Technical Field

[0001] This utility model belongs to the field of adhesive sheet production technology, specifically relating to a metering rod pushing device for PTFE adhesive sheet production. Background Technology

[0002] PTFE bonding sheet is a sheet-like high-frequency copper-clad laminate substrate made from polytetrafluoroethylene (PTFE) resin using a special process. This product possesses excellent dielectric properties (low dielectric constant and low dielectric loss), superior resistance to high and low temperatures, outstanding chemical stability, and anti-aging capabilities. Its surface undergoes special treatment, allowing it to form a strong bond with copper foil through a high-temperature pressing process, providing a stable, low-loss circuit platform for high-frequency, high-speed signal transmission. It is widely used in electronic equipment fields with extremely high signal integrity requirements, such as 5G communications, satellite systems, millimeter-wave radar, high-end RF components, and aerospace.

[0003] During the PTFE coating and material pulling process, the weight of the bonding sheet may fluctuate at one or more points, and the overall weight cannot be controlled at the median value. To address this issue, physical intervention is needed to address the fluctuating bonding sheet positions to ensure that their weights are consistent with those at other locations.

[0004] To address the aforementioned issues, this application proposes a metering rod pushing device for PTFE bonding sheet production. Utility Model Content

[0014] 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. Example

[0015] Please see Figures 1-4 The present invention provides the following technical solution: a PTFE adhesive sheet production metering rod pushing device, wherein the pushing mechanism 4 is installed on the frame 1, a horizontal plate 11 is installed on the frame 1, a main pushing mechanism 2 is installed on the horizontal plate 11, a linear track 3 is installed on the main pushing mechanism 2, and the pushing mechanism 4 is installed on the linear track 3. The main push mechanism 2 and the linear track 3 are arranged in two opposing sets. The linear track 3 and the pushing mechanism 4 on the two main push mechanisms 2 are staggered. At the same time, multiple sets of horizontally arranged pushing mechanisms 4 are installed on both linear tracks 3. When the PTFE sheet passes through longitudinally, tension is generated. The pushing mechanism 4 is set along the width direction of the PTFE sheet. The pushing mechanism 4 pushes the PTFE sheet at multiple points in the width direction of the PTFE sheet, thereby realizing the measurement of the sheet thickness. The greater the pressure, the thinner the PTFE sheet, and the smaller the pressure, the thicker the PTFE sheet. Multiple sets of pushing mechanisms 4 on the same side are connected to a metering rod 47 at their front ends. Each set of pushing mechanisms 4 can independently adjust the pressure applied to the PTFE sheet by the pushing mechanism 4. The metering rod 47 is in tangential contact with the PTFE sheet. The pushing mechanism 4 and the PTFE sheet are made into line contact through the metering rod 47, thereby enabling range adjustment.

[0016] Furthermore, the single-unit pushing mechanism 4 includes an adjusting seat 41 that is slidably connected to the linear track 3. After the adjusting seat 41 slides with the linear track 3, it can be tightened by bolts to ensure the position of the pushing mechanism 4 on the linear track 3. The adjusting seat 41 is provided with a rotating adjusting screw 42. An adjusting block 43 that is threadedly connected to the adjusting seat 41 and engages with the adjusting screw 42 is slidably connected to the adjusting seat 41. A pushing rod 44 is fixed on the adjusting block 43. A retaining seat 45 is fixed to the front end of the pushing rod 44. A retaining block 46 is connected to the front end of the retaining seat 45.

[0017] The locking block 46 is a crescent shape made of Teflon material and is radially engaged with the measuring rod 47, while also being able to slide axially relative to it. The soft Teflon material facilitates the insertion and axial adjustment of the measuring rod 47; moreover, the crescent shape is larger than a semicircle, which can stably hold the measuring rod 47 in place and prevent it from falling off; the Teflon material can also reduce the friction between it and the PTFE sheet.

[0018] Furthermore, one end of the adjusting screw 42 passes through the adjusting seat 41 and is fixed with a handwheel 48. The handwheel 48 is used for manual adjustment of the pushing mechanism 4, thereby changing the pressure between the measuring rod 47 and the PTFE sheet.

[0019] Furthermore, the main push mechanism 2 includes a bracket 21 fixed to the horizontal plate 11. The bracket 21 is equipped with a rotating main push screw 22. A threaded sleeve 23 is externally connected to the main push screw 22. A vertical frame 24 is fixed on the threaded sleeve 23. The push mechanism 4 and the vertical frame 24 are fixedly installed. A guide rod with the same horizontal level as the main push screw 22 is installed on the bracket 21. The threaded sleeve 23 is slidably connected to the guide rod. The guide rod provides support and stability for the vertical frame 24, the linear track 3, and the push mechanism 4 within the range of the linear track 3.

[0020] The output end of the main push screw 22 is mounted on the side of the motor 25, which is coaxially fixed with the main push screw 22. The motor 25 can be used in conjunction with the sensor. When the equipment is running, the motor 25 pushes all the push mechanisms 4 on the same side to approach the PTFE sheet and forms tension on the PTFE sheet with the cooperation of multiple sets of push mechanisms 4 on both sides. The tension and the contact pressure between all push mechanisms 4 and the PTFE sheet can be adjusted by the motor 25.

[0021] The working principle and usage process of this utility model are as follows: The main push mechanism 2 is used to adjust the pressure between all the push mechanisms 4 on the same side and the PTFE sheet. Each push mechanism 4 is used to adjust the local pressure between the metering rod 47 and the PTFE sheet.

[0022] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
