[0001] The present application relates to the field of melt glue technology, and in particular to a glue material pressure control device on a melt glue automatic glue filling machine. Background Art

[0002] Melt adhesive technology is widely used in modern manufacturing, especially in the automotive, electronics, packaging and other industries. Melt adhesive is usually used to achieve reliable connection between parts of different materials. With the increasing awareness of environmental protection, hot melt adhesive, as a high-performance environmentally friendly adhesive, has gradually become the mainstream choice. It does not contain water and solvents, has a solid content of 100%, can effectively reduce environmental pollution, and has the advantages of improving production efficiency and product quality.

[0003] In industry, hot melt adhesive is often used through a sol-gel automatic glue filling machine. The sol-gel automatic glue filling machine includes equipment such as a storage barrel, a delivery pump, a delivery pipe, and a glue filling gun. The adhesive is stored in the storage barrel, and the delivery pump operates to deliver the adhesive through the delivery pipe to the glue filling gun for use.

[0004] During the actual application of the above-mentioned glue filling machine, the glue is prone to condensation in the storage barrel, resulting in insufficient pressure of the delivery pump, and unable to ensure the stable flow of the glue in the delivery pipe, thereby reducing product quality. Summary of the invention

[0005] In order to improve the problems existing in the above-mentioned technology, the present application provides a glue pressure control device on an automatic glue filling machine.

[0006] The present application provides a glue pressure control device on a melt-glue automatic glue filling machine, which adopts the following technical solution: A glue pressure control device on an automatic glue dispensing machine comprises a material storage barrel, a delivery pump and a glue dispensing gun, wherein the material discharge port of the material storage barrel and the delivery pump, as well as the delivery pump and the glue dispensing gun are connected via a delivery pipe; a heating element and a stirring element are arranged in the material storage barrel, a pressure gauge is arranged on the delivery pipe, and the heating element and the stirring element are electrically connected to the pressure gauge; a filter plate is arranged in the material storage barrel, the material discharge port of the material storage barrel is located below the filter plate, and a plurality of filter holes are opened on the filter plate.

[0007] By adopting the above technical solution, the storage barrel is used to store the rubber material. When the glue filling machine is used, the delivery pump operates to deliver the rubber material in the storage barrel to the glue filling gun, and the glue filling gun thus completes the use of the rubber material. During this process, the pressure gauge monitors the pressure in the delivery pipe in real time. When the pressure value detected by the pressure gauge is low, the pressure gauge sends a signal, and the heating element and the stirring element receive the signal to operate. The heating element heats the rubber material in the storage barrel, and the stirring element stirs the rubber material, thereby making the rubber material have good fluidity. After the rubber material flows into the filter plate and passes through the filter hole, it enters the space below the filter plate, and the delivery pump operates to deliver the rubber material to the glue filling gun through the delivery pipe.

[0008] The cooperation of the heating element, stirring element and pressure gauge in this equipment can monitor and control the rubber in the feed pipe and the discharge pipe in real time to avoid the condensation of the rubber in the storage barrel. With the cooperation of the filter plate, it can ensure that the rubber has good fluidity when flowing through the feed pipe, thereby controlling the rubber pressure in the feed pipe.

[0010] By adopting the above technical solution, the first driving member is used to receive the signal to drive the main shaft to rotate. The rotation of the main shaft drives the stirring blade and the push rod to rotate synchronously. The stirring blade rotates to stir the rubber material in the storage barrel to prevent the rubber material from coagulating. The push rod rotates to push the rubber material on the filter plate, thereby speeding up the speed of the rubber material passing through the filter plate and ensuring that the rubber material can quickly pass through the filter hole and be delivered to the delivery pipe by the delivery pump.

[0012] By adopting the above technical solution, the rotation of the main shaft drives the push rod to rotate, and the extension rod rotates synchronously with the push rod. When the extension rod rotates to above the corresponding filter hole, the second driving member operates to drive the extension rod to move in the direction close to the filter plate. The extension rod can be inserted into the filter hole to clear the filter hole, making the filter hole unobstructed and preventing the rubber from adhering to the filter hole.

[0014] By adopting the above technical solution, the rotation of the main shaft drives the push rod and the extension rod to rotate synchronously. When the extension rod is not inserted into the filter hole, the bottom end of the extension rod abuts against the filter plate, and the telescopic spring is compressed and in a compressed state; when the extension rod rotates to the top of the filter hole following the push rod, the telescopic spring is not compressed and drives the extension rod to be inserted into the filter hole, thereby clearing the filter hole, and driving the extension rod through the telescopic spring, and the driving method is flexible and convenient. The accommodating cavity is used to protect the telescopic spring, preventing the telescopic spring from being directly exposed to the outside and affected by the rubber material, thereby preventing the compression and tension state of the telescopic spring from being disturbed.

[0015] Optionally, the second driving member includes a telescopic rod, a fixed end of the telescopic rod is connected to the push rod, and a movable end is connected to the plurality of extension rods via a connecting rod.

[0016] By adopting the above technical solution, when the extension rod moves to above the filter hole, the telescopic rod drives the movable end to perform telescopic movement, and the movable end of the telescopic rod thereby drives the connecting rod to move in a direction close to the filter plate, and the extension rod then follows the connecting rod to move synchronously and is inserted into the filter hole, thereby clearing the filter hole.

[0017] Optionally, a partition plate is provided in the material storage barrel, and the partition plate divides the space in the material storage barrel into a material storage chamber and a protective chamber, and the rubber is stored in the material storage chamber; a synchronization rod is provided on the main shaft, and the synchronization rod is located in the protective chamber, and a sensor for sensing the position of the synchronization rod is provided in the protective chamber, and the sensor is electrically connected to the telescopic rod.

[0018] By adopting the above technical solution, the partition plate divides the space in the storage barrel into a storage chamber and a protective chamber, thereby dividing the area where the rubber material in the storage barrel is located. The rubber material is stored in the storage chamber, and the sensor and the synchronization rod are located in the protective chamber. The sensor is used to sense the position of the synchronization rod. The position of the synchronization rod can be used to obtain information about the position of the push rod, thereby ensuring that the extension rod on the push rod can be accurately inserted into the filter hole, avoiding deviation between the position of the extension rod and the position of the filter hole. The sensor and the synchronization rod are arranged in the protective chamber to prevent their operation from being affected by the rubber material.

[0019] Optionally, one end of the extension rod close to the filter plate is in a pointed cone shape.

[0020] By adopting the above technical solution, the bottom end of the extension rod, that is, the end close to the filter plate, is in a pointed cone shape, which is conducive to the connection between the extension rod and the filter hole, and further facilitates the extension rod to be inserted into the filter hole.

[0021] Optionally, the heating element includes an electric heating rod arranged in the main shaft, a power supply is arranged on the storage barrel, the power supply is electrically connected to the pressure gauge, the power supply is arranged with an electric contact, the electric heating rod is provided with a distribution ring in contact with the electric contact, and the electric contact is slidably connected to the distribution ring.

[0022] By adopting the above technical solution, the power supply receives the signal and works. The power supply supplies power to the electric heating rod through the contact between the electric contact and the power distribution ring, and the temperature of the electric heating rod rises. Since the electric heating rod is located in the main shaft, the temperature of the main shaft rises, and the main shaft can directly contact the rubber in the storage barrel, so that the rubber can be efficiently and evenly heated. The rotation of the main shaft will drive the electric heating plate to rotate synchronously, and the cooperation of the electric contact and the power distribution ring can ensure that the electric heating plate is continuously heated during the rotation process.

[0023] Optionally, a heating chamber is circumferentially opened in the side wall of the storage barrel, and the heating element includes a heating tube spirally arranged in the heating chamber. The storage barrel is provided with a control element for controlling the temperature of the heating tube, and the control element is electrically connected to the pressure gauge.

[0024] By adopting the above technical solution, the control component receives the signal and works, the temperature of the heating tube rises, thereby causing the temperature of the side wall of the storage barrel to rise, thereby achieving heating of the rubber in the storage barrel. Since the heating tube is spirally arranged in the heating chamber, it can achieve a uniform increase in the temperature of each area in the storage barrel when heating, and the rubber in the storage barrel is heated evenly.

[0025] Optionally, the feed pipe is coated with thermal insulation cotton.

[0026] By adopting the above technical solution, the rubber material flowing in the conveying pipe can be insulated by coating the conveying pipe with thermal insulation cotton, thereby preventing the rubber material from condensing in the conveying pipe due to temperature drop.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1.

[0030] The following is combined with Figure 1-6 This application is described in further detail.

[0031] Example 1 Embodiment 1 of the present application discloses a glue pressure control device on a melt glue automatic glue filling machine. Figure 1 and Figure 2The glue pressure control device on the automatic glue filling machine includes a storage barrel 1, a delivery pump 2 and a glue filling gun 3.

[0032] The delivery pump 2 operates to deliver the glue in the storage barrel 1 to the glue gun 3, and the pressure gauge 6 monitors the pressure in the delivery pipe 4 in real time during this process; when the pressure value detected by the pressure gauge 6 is low, the pressure gauge 6 sends a signal, and the heating element and the stirring element 5 receive the signal to operate, the heating element heats the glue in the storage barrel 1, and the stirring element 5 stirs the glue, and the glue flows into the filter plate 7 and passes through the filter hole 8, and then enters the space below the filter plate 7, and the delivery pump 2 operates to deliver the glue to the glue gun 3 through the delivery pipe 4.

[0033] Reference Figure 3 The stirring member 5 includes a main shaft 51 and a plurality of stirring blades 52 disposed in the storage barrel 1. The plurality of stirring blades 52 are evenly disposed along the circumference and axial direction of the main shaft 51 and are fixedly connected to the main shaft 51. The main shaft 51 is disposed vertically and is rotatably connected to the storage barrel 1. The storage barrel 1 is provided with a first driving member for driving the main shaft 51 to rotate. The first driving member is electrically connected to the pressure gauge 6. The first driving member is used to receive a signal to drive the main shaft 51 to rotate. The rotation of the main shaft 51 drives the stirring blades 52 and the push rod 12 to rotate synchronously. The stirring blades 52 rotate to stir the rubber in the storage barrel 1 to prevent the rubber from condensing.

[0034] In the embodiments of this application, refer to Figure 3 The first driving member is selected as a driving motor 9, which is electrically connected to the pressure gauge 6. The driving motor 9 is installed and fixed on the top of the storage barrel 1. A driving bevel gear 10 is coaxially fixed on the output shaft of the driving motor 9; the top of the main shaft 51 extends to the outside of the storage barrel 1, and a driven bevel gear 11 is coaxially fixed on the main shaft 51. The driven bevel gear 11 is meshed with the driving bevel gear 10. The rotation of the output shaft of the driving motor 9 drives the driving bevel gear 10 to rotate, and the driven bevel gear 11 rotates thereby, thereby realizing the synchronous rotation of the main shaft 51.

[0035] Reference Figure 3 and Figure 4A push rod 12 is fixed at the bottom of the main shaft 51, and the push rod 12 is fixedly connected to the main shaft 51. There is a gap between the push rod 12 and the filter plate 7, and the push rod 12 is used to push the rubber on the filter plate 7 to quickly pass through the filter plate 7. A plurality of extension rods 13 are vertically slidably arranged on the push rod 12, and the end of the extension rod 13 close to the filter plate 7 is in a pointed cone shape. A second driving member is arranged on the push plate, and the second driving member is used to drive the extension rod 13 to move in a direction close to the filter plate 7 and insert into the filter hole 8. The filter hole 8 is cleared by the extension rod 13, so that the filter hole 8 is unobstructed, and the rubber is prevented from adhering to the filter hole 8.

[0036] Reference Figure 3 and Figure 4 A accommodating chamber 14 is provided in the push rod 12, and the second driving member includes a plurality of telescopic springs 15 arranged in the accommodating chamber 14. The telescopic springs 15 are vertically arranged, and the position and number of the telescopic springs 15 are consistent with the extension rod 13. One end of the telescopic spring 15 is fixedly connected to the push rod 12, and the other end is fixedly connected to the corresponding extension rod 13.

[0037] When the extension rod 13 is not inserted into the filter hole 8, the bottom end of the extension rod 13 abuts against the filter plate 7, and the telescopic spring 15 is compressed and in a compressed state; when the extension rod 13 follows the push rod 12 to rotate above the filter hole 8, the telescopic spring 15 is not compressed and drives the extension rod 13 to be inserted into the filter hole 8, thereby clearing the filter hole 8, and the extension rod 13 is driven by the telescopic spring 15, and the driving method is flexible and convenient. The accommodating chamber 14 is used to protect the telescopic spring 15, to prevent the telescopic spring 15 from being directly exposed to the outside and affected by the rubber material, thereby preventing the compression and tension state of the telescopic spring 15 from being disturbed.

[0038] Reference Figure 2 and Figure 3 The feed pipe 4 is coated with heat-insulating cotton, the heating element includes an electric heating rod 22 arranged in the main shaft 51, the storage barrel 1 is provided with a power supply 23, the power supply 23 is electrically connected to the pressure gauge 6, the power supply 23 is provided with an electric contact (not shown in the figure), and the electric heating rod 22 is provided with a distribution ring (not shown in the figure) in contact with the electric contact, and the electric contact is slidably connected to the distribution ring.

[0039] The power supply 23 receives the signal and works. The power supply 23 supplies power to the electric heating rod 22 through the contact between the electric contact and the power distribution ring. The temperature of the electric heating rod 22 rises. Since the electric heating rod 22 is located in the main shaft 51, the temperature of the main shaft 51 rises. The main shaft 51 can directly contact the rubber in the storage barrel 1, and the rubber can be efficiently and evenly heated. The rotation of the main shaft 51 will drive the electric heating plate to rotate synchronously. The cooperation of the electric contact and the power distribution ring can ensure that the electric heating plate is continuously heated during the rotation process.

[0040] Reference Figure 2 and Figure 3A heating chamber 24 is circumferentially provided in the side wall of the storage barrel 1. The heating element further includes a heating tube 25 spirally arranged in the heating chamber 24. A control element 26 for controlling the temperature of the heating tube 25 is provided on the storage barrel 1. The control element 26 is electrically connected to the pressure gauge 6.

[0041] The control unit 26 receives the signal and starts working, the temperature of the heating tube 25 rises, thereby increasing the temperature of the side wall of the storage barrel 1, thereby heating the rubber in the storage barrel 1. Since the heating tube 25 is spirally arranged in the heating chamber 24, it can achieve a uniform increase in the temperature of each area in the storage barrel 1 when heating, and the rubber in the storage barrel 1 is heated evenly.

[0042] The implementation principle of the glue pressure control device on the automatic glue filling machine of the melt glue in the embodiment 1 of the present application is as follows: the storage barrel 1 is used to store the glue. When the glue filling machine is in use, the delivery pump 2 operates to deliver the glue in the storage barrel 1 to the glue filling gun 3, and the glue filling gun 3 thus completes the use of the glue. During this process, the pressure gauge 6 monitors the pressure in the delivery pipe 4 in real time. When the pressure value detected by the pressure gauge 6 is low, the pressure gauge 6 sends a signal, and the heating element and the stirring element 5 receive the signal to operate. The heating element heats the glue in the storage barrel 1, and the stirring element 5 stirs the glue, thereby making the glue have good fluidity. After the glue flows into the filter plate 7 and passes through the filter hole 8, it enters the space below the filter plate 7, and the delivery pump 2 operates to deliver the glue to the glue filling gun 3 through the delivery pipe 4.

[0043] The mutual cooperation of the heating element, the stirring element 5 and the pressure gauge 6 in the present device can monitor and control the rubber in the feed pipe 4 and the discharge pipe in real time, so as to avoid the condensation of the rubber in the storage barrel 1. With the cooperation of the filter plate 7, it can ensure that the rubber has good fluidity when flowing through the feed pipe 4, thereby controlling the pressure of the rubber in the feed pipe 4.

[0044] Example 2 The difference between Example 2 and Example 1 is that: Figure 5 and Figure 6 The second driving member includes an electrically controlled telescopic rod 16 , a fixed end of the telescopic rod 16 is fixedly connected to the push rod 12 , and a movable end is fixedly connected to the plurality of extension rods 13 via a connecting rod 27 .

[0045] Reference Figure 5 A partition plate 17 is fixed on the top of the storage barrel 1, and the partition plate 17 divides the space in the storage barrel 1 into a storage chamber 18 and a protective chamber 19, and the rubber is stored in the storage chamber 18; a synchronization rod 20 is fixed on the main shaft 51, and the synchronization rod 20 and the push rod 12 are in the same plane. The synchronization rod 20 is located in the protective chamber 19, and a sensor 21 for sensing the position of the synchronization rod 20 is provided in the protective chamber 19, and the sensor 21 is electrically connected to the telescopic rod 16.

[0046] The implementation principle of Example 2 is: when the extension rod 13 moves to above the filter hole 8, the telescopic rod 16 drives the movable end to telescope, and the movable end of the telescopic rod 16 thereby drives the connecting rod 27 to move in a direction close to the filter plate 7, and the extension rod 13 then moves synchronously with the connecting rod 27 and is inserted into the filter hole 8, thereby clearing the filter hole 8.

[0047] The partition plate 17 divides the space in the storage barrel 1 into a storage chamber 18 and a protective chamber 19, thereby dividing the area where the rubber material in the storage barrel 1 is located. The rubber material is stored in the storage chamber 18, and the sensor 21 and the synchronization rod 20 are located in the protective chamber 19. The sensor 21 is used to sense the position of the synchronization rod 20. The position of the push rod 12 can be obtained through the position of the synchronization rod 20, thereby ensuring that the extension rod 13 on the push rod 12 can be accurately inserted into the filter hole 8, avoiding the position of the extension rod 13 and the position of the filter hole 8. The sensor 21 and the synchronization rod 20 are arranged in the protective chamber 19 to prevent their operation from being affected by the rubber material.
