[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.
[0030] See also Figure 1-5 , the utility model provides the following technical solutions:
[0031] For example, see Figure 1 A polytetrafluoroethylene glass cloth cutting device comprises a conveying component 1 and a cutting component 2 and a slitting component 3 installed on the top of the conveying component 1. The cutting component 2 is located in front of the slitting component 3. The conveying component 1 is used to guide and convey the glass cloth. During the conveying process, the glass cloth first passes through the cutting component 2 and then passes through the slitting component 3. The cutting component 2 is used to cut the glass cloth, and the slitting component 3 is used to continuously slit the glass cloth so that the glass cloth forms glass cloths of different widths.
[0032] See also Figure 1-Figure 3 The conveying assembly 1 includes a base 11 and a bracket 13 installed on the top of the base 11. A servo motor 14 is installed on one side of the bracket 13. The output end of the servo motor 14 passes through the bracket 13 and is connected to a conveying roller 17. The servo motor 14 is used to drive the conveying roller 17 to rotate, and the glass cloth is delivered from the top of the conveying roller 17.
[0033] See also Figure 1-Figure 3 A workbench 12 is installed on the top of the base 11. The workbench 12 is located on the side of the cutting knife 24 away from the conveying roller 17. A plurality of rubber strips 18 are connected to the top of the workbench 12. During the conveying process of the glass cloth, the bottom surface of the glass cloth fits with the plurality of rubber strips 18 on the top of the workbench 12. The plurality of rubber strips 18 cooperate to increase the friction between the workbench 12 and the glass cloth. The conveying force of the conveying roller 17 and the friction force of the rubber strips 18 cooperate to pull each other, thereby preventing the glass cloth from overlapping and wrinkling during the conveying process.
[0034] See also Figure 1 , Figure 4 and Figure 5 The cutting assembly 2 includes a cutting knife 24 installed on the top of the base 11, the cutting knife 24 is in front of the conveying roller 17, a fixed knife 23 is arranged on the top of the cutting knife 24, and the fixed knife 23 and the cutting knife 24 are staggered. The glass cloth passes between the cutting knife 24 and the fixed knife 23 during the conveying process. The cutting assembly 2 also includes two first slide rails 21 symmetrically installed on the top of the base 11 and located on both sides of the fixed knife 23. The two sides of the fixed knife 23 are respectively inserted into the corresponding first slide rails 21. A cutting cylinder 22 is installed on the top of the two first slide rails 21. The piston rod of the cutting cylinder 22 extends to the corresponding first slide rail 21 and is connected to the fixed knife 23. The cutting cylinder 22 is used to push the two ends of the fixed knife 23 to slide inside the corresponding first slide rail 21, thereby controlling the fixed knife 23 to move down and overlap with the cutting knife 24, so as to achieve the purpose of cutting the glass cloth.
[0035] See also Figure 5 The bottom edge of the fixed knife 23 is provided with an inclined portion 25, and the top surface of the cutting knife 24 is arranged horizontally. The fixed knife 23 and the cutting knife 24 form an angle through the inclined portion 25. When the cutting knife 24 moves downward, the inclined portion 25 provided at the bottom edge of the fixed knife 23 is used to shear the glass cloth, thereby avoiding the deformation of the glass cloth caused by direct punching and cutting.
[0036] See also Figure 1Two fixing frames 16 are installed on the top of the base 11 and between the cutting knife 24 and the conveying roller 17. A guide roller 15 is connected between the two fixing frames 16. The length of the guide roller 15 is the same as the length of the supporting roller 32, and a plurality of annular grooves are equidistantly provided on the outer wall of the guide roller 15. In addition, the glass cloth passes under the guide roller 15 after passing through the fixed knife 23 and the cutting knife 24. This arrangement utilizes the guide roller 15 and the annular groove on the outer wall of the guide roller 15 to pull and tension the glass cloth, thereby further avoiding overlapping wrinkles on the glass cloth.
[0037] See also Figure 1-Figure 3 The slitting assembly 3 includes a supporting roller 32 arranged directly above the conveying roller 17, a gap is arranged between the supporting roller 32 and the conveying roller 17, and a plurality of annular cutters 33 are equidistantly installed on the outer wall of the supporting roller 32. The annular cutters 33 cooperate with the supporting roller 32 to maintain a stationary state. When the glass cloth is conveyed between the supporting roller 32 and the conveying roller 17, the supporting roller 32 and the annular cutters 33 cooperate to slit the glass cloth into glass cloths of different widths.
[0038] See also Figure 1 and Figure 2 Two second slide rails 31 are symmetrically installed on the top of the base 11 and on both sides of the support roller 32. Both ends of the support roller 32 extend to the inside of the corresponding second slide rail 31. A slitting cylinder 34 is installed on the top of one of the second slide rails 31. The piston rod of the slitting cylinder 34 extends to the inside of the corresponding second slide rail 31 and is connected to one end of the support roller 32. The height of the support roller 32 and the annular cutter 33 is adjustable, that is, the support roller 32 is pushed to slide inside the second slide rail 31 by the slitting cylinder 34, so as to adjust the distance between the support roller 32 and the conveying roller 17. When the distance increases, the annular cutter 33 is away from the glass cloth. When the distance decreases, the annular cutter 33 can realize the slitting of the glass cloth.
[0039] Specifically, the staff lays the glass cloth on the workbench 12, and one end of the glass cloth passes through the fixed knife 23 and the cutting knife 24 in sequence, and passes through the bottom of the guide roller 15 and the top of the conveying roller 17. The servo motor 14 drives the conveying roller 17 to rotate, thereby conveying the glass cloth. During the conveying process, if the glass cloth needs to be cut, the cutting knife 24 is pushed down by the cutting cylinder 22 to overlap with the fixed knife 23, thereby realizing the cutting of the entire section of the glass cloth. If the glass cloth needs to be cut, it is only necessary to separate the cutting knife 24 and the fixed knife 23, and push the supporting roller 32 down by the cutting cylinder 34, so that the annular cutting knife 33 is attached to the top surface of the glass cloth. As the glass cloth is continuously conveyed, the cutting effect of the glass cloth is achieved.
[0040] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
