically connected electrical components. The above structure is electrically connected to an external power supply in actual use.

[0031] The transfer pump 304, control valve 2 302, electric guide rail 301, electric telescopic rod 2 7, electric telescopic rod 1 208, and metering pump 203 are existing technologies and will not be described in detail. The specific model and specifications need to be selected and determined according to the actual specifications of the device.

[0032] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0033] In summary, with the help of the above-mentioned technical solution of this utility model, during operation, the sealing cover 9 above the layered grouting cylinder 1 is opened first, and pulp raw materials are added into the cylinder through the placement port. The thick pulp and the thin pulp are stored in the thick pulp chamber and the thin pulp chamber, which are divided by the partition plate 6, respectively. After the material is added, the sealing cover 9 is locked with the lock 10 to ensure the airtightness during storage. In order to prevent the pulp from settling during long-term storage, the electric telescopic rod 7 is started and drives the mixing plate 8 to reciprocate inside the thick pulp chamber and the thin pulp chamber to continuously stir the pulp to maintain its uniform suspension state.

[0034] During the grouting stage, according to the layered structure requirements of the molded product, the control valve 201 is opened, the delivery pipe 202 connected to it is opened, and the metering pump 203 is started to draw pulp of a specified concentration from the layered grouting cylinder 1. It is then delivered to the grouting nozzle 205 through the output hose 204. The grouting nozzle 205 accurately sprays the pulp into the molding mold 5 located on the processing table 4 to achieve the deposition of the first layer of slurry. During this process, the electric guide rail 301 can drive the support frame 207 and the grouting nozzle 205 installed on it to move in the horizontal direction through the moving block, thereby expanding the grouting coverage area and improving the grouting uniformity.

[0035] When it is necessary to adjust the grouting thickness or coverage angle, the electric telescopic rod 208 pushes the adjustment plate 206 to move up and down on the support frame 207, thereby changing the spraying height and angle of the grouting nozzle 205. This allows for flexible grouting in accordance with different mold contours. After completing one layer of grouting, the control valve 201 on the other side can be switched to extract grout of different concentrations from another chamber for the next layer of grouting, thus achieving precise molding of multi-layer structures.

[0036] After the grouting process is completed, in order to prevent residual grout from clogging the grouting nozzle 205, the system automatically enters the cleaning mode. Control valve 302 and delivery pump 304 are opened. Delivery pump 304 draws clean water from water storage box 306 and sends it into the grouting nozzle 205 through water pipe 305 and cleaning hose 303 to form a high-pressure flushing water flow to remove residual grout. The wastewater and residual pulp after flushing can fall directly into the collection box on the processing table 4 for subsequent centralized treatment or fall into the molding mold 5. This not only wets the molding mold 5 but also allows the residual pulp to be reused.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
