Description

Technical Field

[0001] The utility model relates to the technical field of PTFE base cloth paving, and more specifically, it relates to a PTFE base cloth paving mechanism. Background Technique

[0002] In the existing technology, the PTFE (polytetrafluoroethylene) base cloth paving mechanism is a key device for evenly spreading the PTFE base cloth, and it plays a crucial role in the manufacture of PTFE composite materials and filter materials. However, there are some problems in the use of the existing PTFE base cloth paving mechanism, especially in adjusting the pressure of the pressure roller on the base cloth. These problems are mainly manifested in the following aspects:

[0003] Firstly, when adjusting the pressure of the pressure roller on the base cloth in the existing PTFE base cloth paving mechanism, complex operation steps are often required. Since the shapes and sizes of the pressure rollers may vary, the existing adjustment methods may not be applicable to all types of pressure rollers. This results in that in actual operation, the staff need to spend more time and energy to ensure that the pressure of the pressure roller on the base cloth reaches the ideal state. In addition, due to the cumbersome adjustment process, misoperations are likely to occur, thus affecting the paving effect.

[0004] Secondly, when adjusting the pressure of the pressure roller in the existing PTFE base cloth paving mechanism, special tools or equipment may be required. These tools or equipment may not be easy to carry or operate, further reducing the convenience of the paving mechanism. In some cases, the staff may need to wait for the arrival of professional equipment to complete the adjustment of the pressure roller pressure, which undoubtedly prolongs the working time of the paving mechanism and affects the efficiency of the entire production process.

[0018] Beneficial effects:

[0019] 1. The design of the adjusting mechanism enables the PTFE base fabric paving mechanism to adjust the pressure of the pressure roller on the base fabric as needed. Through the combination of the driving mechanism, vertical plate, fixed rod, side plate, cylinder, intermediate rod, follower spring, pressure roller, insertion sleeve, insertion rod, and fixing mechanism, the operator can easily adjust the position and pressure of the pressure roller, enabling the pressure roller to be precisely adjusted according to the thickness and material of the base fabric. The configuration of the follower spring provides elastic support, keeping the pressure roller stable during the adjustment process. The setting of the insertion rod and insertion sleeve allows the operator to adjust the compression range of the pressure roller as needed, thereby achieving different pressures on the base fabric.

[0020] 2. The design of the fixing mechanism ensures the stability and reliability of the PTFE base fabric paving mechanism during operation. Through the combination of the limit block and the baffle, the fixing mechanism can fix the position of the pressure roller within a certain range, avoiding the displacement or skew of the pressure roller during operation.
