A uniformly stirred hot melt adhesive storage container and method

Abstract

This invention discloses a uniformly stirred hot melt adhesive storage container and method, belonging to the field of hot melt adhesive storage technology. It includes a device housing with an inlet pipe and an outlet pipe installed on it. A cover plate is provided at the top of the housing, and a rotating shaft is mounted on the cover plate. Stirring blades are provided on the outer surface of the rotating shaft. A lifting plate is provided inside the housing, and a telescopic spring connects the lifting plate to the housing. This invention achieves adaptive adjustment of the stirring driving force through the linkage of the lifting plate, the telescopic spring, and the transmission mechanism. The larger the amount of hot melt adhesive stored, the greater the pressure between the rotating disk and the rubber pad, and the greater the driving force transmitted from the drive motor to the rotating shaft, ensuring thorough stirring of a large amount of hot melt adhesive. Conversely, the smaller the storage volume, the smaller the driving force, preventing damage to small amounts of hot melt adhesive. This approach balances the stirring needs of different storage volumes, maintaining the uniformity of the hot melt adhesive and ensuring bonding performance.

Description

Technical Field

[0001] This invention belongs to the field of hot melt adhesive storage technology, specifically referring to a hot melt adhesive storage container and method with uniform stirring. Background Technology

[0002] Hot melt adhesives, as a commonly used bonding material, are widely used in packaging, electronics, building materials, and many other fields. The uniformity of their storage and mixing directly affects the bonding effect and user experience. Currently, hot melt adhesive storage containers on the market generally suffer from technical defects such as uneven mixing, poor compatibility, and cumbersome operation, making it difficult to meet actual production and usage needs.

[0003] The main shortcomings of existing technologies are as follows: the stirring method is simple, most storage containers only use a stirring structure with a fixed speed, which cannot adaptively adjust the stirring driving force according to the storage amount of hot melt adhesive. This results in a large amount of hot melt adhesive being insufficiently stirred and solidifying in layers, while a small amount of hot melt adhesive is damaged due to excessive driving force, affecting the adhesive performance of the hot melt adhesive.

[0004] To address the shortcomings of existing technologies, there is an urgent need to develop a uniformly stirred hot melt adhesive storage container with adaptive stirring adjustment. This would solve the technical problems of uneven stirring, poor adaptability, and inconvenient maintenance of existing containers, ensuring the quality of hot melt adhesive storage and stirring effect, and improving ease of use and work efficiency. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides a hot melt adhesive storage container and method for uniform stirring, which effectively solves the problems currently on the market.

[0006] The technical solution adopted by the present invention is as follows: The present invention proposes a uniformly stirred hot melt adhesive storage container, including a device shell, an inlet pipe installed on the device shell, an outlet pipe installed on the device shell, a cover plate provided at the top of the device shell, a rotating shaft provided on the cover plate, a stirring blade provided on the outer surface of the rotating shaft, a lifting plate provided inside the device shell, a telescopic spring connected between the lifting plate and the device shell, and a transmission rod installed on the upper surface of the telescopic spring.

[0007] Furthermore, a lifting ring is provided at the end of the transmission rod away from the lifting plate, a rotating disk is provided inside the lifting ring, a ball is installed on the rotating disk, a keyway is provided in the middle of the rotating disk, a fixing key is provided on the outer surface of the top end of the rotating shaft, a driven gear is installed on the rotating shaft, a rubber pad is provided on the upper surface of the driven gear, a drive motor is installed on the upper surface of the cover plate, the output end of the drive motor is connected to a rotating shaft, a drive gear is installed on the rotating shaft, and a closing ring is provided on the cover plate.

[0008] Furthermore, one end of the feed pipe passes through and is fixedly connected to the outer shell of the device, and one end of the discharge pipe passes through and is fixedly connected to the outer shell of the device. Both the feed pipe and the discharge pipe are equipped with one-way valves, and the one-way valves in the feed pipe and the discharge pipe are in opposite directions.

[0009] Furthermore, the cover plate is detachably connected to the housing of the device by bolts, and the rotating shaft passes through and rotatably connects to the cover plate and the housing of the device.

[0010] Furthermore, the stirring blades are evenly distributed on the outer surface of the rotating shaft, and the stirring blades are fixedly connected to the rotating shaft. The lifting plate is slidably connected inside the device housing, and the rotating shaft passes through and is rotatably connected to the lifting plate.

[0011] Furthermore, one end of the telescopic spring is fixedly connected to the housing of the device, the other end of the telescopic spring is fixedly connected to the lifting plate, and the transmission rods are evenly distributed on the upper surface of the lifting plate and are fixedly connected to the lifting plate.

[0012] Furthermore, the lifting ring is fixedly connected to the end of the transmission rod away from the lifting plate, the rotating disk is rotatably connected to the lifting ring, the rolling balls are evenly distributed on the rotating disk and are rotatably connected to the rotating disk, and the rolling balls abut against the lifting ring.

[0013] Furthermore, the fixed key is fixedly connected to the rotating shaft, and the fixed key is slidably connected in the keyway; the driven gear is rotatably connected to the rotating shaft; and the rubber pad is fixedly connected to the driven gear.

[0014] Furthermore, the drive motor is fixedly mounted on the cover plate, the rotating shaft is fixedly connected to the output end of the drive motor, the drive gear is fixedly connected to the rotating shaft, the drive gear meshes with the driven gear, the closed ring is fixedly connected to the cover plate, and the lifting ring is slidably connected to the closed ring.

[0015] Furthermore, a method of using a uniformly stirred hot melt adhesive storage container includes the following steps:

[0016] S1. Feeding preparation: The hot melt adhesive to be stored and stirred is slowly fed into the inner shell of the device through the feeding pipe to ensure that the hot melt adhesive falls accurately above the lifting plate. During the feeding process, the feeding is kept smooth to avoid hot melt adhesive spillage.

[0017] S2. Lifting Linkage Trigger: As hot melt adhesive is continuously injected, the downward pressure on the lifting plate gradually increases. When the pressure exceeds the supporting force provided by the telescopic spring, the lifting plate moves downward along the inner wall of the device housing. Simultaneously, the lifting plate drives the transmission rod connected to it to move downward, thereby driving the lifting ring at the top of the transmission rod to slide smoothly downward along the closed ring. At this time, the squeezing force between the rotating disk and the rubber pad installed on the driven gear increases synchronously, and the friction between the two increases accordingly, preparing for subsequent power transmission.

[0018] S3. Start the stirring mechanism: Start the drive motor installed on the cover plate. The drive motor drives the drive gear to rotate through the rotating shaft connected to the output end. The drive gear meshes with the driven gear, thereby driving the driven gear to rotate synchronously. The driven gear drives the rotating disk to rotate through the friction between the rubber pad and the rotating disk. The rotating disk engages with the fixed key at the top of the rotating shaft through its own keyway, driving the rotating shaft to rotate synchronously. The rotating shaft drives the stirring blades on its outer surface to rotate, uniformly stirring the hot melt adhesive inside the device shell.

[0019] S4. Adaptive stirring adjustment: During the stirring process, the amount of hot melt adhesive inside the device shell determines the magnitude of the extrusion pressure between the rotating disc and the rubber pad. The more hot melt adhesive there is, the greater the extrusion pressure, and the greater the driving force transmitted by the drive motor to the rotating shaft, ensuring that a large amount of hot melt adhesive can be effectively stirred. The less hot melt adhesive there is, the smaller the extrusion pressure and the smaller the driving force, avoiding damage to a small amount of hot melt adhesive due to excessive driving force.

[0020] S5. Hot melt adhesive dispensing: When it is necessary to dispense the well-stirred hot melt adhesive, open the discharge pipe. The hot melt adhesive inside the device casing will be discharged through the discharge pipe under its own gravity, thus completing the dispensing process. The dispensing speed can be controlled according to the needs during the dispensing process to avoid waste of hot melt adhesive.

[0021] S6. Device Reset: As hot melt adhesive is continuously discharged, the weight of the hot melt adhesive inside the device shell gradually decreases, and the downward pressure on the lifting plate decreases accordingly. When the pressure is less than the supporting force of the telescopic spring, the lifting plate moves upward and returns to its initial position under the action of the reset elastic force of the telescopic spring. The lifting plate simultaneously drives the transmission rod, lifting ring, rotating disk and driven gear to reset.

[0022] The beneficial effects achieved by the present invention using the above structure are as follows:

[0023] (1) By linking the lifting plate, the telescopic spring and the transmission mechanism, the adaptive adjustment of the stirring driving force is realized. The more hot melt adhesive is stored, the greater the squeezing force between the rotating plate and the rubber pad, and the greater the driving force transmitted by the drive motor to the rotating shaft, ensuring that a large amount of hot melt adhesive is stirred fully; the less the storage, the smaller the driving force, avoiding damage to a small amount of hot melt adhesive, taking into account the stirring needs of different storage amounts, always maintaining the uniformity of hot melt adhesive, and ensuring bonding performance.

[0024] (2) Both the feed pipe and the discharge pipe are equipped with one-way valves, and the one-way valves are in opposite directions to effectively prevent hot melt adhesive from flowing back and avoid spillage during feeding and discharging. At the same time, it prevents external air and impurities from entering the container and ensures the storage quality of hot melt adhesive. The closed ring protects the lifting ring and internal transmission components, reduces dust and debris interference, reduces component wear, and improves the stability of device operation.

[0025] (3) The entire usage process does not require complex parameter adjustment. Only simple steps such as feeding, starting the motor, picking up, and resetting are required. The adaptive adjustment function reduces manual intervention. The process can be directly repeated next time, making it easy to operate. The cover plate is detachably connected by bolts, which facilitates the cleaning, inspection and maintenance of internal components, shortens maintenance time and improves work efficiency.

[0045] A method for using a uniformly stirred hot melt adhesive storage container includes the following steps:

[0046] S1. Feeding preparation: The hot melt adhesive to be stored and stirred is slowly fed into the device housing 1 through the feed pipe 2, ensuring that the hot melt adhesive falls accurately above the lifting plate 7. During the feeding process, the feeding is kept smooth to avoid hot melt adhesive spillage.

[0047] S2. Lifting linkage trigger: As hot melt adhesive is continuously injected, the downward pressure on the lifting plate 7 gradually increases. When the pressure is greater than the supporting force provided by the telescopic spring 8, the lifting plate 7 moves downward along the inner wall of the device housing 1. The lifting plate 7 simultaneously drives the transmission rod 9 connected to it to move downward, thereby driving the lifting ring 10 at the top of the transmission rod 9 to slide smoothly downward along the closed ring 20. At this time, the squeezing force between the rotating disk 11 and the rubber pad 16 installed on the driven gear 15 increases synchronously, and the friction between the two increases accordingly, preparing for subsequent power transmission.

[0048] S3. Start the stirring mechanism: Start the drive motor 17 installed on the cover plate 4. The drive motor 17 drives the drive gear 19 to rotate through the rotating shaft 18 connected to the output end. The drive gear 19 meshes with the driven gear 15, thereby driving the driven gear 15 to rotate synchronously. The driven gear 15 drives the rotating disk 11 to rotate through the friction between the rubber pad 16 and the rotating disk 11. The rotating disk 11 cooperates with the fixed key 14 at the top of the rotating shaft 5 through the keyway 13 it has opened, driving the rotating shaft 5 to rotate synchronously. The rotating shaft 5 drives the stirring blades 6 on its outer surface to rotate, uniformly stirring the hot melt adhesive inside the outer shell 1 of the device.

[0049] S4. Adaptive stirring adjustment: During the stirring process, the amount of hot melt adhesive inside the outer shell 1 determines the magnitude of the extrusion pressure between the rotating disk 11 and the rubber pad 16. The more hot melt adhesive there is, the greater the extrusion pressure, and the greater the driving force transmitted from the drive motor 17 to the rotating shaft 5, ensuring that a large amount of hot melt adhesive can be effectively stirred. The less hot melt adhesive there is, the smaller the extrusion pressure and the smaller the driving force, avoiding damage to a small amount of hot melt adhesive due to excessive driving force.

[0050] S5. Hot melt adhesive dispensing: When it is necessary to dispense the well-stirred hot melt adhesive, open the discharge pipe 3. The hot melt adhesive inside the outer shell 1 will be discharged through the discharge pipe 3 under its own gravity, thus completing the dispensing. During the dispensing process, the dispensing speed can be controlled according to the needs to avoid waste of hot melt adhesive.

[0051] S6. Device Reset: As hot melt adhesive is continuously discharged, the weight of the hot melt adhesive inside the device housing 1 gradually decreases, and the downward pressure on the lifting plate 7 decreases accordingly. When the pressure is less than the supporting force of the telescopic spring 8, the lifting plate 7 moves upward and returns to its initial position under the reset force of the telescopic spring 8. The lifting plate 7 simultaneously drives the transmission rod 9, the lifting ring 10, the rotating disk 11, and the driven gear 15 to reset.

[0052] In practical use, hot melt adhesive is fed into the interior of the device housing 1 through the feed pipe 2. The hot melt adhesive inside the device housing 1 is positioned above the lifting plate 7. With the continuous injection of hot melt adhesive, the downward pressure on the lifting plate 7 increases continuously and overcomes the supporting force provided by the telescopic spring 8, causing it to move downward inside the device housing 1. The lifting plate 7 drives the transmission rod 9 to move downward synchronously, thereby causing the lifting ring 10 to slide downward along the closed ring 20. At this time, the squeezing force between the rotating disk 11 and the rubber pad 16 installed on the driven gear 15 increases accordingly, and the friction between the rotating disk 11 and the rubber pad 16 increases synchronously.

[0053] Start the drive motor 17. The drive motor 17 drives the drive gear 19 to rotate via the rotating shaft 18. The drive gear 19 meshes with the driven gear 15, causing the driven gear 15 to rotate synchronously. The driven gear 15 drives the rotating disk 11 to rotate via the friction between the rubber pad 16 and the rotating disk 11. The rotating disk 11 drives the rotating shaft 5 to rotate via the cooperation between the keyway 13 and the fixed key 14. In turn, the rotating shaft 5 stirs the hot melt adhesive inside the device housing 1 through the stirring blade 6. The more hot melt adhesive inside the device housing 1, the greater the squeezing force between the rotating disk 11 and the rubber pad 16, and the greater the driving force transmitted by the drive motor 17 to the rotating shaft 5. Conversely, the smaller the driving force received by the rotating shaft 5, the more effective the stirring of the hot melt adhesive can be achieved when the amount of hot melt adhesive is large, while avoiding damage to the hot melt adhesive when the amount of hot melt adhesive is small.

[0054] When hot melt adhesive is needed, the discharge pipe 3 is opened, and the hot melt adhesive is discharged through the discharge pipe 3. As the amount of hot melt adhesive decreases, the lifting plate 7 returns to the initial position under the action of the telescopic spring 8. The above is the overall working process of the present invention. This step can be repeated next time it is used. The actual operation process is very simple and easy.
