Technical Field
[0001] This invention relates to the field of automotive parts technology, specifically to a production apparatus for polyurethane toughened epoxy resin reinforcing films used in automobiles. Background Technology
[0002] Reinforcing film, also known as thin steel plate reinforcement, is composed of a backing (fiber-reinforced cloth or felt, aluminum foil, etc.) and a sheet adhesive (with epoxy resin as the main material). It has specified shape and size requirements and is firmly bonded to the inner side of the outer panel of the car body or component after being heated and cured, thus reinforcing the outer panel.
[0003] In the production process of reinforcing films, a mixing device is usually required. Traditional mixing devices generally require the materials to be weighed in advance as needed and then added one by one. When there is a large amount of liquid, it is necessary to weigh and add it repeatedly, which is inconvenient. Therefore, a production device for polyurethane toughened epoxy resin reinforcing films for automobiles is proposed to solve the above-mentioned problems. Summary of the Invention

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0036] In the embodiments, by Figure 1-6 The present invention provides a production apparatus for polyurethane toughened epoxy resin reinforcing film for automobiles. The invention includes a mixing device housing 1, a colloidal material feeding pipe 2 connected to the top of the mixing device housing 1, a liquid material metering feeding component 3 installed on the top of the mixing device housing 1, a stirring device 4 extending into the mixing device housing 1 fixedly installed on the outside of the mixing device housing 1, a tray 5 rotatably connected to the bottom of the mixing device housing 1, and a buckle 6 connected to the mixing device housing 1 on the other side fixedly installed on the left side of the tray 5.
[0037] A sealing hole located inside the mixing device housing 1 is provided on the top of the mixing device housing 1.
[0038] The liquid material metering and dispensing component 3 includes a fixing plate 31 fixed to the top of the mixing device housing 1. A U-shaped adjusting plate 32 is slidably connected to the outside of the fixing plate 31 and is slidably connected to the top of the mixing device housing 1. An L-shaped sealing sliding block 33 is slidably connected to the inside of the fixing plate 31. An operating rod 34 is rotatably connected to the inside of the U-shaped adjusting plate 32 via a threaded connection to the inside of the L-shaped sealing sliding block 33. A sealing pad 35 is fixedly installed at the bottom of the L-shaped sealing sliding block 33. A discharge valve 36 is connected to the right side of the U-shaped adjusting plate 32.
[0039] Specifically, a sealing gasket is provided between the U-shaped adjusting plate 32 and the top of the mixing device housing 1 and the outside of the fixing plate 31. The outside of the U-shaped adjusting plate 32 is provided with scale lines, and different scale lines correspond to different ranges and internal volumes.
[0040] The stirring device 4 includes a stirring rod 401 that is rotatably connected to the mixing device housing 1. A power motor 402 is fixedly installed on the outside of the mixing device housing 1. The output end of the power motor 402 is connected to a transmission box 403 that is connected to the stirring rod 401.
[0041] During normal mixing, the power motor 402 generates power and drives the mixing rod 401 to rotate through the transmission box 403, thereby mixing the materials in the mixing device.
[0042] Specifically, stirring blades are provided on the outside of the stirring rod 401.
[0043] The other end of the stirring rod 401 connected to the transmission box 403 is provided with a heating groove, and the end of the heating groove is stepped.
[0044] The stirring device 4 also includes a heating component 41, which includes a locking seat 411 fixed to the outside of the mixing device housing 1, and a heating rod 412 extending into the heating tank is engaged on the inner side of the locking seat 411.
[0045] The heating rod 412 has a cleaning block connected to its end and a friction plate fixedly connected to its exterior.
[0046] Specifically, the cleaning block is provided with bristles on the outside, and the cleaning block and its external bristles do not come into contact with the inner wall when it is in the heating tank.
[0047] The heating assembly 41 also includes an induction heating coil 413 fixed to the outside of the mixing device housing 1, and the induction heating coil 413 is sleeved on the outside of the heating rod 412.
[0048] When heating is required, the stirring rod 401 is heated by the induction heating coil 413, and the heat at its end can be transferred to other positions. At the same time, due to the friction between the friction plate and the inner wall of the heating tank, the stirring rod 401 obtains a better heating effect.
[0049] The locking seat 411 includes a C-shaped seat fixed to the outside of the mixing device housing 1. A spring is fixedly installed on the outside of the C-shaped seat, and a locking rod extending into the heating rod 412 is fixedly connected to the other end of the spring.
[0050] After heating is complete, when maintenance is required on the heating rod 412, the locking rod can be pulled up to remove it from the heating rod 412. At this time, the heating rod 412 can slide freely and thus detach from the stirring rod 401. During the movement, the cleaning block can easily clean the inner wall of the heating tank.
[0051] The pallet 5 is equipped with a sealing gasket on its top, and the mixing device housing 1 is equipped with a Hall sensor that is adapted to the position of the pallet 5.
[0052] The stirring device 4 is equipped with a controller, and the Hall sensor is electrically connected to the controller.
[0053] Working principle:
[0054] When adding materials, first close the tray 5 with the buckle 6, then add solid materials through the colloidal material dispensing pipe 2, and then add liquid materials through the liquid material metering dispensing component 3 in the order of the liquid materials to be added.
[0055] During the feeding process, first turn the operating lever 34 to move the U-shaped adjusting plate 32. At the same time, observe the scale line to confirm the volume of the space formed between the U-shaped adjusting plate 32 and the fixed plate 31. At this time, the amount of material added to the inside can be confirmed according to the feeding amount. If too much material is added, it can be discharged directly through the discharge valve 36 until the feeding amount is appropriate.
[0056] After confirming the feeding amount, the operating lever 34 can be pulled upwards to move the L-shaped sealing sliding block 33 upwards, allowing the internal liquid to directly enter the mixing device housing 1 through the sealing hole, completing the feeding operation. Then, the next liquid material can be added. This feeding method eliminates the need to pour the liquid from the container into the device, making it more convenient.
[0057] After all materials have been added, the stirring device 4 can be started to stir the inside, while the heating component 41 heats the inside to maintain a good processing condition.
