Technical Field

[0001] This utility model relates to the field of composite material application technology, and in particular to a straight yarn separating comb with adjustable comb tooth spacing. Background Technology

[0002] Prepreg production typically uses a single specification of fiber material. However, sometimes, due to various factors, it is necessary to mix different specifications of fiber materials. In most cases, different specifications of fibers have different linear densities, and existing adjustable yarn separating combs usually have an equidistant tooth spacing structure, which cannot meet the requirement of uniform fiber surface density distribution. In addition, in some scenarios, it is necessary to make localized and precise adjustments to the fiber distribution, which traditional equidistant yarn separating combs cannot achieve.

[0003] Therefore, there is an urgent need for a straight-line yarn separating comb with adjustable tooth spacing. Utility Model Content

Detailed Implementation

[0018] 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.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figures 1 to 7 This utility model provides a straight yarn separating comb with adjustable tooth spacing, including a frame, multiple adjustment mechanisms 2 and multiple comb teeth 3; The frame includes a pair of horizontally arranged frame bodies 4, with guide grooves 6 on both side walls of the frame bodies 4 and an elongated through hole 12 in the center of the frame bodies 4. The adjustment mechanism 2 includes an adjustment frame 16 that is slidably fitted on a pair of frames 4. The adjustment frame 16 includes a top plate and a pair of side plates. A sliding boss 21 is provided on the side plate. The sliding boss 21 is slidably fitted with the guide groove 6. A threaded through hole 22 is provided on the sliding boss 21. A locking stud 17 is threadedly fitted in the threaded through hole 22. The locking stud 17 is used to abut against the bottom surface of the guide groove 6. A tensioning stud 19 is provided on the top plate. The tensioning stud 19 is slidably fitted in the elongated through hole 12. Multiple comb teeth 3 are arranged between multiple pairs of tension studs 19.

[0021] By rotating the locking stud 17 to engage with the threaded through hole 22, the position of the locking stud 17 can be adjusted, thereby enabling the locking device of the adjustment frame 16 on the frame 4. Furthermore, the position of multiple comb teeth 3 can be adjusted by sliding the position of the adjustment frame 16, thereby adjusting the spacing between the two comb teeth 3.

[0022] In one embodiment of this utility model, a pair of frame bodies 4 with opposite end faces are respectively connected to guide bars 8 by supports 7. A first through hole 23 is provided on the top plate. A tensioning stud 19 is slidably fitted in the first through hole 23. A limit groove 27 is provided on the tensioning stud 19. The guide bar 8 is slidably fitted with the limit groove 27. An adjusting nut 18 is threaded on the tensioning stud 19. The adjusting nut 18 is located between the frame body 4 and the guide bar 8.

[0023] By rotating the adjusting nut 18, the tensioning stud 19 will not rotate due to the limiting groove 27 and the guide bar 8. Thus, the height position of the tensioning stud 19 can be adjusted by the threaded engagement between the adjusting nut 18 and the tensioning stud 19, thereby adjusting the tension of a single comb tooth 3.

[0024] In one embodiment of this utility model, a spring washer 20 is provided between the adjusting nut 18 and the top plate, and the spring washer 20 can prevent the comb teeth 3 from loosening during use.

[0025] In one embodiment of this utility model, a limiting boss 26 is provided at the bottom end of the limiting groove 27, and a second through hole 25 is provided on the limiting boss 26. The end of the comb tooth 3 is installed in the second through hole 25.

[0026] In one embodiment of this utility model, the comb teeth 3 include a tension line 28 and limiting particles 29 disposed at both ends of the tension line 28. The tension line 28 is used to pass through the second through hole 25, and the limiting particles 29 are larger than the second through hole 25.

[0027] The tensioning wire 28 passes through the second through hole 25 of the tensioning stud 19. The outer dimension of the limiting particle 29 is between the size of the second through hole 25 of the tensioning stud 19 and the outer edge size of the limiting boss 26. When tensioned, it is stuck on the limiting boss 26.

[0028] In one embodiment of this utility model, a pair of frame bodies 4 are threaded together with a plurality of connecting pillars 5.

[0029] In one embodiment of this utility model, the connecting support 5 includes an intermediate section 15 and a threaded section 14. The frame 4 has a guide hole 9 and a threaded groove 10 that are connected in sequence. The diameter of the threaded groove 10 is smaller than that of the guide hole 9. The intermediate section 15 is engaged with the guide hole 9, and the threaded section 14 is threadedly engaged with the threaded groove 10.

[0030] The rotating connecting support 5 can adjust the spacing between a pair of frame bodies 4 through threaded engagement. The outer diameter of the threaded section 14 is smaller than the size of the middle section 15. The middle section 15 engages with the guide hole 9 to increase the stability of the frame.

[0031] In one embodiment of this utility model, a scale 11 is provided on the side wall of the frame 4 to indicate the position of the adjustment mechanism 2.

[0032] In one embodiment of this utility model, an indicator arrow 24 corresponding to the scale 11 is provided on the side plate to locate the position of the comb teeth 3 in conjunction with the scale 11.

[0033] In one embodiment of this utility model, a plurality of fixed brackets 13 are provided on the end face of any frame 4 away from the other frame 4, for fixing the yarn separating comb in the working position.

[0034] How to use: When the tension line 28 of the comb tooth 3 is passed through the second through hole 25 of the tensioning stud 19 from top to bottom, the limiting particle 29 at the end will be stuck on the limiting boss 26 of the tensioning stud 19.

[0035] Pass the tensioning stud 19 with the comb teeth installed through the first through hole 23 on the upper part of the adjusting frame 16, and then put on the spring washer 20 and the adjusting nut 18 in sequence, and tighten them initially.

[0036] The adjusting mechanism 2 is embedded into the guide groove 6 of the frame 4 via its sliding boss 21. Ensure that the limiting groove 27 of the tensioning stud 19 is engaged with the guide bar 8 to prevent it from rotating.

[0037] The entire yarn separating comb is securely installed onto the designated station of the prepreg production equipment using the fixing bracket 13. Manually slide the adjustment mechanism 2 along the guide groove 6 of the frame 4; By observing the corresponding scale of the indicator arrow 24 on the adjustment frame 16 and the scale 11 on the frame 4, the comb teeth 3 can be precisely moved to the desired approximate position.

[0038] After the adjustment mechanism 2 is slid to the target position, tighten the locking stud 17 with a tool. The locking stud 17 will press against the guide groove 6, thereby firmly fixing the entire adjustment frame 16 to the frame 4 and preventing it from moving accidentally in subsequent operations.

[0039] After locking the comb teeth position, use a tool to rotate the adjusting nut 18 and pull the tensioning stud 19 upward to tension the tension line 28 of the comb teeth 3, making the comb teeth 3 taut.
