[0028] In the industrial production application of dispensing, a device is usually used to hold the dispensing liquid, such as a tank or barrel. The device is made sealed, the top of the device is pressurized, and the bottom of the glue outlet pipe is connected to the dispensing valve or the glue spray head. The dispensing action is controlled by controlling the switch of the dispensing valve or the glue spray head.
[0029] In practical applications, some special glues (such as glues with high viscosity or glues that are easy to solidify at low temperatures) usually need to be heated to make the temperature of the glue point reach 100°C or even higher, thereby increasing its fluidity or moving it away from the solidification point to avoid clogging. Finally, it is sprayed onto the target workpiece through a dispensing valve or a spray head.
[0030] In actual production, two heating methods are usually used. First, a metal tank is used as a glue storage device, and then the tank is heated to make the glue inside the tank reach the required temperature. In order for the dispensing valve or the glue spray head to reach the required glue outlet temperature, the heating temperature of the metal tank must be higher than the temperature requirement, because the flow channel in the middle will cause heat loss. The longer the glue outlet pipe, the greater the heat loss. Therefore, the metal tank needs to maintain a higher temperature, which increases energy consumption; secondly, the metal tank needs to be sealed and maintained at a high temperature, which requires a higher operating temperature for the sealing components. Long-term high temperature environment can easily cause the sealing components to age, increasing maintenance costs; thirdly, when the glue is used up and glue needs to be added, the metal tank must be completely cooled or cooled to a certain temperature before adding or replacing the glue, which affects the working time of the machine and leads to low production efficiency;
[0031] Secondly, use a rubber hose or rubber barrel as a glue storage device, do not heat it, only heat the glue dispensing valve or glue spray head, so that the temperature of the glue outlet point directly reaches the required requirements. However, when this heating scheme encounters a high-viscosity glue, in order to increase the fluidity of the glue, the air pressure added to the top of the glue storage device can only be increased. When the air pressure increases, the sealing structure of the glue storage device is more demanding, especially when glue needs to be added or replaced in subsequent production, the glue storage device will be repeatedly opened and sealed, so it is more difficult to maintain the sealing of the glue storage device; and the glue storage device is not thermostatic, and is not suitable for glue with a low curing temperature point. The glue is easy to solidify in the glue storage device or glue outlet device due to low temperature and block the machine.
[0032] In order to solve the above problems, the utility model proposes a glue liquid heating system, which includes:
[0033] The glue storage device 110 includes a container 112 and a glue storage heating module 113;
[0034] A glue feeding device 120, the glue feeding device 120 comprises a glue feeding tube 121 and a glue feeding heating module 122, and the container 112 is in communication with the glue feeding tube 121; and
[0035] The glue dispensing device 130 includes a glue dispensing valve and a glue dispensing heating module, and the glue delivery tube 121 is connected to the glue dispensing valve.
[0036] In this embodiment, the glue storage device 110, the glue feeding device 120 and the glue dispensing device 130 are heated in stages to avoid the entire device being at the high temperature required by the glue dispensing device 130 when dispensing glue, thereby reducing energy consumption in production.
[0037] Specifically, the glue storage heating module 113 heats the container 112 to 30-50°C, so that the glue with a lower curing temperature point is not easy to solidify in a low-temperature working environment; due to the low heating temperature, when adding glue or changing glue, it is not necessary to wait for the container 112 to cool down before operation; the 30-50°C environment does not require the container 112 to use expensive seals or complex sealing structures, which not only reduces the difficulty and cost of sealing the container 112, but also effectively ensures the sealing of the container 112 after multiple disassembly for adding glue or changing glue. The glue feeding heating module 122 heats the glue feeding tube 121 to 60-90°C, avoiding the loss of heat in the glue feeding tube 121, and at the same time makes the temperature of the glue liquid as close as possible to the temperature required for dispensing, speeding up the speed of the dispensing valve to heat the glue liquid to a higher temperature, and facilitating high-speed dispensing. The dispensing heating module heats the dispensing valve to 100-200°C. Under high temperature conditions, the glue liquid has better fluidity, which helps to increase the speed of dispensing and control the shape of the glue dots.
[0038] In one embodiment, the glue heating system further includes a temperature controller, which is used to control the glue storage heating module 113, the glue feeding heating module 122 and the glue dispensing heating module to reach a preset temperature.
[0039] In this embodiment, a first temperature sensor is also provided in the container 112, a second temperature sensor is provided at the glue delivery tube 121, and a third temperature sensor is provided at the glue dispensing valve. The first, second and third temperature sensors are used to detect the temperature of the glue in the container 112, the glue delivery tube 121 and the glue dispensing valve, respectively. The temperature controller controls each heating module to start or stop heating according to the temperature information fed back by the temperature sensor, so that the glue in the container 112, the glue delivery tube 121 and the glue dispensing valve always maintains a preset temperature.
[0040] In one embodiment, the glue feeding heating module 122 is wound around the glue feeding tube 121 .
[0041] In this embodiment, since the glue delivery tube 121 is relatively long, in order to ensure that the temperature of the glue liquid in the glue delivery tube 121 is kept consistent, the glue delivery heating module 122 of the glue delivery tube 121 is wound around the outside of the glue delivery tube 121, that is, the glue delivery heating module 122 is spirally arranged outside the glue delivery tube 121, thereby avoiding the loss of heat in the delivery channel. In addition, the temperature of the glue delivery tube 121 is between 60 and 90°C, so the main body of the glue delivery tube 121 can be a rubber tube with a relatively low temperature resistance, thereby reducing the production cost.
[0042] The present utility model also proposes a glue dispensing machine 100, which includes a glue liquid heating system. The specific structure of the heating system refers to the above-mentioned embodiment. Since the present utility model adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.
[0043] In one embodiment, the container 112 is provided with a containing cavity for containing liquid and a liquid inlet 112a connected to the containing cavity. The glue dispensing machine 100 also includes a glue adding device 140. The glue adding device 140 includes a valve 141. The valve 141 is used to open or cover the liquid inlet 112a.
[0044] In this embodiment, when it is necessary to add or replace glue in the receiving chamber, the valve 141 is opened, and the replaced glue enters the receiving chamber from the liquid inlet 112a. After adding or replacing glue, the valve 141 is closed, thereby ensuring the airtightness of the container 112 and reducing the heat loss of the container 112. Optionally, in this embodiment, the inner wall of the container 112 can also be provided with a non-stick coating, thereby effectively preventing glue from sticking to the wall and improving the situation of glue sticking to the wall.
[0045] In one embodiment, the glue adding device 140 further includes a funnel 142 . The funnel 142 is connected to the container 112 and communicates with the liquid inlet 112 a . The valve 141 is connected to one end of the funnel 142 close to the container 112 .
[0046] In this embodiment, the funnel 142 is provided to make the glue adding operation more convenient and prevent the glue liquid from overflowing from the liquid inlet 112a during glue adding.
[0047] In one embodiment, the glue dispensing machine 100 further includes a pressurizing device 150 . The container 112 is provided with an air inlet. The pressurizing device 150 is located at the air inlet. The pressurizing device 150 is used to increase the air pressure in the container 112 .
[0048] In this embodiment, in order to allow glue with high viscosity and poor flowability to flow smoothly from the container 112 into the glue delivery tube 121, a pressurizing device 150 is provided. The pressurizing device 150 includes an air inlet pipe, one end of which is connected to the air inlet, and the other end is connected to a compressed air source. The compressed air source provides gas to the container 112, so that the air pressure near the liquid inlet 112a in the container 112 increases. Due to the squeezing of the gas at the liquid inlet 112a, the glue in the container 112 continuously flows in a direction away from the liquid inlet 112a, and is thus introduced into the glue delivery tube 121. By providing the pressurizing device 150 in this embodiment, the glue dispensing machine 100 is adapted to glue with high viscosity.
[0049] In one embodiment, the pressurizing device 150 further includes a pressure gauge 151 , which is connected to the container 112 and is used to detect the air pressure in the container 112 .
[0050] In this embodiment, in order to check the airtightness of the container 112, when compressed air is continuously injected into the container 112, if the reading of the pressure gauge 151 is the same as the value of the external air pressure, the airtightness of the container 112 is insufficient, reminding the operator to maintain the container 112.
[0051] In one embodiment, the pressurizing device 150 further includes a safety valve connected to the container 112 .
[0052] In this embodiment, in order to prevent the container 112 from exploding due to excessive air pressure in the container 112 when compressed air is continuously injected into the container 112, a safety valve is provided to communicate with the container 112. When the air pressure in the container 112 exceeds a preset value, the safety valve automatically opens to discharge the remaining air, thereby improving the safety of the entire device.
[0053] In one embodiment, the dispensing machine 100 further includes a liquid level detector, which is connected to the container 112 and is used to detect the height of the liquid level in the containing cavity.
[0054] In this embodiment, the liquid level detector is located in the container 112. The liquid level detector is used to monitor the height of the liquid in the container 112. Through the liquid level detector, it can be prompted to add glue when there is too little glue to prevent the glue from being too little and affecting the use.
[0055] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
