Description

Technical Field

[0001] This utility model relates to a filling device, specifically a polyurethane resin filling device, belonging to the technical field of liquid coating filling devices. Background Technology

[0002] Polyurethane resin is a type of high molecular weight polymer with urethane groups in its main chain. It is synthesized by polycondensation reaction of isocyanate and polyol. It has adjustable physicochemical properties and is widely used in the coatings industry. During the production process, polyurethane resin needs to be filled into the filling tank by a coating filling machine.

[0003] However, during the process of polyurethane resin flowing from the filling head into the filling tank, the filling tank is in an open state. Due to the large diameter of the tank opening, items may fall into the filling tank during the filling process, thus contaminating the polyurethane resin. Furthermore, items that fall into the filling tank are inconvenient to remove, and even if removed, they will also become contaminated. In addition, the filling tank is usually placed manually at the bottom of the filling head, and the manual placement may result in deviations. When the deviation is large, it is easy to cause polyurethane resin to spill, thus wasting polyurethane resin and contaminating the filling machine. Utility Model Content

[0004] The purpose of this invention is to provide a polyurethane resin filling device to solve the above-mentioned problems. It can block the opening of the filling tank to a certain extent during the process of polyurethane resin flowing from the filling head into the filling tank, thereby preventing objects from falling into the filling tank. It can also achieve precise positioning of the filling tank during the filling process to avoid polyurethane resin leakage caused by positional deviation of the filling tank.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a polyurethane resin filling device, including a filling machine body, on which multiple conveying rollers are installed, a shield is fixedly connected to the filling machine body, and a positioning structure is provided on the shield. The positioning structure includes guide seats and a movable frame. Two guide seats are fixedly connected to the shield, and the same movable frame is slidably connected to the two guide seats. Four racks are fixedly connected to the movable frame, and four connecting shafts are rotatably connected to the shield. A stop bar is fixedly connected to the bottom of each connecting shaft, and a gear is fixedly connected to the connecting shaft. The gear meshes with the adjacent rack. An electric push rod is installed on the shield, and the extended end of the electric push rod is fixedly connected to the movable frame.

[0006] Preferably, the movable frame has an overall "I" shaped structure, and the two adjacent stops have a V-shaped structure.

[0007] Preferably, a material pump is installed on the filling machine body, a filling head is installed on the filling machine body, a material conveying pipe is fixedly connected between the filling head and the material pump, and a solenoid valve is installed on the filling head.

[0008] Preferably, the bottom end of the injection head extends into the interior of the shield, and the shield is provided with a material receiving structure.

[0009] Preferably, the receiving structure includes a rotating shaft and a connecting rod. The rotating shaft is rotatably connected to the shield, and the connecting rod is fixedly connected to the rotating shaft. One end of the connecting rod is fixedly connected to a support plate, and a receiving box is engaged on the support plate.

[0010] Preferably, a motor is mounted on the shield, and the output shaft of the motor is fixedly connected to the top end of the rotating shaft.

[0011] Preferably, the receiving box is located directly below the filling head, and the top of the outer side of the receiving box has an outwardly extending protrusion.

[0012] Preferably, a cylinder is installed on the filling machine body, and a pressure plate is fixedly connected to the bottom end of the cylinder.

[0013] Preferably, a connecting frame is fixedly connected to the filling machine body, and multiple conveying shafts are rotatably connected to the connecting frame, which is inclined.

[0014] The beneficial effects of this utility model are as follows: During the filling process, the opening of the filling barrel can be blocked by the shield, thereby preventing objects from falling into the filling barrel and making it more convenient to use. At the same time, during the filling process, the filling barrel can be blocked by two adjacent baffles. Since the two adjacent baffles are V-shaped, the cylindrical filling barrel can be positioned, preventing the filling barrel from shifting and causing polyurethane resin to spill during the filling process. After filling is completed, the electric push rod can be activated. The electric push rod extends and drives the moving frame to move. The two guide seats can guide the movement of the moving frame. The movement of the moving frame will drive the four racks to move. The racks drive the gears to rotate. The rotation of the gears will drive the connecting shaft to rotate. The connecting shaft will drive the baffles to move away from the filling barrel. When the minimum distance between the two baffles is greater than the diameter of the filling barrel, multiple rotating conveyor rollers will drive the filling barrel to move, thereby facilitating the quick release of the positioning of the filling barrel and facilitating the subsequent capping process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a polyurethane resin filling device includes a filling machine body 1, on which multiple conveying rollers 2 are installed. A shield 3 is fixedly connected to the filling machine body 1. A positioning structure 4 is provided on the shield 3. The positioning structure 4 includes a guide seat 401 and a moving frame 402. Two guide seats 401 are fixedly connected to the shield 3. The same moving frame 402 is slidably connected to the two guide seats 401. The moving frame 402 is generally in the shape of an "I". Four racks 404 are fixedly connected to the moving frame 402. Four connecting shafts 406 are rotatably connected to the shield 3. A stop bar 407 is fixedly connected to the connecting shaft 406 near the bottom. A gear 405 is fixedly connected to the connecting shaft 406. The gear 405 meshes with the adjacent rack 404. An electric push rod 403 is installed on the shield 3. The extended end of the electric push rod 403 is fixedly connected to the moving frame 402.

[0024] As a technical optimization solution of this utility model, such as Figure 5 As shown, the two adjacent stop bars 407 form a V-shaped structure, so when the cylindrical filling barrel simultaneously abuts against the two adjacent stop bars 407, the filling barrel can be accurately positioned by the two stop bars 407.

[0025] As a technical optimization solution of this utility model, such as Figure 1 and Figure 3 As shown, a material pump 6 is installed on the filling machine body 1, which can extract polyurethane resin raw materials. A filling head 8 is installed on the filling machine body 1, and the bottom end of the filling head 8 extends into the interior of the shield 3. The filling head 8 allows polyurethane resin to flow into the interior of the filling tank for collection. A conveying pipe 7 is fixedly connected between the filling head 8 and the material pump 6, which can realize the conveying of polyurethane resin. A solenoid valve 9 is installed on the filling head 8. By closing the solenoid valve 9, the dripping amount of polyurethane resin can be reduced.

[0026] As a technical optimization solution of this utility model, such as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the shield 3 is provided with a material receiving structure 5, which includes a rotating shaft 501 and a connecting rod 502. The rotating shaft 501 is rotatably connected to the shield 3, and the connecting rod 502 is fixedly connected to the rotating shaft 501. One end of the connecting rod 502 is fixedly connected to a support plate 503, and a material receiving box 504 is engaged on the support plate 503. The material receiving box 504 is located directly below the filling head 8. When the solenoid valve 9 is closed, the material receiving box 504 can move to the bottom of the filling head 8, thereby preventing the polyurethane resin inside the filling head 8 from dripping onto the filling machine body 1 and avoiding contamination of the filling machine body 1.

[0027] As a technical optimization solution of this utility model, such as Figure 3 and Figure 5 As shown, a motor 505 is installed on the shield 3. Driven by the motor 505, the receiving box 504 can be quickly positioned at the bottom of the filling head 8 or quickly deviated from the bottom of the filling head 8.

[0028] As a technical optimization solution of this utility model, such as Figure 6 As shown, the top of the outer side of the receiving box 504 is provided with an outwardly extending protrusion, so that the receiving box 504 can be easily removed from the tray 503, thereby facilitating the pouring of the polyurethane resin collected inside.

[0029] As a technical optimization solution of this utility model, such as Figure 3 and Figure 4 As shown, a cylinder 10 is installed on the filling machine body 1, and a pressure plate 11 is fixedly connected to the bottom end of the cylinder 10. Therefore, the cylinder 10 can drive the pressure plate 11 to press the lid onto the filling barrel, thereby achieving a seal on the filling barrel.

[0030] As a technical optimization solution of this utility model, such as Figure 3 and Figure 4 As shown, a connecting frame 12 is fixedly connected to the filling machine body 1, and multiple conveying shafts 13 are rotatably connected to the connecting frame 12. The connecting frame 12 is inclined, so that the sealed filling barrel automatically moves to the ground, thereby facilitating the subsequent transfer of the filling barrel.

[0031] In use, this invention allows the filling barrel to be placed on the rotating conveyor roller 2. The conveyor roller 2 then drives the filling barrel to move until it simultaneously contacts two of the stop bars 407. Because the two adjacent stop bars 407 form a V-shape, the cylindrical filling barrel can be positioned, preventing leakage of polyurethane resin during filling due to barrel misalignment. The inlet of the pump 6 can be connected to the polyurethane resin storage device via a connecting pipe. When filling is required, the solenoid valve 9 can be opened, and then the pump 6 can be started, allowing the polyurethane resin to enter the conveying pipe 7 and finally flow from the filling head 8 into the filling barrel. During the process of filling the filling head 8, the opening of the filling head 8 can be blocked by the shield 3 to prevent objects from falling into the filling head 8, thus making it easier to use. After filling is completed, the pump 6 can be turned off first, then the solenoid valve 9 can be turned off, and then the motor 505 can be started. The output shaft of the motor 505 rotates, which drives the rotating shaft 501 to rotate. The rotation of the rotating shaft 501 drives the connecting rod 502 to rotate. The rotation of the connecting rod 502 drives the pallet 503 to move. The pallet 503 drives the receiving box 504 to move towards the filling head 8. When the receiving box 504 is directly below the filling head 8, the output shaft of the motor 505 stops rotating. Therefore, when polyurethane resin drips from the filling head 8, it can pass through the receiving box. 504 is used to receive the material, preventing the polyurethane resin inside the filling head 8 from dripping onto the filling machine after the filling barrel deviates from the bottom, thus avoiding contamination of the filling machine. After filling is completed, the electric push rod 403 can be activated. The electric push rod 403 extends and drives the moving frame 402 to move. Two guide seats 401 are set to guide the movement of the moving frame 402. The movement of the moving frame 402 will drive the four racks 404 to move. The racks 404 drive the gears 405 to rotate. The rotation of the gears 405 will drive the connecting shaft 406 to rotate. The connecting shaft 406 will drive the stop rod 407 to move away from the filling barrel. When the minimum distance between the two stop rods 407 is greater than the diameter of the filling barrel, multiple rotating conveyors... The feeding roller 2 drives the filling barrel to move. Then, the electric push rod 403 retracts to reset the four stop rods 407. Next, during the movement, the filling barrel will contact the other two stop rods 407. At this time, the filling barrel is located directly below the pressure plate 11. Then, the barrel cover is placed on the top of the filling barrel. By activating the cylinder 10, the cylinder 10 extends and drives the pressure plate 11 to move towards the filling barrel, pressing the barrel cover tightly on the top of the filling barrel, thereby achieving a seal on the filling barrel. After the next filling is completed, the four stop rods 407 will open simultaneously. Then, the sealed filling barrel will continue to move to multiple conveyor shafts 13. Finally, under the action of gravity, it will move from multiple conveyor shafts 13 to the ground, thus completing the polyurethane resin filling work.
