Description

Technical Field

[0001] This utility model relates to the field of ceramic production technology, specifically to a ceramic blank adhesion adjustment device. Background Technology

[0002] The production process of ceramic products typically involves multiple steps, including raw material mixing, clay forming, drying, and firing. Among these, the raw material mixing stage plays a crucial role in the quality of the ceramic products. To enhance the plasticity and forming strength of ceramic clay, it is often necessary to add an appropriate amount of adhesive (such as CMC, PVA, etc.) to the clay to improve its adhesion and forming stability.

[0003] Currently, in the preparation of ceramic blanks, the addition of adhesive liquid mostly relies on manual quantitative addition or simple mechanical spraying, followed by mixing using stirring equipment. This method has many uncertainties in practical applications, such as unstable adhesive liquid addition, uneven spraying, and unsatisfactory mixing effects, which seriously affect the batch consistency of ceramic products and the final yield.

[0004] Existing mud mixing equipment has the following shortcomings:

[0005] The adhesive supply method is crude: the adhesive is mostly introduced into the mixing system by gravity flow or simple pumping, lacking quantitative control, which makes it difficult to accurately control the amount of adhesive used, thus affecting the adhesion of the raw material and the molding quality.

[0006] The spraying structure is simple but the coverage is uneven: some devices use fixed nozzles or single-point glue injection, which limits the spraying range and makes it difficult to achieve full coverage of the mud surface. This results in poor fusion between the adhesive and the mud, affecting the uniformity of mixing.

[0007] The mixing and spraying processes are not synchronized: the mixing mechanism and the adhesive spraying control do not form a closed-loop logic, making it impossible to dynamically adjust the addition of adhesive according to the real-time mixing status, and making it difficult to adapt to the differentiated needs of different types or batches of mud.

[0008] Lack or inaccurate control system: Most devices are not equipped with an automated control system, which makes it impossible to dynamically adjust the glue pumping volume and spraying frequency according to process parameters, making it difficult to meet the needs of refined and automated production.

[0009] Therefore, there is an urgent need for a ceramic blank adhesion adjustment device with a reasonable structure, precise control, and uniform spraying, which can realize the precise delivery and dynamic spraying control of the adhesive liquid, thereby improving the uniformity and stability of the blank mixing and enhancing the overall quality of ceramic products. Summary of the Invention

[0010] This invention aims to overcome the technical problems in existing ceramic blank mixing processes, such as uneven addition of adhesive liquid, poor accuracy in adjusting adhesion, and limited spraying range. It provides a ceramic blank adhesion adjustment device that can achieve quantitative delivery, uniform spraying, and efficient mixing of adhesive liquid, thereby achieving precise adjustment of ceramic clay adhesion and improving the consistency and molding quality of the blank.

[0011] To achieve the above objectives, this utility model provides a ceramic blank adhesion adjustment device, comprising: a mixing box, a reduction drive unit, a spraying assembly, and a control pump unit.

[0012] in:

[0013] The mixing box is equipped with an openable top cover and a feeding compartment door, and has a rotatable stirring shaft inside.

[0014] The speed reduction drive unit is installed outside the mixing box and is used to drive the stirring shaft to rotate;

[0015] The spraying assembly includes an inlet pipe, a distribution pipe, and multiple spray nozzles. The spray nozzles are installed below the distribution pipe to achieve full coverage spraying of the mud surface.

[0016] The control pump set includes a drive motor, a cross shaft bracket, a drive gear set, a driven gear, and two pump sets;

[0017] The pump unit includes a fixed vortex tube, a helical shaft, and a transmission gear disc, wherein:

[0018] The fixed spiral tube is a closed cylindrical structure with a single spiral channel inside; the spiral shaft is located inside the fixed spiral tube and forms a screw pump structure with it, with the shaft center eccentrically arranged relative to the transmission gear plate; when the spiral shaft rotates, it spirally pushes the adhesive liquid to achieve stable and uniform liquid supply;

[0019] The drive motor drives the drive gear set to rotate through the worm gear, which in turn drives the two transmission gear discs to rotate in opposite directions, driving the two pump sets to work alternately.

[0020] The input terminal of the drive motor is electrically connected to the automatic control system, which precisely adjusts the delivery amount of adhesive liquid according to the set parameters.

[0021] The beneficial effects achieved by this utility model are as follows:

[0022] 1. Quantitative adhesive supply: The eccentric screw pump structure enables stable pumping of high-viscosity adhesive liquid, effectively controlling the amount sprayed each time and ensuring the accuracy of adhesion adjustment.

[0023] 2. Uniform spraying: The multi-spray vortex structure combined with the distribution pipe arrangement enables all-round spraying of the mud, improving the bonding effect between the adhesive and the mud.

[0024] 3. High-efficiency mixing: The stirring shaft rotates continuously under the drive of the reduction gear unit and operates synchronously with the spraying, effectively improving the mixing speed and uniformity of the adhesive liquid and mud.

[0025] 4. Intelligent control: The pump unit is driven by an automatic control system, which realizes automated operation and precise adjustment of adhesive amount, improves work efficiency and reduces manual dependence.

[0026] In summary, this utility model has a novel structure, high functional integration, and high adjustment precision, and has broad engineering application prospects. It is particularly suitable for the adhesion adjustment process of clay before molding in ceramic production. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other. It should be understood that the described embodiments are only for illustrating the technical solutions of this utility model and are not intended to limit its scope of protection.

[0038] like Figures 1 to 6 As shown, this utility model discloses a ceramic blank adhesion adjustment device, including a mixing box 100, a reduction drive unit 200, a spraying assembly 300 and a control pump unit 400.

[0039] The mixing box 100 is a hollow shell structure, mainly used to contain and mix mud. A top cover 110 is provided on the top surface, and a feeding door 111 is provided on the top cover 110 to facilitate the addition of mud or adhesive liquid into the box.

[0040] The speed reduction drive unit 200 is installed on the outside of the mixing box 100. Its output shaft passes through the box and is connected to the stirring shaft 210 located inside the box. It is used to drive the stirring shaft to rotate, so as to fully stir and mix the mud and adjust its viscosity.

[0041] The spray assembly 300 includes an inlet pipe 310, a distribution pipe 320, and several spray nozzles 330. One end of the inlet pipe 310 is connected to the control pump unit 400, and the other end is connected to the distribution pipe 320. The distribution pipe 320 is located inside the mixing tank 100 at the top, and multiple spray nozzles 330 are installed on its bottom surface. These nozzles 330 are evenly arranged to spray the adhesive liquid onto the surface of the mud in the mixing tank, achieving full-coverage spraying. Specifically, the spray nozzles 330 are evenly distributed below the distribution pipe 320 to spray the adhesive liquid onto the surface of the mud in the mixing tank 100, achieving full-coverage spraying.

[0042] The control pump set 400 is used to realize the delivery and quantitative control of the adhesive liquid. It includes a drive motor 410, a cross shaft 420, a drive gear set 430, a driven gear 421, and two pump sets 440.

[0043] The drive motor 410 is fixedly installed inside the top cover 110, and its output end is provided with a worm gear 411. The worm gear 411 meshes with the drive gear set 430 to drive its rotation. The drive gear set 430 and the driven gear 421 arranged opposite to it mesh with the transmission gear discs 443 of the two pump sets respectively, forming a pair of mutually driving rotational systems.

[0044] Each pump unit 440 includes a fixed-rotation tube 441, a helical shaft 442, and a transmission gear disc 443. The fixed-rotation tube 441 is a closed cylindrical structure with an axially extending single helical channel inside. The helical shaft 442 is disposed within this helical channel, and its axis is eccentrically positioned relative to the transmission gear disc 443. Specifically, both ends of the fixed-rotation tube 441 are connected to the ends of the inlet pipe 310 and the distribution pipe 320, respectively, and the axis of the helical shaft 442 is offset from the axis of the transmission gear disc 443.

[0045] During operation, the transmission gear 443 rotates due to the synchronous meshing of the driving gear set 430 and the driven gear 421, causing the helical shaft 442 to rotate eccentrically within the fixed-rotation tube 441. Since the fixed-rotation tube and the helical shaft form a screw pump structure, the adhesive liquid is continuously pumped to the outlet end under the guidance and compression of the helical structure, achieving stable and uniform liquid supply.

[0046] The viscous liquid enters the pump unit through the inlet pipe 310, and is propelled in a spiral direction by the helical shaft 442 within the fixed-rotation tube 441. Finally, it is delivered to the spray head 330 via the distribution pipe 320, thus being evenly sprayed onto the surface of the mud in the mixing tank 100. Specifically, the helical shaft 442 is made of an elastic material or a wear-resistant composite material to accommodate the continuous delivery of high-viscosity viscous liquid and extend the service life of the device.

[0047] The automatic control system is electrically connected to the drive motor 410, enabling intelligent adjustment of its operating status and thus precise control of the adhesive liquid supply. By controlling the rotation speed and operating time, the liquid volume of each spray can be effectively adjusted to ensure uniform adhesion of the mud.

[0048] In addition, to adapt to the conveying conditions of high-viscosity viscous liquids, the screw shaft 442 can be made of composite materials with elasticity or wear resistance, such as rubber-coated steel core, stainless steel-polyurethane composite rod, etc., to improve pumping efficiency and extend the service life of the device.

[0049] This invention achieves precise adjustment of the adhesion of ceramic blanks during the mixing process through a combination of "control pump group + screw pump structure + automatic control". It is particularly suitable for the pretreatment process before ceramic raw materials are formed, and has the advantages of compact structure, uniform spraying and high control precision.
