Description

Technical Field

[0001] The present application relates to the technical field of coating machines, and in particular to an anti-deviation device for a coating machine. Background Art

[0002] The scientific name of Teflon cloth is polytetrafluoroethylene coated glass fiber cloth, also known as Teflon high temperature resistant paint cloth. It is made of suspended polytetrafluoroethylene emulsion as raw material and impregnated with high performance glass fiber cloth.

[0003] An existing patent (publication number: CN220573930U) discloses a coating structure with an anti-drift assist function. The structure comprises a coating roller and a U-shaped plate disposed externally thereto. A roller shaft is fixedly mounted in the middle of the coating roller, with brackets rotatably connected to each end of the shaft. Both ends of the roller shaft are rotatably connected to the inner sidewall of the U-shaped plate via rolling bearings. Both ends of the roller shaft extend through the exterior of the U-shaped plate. Anti-drift plates are installed on either side of the coating roller. The plates have through-holes in the middle, with the ends of the coating roller passing through each through-hole. An adjustment mechanism is located within the U-shaped plate, located below the coating roller, to facilitate adjusting the spacing between the anti-drift plates. This structure prevents Teflon fabric from drifting during the coating process, thereby reducing wrinkles and uneven coating.

[0004] The above-mentioned device rotates the wheel according to the width and scale of the Teflon cloth, and the wheel drives the bidirectional screw to rotate, and the bidirectional screw adjusts the distance between the two anti-deviation plates. After the adjustment is completed, the two anti-deviation plates can limit the Teflon cloth to prevent the Teflon cloth from deviating during the coating process, thereby reducing the probability of wrinkles and uneven coating of the Teflon cloth. However, during the adjustment process, the user needs to observe the scale line while rotating the wheel, which is inconvenient to adjust and requires multiple adjustments, resulting in poor adjustment accuracy. Secondly, after the adjustment is completed, with the vibration of the motor and the rotation of the coating roller, the anti-deviation plate is likely to move on its own. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides an anti-deviation device for a coating machine, which has the advantages of fast and precise adjustment and pre-cleaning, and solves the problems raised in the background technology.

The distance sensor can accurately measure the distance between the two limit rings and automatically adjust the position of the limit ring according to the actual width of the material. There is no need for multiple manual adjustments, which greatly improves the adjustment accuracy and efficiency. The combination of the worm and the worm gear is used to achieve the self-locking function of the bidirectional threaded rod, avoiding the problem of self-movement of the limit ring due to motor vibration or rotation of the coating roller during the coating process, ensuring the stability and consistency of the coating process. The setting of the de-dusting pipe and its spray hole facilitates the cleaning of the material surface before coating. The airflow provided by the pump body can remove impurities and dust on the material surface, improve the coating effect, and reduce uneven coating or quality problems caused by impurities.

[0009] Furthermore, a bidirectional threaded rod is rotatably connected between the bottom ends of the two shaft seats, and the bottom end of each limiting ring is threadedly connected to both ends of the bidirectional threaded rod respectively.

[0010] Through the above solution and the provision of the bidirectional threaded rod, the purpose of moving the two limiting rings away from or closer to each other can be achieved.

[0011] Furthermore, the front end of the bidirectional threaded rod is fixedly connected to a worm gear, the front face of the frontmost shaft seat is fixedly connected to two self-locking plates, a worm is rotatably connected between the two self-locking plates, and the worm is meshingly connected to the worm gear.

[0012] Through the above solution, by arranging the worm and the worm wheel, the self-locking purpose of the bidirectional threaded rod can be achieved, and the self-movement of the limit ring can be effectively avoided.

[0013] Furthermore, a pump body is installed at the rear end of the upper surface of the bottom plate, the output end of the pump body is fixedly connected to a hose, and the other end of the hose is fixedly connected to the debris removal pipe.

[0014] Through the above solution and the arrangement of the pump body, an air source can be provided for the impurity removal pipe.

[0015] Furthermore, a motor is installed at the front end of the upper surface of the base plate, and the output end of the motor is fixedly connected to one end of the worm.

[0016] Through the above solution, by setting the motor, power can be provided for the rotation of the worm.

[0017] Furthermore, a motor is installed on the front side of the frontmost shaft seat, and the output end of the motor is connected to the coating roller.

[0018] Through the above solution, by setting the motor, it is possible to provide power for the rotation of the coating roller.

[0019] Furthermore, a control host is installed on the upper surface of the pump body, and the pump body, motor and distance sensor are all electrically connected to the control host.

[0020] Through the above solution, by controlling the settings of the host, the purpose of monitoring the spacing of the limit rings can be achieved.

[0021] Furthermore, the surfaces of the two limiting rings that are close to each other are both set as smooth surfaces.

[0022] According to the above solution, the surfaces of the two limiting rings that are close to each other are set as smooth surfaces, which can effectively reduce the wear on the material.

[0023] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0024] The anti-deviation device for a coating machine realizes automatic adjustment of the material width during the coating process by combining a distance sensor and a bidirectional threaded rod.

The two distance sensors 5 are optically connected, and a bidirectional threaded rod 9 is rotatably connected between the bottom ends of the two shaft seats 2. The bottom end of each limit ring 4 is threadedly connected to the two ends of the bidirectional threaded rod 9 respectively. Through the setting of the bidirectional threaded rod 9, the two limit rings 4 can be moved away from or close to each other.

[0033] See also Figure 1 、 Figure 2 and Figure 4 The front end of the bidirectional threaded rod 9 is fixedly connected to a worm gear 10, and the front of the frontmost shaft seat 2 is fixedly connected to two self-locking plates 11. A worm 12 is rotatably connected between the two self-locking plates 11, and the worm 12 is meshed with the worm gear 10. Through the arrangement of the worm 12 and the worm gear 10, the self-locking purpose of the bidirectional threaded rod 9 can be achieved, and the self-movement of the limit ring 4 can be effectively avoided. One side of the two shaft seats 2 is fixedly connected to a support frame 6, and a de-impurity pipe 7 is fixedly connected between the tops of the two support frames 6. A group of spray holes 8 are opened on the outer surface of the de-impurity pipe 7. Through the arrangement of the spray holes 8, air flow can be output to clean the surface of the material to be applied.

[0034] See also Figure 1 、 Figure 2 and Figure 3A pump body 13 is installed at the rear end of the upper surface of the base plate 1. The output end of the pump body 13 is fixedly connected to a hose 14. The other end of the hose 14 is fixedly connected to the debris removal pipe 7. Through the setting of the pump body 13, an air source can be provided for the debris removal pipe 7. A motor 15 is installed at the front end of the upper surface of the base plate 1.

[0035] See also Figure 1 、 Figure 2 and Figure 3 A control host 17 is installed on the upper surface of the pump body 13. The pump body 13, the motor 15 and the distance sensor 5 are all electrically connected to the control host 17. Through the setting of the control host 17, the purpose of monitoring the spacing of the limit rings 4 can be achieved. The sides of the two limit rings 4 that are close to each other are set as smooth surfaces. By setting the sides of the two limit rings 4 that are close to each other as smooth surfaces, the wear on the material can be effectively reduced.

[0036] In this embodiment, an anti-deviation device for a coating machine realizes automatic adjustment of the material width during the coating process through the combined use of a distance sensor 5 and a bidirectional threaded rod 9. The distance sensor 5 can accurately measure the distance between the two limit rings 4 and automatically adjust the position of the limit ring 4 according to the actual width of the material. There is no need for multiple manual adjustments, which greatly improves the adjustment accuracy and efficiency. The combination of the worm 12 and the worm gear 10 realizes the self-locking function of the bidirectional threaded rod 9, avoiding the self-movement problem of the limit ring 4 caused by the vibration of the motor 16 or the rotation of the coating roller 3 during the coating process, ensuring the stability and consistency of the coating process. The setting of the de-dusting pipe 7 and its spray hole 8 provides convenience for cleaning the material surface before coating. The airflow provided by the pump body 13 can remove impurities and dust on the material surface, improve the coating effect, and reduce uneven coating or quality problems caused by impurities.

[0037] The working principle of the above embodiment is as follows: first, the material is placed in the working area of the coating machine and is ready for coating operation. At this time, the pump body 13 is started and a stable airflow is provided to the de-dusting pipe 7 through the hose 14. The nozzle 8 on the de-dusting pipe 7 sprays the airflow evenly to the surface of the material to remove impurities and dust thereon and prepare for the subsequent coating process. Next, the control host 17 starts the system and the distance measuring sensor 5 starts working. They are connected through an optical path to accurately measure the distance between the two limit rings 4 and transmit the data to the control host 17 in real time. The control host 17 determines whether the position of the limit ring 4 needs to be adjusted according to the preset material width or the real-time detected width. If adjustment is required, the control host 17 will instruct the motor 15 to start and the motor The worm 12 is driven by the motor 15 to rotate, and the worm 12 is engaged with the worm wheel 10 to drive the bidirectional threaded rod 9 to rotate. Since the limit ring 4 is threadedly connected to the two ends of the bidirectional threaded rod 9, the rotation of the bidirectional threaded rod 9 will cause the two limit rings 4 to move away from or approach each other until the preset or detected material width is reached. After the adjustment is completed, the motor 16 is started to drive the coating roller 3 to rotate. The material moves forward driven by the coating roller 3 and is evenly coated with paint. Due to the presence of the limit ring 4, the material can maintain a stable width during the coating process to prevent deviation. At the same time, the self-locking function of the worm 12 and the worm wheel 10 ensures that the limit ring 4 will not move due to the vibration of the motor 16 or the rotation of the coating roller 3 during the coating process, thereby ensuring the stability and consistency of the coating.
