Description

Technical Field

[0001] This utility model relates to the field of metal colored stone tile production technology, specifically a pressure stabilization system for high-viscosity adhesives used in the production of metal colored stone tiles. Background Technology

[0002] Metallic stone tiles, as a new type of high-end roofing material, have been increasingly widely used in the construction field in recent years. In their production process, the uniform spraying of high-viscosity adhesive is one of the key steps to ensure product quality and appearance. Existing technology CN217774651U discloses an integrated adhesive supply system suitable for metallic stone tiles, including an outdoor storage tank adhesive module and a base adhesive recovery valve group, as well as an indoor adhesive pump group and a spraying chamber; the storage tank adhesive module is connected to the adhesive pump group, the adhesive pump group is connected to the spraying chamber, and the base adhesive recovery valve group connects the storage tank adhesive module and the spraying chamber. Although the structure in the above-mentioned existing technology can effectively reduce equipment costs, centralized adhesive supply can stabilize spraying pressure and ensure uniform spraying. However, in actual production, due to workshop layout, production line design, or process requirements, there is often a long distance (greater than 30m) between the pressure supply source of the adhesive and the spraying terminal performing the spraying operation. During the long-distance pipeline transportation of the adhesive, the flow resistance increases significantly, easily causing pressure loss and periodic pressure pulsation. This pressure instability can cause fluctuations in the adhesive flow rate and atomization effect at the adhesive spraying terminal outlet, which may in turn affect the uniformity and adhesion of the adhesive on the substrate. Simply increasing the power of the adhesive pump to compensate for pressure loss is sometimes insufficient to effectively smooth out these dynamic pressure fluctuations and may lead to excessive energy consumption. Utility Model Content

[0003] The present invention aims to solve the above problems, thereby providing a pressure stabilizing system for high-viscosity adhesives used in the production of metal colored stone tiles that ensures that the outlet pressure is always maintained within a stable range.

[0004] The technical solution adopted by this utility model to solve the aforementioned problem is: A pressure stabilizing system for high-viscosity adhesives used in the production of metallic colored stone tiles includes a pressure supply source, a delivery pipeline, and a spraying terminal. The pressure supply source is connected to the spraying terminal via the delivery pipeline. A pressure buffer mechanism is connected in parallel to the delivery pipeline. The pressure buffer mechanism includes a hydraulic cylinder and a bladder-type accumulator. A piston is installed inside the cylinder, which divides the inside of the cylinder into an adhesive chamber and a hydraulic oil chamber. The delivery pipeline is connected to the adhesive chamber, and the bladder-type accumulator is connected to the hydraulic oil chamber.

[0005] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are: By installing a pressure buffer mechanism consisting of a hydraulic cylinder and a bladder-type accumulator in parallel on the delivery pipeline, the displacement of the piston can be used to absorb or compensate for pressure fluctuations caused by long-distance delivery in real time, and the pressure energy can be stored and released through the bladder-type accumulator, thereby playing a role in smoothing the pipeline pressure and helping to improve the stability of the outlet pressure of the glue spraying terminal.

[0006] As a preferred embodiment, a further technical solution of this utility model is: Furthermore, the buffer mechanism also includes a multi-way valve. The inlet of the multi-way valve is connected to the delivery pipeline, the first outlet of the multi-way valve is connected to the glue spraying terminal, and the second outlet of the multi-way valve is connected to the adhesive chamber of the hydraulic cylinder. By setting the multi-way valve, the adhesive can be diverted at the end of the delivery pipeline. Part of it flows to the glue spraying terminal for normal spraying, while the other part can flow into or out of the adhesive chamber of the hydraulic cylinder according to the pressure, providing a structural basis for pressure regulation.

[0007] Furthermore, the multi-way valve is a four-way valve, with its third outlet serving as a backup or pressure relief interface. In addition to meeting basic flow diversion requirements, the four-way valve's additional interface can be used as a backup path to connect a manual spray gun to meet flexible touch-up needs, or to provide a pressure relief channel when the system pressure is abnormal, increasing the flexibility and safety of system applications.

[0008] Furthermore, the pressure buffer mechanism also includes a three-way valve. The first port of the three-way valve is connected to the hydraulic oil chamber of the hydraulic cylinder, the second port is connected to the bladder accumulator, and the third port serves as the hydraulic oil injection port. The three-way valve facilitates the connection between the hydraulic oil chamber and the bladder accumulator, forming a complete hydraulic pressure stabilization circuit. At the same time, its oil injection port function provides convenience for the replenishment and maintenance of the system's hydraulic oil.

[0009] Furthermore, the conveying pipeline includes rigid pipe sections for long-distance conveying and flexible hose sections for equipment interface connections. The combination of rigid pipe sections and flexible hose sections ensures the reliability of long-distance conveying and absorbs some vibration through flexible connections, adapting to the needs of equipment layout.

[0010] Furthermore, the pressurized supply source includes a pressurized glue tank and a pump station for supplying pressure to the glue tank. This configuration provides initial delivery power for high-viscosity adhesives and is the pressure source for stable system operation.

[0011] Furthermore, the bladder-type energy storage device includes a housing, inside which a rubber bladder is disposed. An inflation valve communicating with the rubber bladder is provided at the top of the housing, and an inlet / outlet liquid valve is provided at the bottom of the housing. The rubber bladder is pre-filled with inert gas, and a liquid filling chamber is formed between the bladder and the housing. This structure enables the bladder-type energy storage device to efficiently store and release hydraulic energy through the compression and expansion of the rubber bladder. Its pre-filled gas provides adjustable back pressure, thereby achieving rapid response to pressure fluctuations and energy buffering. Attached Figure Description

Detailed Implementation

[0013] The present invention will be further described below with reference to embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0014] A pressure stabilizing system for high-viscosity adhesives used in the production of metallic colored stone tiles includes a pressurized supply source, a delivery pipeline 8, and a spraying terminal 5. The pressurized supply source is connected to the spraying terminal 5 through the delivery pipeline 8. A pressure buffer mechanism is connected in parallel on the delivery pipeline 8. The pressure buffer mechanism includes a hydraulic cylinder 6 and a bladder-type accumulator 7. A piston is installed inside the cylinder of the hydraulic cylinder 6, which divides the inside of the cylinder into an adhesive chamber and a hydraulic oil chamber. The delivery pipeline 8 is connected to the adhesive chamber, and the bladder-type accumulator 7 is connected to the hydraulic oil chamber.

[0015] Furthermore, the buffer mechanism also includes a multi-way valve. The inlet of the multi-way valve is connected to the delivery pipe 8, and the first outlet of the multi-way valve is connected to the glue spraying terminal 5. A delivery pipe 8 is also provided between the first outlet of the multi-way valve and the glue spraying terminal 5. The second outlet of the multi-way valve is connected to the adhesive chamber of the hydraulic cylinder 6. By setting the multi-way valve, the adhesive can be diverted at the end of the delivery pipe 8. Part of it flows to the glue spraying terminal 5 for normal spraying, while the other part can flow into or out of the adhesive chamber of the hydraulic cylinder 6 according to the pressure, providing a structural basis for pressure regulation.

[0016] Furthermore, the multi-way valve is a four-way valve 3, with its third outlet serving as a backup or pressure relief interface. In addition to meeting basic flow diversion requirements, the four-way valve 3's additional interface can serve as a backup path to connect a manual spray gun to meet flexible touch-up needs, or provide a pressure relief channel when the system pressure is abnormal, increasing the flexibility and safety of system applications.

[0017] Furthermore, the pressure buffer mechanism also includes a three-way valve 4. The first port of the three-way valve 4 is connected to the hydraulic oil chamber of the hydraulic cylinder 6, the second port is connected to the bladder accumulator 7, and the third port serves as the hydraulic oil injection port. The three-way valve 4 facilitates the connection between the hydraulic oil chamber and the bladder accumulator 7, forming a complete hydraulic pressure stabilization circuit. At the same time, its oil injection port function provides convenience for the replenishment and maintenance of the system's hydraulic oil.

[0018] Furthermore, the conveying pipeline 8 includes a rigid pipe section for long-distance conveying and a flexible hose section for equipment interface connection. The combination of rigid pipe section and flexible hose section ensures the reliability of long-distance conveying and absorbs some vibration through flexible connection, adapting to the needs of equipment layout.

[0019] Furthermore, the pressurized supply source includes a pressurized glue tank 1 and a pump station 2 for providing pressure to the glue tank 1. This configuration provides initial delivery power for high-viscosity adhesives and is the pressure source for stable system operation.

[0020] Furthermore, the bladder-type energy storage device 7 includes a housing 71, a rubber bladder 72 disposed inside the housing 71, an inflation valve 73 communicating with the rubber bladder 72 at the top of the housing 71, and an inlet / outlet liquid valve 74 at the bottom of the housing 71. The rubber bladder 72 is pre-filled with inert gas, and a liquid filling chamber 75 is formed between the bladder and the housing 71. This structure enables the bladder-type energy storage device 7 to efficiently store and release hydraulic energy through the compression and expansion of the rubber bladder 72. The pre-filled gas provides adjustable back pressure, thereby achieving rapid response to pressure fluctuations and energy buffering.

[0021] In the production process of metal colored stone tiles, the pressurized supply source, including the pressurized adhesive tank 1 and the pump station 2, provides the power for conveying the high-viscosity adhesive. The adhesive is conveyed over a long distance through the conveying pipeline 8, which includes rigid pipe sections and flexible hose sections. When the adhesive is conveyed to the end of the pipeline, it enters through the inlet of the multi-way valve in the pressure buffer mechanism, flows to the spraying terminal 5 through the first outlet of the multi-way valve for normal spraying, and is simultaneously connected to the adhesive chamber of the hydraulic cylinder 6 through the second outlet of the multi-way valve. When the pressure in the conveying pipeline 8 pulsates due to long-distance conveying, if the pressure is too high, the excess adhesive pushes the piston in the hydraulic cylinder 6 to move towards the hydraulic oil chamber. The compressed hydraulic oil enters through the first port of the three-way valve 4, and then flows through the three-way valve... The second interface of 4 flows to the bladder-type energy storage device 7; if the pressure is too low, the hydraulic oil in the bladder-type energy storage device 7 flows back to the hydraulic oil chamber through the three-way valve 4, driving the piston to move towards the adhesive chamber and replenishing the adhesive in the pipeline; the hydraulic oil in the filling chamber 75 formed between the bladder and the shell 71 flows through the inlet and outlet valves 74 at the bottom of the shell 71 through the compression and expansion of the rubber bladder 72 pre-filled with inert gas in the bladder-type energy storage device 7, quickly absorbing or releasing pressure energy; this process, through the linkage of the piston, compensates for the pressure loss in the delivery pipeline 8 in real time or absorbs the pressure peak, thereby effectively suppressing the pressure fluctuation caused by long-distance delivery and ensuring that the adhesive pressure at the outlet of the glue spraying terminal 5 remains stable.

[0022] The above description is only a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
