Description

Technical Field

[0001] This utility model relates to the technical field of silicon steel sheet coating machine, specifically to a uniform adhesive application mechanism for a silicon steel sheet coating machine. Background Technology

[0002] The stator core is a crucial component of the stator and a major part of the motor's magnetic circuit. Currently, by coating the surface of silicon steel sheets with a self-adhesive coating, and then hot-pressing the stacked stator core blanks using a hot press, the self-adhesive coating on the silicon steel sheet surface melts. After the hot-pressed stator core blank is removed and the melted self-adhesive coating cools, the adjacent silicon steel sheets can be bonded together.

[0003] Silicon steel sheets are core components in equipment such as motors and transformers, and the quality of their lamination and bonding directly affects product performance. Existing silicon steel sheet coating machines often experience coating deviations due to mechanical vibration or insecure positioning of the silicon steel sheets during operation. For example, if oriented silicon steel sheets are not securely fixed, they are prone to shaking with equipment vibration, leading to deviations in coating position and uneven adhesive layers. Misalignment can also occur during silicon steel sheet lamination, further exacerbating uneven coating and even causing workpiece scrap. Therefore, a uniform adhesive application mechanism for a silicon steel sheet coating machine is proposed to address the aforementioned problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A uniform adhesive application mechanism for a silicon steel sheet coating machine includes a conveying device, a gantry frame disposed on top of the conveying device, and an adhesive application device disposed on top of the gantry frame and extending to its bottom. The conveying device includes a base, a conveyor belt rotatably connected inside the base, and a drive motor fixedly installed outside the base for driving the conveyor belt. A limiting mechanism for limiting and guiding the silicon steel sheet is provided outside the base. An air blowing structure is provided on the surface of the conveyor belt to flatten the adhesive layer using airflow pressure.

[0007] The limiting mechanism includes an electric push rod fixedly installed outside the machine base, a connecting frame fixedly connected to the output end of the electric push rod, and a limiting wheel rotatably connected inside the connecting frame;

[0008] The air blowing structure includes a connecting plate fixedly connected to the inner wall of the base and a piston cylinder fixedly connected to the outside of the base.

[0009] Furthermore, there are multiple limiting wheels, which are distributed at equal intervals inside the connecting frame.

[0010] Furthermore, the number of limiting mechanisms is two sets, and the two sets of limiting mechanisms are symmetrically distributed on the top of the base.

[0011] Furthermore, the piston cylinder is fixedly connected to both the delivery pipe and the air inlet pipe via check valves, and the nozzle is fixedly connected to the outside of the spray pipe via an inclined nozzle.

[0012] Furthermore, a piston rod extending to the surface of the piston cylinder is fixedly connected to the top of the piston plate, and a transmission plate is fixedly connected to the top of the piston rod.

[0013] Furthermore, a buffer spring is fixedly connected between the piston cylinder and the transmission plate, and the buffer spring is connected to the outside of the piston rod.

[0014] Furthermore, the glue application device includes a glue storage tank fixedly connected to the top of the gantry, a delivery pump, and a mounting frame disposed on the lower surface of the gantry.

[0016] Compared with the prior art, this utility model provides a uniform adhesive application mechanism for a silicon steel sheet coating machine, which has the following beneficial effects:

[0017] 1. The uniform gluing mechanism of this silicon steel sheet coating machine achieves continuous conveying of silicon steel sheets through a conveyor belt driven by a drive motor. Two sets of left and right symmetrical limiting mechanisms push the connecting frame through electric push rods, so that multiple equally spaced limiting wheels form rolling limiting on the silicon steel sheets from both sides. This can not only adapt to silicon steel sheets of different widths, but also reduce friction and avoid conveying deviation. Together with the gluing device on the gantry, it ensures that the gluing tube is aligned with the preset area of ​​the silicon steel sheet, solving the problem of gluing misalignment caused by vibration or poor positioning.

[0018] 2. The uniform adhesive application mechanism of this silicon steel sheet coating machine, when the mounting frame and the coating pipe are raised and lowered by the telescopic cylinder for adhesive application, the mounting frame simultaneously drives the transmission plate of the air blowing structure, so that the piston rod pushes the piston plate to compress the gas in the piston cylinder, and blows it out from the inclined nozzle of the spray pipe through the conveying pipe. The airflow immediately spreads the adhesive layer, and the buffer spring reduces the impact of the piston plate movement, which not only improves the uniformity of adhesive application, but also improves the production efficiency through continuous conveying.

[0023] 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.

[0024] Please see Figures 1 to 3 The uniform adhesive application mechanism of a silicon steel sheet coating machine in this embodiment includes a conveying device 1, a gantry frame 2 set on the top of the conveying device 1, and an adhesive application device 3 set on the top of the gantry frame 2 and extending to its bottom. The conveying device 1 includes a base 11, a conveyor belt 12 rotatably connected inside the base 11, and a drive motor 13 fixedly installed outside the base 11 for driving the conveyor belt 12. A limiting mechanism 4 for limiting and guiding the silicon steel sheet is provided outside the base 11. An air blowing structure 5 is provided on the surface of the conveyor belt 12 to flatten the adhesive layer using airflow pressure.

[0025] The limiting mechanism 4 includes an electric push rod 41 fixedly installed outside the base 11. A connecting frame 42 is fixedly connected to the output end of the electric push rod 41, and a limiting wheel 43 is rotatably connected inside the connecting frame 42. By driving the connecting frame 42 with the electric push rod 41, the internally rotatably connected limiting wheel 43 comes into contact with the silicon steel sheet. The distance between the limiting wheel 43 and the silicon steel sheet can be flexibly adjusted to adapt to silicon steel sheets of different widths. The rotational setting of the limiting wheel 43 can reduce friction with the silicon steel sheet and avoid scratching the material.

[0026] Specifically, there are multiple limit wheels 43, which are distributed at equal intervals inside the connecting frame 42.

[0027] It should be noted that there are two sets of limiting mechanisms 4, which are symmetrically distributed on the top of the base 11. The symmetrical distribution of the two sets of limiting mechanisms 4 on the top of the base 11 can effectively counteract the offset caused by equipment vibration, ensuring that the silicon steel sheet remains centered during the conveying process, and providing a stable reference position for subsequent glue application.

[0028] In this embodiment, the air blowing structure 5 includes a connecting plate 51 fixedly connected to the inner wall of the base 11 and a piston cylinder 53 fixedly connected to the outside of the base 11. A nozzle 52 is fixedly connected to the outside of the connecting plate 51, a piston plate 54 is slidably connected inside the piston cylinder 53, a delivery pipe 58 is fixedly connected between the piston cylinder 53 and the nozzle 52, and an air inlet pipe 59 is fixedly connected to the bottom end of the piston cylinder 53.

[0029] The piston cylinder 53 is fixedly connected to the delivery pipe 58 and the air inlet pipe 59, respectively, and the nozzle 52 is fixedly connected to the outside of the nozzle.

[0030] Specifically, a piston rod 55 extending to the surface of the piston cylinder 53 is fixedly connected to the top of the piston plate 54, and a transmission plate 56 is fixedly connected to the top of the piston rod 55.

[0031] It should be noted that a buffer spring 57 is fixedly connected between the piston cylinder 53 and the transmission plate 56, and the buffer spring 57 is connected to the outside of the piston rod 55. By setting the buffer spring 57, a buffering effect is played during the movement of the piston plate 54, so as to avoid the piston plate 54 moving too fast or too violently, which would cause unstable airflow, make the airflow spray more stable, further improve the quality of blowing and spreading the adhesive layer, and ensure the uniformity of adhesive application.

[0032] In this embodiment, the glue application device 3 includes a glue storage tank 31 fixedly connected to the top of the gantry frame 2, a delivery pump 32, and a mounting frame 33 disposed on the lower surface of the gantry frame 2. A glue application tube 34 is fixedly connected inside the mounting frame 33. A telescopic cylinder 35 is fixedly installed on the top of the gantry frame 2. The mounting frame 33 is fixedly connected to the output end of the telescopic cylinder 35. The end of the transmission plate 56 away from the piston rod 55 is fixedly connected to the outside of the mounting frame 33. The telescopic cylinder 35 drives the mounting frame 33 to raise and lower the glue application tube 34. The connection between the transmission plate 56 and the mounting frame 33 enables the linkage between glue application and air blowing. The telescopic cylinder 35 can precisely control the height of the glue application tube 34, ensuring uniform glue application. The linkage between glue application and air blowing allows for immediate glue evenness treatment after application, preventing the glue from hardening and making adjustments difficult, thus improving glue application consistency.

[0033] A suction pipe is fixedly connected between the input end of the delivery pump 32 and the glue storage tank 31, and a delivery pipe is fixedly connected between the output end of the delivery pump 32 and the glue application pipe 34. The delivery pipe is a rubber hose, and its length is adapted to the displacement distance of the mounting frame 33.

[0034] The working principle of the above embodiments is as follows:

[0035] In operation, the drive motor 13 starts, driving the conveyor belt 12 inside the base 11 to transport the silicon steel sheet to be coated to below the gantry frame 2. Simultaneously, the electric push rods 41 of the two sets of limiting mechanisms 4 move synchronously, pushing the connecting frame 42 closer to the silicon steel sheet, causing multiple equally spaced limiting wheels 43 to contact the edges of the silicon steel sheet. This centers and limits the silicon steel sheet during transport, preventing it from shifting due to equipment vibration. Then, the telescopic cylinder 35 of the coating device 3 drives the mounting frame 33 downwards, bringing the coating pipe 34 closer to the surface of the silicon steel sheet. At this time, the conveying pump 32 draws adhesive from the storage tank 31 through the suction pipe and transports it to the coating pipe 34, from which adhesive is applied to the surface of the silicon steel sheet. As the frame 33 moves downward, the transmission plate 56, which is fixedly connected to it, synchronously drives the piston rod 55 to move downward, pushing the piston plate 54 to move downward inside the piston cylinder 53. The gas is transported to the spray pipe 52 through the conveying pipe 58, and then blown onto the area where the adhesive has just been applied through the inclined nozzle, using the airflow pressure to spread the adhesive layer. When the adhesive application is completed, the telescopic cylinder 35 drives the mounting frame 33 to rise, and the transmission plate 56 and piston rod 55 move upward accordingly. The piston plate 54 moves upward under the restoring force of the buffer spring 57 and its own gravity. External gas enters the piston cylinder 53 through the air inlet pipe 59 to complete the intake, preparing for the next adhesive application and blowing. At the same time, the conveyor belt 12 transports the coated silicon steel sheet to the next process, completing one adhesive application cycle.

Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply.
