[0043] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] Reference Figure 1-7 ,

[0045] A PTFE tape cutting and folding device includes: a mounting bracket 1, a cutting component 2, a conveying component 3, a first guide roller 4, a second guide roller 5, and a third guide roller 6. The bracket is used to mount the cutting component 2, the conveying component 3, the first guide roller 4, the second guide roller 5, and the third guide roller 6.

[0046] The conveyor 3 is used to guide the PTFE tape sequentially through the cutter 2, the first guide roller 4, the second guide roller 5, and the third guide roller 6. The conveyor 3 includes a first drive motor, a first drive roller 31, a second drive roller 32, and a tape roller mounting bracket 1. The PTFE tape roller is rotatably mounted on the tape roller mounting bracket 1. The first drive roller 31 and the second drive roller 32 clamp the PTFE tape. The first drive motor is used to drive the first drive roller 31 to rotate, thereby pulling the PTFE tape off the PTFE tape roller.

[0047] The cutting component 2 forms multiple cutting sections for cutting PTFE tape. The cutting component 2 includes: a fixed roller 21 and multiple cutters 22; the cutting edges of the cutters 22 form the cutting sections; multiple grooves 211 are formed on the fixed roller 21, and the cutters 22 are inserted into the grooves 211. The grooves 211 are annular grooves; the number of grooves 211 is greater than the number of cutters 22. The cutters 22 cut the PTFE tape. The greater number of grooves 211 allows for self-adjustment of the cutter 22's position, thereby automatically adjusting the width of the PTFE tape after cutting. The annular grooves 211 facilitate the installation and adjustment of the cutter 22's position.

[0048] The first guide roller 4, the second guide roller 5, and the third guide roller 6 form a guide trajectory for the PTFE tape to bend multiple times. The first guide roller 4 and the second guide roller 5 are located at the same height; the third guide roller 6 is located below the first guide roller 4 and the second guide roller 5 and in the middle of the first guide roller and the second guide roller; the minimum distance between the first guide roller 4 and the second guide roller 5 is less than the diameter of the third guide roller 6; preferably, the minimum distance between the first guide roller 4 and the second guide roller 5 is less than the radius of the third guide roller 6. This causes the PTFE tape, after being cut, to undergo multiple bends between the first guide roller 4, the second guide roller 5, and the third guide roller 6, with bending angles approaching 90°, thus achieving the effect of folding the PTFE tape.

[0049] Specifically, the conveyor 3 also includes a rotating power component, which drives the first guide roller 4, the second guide roller 5 and the third guide roller 6 to rotate, thereby playing the role of conveying the PTFE belt.

[0050] Specifically, the cutting component 2 further includes: a rotating roller 23, a connecting frame 24, and a connecting shaft 25; the rotating roller 23 is rotatably connected to the mounting bracket, the connecting frame 24 is fixed to the rotating roller 23, the connecting shaft 25 is fixed to the connecting frame 24, and the fixed roller 21 is fixed to the connecting shaft 25; an insertion hole is formed on the bracket, and the rotating roller 23 is inserted into the insertion hole, with the rotating roller 23 tightly fitted to the insertion hole. Since the rotating roller 23 is tightly fitted to the insertion hole, rotating the rotating roller 23 to any position will make the rotating roller 23 relatively stationary with respect to the insertion hole, thus fixing the rotating roller 23. The rotation of the rotating roller 23 allows the cutter 22 to cut the PTFE tape at different angles. The mounting frame 1 is also equipped with a support roller 26, which is located below the cutter 22. The support roller 26 is used to support the PTFE tape passing through the cutter 22. The rotating roller 23 makes the cutting part of the cutter 22 tangent to the support roller 26, thereby better cutting the PTFE tape and ensuring the cutting effect.

[0051] Specifically, the mounting frame 1 is provided with multiple partition rods 7; the partition rods 7 are spaced apart, forming a passage gap between them for the PTFE tape to pass through. The mounting frame 1 is also provided with multiple fixing plates 71 and guide members 72; the guide member 72 is a plate body, the fixing plates 71 are fixed to the mounting frame 1, and the guide member 72 is connected to the fixing plates 71; a conical cavity 73 is formed in the guide member 72; the conical channel is formed by bending the plate body. The partition rods 7 facilitate the separation of the cut PTFE tape, which then passes sequentially through the conical cavity 73, which allows the PTFE tape passing through the passage gap to pass through. The conical cavity 73 facilitates the tightening of the PTFE tape, thus changing the PTFE tape from a wide and loose state to a narrow and tight state.

[0052] Specifically, the mounting bracket 1 is also equipped with a heating element 74, which is used to heat the PTFE tape passing through the tapered cavity 73. The heating element 74 is a box that can form a heating chamber. Heating is achieved by setting multiple heating tubes in the heating chamber. Multiple passage holes are opened on the box to allow the PTFE tape passing through the tapered cavity 73 to pass through, thereby realizing the heating of the PTFE tape after cutting and trimming.

[0053] Specifically, the mounting frame 1 is also equipped with a first pressure roller 75, a second pressure roller 76, and a displacement power component 77. The first pressure roller 75 is rotatably connected to the mounting frame 1. The displacement power component 77 is mounted on the mounting frame 1 and is used to drive the second pressure roller 76 to move downward and upward. The downward movement of the second pressure roller 76 presses the PTFE tape passing through the heating element 74, thereby making the PTFE tape more compact. The displacement power component 77 is one of a cylinder, a lead screw and nut pair, or a hydraulic cylinder.

[0054] Specifically, the cutting and folding device also includes a winding machine 8, which employs existing technology. The winding machine 8 is used to wind the PTFE tape that has passed through the first guide roller 4, the second guide roller 5, and the third guide roller 6.

[0055] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
