Description

Technical Field

[0001] This utility model relates to the field of weft knitting machine equipment technology, and in particular to a circular weft knitting machine needle hook adsorption device. Background Technology

[0002] In the prior art, Chinese invention patent application publication number 201811368556.0 discloses a circular weft knitting machine, including a frame, a yarn feeding mechanism mounted on the frame, and a knitting mechanism mounted on the frame. The knitting mechanism includes a cylinder rotatably mounted on the frame, multiple knitting needles vertically sliding on the cylinder, and a drive unit for rotating the cylinder. An auxiliary mechanism is provided on the frame, including an air nozzle connected to the frame, an air supply pipe communicating with the air nozzle, and a positioning component connected to the air nozzle. The air nozzle faces the side of the knitting needle's latch near the hook. This invention has the effect of quickly opening the latch to facilitate the entry of spliced ​​yarn into the hook for knitting, thus improving work efficiency. The air nozzle sprays air to open the knitting needle's latch, thereby facilitating the hook of the knitting needle to catch the spliced ​​yarn during operation, thus improving work efficiency.

[0003] However, the air nozzle in the aforementioned patent sometimes fails to open the needle tab after expelling airflow, which can cause problems in the knitting process and reduce production quality. Utility Model Content

[0004] The purpose of this invention is to provide a circular weft knitting machine needle hook adsorption device to solve the above-mentioned problems.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model discloses a circular weft knitting machine needle hook adsorption device, including a vertical rod installed on a frame. Two lifting components are sleeved on the vertical rod, and an adjustment component is installed on the lifting component. The adjustment component includes a crossbar and a fixing block. One end of the crossbar passes through a through hole opened in the fixing block, and the body of the crossbar is fixed in the through hole by a first locking screw. A guide ring is connected to the other end of the upper crossbar, and a magnet is connected to the other end of the lower crossbar.

[0007] Furthermore, the lifting assembly includes a lifting block, which is sleeved on the upright, and a fixing block is connected to the lifting block. The lifting block has a first threaded hole, and a second locking screw is threaded into the first threaded hole. The tail of the second locking screw abuts against the upright.

[0008] Furthermore, both the first locking screw and the second locking screw have butterfly-shaped heads.

[0009] Furthermore, the fixing block is provided with a second threaded hole, which is connected to the through hole. The first locking screw is threaded into the second threaded hole, and the tail of the first locking screw abuts against the body of the crossbar.

[0010] Furthermore, a mounting plate is connected to the end of the lower crossbar, and the magnet is fixed on the mounting plate.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0012] This invention has a simple structure and is easy to operate. It uses a magnet to attract the needle tongue of the needle hook, ensuring the efficiency of the needle tongue opening and improving production quality. Moreover, it uses a lifting component and an adjusting component to adjust the position of the guide ring and the magnet, which is very convenient. Attached Figure Description

[0017] like Figure 1-2 As shown, a circular weft knitting machine needle hook adsorption device includes a vertical pole 1 installed on a frame. Two lifting components are sleeved on the vertical pole 1. Each lifting component includes a lifting block 7, which is sleeved on the vertical pole 1. The lifting block 7 has a first threaded hole, and a second locking screw 8 is threaded into the first threaded hole. The tail of the second locking screw 8 rests on the vertical pole 1.

[0018] An adjustment component is installed on the lifting assembly. The adjustment component includes a crossbar 2 and a fixing block 3. The fixing block 3 is connected to the lifting block 7. One end of the crossbar 2 passes through a through hole opened on the fixing block 3. The body of the crossbar 2 is fixed in the through hole by a first locking screw 4. A guide ring 5 is connected to the other end of the upper crossbar 2, and a magnet 6 is connected to the other end of the lower crossbar 2 by a mounting plate 9.

[0019] The heads of the first locking screw 4 and the second locking screw 8 are both butterfly-shaped.

[0020] The fixing block 3 has a second threaded hole, which is connected to the through hole. The first locking screw 4 is threaded in the second threaded hole, and the tail of the first locking screw 4 is against the body of the crossbar 2.

[0021] The operation process of this utility model is as follows:

[0022] Before starting work, adjust the positions of the guide ring 5 and the magnet 6. After starting work, the needle of the hook is lifted by the triangular top block below, causing several hooks on the equipment to move in a wave-like motion. When the hook rises, the height of the needle tongue is the same as that of the magnet 6. The needle tongue is attracted by the magnet 6. As the hook rises, the attraction of the magnet 6 causes the needle tongue to open. The hook hooks the steel wire passing through the guide ring 5. Then, because the top block has passed, the hook will fall naturally. During this period, the needle tongue is attracted by the magnet 6 again, causing the downward tilted end of the needle tongue to rise due to the attraction, making the needle tongue tilt upward until the hook falls into the syringe and the needle tongue closes.

[0023] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
