Description

Technical Field

[0001] The utility model relates to the technical field of glue coating, in particular to a glue supply device. Background Art

[0002] In modern industrial production, gluing processes are crucial for achieving high-quality connections, sealing, and decoration. Their efficiency and quality stability are directly linked to overall product performance and market competitiveness. This is particularly true for certain temperature-sensitive adhesives, whose unique viscosity-temperature inversion characteristics (i.e., viscosity increases with decreasing temperature and decreases with increasing temperature) place even stricter demands on the gluing process.

[0003] The glue supply equipment currently in widespread use generally utilizes a design that combines a feed pump with a delivery pipeline. The pump draws the glue from a storage container and delivers it through a heated delivery pipeline. While this approach can maintain the glue's desired temperature during delivery, thereby controlling its viscosity within the ideal coating range, in practice, the high viscosity of the glue itself forces the pump to overcome significant resistance during the extraction process. This not only increases the pump's energy consumption and wear, but can also affect the efficiency and stability of the glue extraction process.

[0004] Therefore, how to develop a glue supply equipment that can efficiently handle high-viscosity, temperature-sensitive glue, ensure a continuous and uniform glue supply process, and reduce glue extraction resistance and blockage risks has become a technical problem that technicians in this field urgently need to solve.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] Example 1, see Figure 1-Figure 2 The present application provides a glue supply device, including a base 1 for placing a glue barrel; a lifting member 2, which is vertically symmetrically arranged on the base 1, and the telescopic ends of the two lifting members 2 are commonly connected to the support plate 21; a feeding pump 3, which is fixed on the support plate 21, and a pressure plate 4 is provided at the bottom of the feeding pump 3, and the pressure plate 4 is a 5-gallon pressure plate. The pressure plate 4 is used to fit the medium of the glue barrel, and the glue outlet 31 of the feeding pump 3 is connected to the filter 5. The feeding pump 3 is provided with a first heating member 6; the pressure plate 4 is provided with a second heating member; a temperature monitoring member, the feeding pump 3 and the pressure plate 4 are both provided with a temperature monitoring member for monitoring the temperature of their shells; a control module 7, the lifting member 2, the first heating member 6, the second heating member and the temperature monitoring member are all signal connected to the control module.

[0031] Specifically, the base 1 is used to securely position the glue barrel, ensuring stability and safety during glue feeding. Two lifters 2 are vertically and symmetrically mounted on the base 1. The telescopic ends of the two lifters 2 are connected to a support plate 21. The height of the support plate 21, its feed pump 3, and the pressure plate 4 are adjusted by controlling the extension and retraction of the lifters 2.

[0032] The feed pump 3 is fixedly mounted on the support plate 21 and serves as the core power source for the glue supply. A pressure plate 4 is located at the bottom of the pump 3. This platen 4 is designed to tightly contact the medium within the glue barrel, ensuring full contact and efficient glue extraction during the glue extraction process. Furthermore, a filter 5 is connected to the glue outlet 31 of the pump to remove impurities from the glue after it is extracted, ensuring the purity and stability of the glue supply.

[0033] The feed pump 3 is equipped with a first heating element 6, which heats or insulates the pump body and the glue inside when needed to improve the fluidity of the glue. Simultaneously, a second heating element is also provided on the pressure plate 4. By heating the pressure plate, it indirectly raises the temperature of the medium in the glue barrel in contact with it, helping to soften the glue and facilitate its extraction.

[0034] Temperature monitoring components are installed on the feed pump 3 and platen 4 to monitor their housing temperatures, ensuring that the heating process remains within a set safety range. By providing real-time feedback on the housing temperatures of the feed pump 3 and platen 4, the temperature monitoring components provide users with timely information on the heating status of the equipment and prevent potential safety hazards caused by overheating. Heating automatically stops when the temperature reaches the set value and restarts when the temperature drops below the set range.

[0035] The control module 7 establishes signal connections with the lifting element 2, the first heating element 6, the second heating element, and the temperature monitoring element. Users can input commands through the control module to precisely control and adjust various functions of the device, such as adjusting the height of the lifting element 2, setting the heating temperature, and monitoring the device's operating status. In summary, the glue supply device provided in this application ensures a continuous and uniform glue supply process and reduces glue extraction resistance and the risk of clogging.

[0036] The feed pump 3 of the present application can be directly used from the prior art, such as a glue pump device for insulating glass production disclosed in CN217664288U.

[0037] Based on the above embodiment, the bottom of the feed pump 3 is a hollow frustum 32, the cavity of the hollow frustum 32 is the input channel of the medium, and a fixed hole connected to the input channel is provided on the hollow frustum 32. The first heating element 6 is arranged in the fixed hole, and the heating end of the first heating element 6 can heat the medium entering the cavity and heat the shell of the hollow frustum 32.

[0038] That is to say, the cavity of the hollow frustum 32 is used as the input channel of the medium. A fixed hole is provided on the hollow frustum 32, and the first heating element 6 is placed in the fixed hole. Its heating end can directly act on the medium entering the cavity to preheat the glue, which helps to reduce the viscosity of the glue and improve its fluidity in the pipeline, thereby speeding up the glue supply speed and improving production efficiency.

[0039] At the same time, the first heating element 6 heats the medium and also heats the shell of the hollow frustum 32. The heating effect helps to reduce the temperature difference between the shell and the medium, further ensuring the stability and reliability of the glue supply process.

[0040] Based on the above embodiment, the first heating element 6 is a heating rod, and the feed pump 3 is made of aluminum. This means that the heating rod, as the first heating element 6, offers advantages such as rapid heating, controllable temperature, and a long service life. Furthermore, the aluminum feed pump is chosen for its excellent thermal conductivity and portability. Aluminum, a metal with high thermal conductivity, quickly transfers heat generated by the heating rod to the pump body and internal glue. As the heating rod heats the hollow cone 32, the aluminum feed pump also heats up simultaneously, achieving uniform heating of the entire pump body and the internal medium.

[0041] Based on the above embodiment, the pressure plate 4 is attached to the outside of the hollow frustum 32, and the second heating element heats up the medium in contact with the pressure plate 4. The second heating element is an electric heating wire or a heating rod, and the pressure plate 4 is an aluminum pressure plate.

[0042] In other words, the pressure plate 4 fits snugly around the outside of the hollow cone 32, ensuring it tightly covers the opening of the glue barrel, creating an effective sealing and heating area. When the pressure plate contacts the medium (glue) within the barrel, it effectively transfers heat to the medium, thereby increasing the medium's temperature and improving the glue's fluidity.

[0043] Secondly, the second heating element is selected to be a heating wire or a heating rod. These heating elements have the characteristics of rapid heating and controllable temperature. The second heating element is installed inside the pressure plate 4 or in close contact with it to transfer the generated heat to the pressure plate 4. When the heating wire or heating rod is energized and heated, the pressure plate 4, acting as a heat transfer medium, will quickly heat up and transfer the heat to the glue in contact with it.

[0044] In addition, the pressure plate 4 is made of aluminum. Aluminum is an excellent thermal conductive material with high thermal conductivity and good thermal uniformity. Therefore, the aluminum pressure plate can quickly and evenly absorb and transfer heat, ensuring that the glue in contact with it can be evenly heated.

[0045] Based on the above embodiment, the temperature monitoring component is a thermistor or a platinum thermal resistor; a driving wheel set 11 is provided at the bottom of the base 1.

[0046] That is to say, the temperature monitoring component is selected as a thermistor or a platinum thermal resistor, which can sense and accurately reflect the temperature of the feed pump 3 and the pressure plate 4 shell in real time, convert the temperature signal into an electrical signal and transmit it to the control module 7. The control module can accurately control the heating power of the first heating element 6 and the second heating element based on the received temperature data to ensure that the heating process is carried out within the set safety range and prevent overheating or insufficient temperature.

[0047] Secondly, a driving wheel set 11 is provided at the bottom of the base 1, so that it can be easily moved to different working positions as needed. The driving wheel set includes four universal wheels to achieve movement.

[0048] Preferably, the control module 7 can be a PLC, and the temperature control uses the PID principle. The pressure plate 4 or the feed pump 3 can be individually temperature controlled, and different temperatures can be set according to actual needs to ensure the optimal fluidity of the medium (glue).

[0049] Specifically, PLC (Programmable Logic Controller) is suitable for complex control tasks in industrial automation due to its powerful logic processing capabilities, flexible configuration options and high reliability.

[0050] For temperature control, the PID principle (proportional-integral-derivative control) is employed. This principle continuously monitors the difference between the actual temperature and the set point and adjusts the heating power accordingly to achieve precise temperature control. Specifically, the PID controller calculates the optimal control variable based on the effects of three parameters: proportional (P), integral (I), and differential (D). This adjusts the heating or cooling power to ensure that the actual temperature quickly and smoothly reaches and maintains the set point.

[0051] In addition, the system is flexible, allowing users to set different temperatures according to actual needs. This means that under different working conditions, users can adjust the temperature setting value to adapt to different types of glue or different production needs.

[0052] Based on the above embodiment, the lifting member 2 is a column cylinder, and the glue supply equipment further includes an air pressure regulating device and a main air source switch for providing power to the lifting member 2 and the feeding pump 3.

[0053] Specifically, to provide a stable and adjustable power source for the column cylinder and feed pump 3, the glue supply equipment is also equipped with an air pressure regulator and a main air source switch. The air pressure regulator is responsible for adjusting the air pressure supplied to the column cylinder and feed pump to meet the needs of different working scenarios. By precisely controlling the air pressure, it ensures that the column cylinder has sufficient power and stability during the lifting process, while also ensuring that the feed pump can maintain a stable flow rate and pressure when extracting glue.

[0054] When the equipment needs to be started, turn on the main air source switch, and the air source will be supplied to the column cylinder and feed pump through the air pressure regulating device; when the equipment needs to be stopped, turn off the main air source switch, and the entire pneumatic system will stop working.

[0055] Based on the above embodiment, the control module 7 is also provided with an alarm unit. When the temperature monitoring component detects that the temperature of the feed pump 3 or the pressure plate 4 exceeds a preset range, the alarm unit automatically triggers an alarm. The alarm unit includes a sound alarm component and / or a light alarm component.

[0056] In other words, the control module 7 is not only responsible for monitoring and regulating the operating status of various components, but also integrates an alarm unit to enhance the safety and reliability of the equipment. When a temperature monitoring device (such as a thermistor or platinum resistance thermometer) detects that the temperature of the feed pump 3 or the platen 4 exceeds a preset range, it indicates that overheating or abnormal operating conditions are occurring. To promptly notify the operator, the alarm unit in the control module 7 automatically triggers an alarm. The alarm unit may include an audible alarm component and / or a light alarm component. The audible alarm component attracts the operator's attention by emitting a piercing alarm sound, effectively conveying alarm information even in noisy working environments. The light alarm component, on the other hand, indicates abnormal conditions with a flashing light, which may include different colors of light to indicate different types of faults or alarm levels.

[0057] In addition, the alarm unit is integrated with a display screen to show specific fault information or temperature readings, so that operators can understand the problem more accurately.

[0058] Example 2:

[0059] See also Figure 3 The difference between this embodiment and embodiment 1 is that the pressure plate 4 is a 55-gallon pressure plate, and a roller 8 is provided on one side of the base 1.

[0060] That is to say, the pressure plate 4 of Example 1 is a 5-gallon pressure plate, which is suitable for smaller-sized glue barrels. When the glue barrel is replaced with a corresponding larger specification, the pressure plate 4 is selected as a 55-gallon pressure plate, and then the pressure plate 4 of the corresponding specification is selected according to the specification of the glue barrel. By setting the roller 8 and the height of the roller 8 being the same as the height of the base 1, the resistance and difficulty in moving the heavy glue barrel can be significantly reduced, and the safety of the operation can be improved. As a result, the glue barrel can be smoothly transitioned to the base 1 when rolling on the roller 8. The user only needs to gently push the glue barrel placed on the roller to easily transfer it to the base, reducing the labor intensity of manual handling and improving work efficiency.

[0061] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
