Description

Technical Field

[0001] This utility model relates to the field of Teflon tape processing technology, specifically a surface coating device for Teflon tape processing. Background Technology

[0002] The reference patent title is: A Surface Coating Device for Teflon Tape Processing (Authorization Announcement No.: CN219092556U, Authorization Announcement Date: 2023.05.30). It includes a frame and a conveyor table. Tape is placed on the top surface of the conveyor table. A first support is fixedly connected to the top surface of the frame, and a second support is fixedly connected to the top surface of the frame. A motor is fixedly connected to the top surface of the second support. A fixing pipe is fixedly connected to the top surface of the first support. The lower end of the fixing pipe passes through the first support, and a connecting pipe is fixedly connected to the upper end of the fixing pipe. A spraying device is installed on the first support, and a coating device is installed below the second support. By adjusting the spraying device, the moving pipe can be adjusted to move the nozzle, thereby adjusting the distance between the nozzle and the tape. This ensures that the nozzle maintains a suitable height when spraying tape of different thicknesses, thus improving the coating quality.

[0003] Based on the aforementioned documents, Teflon tape, due to its high temperature resistance and strong corrosion resistance, is widely used in electronics, chemical and other fields. Its surface coating process directly determines the product performance. However, existing coating devices have some problems. Among them, the nozzle position of the coating component is mostly a fixed structure, which cannot flexibly adjust the spraying range according to the tape width. When adapting to different specifications of tape, although the distance between the nozzle and the tape can be adjusted by adjusting the height, thereby improving the spraying quality, when spraying tapes with large differences in width, simply adjusting the height will inevitably cause paint splattering and waste. Secondly, the lack of a stable positioning mechanism during tape conveying makes it easy for the coating area to be misaligned due to lateral displacement, affecting the tape coating quality. Therefore, this utility model provides a surface coating device for processing Teflon tape. Utility Model Content

[0014] Beneficial effects

[0015] This invention provides a surface coating device for processing Teflon tape. Compared with the prior art, it has the following advantages:

[0016] 1. This surface coating device for Teflon tape processing, through the setting of a coating mechanism, utilizes the synergistic effect of the lifting component and the coating component to achieve dual precise adjustment of the nozzle's "height + position". The lifting motor drives the lifting screw to move the nozzle within a height range of 5-30mm, which can adapt to Teflon tapes with a thickness of 0.1-5mm. When the sliding plate slides laterally along the sliding groove, combined with the intuitive readings of the scale plate and the distance measuring pointer, the nozzle can be quickly positioned to the target spraying position of the tape with a width of 50-500mm, without the need to change the coating module, and it is compatible with tapes of different specifications.

[0017] 2. This surface coating device for processing Teflon tape, by setting up a positioning component, uses the linkage structure of rotating gears and linkage toothed plates to drive the positioning plate to achieve lateral adjustment, which can control the lateral deviation of the tape within ±0.2mm, ensuring that the tape is always conveyed in the center. At the same time, the scraping component uses a distance sensor to detect the tape thickness in real time, and combined with the control of the adjusting cylinder, it can automatically and accurately adjust the height of the scraping plate to achieve the best scraping effect.

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A surface coating apparatus for processing Teflon tape includes a coating table 1, a tape roller 2 mounted on the left side of the coating table 1, a receiving roller 3 mounted on the right side of the coating table 1, a positioning component 4 inside the coating table 1, a baffle 5 mounted on the top of the coating table 1, a scraping component 6 mounted on the right side of the top of the baffle 5, and a coating mechanism 7 on the surface of the top of the baffle 5, the coating mechanism 7 including:

[0027] The coating assembly 71 includes a support plate 711 mounted on the surface of the baffle 5. A support rod 712 is slidably connected inside the support plate 711. An equipment plate 713 is fixedly connected to the top of the support rod 712. A sliding groove 714 is formed on the surface of the equipment plate 713. A sliding plate 715 is slidably connected to the inner surface of the sliding groove 714. A guide tube 716 is installed inside the sliding plate 715. A nozzle 717 is installed at the bottom end of the guide tube 716. A fixing bolt 718 is threaded inside the sliding plate 715. The inner side of the fixing bolt 718 is in contact with the surface of the equipment plate 713.

[0028] The ranging component 72 is disposed on the top of the device plate 713 and is used to measure the moving distance of the nozzle 717;

[0029] The lifting assembly 73 is located on one side of the baffle 5 and is used to adjust the height of the nozzle 717.

[0030] The receiving roller 3 is driven to rotate by a motor; the support plate 711 is used to limit the up and down sliding of the support rod 712; the inner side of the fixing bolt 718 is equipped with an anti-slip pad, which makes it easy to fully fit the surface of the equipment plate 713 and avoid slippage.

[0031] In this embodiment, the ranging component 72 includes a scale plate 721 mounted on the top of the device plate 713 and a ranging pointer 722 mounted on the top of the sliding plate 715.

[0032] The tip of the distance measuring pointer 722 is in contact with the scale on the surface of the scale plate 721.

[0033] In this embodiment, the lifting assembly 73 includes a lifting motor 731 installed on one side of the baffle 5. One end of the output shaft of the lifting motor 731 is fixedly connected to a lifting screw 732 via a coupling. The surface of the lifting screw 732 is threadedly connected to a lifting plate 733. The top of the lifting plate 733 is fixedly connected to the bottom end of the support rod 712.

[0034] The lifting motor 731 is a three-phase asynchronous motor, and the top of the lifting screw 732 is rotatably connected to the bottom of the support plate 711.

[0035] By incorporating a coating mechanism 7, the coordinated action of the lifting assembly 73 and the coating assembly 71 enables precise adjustment of the nozzle's "height + position." The lifting motor 731 drives the lifting screw 732 to move the nozzle 717 within a height range of 5-30mm, accommodating Teflon tapes with a thickness of 0.1-5mm. When the sliding plate 715 slides laterally along the sliding groove 714, combined with the intuitive readings from the scale plate 721 and the distance measuring pointer 722, the nozzle 717 can be quickly positioned at the target spraying position for tapes with a width of 50-500mm, without the need to replace the coating module, thus adapting to tapes of different specifications.

[0036] In this embodiment, the positioning component 4 includes a positioning motor 41 installed on the inner wall of the coating table 1. One end of the output shaft of the positioning motor 41 is fixedly connected to a rotating gear 42 via a coupling. The surface of the rotating gear 42 is connected to a positioning rod 44 inside the baffle 5 via a linkage component 43. One end of the positioning rod 44 is fixedly connected to a positioning plate 45.

[0037] The positioning motor 41 is mounted on the inner wall of the coating table 1 via a horizontal plate. The positioning motor 41 is a three-phase asynchronous motor.

[0038] In this embodiment, the linkage assembly 43 includes a linkage plate 431 that is slidably installed inside the coating table 1. One end of the linkage plate 431 is fixedly connected to the other end of the positioning rod 44. The other end of the linkage plate 431 extends through into the interior of the coating table 1 and is fixedly connected to a linkage toothed plate 432. One side of the linkage toothed plate 432 meshes with the surface of the rotating gear 42.

[0039] In this embodiment, the adhesive scraping assembly 6 includes a connecting plate 61 installed on the top right side of the baffle 5. An adjusting cylinder 62 is installed on the top of the connecting plate 61, and an adhesive scraper 63 is fixedly connected to the output end of the bottom of the adjusting cylinder 62. A distance sensor 64 is installed on one side of the connecting plate 61.

[0040] Distance sensor 64 is a laser displacement sensor.

[0041] A control panel is installed on the front side of the coating station 1. This control panel is used to control and regulate various electrical components in the device.

[0042] By incorporating a positioning component 4 and utilizing the linkage structure of a rotating gear 42 and a linkage toothed plate 432, the positioning plate 45 is driven to achieve lateral adjustment, which can control the lateral offset of the tape within ±0.2mm, ensuring that the tape is always conveyed in the center. At the same time, the scraper component 6 uses a distance sensor 64 to detect the tape thickness in real time, and combined with the control of the adjusting cylinder 62, it can automatically and accurately adjust the height of the scraper 63 to achieve the best scraping effect.

[0043] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0044] During operation, one end of the Teflon tape is first fixed to the surface of the receiving roller 3, and the bottom of the Teflon tape slides against the support plate on top of the coating table 1. Then, depending on the tape width, the positioning motor 41 is started via the control panel to drive the rotating gear 42 to rotate forward or backward. The rotating gear 42 meshes with the linkage gear plate 432, causing the linkage gear plate 432 to move laterally. The linkage gear plate 432 pushes the positioning rod 44 and the positioning plate 45 closer to the edge of the tape via the linkage plate 431. 45 pairs of Teflon tapes are centered and positioned to maintain stability during transport. Then, the operator loosens the fixing bolts 718 and pushes the sliding plate 715 laterally along the sliding groove 714. The sliding plate 715 drives the guide tube 716 and the nozzle 717 to move synchronously. The distance measuring pointer 722 moves with the sliding plate 715, and the scale value of the pointer on the scale plate 721 directly reflects the lateral position of the nozzle 717. After adjusting to the target position, the fixing bolts 718 are tightened. The friction between the 8 and the equipment plate 713 locks the sliding plate 715, achieving precise matching between the coating range and the tape width. The height of the nozzle 717 is then adjusted according to the thickness of the Teflon tape. The lifting motor 731 is activated via the control panel, driving the lifting screw 732 to rotate. Due to the threaded engagement between the lifting screw 732 and the lifting plate 733, the rotational motion of the lifting screw 732 is converted into the vertical linear motion of the lifting plate 733. The lifting plate 733 drives the support rod 712, equipment plate 713, and nozzle 717 to rise and fall synchronously until the distance between the nozzle 717 and the tape surface reaches a preset value. The distance sensor 64 then detects the tape thickness and transmits the detected data to the control panel. Based on the detected tape thickness information, the control panel flexibly adjusts the adjusting cylinder 62, enabling rapid adjustment of the initial height of the scraper 63. This facilitates subsequent scraping operations for different types of tape. Finally, the motor drives the receiving roller 3 to rotate, achieving the traction and conveying of the tape for coating operations.
