Description

Technical Field

[0001] This utility model relates to the field of polyurethane adhesive production technology, and in particular to a polyurethane adhesive filling equipment. Background Technology

[0002] Polyurethane adhesives are adhesives whose molecular chains contain urethane or isocyanate groups. They have extremely high polarity and reactivity, and can form excellent chemical adhesion with substrates containing active hydrogen. Polyurethane adhesives have excellent impact resistance, flexibility, abrasion resistance and low-temperature resistance. They can cure at room temperature or under heating conditions, and have a wide range of applications. They come in various types, including solvent-based, solvent-free and water-based, to meet the needs of different industries.

[0003] With the continuous growth in market demand for polyurethane adhesives, the filling process, as a key step in the production process, is placing increasingly higher demands on equipment. However, due to the inherent viscosity of polyurethane adhesives, sedimentation or stratification can easily occur during storage, leading to uneven adhesive composition in different areas and affecting product quality and performance stability. Furthermore, some adhesive adheres to the inner wall of the storage tank during filling, and long-term accumulation not only wastes raw materials but also increases cleaning difficulty and impacts production efficiency. In addition, existing filling equipment typically uses a fixed connection for the filling head, which cannot ensure accurate injection of adhesive into containers of different heights and shapes, resulting in filling deviations.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1:

[0030] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a polyurethane adhesive filling device, including a workbench 1, a frame 2 installed on the top of the workbench 1, a material conveying component 3 arranged inside the frame 2, a support 4 fixed on the top of the workbench 1, a storage tank 5 fixed inside the support 4, and a stirring assembly 6 arranged inside the storage tank 5.

[0031] The workbench 1 serves as the supporting foundation for the entire equipment, providing a stable mounting platform for the frame 2, support 4, uprights 7, and cylinder 12, ensuring the stability of the equipment during operation. The frame 2 is used to install the conveying component 3, providing structural support for it and ensuring its stable operation. The conveying component 3, through its internal structure, can transport containers to designated locations for filling. The support 4 is used to fix the storage tank 5, providing stable support for it. The storage tank 5 is used to store polyurethane adhesive raw materials. The stirring component 6 can rotate under the drive of the second motor 21 to stir the polyurethane adhesive in the storage tank 5 and scrape off the polyurethane adhesive adhering to the inner wall of the storage tank 5, thereby improving the mixing quality of the polyurethane adhesive.

[0032] Two sets of uprights 7 are fixed on the top of the workbench 1. A movable frame 8 is slidably connected to the outside of the uprights 7. A filling pipe 9 is installed inside the movable frame 8 through a fixing ring. A material conveying groove 10 is opened on the inner wall of the filling pipe 9. Two sets of feed pipes 11 with upper and lower designs are connected to the outside of the filling pipe 9.

[0033] The upright 7 provides a sliding track for the movable frame 8, allowing the movable frame 8 to slide up and down along the upright 7, thereby realizing the lifting and lowering movement of the filling tube 9 to meet the filling needs of different heights. The movable frame 8 is set to provide stable support for the filling tube 9, ensuring the stability of the filling tube 9 during the filling process. At the same time, it can lift and lower the filling tube 9 with the drive of the cylinder 12, adjusting the distance between the filling tube 9 and the container to ensure the smooth progress of the filling operation. The material conveying groove 10 on the inner wall of the filling tube 9 can provide a flow channel for the polyurethane adhesive, allowing the adhesive to flow smoothly from the feed pipe 11 and flow out through the filling tube 9 for filling. At the same time, the feed pipe 11 on the outside of the filling tube 9 can transport the polyurethane adhesive drawn from the storage tank 5 by the feed pump 14 into the filling tube 9 to provide material for filling.

[0034] The stirring assembly 6 includes a stirring rod 61 disposed inside the storage tank 5. A stirring blade 62 and a scraper 63 are fixed to the outer side of the stirring rod 61, and the outer side of the scraper 63 is in contact with the inner wall of the storage tank 5.

[0035] The stirring rod 61 can rotate under the drive of the second motor 21, which in turn drives the stirring blade 62 and the scraper 63 to rotate. The stirring blade 62 is set to stir the polyurethane adhesive in the storage tank 5, so that the adhesive is mixed evenly, preventing sedimentation or stratification, and ensuring the quality stability of the adhesive. The scraper 63 can scrape off the adhesive adhering to the inner wall of the storage tank 5 during the stirring process, preventing the adhesive from accumulating and clumping on the tank wall, and at the same time helping to improve the stirring effect.

[0036] Example 2:

[0037] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, a cylinder 12 is installed on the top of the workbench 1, and a push block 13 is fixed on the outside of the movable frame 8. The bottom of the push block 13 is fixedly connected to the piston rod of the cylinder 12 through a flange.

[0039] The cylinder 12, through the extension and retraction of its piston rod, can push the push block 13 to move up and down, thereby causing the movable frame 8 and the filling tube 9 to slide up and down along the upright 7, realizing the lifting and lowering control of the filling tube 9 to meet the filling requirements of different heights. The push block 13 is set to transmit the power of the cylinder 12 to the movable frame 8, so that the movable frame 8 can move up and down with the movement of the piston rod of the cylinder 12. It should be noted that the cylinder 12 is used in conjunction with an air compressor, an air tank, a filter pressure reducing valve, a directional control valve, and a flow control valve. During use, the air compressor compresses the ambient air to a set pressure and stores it in the air tank. The filter pressure reducing valve further purifies the air and stabilizes the pressure, and delivers it to the control valve through the air pipe. The directional control valve switches the airflow channel according to the electrical signal to determine the extension and retraction direction of the cylinder 12. The flow control valve adjusts the airflow speed and controls the movement speed of the cylinder 12. Compressed air enters the rod chamber or rodless chamber of the cylinder 12, pushing the piston to move. The piston drives the piston rod to output linear reciprocating motion.

[0040] Specifically, a feed pump 14 is installed inside the bracket 4. The feed end of the feed pump 14 is connected to a guide pipe 15, and the other end of the guide pipe 15 is connected to the bottom of the storage tank 5. The discharge end of the feed pump 14 is connected to a hose 16, and the other end of the hose 16 is connected to one end of the feed pipe 11 through a flange.

[0041] The feed pump 14 is configured to extract the polyurethane adhesive from the storage tank 5 through the feed pipe 15 and deliver it through the hose 16 to the feed pipe 11 of the filling pipe 9, providing a continuous material supply for the filling operation. The feed pipe 15 is configured to guide the polyurethane adhesive from the storage tank 5 to the feed pump 14. The hose 16 has a certain degree of flexibility, which can keep the material conveying smooth when the movable frame 8 moves up and down, and at the same time can deliver the polyurethane adhesive extracted by the feed pump 14 to the filling pipe 9.

[0042] Specifically, a tank cover 17 is installed on the top of the storage tank 5 via a connecting flange. The top of the tank cover 17 is connected to a feed hopper 18. A sealing cover 19 is hinged to the top of the feed hopper 18 via a hinge, and a handle is fixed to the outside of the sealing cover 19.

[0043] The lid 17 is designed to seal the storage tank 5, preventing external impurities from entering the storage tank 5 and contaminating the polyurethane adhesive. The feed hopper 18 serves as the inlet for adding polyurethane adhesive raw materials. The sealing cover 19 is designed to seal the feed hopper 18, preventing polyurethane adhesive from leaking from the feed hopper 18 during equipment operation. The handle on its outer side allows operators to easily open and close the sealing cover 19.

[0044] Specifically, a fixing frame 20 is fixed to the top of the can lid 17, and a second motor 21 is installed inside the fixing frame 20. A transmission rod 22 is fixed to the output end of the second motor 21, and the bottom end of the transmission rod 22 is fixedly connected to the top end of the stirring rod 61 through a flange.

[0045] The fixing frame 20 is used to fix the second motor 21 and provide a stable installation position for the second motor 21. The second motor 21 is used to provide power to the stirring assembly 6 to stir the polyurethane adhesive in the storage tank 5. The transmission rod 22 is used to transmit the power of the second motor 21 to the stirring rod 61, which drives the stirring rod 61 to rotate and realize the stirring function.

[0046] Example 3:

[0047] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0048] Specifically, the material conveying component 3 includes a first motor 31 installed on the outside of the frame 2, two sets of transmission rollers 32 rotatably connected to the inner wall of the frame 2, and one end of the transmission rollers 32 is fixedly connected to the output end of the first motor 31. A conveyor belt 33 is connected to the outside of the transmission rollers 32, and a guide plate 34 is provided above the conveyor belt 33.

[0049] The first motor 31 is configured to provide power to the transmission roller 32, driving the transmission roller 32 to rotate. The transmission roller 32 can rotate under the drive of the first motor 31, and drive the conveyor belt 33 to circulate through the friction with the conveyor belt 33. The conveyor belt 33 serves as a material carrier and conveying component, used to transport the container from the starting position to the filling position, completing the material conveying task. The guide plate 34 is configured to guide the movement direction of the container on the conveyor belt 33, ensuring that the container can reach the filling position and preventing the container from deviating from the track during the conveying process.

[0050] Specifically, an L-shaped plate 23 is fixed on the outer side of the frame 2, an mounting cylinder 24 is provided on the top of the L-shaped plate 23, a sliding groove 25 is provided on the inner wall of the L-shaped plate 23, and the outer side of the mounting cylinder 24 is slidably connected to the inner wall of the sliding groove 25.

[0051] The L-shaped plate 23 is provided to provide an installation position for the mounting cylinder 24. The mounting cylinder 24 slides in the groove 25 of the L-shaped plate 23 and is connected to the tie rod 26 by the fixing bolt 27. It is used to adjust the height and angle of the guide plate 34 to adapt to the conveying and filling needs of containers of different sizes. The groove 25 is provided to provide a sliding track for the mounting cylinder 24, so that the mounting cylinder 24 can slide up and down along the groove 25, thereby realizing the adjustment of the position of the guide plate 34.

[0052] Specifically, a pull rod 26 is installed on one side of the guide plate 34, a fixing bolt 27 is slidably connected to the inner wall of the mounting cylinder 24, and the bottom end of the fixing bolt 27 is slidably connected to the outer side of the pull rod 26 through a fixing ring. A knob 28 is provided on the top of the mounting cylinder 24, and the inner wall of the knob 28 is threadedly connected to the outer side of the fixing bolt 27.

[0053] The pull rod 26 can adjust the position of the guide plate 34 when the mounting cylinder 24 moves left and right, guiding the container to the filling position. By tightening or loosening the knob 28, the relative position of the mounting cylinder 24 and the pull rod 26 can be fixed or adjusted, thereby achieving the fixing and adjustment of the position of the guide plate 34.

[0054] Working Principle: When using this polyurethane adhesive filling equipment, the polyurethane adhesive raw material is first added to the storage tank 5 through the feed hopper 18. After addition, the sealing cap 19 is closed to prevent leakage. Next, the second motor 21 is started, driving the transmission rod 22 to rotate, which in turn drives the stirring rod 61 to rotate. The stirring blades 62 on the stirring rod 61 stir the polyurethane adhesive in the storage tank 5, ensuring uniform mixing. Simultaneously, the scraper 63 scrapes off the adhesive adhering to the inner wall of the storage tank 5 to prevent clumping and improve the stirring effect. At the same time, the first motor 31 is started, driving the transmission roller 32 to rotate. The transmission roller 32 drives the conveyor belt 33 in a cyclical motion, transporting the container to be filled from the starting position to the filling position via the guide plate 3. 4 can guide the movement direction of the container on the conveyor belt 33 to ensure that the container reaches the filling position. If the container size is different, the position of the mounting cylinder 24 in the slide groove 25 of the L-shaped plate 23 can be adjusted, and the position of the guide plate 34 can be fixed or adjusted by using the fixing bolt 27 and the knob 28. When the container reaches the filling position, the cylinder 12 is started. The piston rod of the cylinder 12 extends and retracts, pushing the push block 13 to move up and down, driving the movable frame 8 and the filling tube 9 to slide up and down along the upright 7 to adjust the distance between the filling tube 9 and the container. Then the conveying pump 14 is started. The conveying pump 14 extracts the polyurethane adhesive in the storage tank 5 through the guide pipe 15 and delivers it to the feed pipe 11 of the filling tube 9 through the hose 16. The adhesive flows out through the conveying groove 10 on the inner wall of the filling tube 9 to complete the filling of the container.
