Description

Technical Field

[0001] This utility model relates to an adhesive supply system. Background Technology

[0002] In the tube winding process, glue supply is a crucial step that directly affects the quality and performance of the paper tube. The purpose of glue supply is to evenly and appropriately apply glue to the paper, ensuring that the layers of paper are tightly bonded during the winding process. Currently, each production line in the tube winding section has its own glue supply tank, using a single glue pump for supplying glue. These systems are independent and have the following disadvantages: 1. The glue pumps have low power, resulting in low production efficiency, and glue leakage occurs after a period of use; 2. Installing a glue pump on each production line increases energy consumption and production costs, and significantly increases the installation space required for the entire glue supply system in the production area; 3. When the glue is used up, operators need to use a forklift to replace the glue supply tank, causing forklifts to shuttle back and forth on the production site, posing a safety hazard. Utility Model Content

[0003] The purpose of this invention is to solve the problem of high production costs caused by existing glue supply systems that can only supply glue to one production line. The invention proposes a glue supply system that delivers glue drawn in by the glue pump to the glue outlet pipe through the glue delivery pipe. Since the glue delivery pipe is equipped with several glue outlet pipes, it can adapt to the glue supply needs of multiple pipe rolling sections, eliminating the need to install a glue pump on each pipe rolling section, thus greatly reducing energy consumption and operating costs.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a glue supply system, including a glue pump and a glue supply tank, wherein the glue pump includes a glue inlet and a glue outlet, a connecting pipe connected to the glue supply tank is installed on the glue inlet, a glue delivery pipe is installed on the glue outlet, a first control valve is provided on the glue delivery pipe, the glue pump is an internal gear pump, a return pipe connected to the glue supply tank is provided on the glue delivery pipe near the glue outlet, a flow regulating valve is provided on the return pipe, and a plurality of glue outlet pipes are provided at the other end of the glue delivery pipe, each glue outlet pipe being provided with a second control valve and a third control valve.

[0005] Preferably, the first and second control valves are normally open control valves, and the third control valve is a normally closed control valve.

[0006] Preferably, both the glue delivery pipe and the glue supply tank are equipped with a first connector for installing a return pipe.

[0007] Preferably, the other end of the glue delivery tube is provided with a second connector for installing the glue outlet tube.

[0008] Preferably, the glue supply system further includes a support frame, on which both the glue pump and the glue supply tank are mounted.

[0009] Preferably, one end of the bracket is provided with a mounting base for installing a glue pump, and the other end of the bracket is provided with a mounting groove for installing a glue supply tank.

[0010] Preferably, a shock-absorbing pad is provided between the mounting base and the bracket.

[0011] Preferably, the bracket is equipped with a control cabinet connected to the glue pump, and the control cabinet is equipped with a power cord for connecting to 220V AC mains power.

[0012] Preferably, a thermal overload relay is installed inside the control cabinet.

[0013] Preferably, the control cabinet is equipped with a rotary switch and an emergency stop switch.

[0014] In summary, the advantages of this utility model are as follows: The glue pump draws in the glue through the glue delivery pipe and delivers it to the glue outlet pipe. Since the glue delivery pipe has several outlet pipes, it can adapt to the glue supply needs of multiple pipe winding sections, eliminating the need to install a glue pump on each section, thus significantly reducing energy consumption and operating costs. Furthermore, the connection between the glue pump and the glue supply tank via the connecting pipe reduces the number of glue supply tanks used, saving production space and avoiding safety hazards caused by forklifts moving back and forth on the production line. In addition, the second and third control valves allow for independent control of the glue dispensing volume of each outlet pipe, improving the glue dispensing quality. Secondly, by setting the glue pump as an internal gear pump, it gains advantages such as high power, high efficiency, and fast glue extraction, which can significantly improve the efficiency, stability, and applicability of glue delivery, while reducing operating costs and maintenance difficulty. In addition, it can effectively reduce glue leakage. Finally, by installing a return pipe connected to the glue supply tank on the glue delivery pipe, excess glue can be returned to the glue supply tank, thereby achieving flow balance in the glue delivery pipe. This avoids pipe bursts and damage to the glue pump caused by excessive glue in the glue delivery pipe, improving safety performance during use. Furthermore, the return flow rate of glue in the return pipe can be adjusted by a flow regulating valve to adapt to different production needs. Attached Figure Description

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a glue supply system includes a glue pump 1 and a glue supply tank 2. The glue pump 1 includes a glue inlet 11 and a glue outlet 12. A connecting pipe 3 connected to the glue supply tank 2 is installed on the glue inlet 11. A glue delivery pipe 4 is installed on the glue outlet 12. A first control valve 41 is provided on the glue delivery pipe 4. The glue pump 1 is an internal gear pump, specifically an NCB-0.5-W type internal gear pump. A return pipe 5 connected to the glue supply tank 2 is provided on the glue delivery pipe 4 near the glue outlet 12. A flow regulating valve 51 is provided on the return pipe 5. Several glue outlet pipes 6 are provided at the other end of the glue delivery pipe 4. Each glue outlet pipe 6 is provided with a second control valve 61 and a third control valve 62.

[0022] The glue pump draws in the glue through the delivery pipe and delivers it to the outlet pipe. Because the delivery pipe has several outlet pipes, it can accommodate the glue supply needs of multiple pipe winding sections, eliminating the need for a separate glue pump on each section, significantly reducing energy consumption and operating costs. Furthermore, connecting the glue pump to the glue tank via a connecting pipe reduces the number of glue tanks used, saving production space and avoiding safety hazards caused by forklifts moving back and forth on the production line. Additionally, the inclusion of second and third control valves allows for independent control of the glue output from each outlet pipe, improving glue quality. Secondly, the glue pump... The pump is designed with an internal gear, giving it advantages such as high power, high efficiency, and fast glue extraction. This significantly improves the efficiency, stability, and applicability of glue delivery while reducing operating costs and maintenance difficulty. It also effectively reduces glue leakage. Finally, a return pipe connected to the glue supply tank is installed on the glue delivery pipe, allowing excess glue to flow back into the supply tank, thus achieving flow balance in the glue delivery pipe. This avoids pipe bursts and damage to the glue pump caused by excessive glue in the delivery pipe, improving safety during use. In addition, the return flow rate of glue in the return pipe can be adjusted by a flow regulating valve to adapt to different production needs.

[0023] The first control valve 41 and the second control valve 61 are normally open control valves, and the third control valve 62 is a normally closed control valve. Setting the first control valve as a normally open control valve ensures that the glue delivery tube is always open, requiring no additional energy and reducing energy consumption. Setting the second control valve as a normally open control valve and the third control valve as a normally closed control valve effectively prevents glue leakage when the glue delivery tube is not powered or malfunctions, avoiding unnecessary waste and improving glue delivery efficiency.

[0024] Both the glue delivery pipe 4 and the glue supply tank 2 are equipped with a first connector 7 for installing the return pipe 5, which enables the quick installation of the return pipe. In this embodiment, the first connector is provided with an external thread, and the return pipe is provided with a threaded hole connected to the external thread, which simplifies the installation process of the return pipe and the first connector. Moreover, the threaded connection can ensure the stability and reliability of the connection between the glue delivery pipe and the second connector, which is convenient for subsequent inspection and maintenance. The other end of the glue delivery tube 4 is provided with a second connector 42 for installing the glue dispensing tube 6, which enables quick installation of the glue dispensing tube. In this embodiment, the second connector is provided with an external thread, and the glue dispensing tube is provided with a threaded hole connected to the external thread, which simplifies the installation process of the glue dispensing tube and the second connector. Moreover, the threaded connection can ensure the stability and reliability of the connection between the glue dispensing tube and the second connector, which is convenient for subsequent inspection and maintenance. In addition, in order to improve the sealing performance of the first connector and the return tube, as well as the sealing performance of the connection between the second connector and the glue dispensing tube, a sealing ring can be installed on the first connector or the return tube, and the second connector or the glue dispensing tube. The specific installation structure of the sealing ring is existing technology and will not be described in detail in this embodiment. In this embodiment, four second connectors are preferred, which can simultaneously deliver glue to four coiling tube sections.

[0025] The glue supply system also includes a bracket 8, on which both the glue pump 1 and the glue supply tank 2 are mounted. The bracket allows for unified installation of the glue pump and the glue supply tank, reducing the installation space required for the entire glue supply system in the production area. Specifically, one end of the bracket 8 has a mounting base 81 for mounting the glue pump 1, and the other end has a mounting groove 82 for mounting the glue supply tank 2. This allows the glue pump and the glue supply tank to be installed independently on the bracket, facilitating the installation and fixing of connecting pipes. A shock-absorbing pad 83 is provided between the mounting base 81 and the bracket 8. This shock-absorbing pad effectively reduces vibration and noise generated during glue pump operation, extending the service life of the glue pump. The bracket 8 is equipped with a control cabinet 9 connected to the glue pump 1. The control cabinet 9 has a power cord 91 for connecting to 220V AC mains power. The control cabinet is existing technology, and its specific structure will not be described in detail in this embodiment. The control cabinet enables automated control of the glue pump. Mounting the control cabinet on the bracket allows it to form a unified installation unit, further reducing the floor space required and simplifying the installation process. It also reduces the distance between the control cabinet and the glue pump, thereby reducing cable length and wiring costs. The power cord allows for quick power connection to the control cabinet.

[0026] like Figure 3 As shown, a thermal overload relay 92 is installed in the control cabinet 9. When a foreign object gets stuck in the glue pump, the glue pump current increases, the thermal overload relay is activated, the normally closed contact of the thermal overload relay in the circuit opens, the entire circuit is disconnected, the motor loses power and stops running, so as to protect the glue pump motor. The control cabinet 9 is equipped with a rotary switch 93 and an emergency stop switch 94. In this embodiment, each dispensing tube is equipped with a rotary switch and an emergency stop switch. Specifically, rotary switch SA1 and emergency stop switch SE1 correspond to the first dispensing tube, rotary switch SA2 and emergency stop switch SE2 correspond to the second dispensing tube, rotary switch SA3 and emergency stop switch SE3 correspond to the third dispensing tube, and rotary switch SA4 and emergency stop switch SE4 correspond to the fourth dispensing tube. This allows for flexible control of the dispensing volume of the dispensing tubes, enabling the control cabinet to independently control the dispensing tubes without interference between them. The rotary switches allow operators to control the circuit's on / off state by rotating them, enabling precise control of the circuit's operation. In this embodiment, the rotary switches are two-position rotary switches. The emergency stop switch allows operators to press it in case of an emergency where the rotary switch malfunctions. This opens the emergency stop switch, disconnects the control circuit in the control cabinet, and quickly cuts off the power. The glue pump stops operating after losing power, achieving the purpose of emergency shutdown.

[0027] During operation, such as Figure 3As shown, when the main circuit breaker QF is closed, the switching power supply PMS is energized and outputs 24V DC. If the first dispensing tube needs glue supply, turn the glue supply knob switch SA1 to "On". The contactor KM coil is energized, the main contacts close, and the glue pump motor starts running, beginning glue extraction. Simultaneously, the normally open contact of contactor KM closes, and the audible and visual warning light HA is energized, alerting the operator that the glue pump is running. After glue extraction is complete, turn the knob switch SA1 to "Off". The contactor coil KM is de-energized, the main contact coil recovers, and the glue pump motor stops running, stopping glue extraction. Simultaneously, the normally open contact of contactor KM opens, and the audible and visual warning light HA stops working. In case of an emergency where the knob switch SA1 malfunctions, press the emergency stop switch SE1 to disconnect the circuit. The contactor KM coil will be de-energized, the main contacts will recover, and the glue pump motor will stop running.

[0028] In addition to the preferred embodiments described above, there are other embodiments of this utility model. Those skilled in the art can make various changes and modifications based on this utility model. As long as they do not depart from the spirit of this utility model, they should all fall within the scope defined by the appended claims.
