A production equipment for reactive polyurethane hot melt adhesive for edge sealing

Abstract

This utility model relates to the field of hot melt adhesive technology and discloses a production equipment for reactive polyurethane hot melt adhesive for edge sealing. It includes a base plate, a drive motor mounted on the top of the base plate, and a cam sleeved on the outer side of the drive motor's output shaft. The surface of the cam abuts against a U-shaped frame. This utility model, by setting a rotating component, starts the drive motor, causing the drive motor's output shaft to rotate with the cam. This causes the U-shaped frame to move back and forth continuously via a connecting strip and a U-shaped plate. During this process, the connecting gear reciprocates due to the meshing action of the fixed toothed plate, causing the rotating rod to reciprocate with the square sleeve. Under the action of the square block, the stirring rod reciprocates, causing the liquid in the mixing drum to initially move in one direction. When the stirring rod changes direction, the material continues to rotate under inertia, resulting in more thorough contact between the stirring rod and the material, thereby improving the mixing uniformity of the device.

Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive technology, and in particular to a production equipment for reactive polyurethane hot melt adhesive for edge sealing. Background Technology

[0002] Hot melt adhesive is a type of plastic adhesive whose physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and odorless, and is an environmentally friendly chemical product. Because the product itself is solid, it is easy to package, transport, and store. It is solvent-free, pollution-free, and non-toxic. In addition, it has advantages such as simple production process, high added value, high bonding strength, and fast speed.

[0003] Chinese utility model patent CN210138625U discloses a fully automatic hot melt adhesive production equipment for hot melt sleeves. By setting up a drive motor, the drive motor drives the second gear and the second rotating shaft to rotate. At this time, the second gear drives the first rotating shaft to rotate through the first gear, and the rotation directions of the first rotating shaft and the second rotating shaft are opposite. This causes the first spiral blade and the second spiral blade to move the raw material in opposite directions during the stirring process, so as to more comprehensively and thoroughly stir the raw material. At the same time, the circular plate, brush and filter plate can filter the raw material added to the box. The brush can push the raw material to rotate, thereby accelerating the filtration efficiency of the raw material. This device can reduce the possibility of the raw material affecting the processing progress to a certain extent.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist:

[0005] In actual use, the device mixes raw materials by stirring. However, during the stirring process between the material and the liquid, the material is stirred by the first and second spiral blades under the action of centrifugal force, which affects the exchange of materials in the liquid and thus affects the uniformity of the mixing. In addition, the material and liquid need to be cleaned after mixing. However, the stirring rod and the stirring cylinder are an integral sealed structure, which makes the cleaning of the device quite troublesome. Utility Model Content

The top and bottom of the vertical rod are fixedly connected to the top and bottom of the inner wall of the left vertical slot, respectively.

[0010] As a further improvement to the above solution, a rotary bearing is installed on the surface of the rotating rod, and the top of the rotary bearing is installed at the bottom of the stirring drum to ensure the normal rotation of the rotating rod.

[0011] As a further improvement to the above solution, two limiting grooves are provided on the top of the base plate, and the bottom of the U-shaped plate is slidably disposed inside the limiting grooves to ensure the normal movement of the U-shaped plate.

[0012] As a further improvement to the above solution, the top of the mixing drum is connected to two feed pipes, and the bottom of the mixing drum is connected to a drain pipe. A valve is installed on the surface of the drain pipe to facilitate the control of material entry and exit.

[0013] As a further improvement to the above solution, a support base is installed at the bottom of the mobile motor, and the surface of the support base is fixedly connected to the surface of the lifting trough plate, ensuring the normal operation of the mobile motor.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model, by setting a rotating component, allows materials and liquids to be introduced into the mixing drum through the feed pipe during use. Starting the drive motor causes the output shaft of the drive motor to rotate with the cam, which in turn causes the U-shaped frame to move back and forth continuously via the connecting strip and the U-shaped plate. During this process, the connecting gear reciprocates due to the meshing action of the fixed tooth plate, causing the rotating rod to reciprocate with the square sleeve. Under the action of the square block, the stirring rod reciprocates, causing the liquid in the mixing drum to initially move in one direction. When the stirring rod changes direction, the material continues to rotate under the action of inertia, resulting in more thorough contact between the stirring rod and the material, thereby improving the mixing uniformity of the device.

[0018] 2. This utility model, by setting up a moving component, requires cleaning of the device after mixing. Starting the rotary motor causes the threaded rod to rotate, and under the action of the lifting block, the lifting trough plate moves vertically, causing the top cover to move upwards and disengage the mixing rod from the mixing drum. Then, starting the moving motor causes the adjusting screw to rotate, moving the moving block along with the top cover, misaligning the top cover and the mixing drum for separate cleaning of the mixing rod and drum, resulting in a more thorough cleaning. After cleaning, starting the rotary motor and the moving motor resets the top cover, allowing the square block to re-insert into the square sleeve, making the device easier to close.

[0028] The rotating assembly is used to control the rotation of the stirring rod 16. The rotating assembly includes a square sleeve 6, on which two L-shaped scrapers 7 are fixedly connected. A rotating rod 8 is fixedly connected to the bottom of the square sleeve 6. A rotating bearing is installed on the surface of the rotating rod 8. The top of the rotating bearing is installed at the bottom of the stirring drum 5 to ensure the normal rotation of the rotating rod 8. A connecting gear 9 is fixedly connected to the bottom end of the rotating rod 8. A fixed toothed plate 10 is meshed on the surface of the connecting gear 9. The bottom of the fixed toothed plate 10 is fixedly connected to the top of the base plate 1.

[0029] The moving assembly is used to remove the top cover 15. The moving assembly includes two U-shaped frames 11 fixedly connected to the top of the U-shaped plate 4 and a lifting trough plate 12. Vertical slots are formed on both sides of the inner wall of the U-shaped frame 11. A threaded rod 13 is installed inside the right vertical slot. A rotary motor is fixedly connected to the top of the threaded rod 13, and the rotary motor is mounted on the top of the U-shaped frame 11. An adjusting screw 14 is installed inside the lifting trough plate 12. A moving motor is fixedly connected to one end of the adjusting screw 14. A support base is installed at the bottom of the moving motor, and the surface of the support base is fixedly connected to the surface of the lifting trough plate 12 to ensure the normal operation of the moving motor. A moving block is threadedly connected to the surface of the adjusting screw 14. A top cover 15 is fixedly connected to the bottom, and a stirring rod 16 is rotatably connected to the bottom of the top cover 15. Support rods are fixedly connected to the surface of the stirring rod 16 at equal intervals.

[0030] The implementation principle of the reactive polyurethane hot melt adhesive production equipment for edge sealing in this application embodiment is as follows: When the device is in use, the material and liquid are introduced into the interior of the mixing drum 5 through the feed pipe. The drive motor is started, so that the output shaft of the drive motor drives the cam 2 to rotate, thereby causing the U-shaped frame 3 to move back and forth continuously through the connecting strip and the U-shaped plate 4. During this process, the connecting gear 9 is reciprocated by the meshing action of the fixed tooth plate 10, thereby causing the rotating rod 8 to reciprocate with the square sleeve 6. Under the action of the square block 17, the stirring rod 16 reciprocates, so that the liquid in the mixing drum 5 first moves in one direction. When the stirring rod 16 changes direction, the material continues to rotate under the action of inertia, so that the contact between the stirring rod 16 and the material is more sufficient, thereby improving the mixing uniformity of the device.

[0031] After mixing, the device needs to be cleaned. Start the rotary motor to rotate the threaded rod 13. Under the action of the lifting block 18, the lifting trough plate 12 moves vertically, causing the top cover 15 to move upward and the stirring rod 16 to disengage from the stirring drum 5. Then start the moving motor to rotate the adjusting screw 14, causing the moving block to move the top cover 15 along with the stirring drum 5, thus misaligning the top cover 15 and the stirring drum 5. This facilitates separate cleaning of the stirring rod 16 and the stirring drum 5, making the cleaning of the device more thorough. After cleaning, start the rotary motor and the moving motor to reset the top cover 15, allowing the square block 17 to be reinserted into the square sleeve 6, making the closure of the device easier.
