Description

Technical Field

[0001] This utility model belongs to the field of fiberglass processing equipment, specifically relating to a bidirectional foldable and convenient yarn picking device for chopped yarn. Background Technology

[0002] The fiber picker is a common and essential device in fiberglass processing. Its main function is to extract the bundled fiberglass from the spool and guide it to the left or right of the subsequent fiberglass processing equipment to be processed into fiberglass products for different purposes. To avoid tangling, the picker point is generally located at the center of the fiber roll. After picking, the picker rod needs to be folded to remove the fiber roll.

[0003] The existing device has a complex structure and high cost. It is easily damaged when used frequently. Although the yarn picking rod can rotate and fold in both directions, it does not have a one-way locking function. As a result, the position of the yarn picking rod is easily moved when the subsequent processing equipment guides the yarn in one direction, which can lead to yarn breakage and difficulty in guiding the yarn. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model proposes a bidirectional foldable and convenient yarn picking device for chopped yarn.

[0005] The specific solution of this utility model is as follows:

[0006] A convenient, bidirectional foldable yarn picking device for chopped yarn is characterized by comprising a fixed mounting bracket, which includes an upper section and a lower section. The bottom of the upper section and the top of the lower section have two pairs of corresponding fixed bolt arc grooves. Each pair of fixed bolt arc grooves includes two arc-shaped slots with opposite protrusion directions. The bolts can slide within the slots and be fixed by nuts. The bottom of the fixed bolt arc groove is higher than the top of the yarn roll in the installed state. The bottom of the lower section has a yarn guide ceramic eye tube.

[0007] Preferably, the yarn guide ceramic eye tube is an in-depth yarn guide ceramic eye tube.

[0008] Preferably, the arc of the slot is 90 degrees.

[0009] Preferably, the yarn guide ceramic eye tube has double ceramic eyes and the opening faces downwards.

[0010] Preferably, the upper section has a yarn frame connecting piece at its top end.

[0011] Preferably, the width of the fixed mounting bracket is 25-35mm, the thickness is 4-6mm, the center axis of the arc groove of the fixing bolt is Φ25mm, and the included angle of the center is 45°.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model has an arc-shaped sliding groove device that can be easily rotated and folded to the left or right (depending on the direction of yarn feeding) by sliding the bolts in the arc-shaped groove. It is fixed with two bolts and has a one-way locking function, which can prevent the yarn picking rod from moving due to yarn tension during subsequent fiberglass processing equipment, thus preventing yarn breakage and yarn feeding difficulties.

[0014] The device, through the design of the arc groove structure and the appropriate fixing of the two ends with bolts, meets the process requirements that the yarn take-up bracket can be locked and fixed during yarn feeding, and can be easily rotated 90° to the left or right and folded after yarn feeding to facilitate the removal of the yarn roll. It does not have the defect of easy position change during yarn feeding.

[0015] In addition, this yarn feeding device is ingeniously designed, reliable in operation and not easily damaged, and extremely simple and inexpensive to process; moreover, the preferred yarn guide ceramic eye tube adopts a double ceramic eye design with the opening facing downward, which not only makes yarn feeding convenient and quick, but also has good yarn guiding performance and does not easily cause yarn to tangle or pile up.

[0016] This device is suitable for the yarn feeding stage of equipment such as chopped strand machines and warp knitting machines used in the fiberglass industry. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Example

[0024] A convenient, bidirectional, foldable, short-cut yarn picking device, such as... Figure 1-3 As shown, the device includes a fixed mounting bracket, which includes an upper section 1 and a lower section 4. The bottom of the upper section 1 and the top of the lower section 4 have two pairs of corresponding fixing bolt arc grooves 2. Each pair of fixing bolt arc grooves 2 includes two arc-shaped slots with opposite protrusion directions. Bolts 7 can slide in the slots and be fixed by nuts.

[0025] The bottom of the arc groove 2 of the fixing bolt is higher than the top of the yarn roll 3 in the installed state to ensure that the yarn roll 3 can be taken out.

[0026] The upper section 1 has a yarn frame connecting piece 6 at its top end, which can be fixed to the yarn frame by bolts, and the upper section 1 is perpendicular to the yarn frame crossbeam.

[0027] The bottom of the lower section 4 has a deep-penetrating yarn guide ceramic eye tube 5, which has double ceramic eyes and an opening facing downwards.
