Description

Technical Field

[0001] This utility model relates to the field of material conveying system technology, and in particular to an adhesive conveying system with a backup pipeline. Background Technology

[0002] Traditional adhesive conveying systems typically consist of a storage tank and a conveying device, with the conveying device primarily transporting the adhesive from the storage tank to a designated location via a single pipeline. However, in actual production, the screw mechanism within the conveying device may be damaged due to prolonged operation, mechanical wear, material impurities, and other factors. Once the screw mechanism malfunctions, the entire conveying system will cease to function properly, leading to production interruptions and consequently impacting production efficiency and product quality. Utility Model Content

[0003] To address the problem that a screw mechanism malfunction can prevent the entire material conveying system from functioning properly during actual production, this invention provides an adhesive conveying system with a backup pipeline.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] An embodiment of this utility model provides an adhesive delivery system with a backup pipeline, comprising:

[0006] Storage tanks;

[0007] A conveying device is connected to the storage tank. The conveying device includes a main pipeline, a backup pipeline, and a conveying pipeline. The inlets of the main pipeline and the backup pipeline are both connected to the storage tank, and the outlets of the main pipeline and the backup pipeline are both connected to the conveying pipeline. The main pipeline is equipped with a screw mechanism for conveying adhesive, and the backup pipeline is equipped with a control valve for controlling its on / off state. The conveying pipeline is arranged vertically and has a first outlet and a second outlet, the height of which is greater than the height of the first outlet.

[0008] According to some embodiments of this utility model, both the first outlet and the second outlet are provided with switching valves.

[0009] According to some embodiments of this utility model, the control valve is a ball valve.

[0010] According to some embodiments of the present invention, the main pipeline is further provided with a drive device for driving the screw mechanism.

[0011] According to some embodiments of the present invention, a filter device for filtering adhesive impurities is further provided between the storage tank and the conveying device.

[0012] According to some embodiments of the present invention, the filtration device includes a first filter box and a second filter box, and both the first filter box and the second filter box are provided with a filtration structure.

[0013] According to some embodiments of the present invention, the filtration structure includes a filter barrel, and the filter barrel is provided with a plurality of filter holes.

[0014] According to some embodiments of the present invention, the filter structure further includes a support frame at the bottom of the filter barrel.

[0015] This invention has at least the following beneficial effects: By setting up a backup pipeline, when the screw mechanism of the main pipeline fails, it can quickly switch to the backup pipeline, allowing the adhesive delivery to continue, effectively avoiding production stoppages caused by equipment failure and ensuring production continuity. Simultaneously, the backup pipeline of this invention has a first outlet and a second outlet at different heights. When switching to the backup pipeline, the pressure provided by the storage tank alone may not be sufficient to deliver the adhesive to the higher second outlet. By setting a lower first outlet, it can be ensured that the adhesive can still be delivered smoothly even under insufficient pressure. Attached Figure Description

[0021] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0022] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0024] Embodiments of this utility model provide an adhesive delivery system with backup piping, such as... Figure 1-5 As shown, it includes:

[0025] Storage tank 100;

[0026] The conveying device 200 is connected to the storage tank 100. The conveying device 200 includes a main pipeline 210, a backup pipeline 220, and a conveying pipeline 230. The inlets of the main pipeline 210 and the backup pipeline 220 are both connected to the storage tank 100, and the outlets of the main pipeline 210 and the backup pipeline 220 are both connected to the conveying pipeline 230. The main pipeline 210 is provided with a screw mechanism 211 for conveying adhesive, and the backup pipeline 220 is provided with a control valve 221 for controlling its on / off state. The conveying pipeline 230 is arranged vertically and has a first outlet 231 and a second outlet 232. The height of the second outlet 232 is greater than the height of the first outlet 231.

[0027] The storage tank 100 stores the adhesive and serves as the raw material supply for the entire conveying system. The conveying device 200 is connected to the storage tank 100 and includes a main pipeline 210, a backup pipeline 220, and a conveying pipeline 230. The main pipeline 210 is the primary conveying channel and incorporates a screw mechanism 211 for conveying the adhesive. The backup pipeline 220 serves as a backup conveying channel. Due to the height of the storage tank 100, the material inside has significant pressure. It is activated when the main pipeline 210 malfunctions, utilizing the pressure within the storage tank 100 to convey the adhesive. The conveying pipeline 230 connects the outlets of the main pipeline 210 and the backup pipeline 220, delivering the adhesive to the final point of use. A control valve 221 is installed within the backup pipeline 220 to control its on / off state. By setting up a backup pipeline 220, when the main pipeline 210 fails, the system can quickly switch to the backup pipeline 220, reducing production downtime caused by equipment failure. This downtime allows for the procurement of a new screw mechanism for replacement, improving system reliability. When the screw mechanism 211 needs to be replaced, the valve of the storage tank 100 can be closed first to suspend the supply of material to the main pipeline 210 and the backup pipeline 220 before replacement. In some embodiments, on / off valves are provided on both sides of the screw mechanism 211. By setting these valves, the screw mechanism 220 can be replaced while maintaining the supply of material to the backup pipeline 220, further reducing the impact of screw mechanism 211 damage on production. In some space-constrained production environments, setting the material delivery pipeline 230 vertically can better adapt to the equipment layout and avoid pipeline crossings or conflicts with other equipment. When switching to the backup pipeline 220, the pressure provided by the storage tank 100 alone may not be sufficient to deliver the adhesive to the higher second outlet 232. By setting the first outlet 231 at a lower height, the adhesive can be smoothly delivered even under insufficient pressure, ensuring production continuity. By providing two outlets at different heights, the system can select the appropriate outlet for delivery based on actual pressure conditions, improving the system's flexibility and adaptability.

[0028] The working principle of this utility model is as follows:

[0029] Normal operating condition: Under normal circumstances, the adhesive is conveyed through the screw mechanism 211 of the main pipeline 210. At this time, the control valve 221 of the backup pipeline 220 is closed, and the backup pipeline 220 does not participate in the material conveying.

[0030] Troubleshooting: When the screw mechanism 211 in the main pipeline 210 is damaged or malfunctions, the control valve 221 of the backup pipeline 220 can be opened to utilize the pressure of the storage tank 100 to deliver the adhesive. This allows the adhesive to enter the conveying pipeline 230 through the backup pipeline 220, ensuring smooth production and preventing production interruptions due to equipment failure. If the pressure provided by the storage tank 100 is insufficient to deliver the adhesive to the second outlet 232, the process can be switched to the first outlet 231.

[0031] In some embodiments, a switching valve 240 is provided at both the first outlet 231 and the second outlet 232.

[0032] The opening and closing of the first outlet 231 and the second outlet 232 can be controlled by the switching valve 240 to adapt to the normal working state or switch to the state of the standby pipeline 220.

[0033] In some embodiments, the control valve 221 is a ball valve.

[0034] The core component of a ball valve is a ball with a through-hole; rotating the ball controls the flow of fluid. This structure is simple and compact, facilitating manufacturing and maintenance. Ball valves are typically operated via a handle or actuator; a simple 90-degree rotation switches the valve from fully open to fully closed, making operation quick and easy.

[0035] In some embodiments, the main pipeline 210 is further provided with a drive device for driving the screw mechanism 211.

[0036] The drive unit provides rotational power to the screw mechanism, enabling the screw to push the adhesive from the storage tank to the delivery line. The drive unit can be driven by an electric motor, whose speed can be adjusted by a gearbox to achieve precise speed control.

[0037] In some embodiments, a filter device 300 for filtering adhesive impurities is also provided between the storage tank 100 and the conveying device 200.

[0038] During production, storage, or transportation, adhesives may become contaminated with impurities such as particles, fibers, and dust. The filter device 300 effectively removes these impurities, ensuring the purity of the conveyed adhesive. Impurities may cause wear or blockage to the conveying device 200 (such as the screw mechanism 211, valves, etc.), affecting the normal operation of the equipment. The filter device 300 reduces damage to the conveying device 200 caused by impurities, extending the service life of the equipment.

[0039] Furthermore, the filtration device 300 includes a first filter box 310 and a second filter box 320, both of which are equipped with filtration structures.

[0040] When one filter box needs cleaning or filter element replacement, the other filter box can continue operating, ensuring continuous system operation and reducing downtime. Two filter boxes can share the filtration workload, extending the lifespan of individual filter elements and reducing maintenance costs. Each filter box can be controlled independently, allowing for the selection of one or both boxes based on process requirements, thus improving system flexibility.

[0041] Each filter box can be equipped with filters or filter cartridges of different precision.

[0042] Furthermore, the filtration structure includes a filter barrel 330, which has a plurality of filter holes 340.

[0043] By setting multiple filter holes 340 on the filter cartridge 330, multi-layer filtration can be achieved, effectively removing impurities from the adhesive and improving filtration accuracy. The filter holes 340 are distributed on the surface of the filter cartridge 330, allowing the adhesive to pass through evenly, reducing local pressure drop and improving filtration efficiency. The filter cartridge 330 can be designed as a detachable structure, facilitating cleaning and replacement of clogged parts of the filter holes 340, reducing maintenance time and costs.

[0044] Furthermore, the filter structure also includes a support frame at the bottom of the filter canister 330.
