Problems solved by technology
The disadvantage of the above structure is that it is suitable for light-duty narrow-width shuttleless looms. For belt fabrics with a bandwidth of more than 200 mm, the transmission is unstable, the weft needles vibrate, and the self-aligning bearing is easily damaged; the quality of the finished product is low, and it is not suitable for heavy fabrics. suitable

Embodiment Construction
[0019] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0020] Such as figure 1 , figure 2 with image 3 As shown, the embodiment of the present invention provides a weft insertion device, including a machine base 1, a steel sley 2, a connecting rod 3, a guide rod 4, a swing rod 5, a swing arm shaft 6, a swing arm 7 and a weft needle 8.
[0021] The steel sley 2 is fixed on the machine base 1 by the sley feet 9 on both sides of the machine base 1 , and the steel reed 10 is fixed on the steel sley 2 by the steel reed pressing plate 11 .
[0022] The guide rod 4 is fixedly arranged on the base 1 and is parallel to the connecting rod 3 . The two ends of the guide rod 4 are positioned by tensioning sleeves 12, and the two ends of the guide rod 4 are respectively provided with shaft end pressure pads 13, and the shaft end pressure pads 13 compress the tension sleeves 12 under the a...

The invention relates to a wefting insertion device, in particular to a wefting insertion device used for a heavy shuttleless ribbon loom. The device comprises an engine base, a steel sley, a connecting rod, a swing arm shaft, a swing arm and a weft needle, wherein the steel sley is fixed on the engine base through a sley sword; one end of the swing arm is connected with the weft needle, while the other end is connected with the upper end of the swing arm shaft; the wefting insertion device also comprises a guide rod, and the guide rod is fixed on the engine base and parallel with the connecting rod; one end of the connecting rod is connected with the steel sley through a connecting rod seat, while the other end is fixedly connected with a guide bearing block which is arranged on the guide rod and can slide up and down on the guide rod; and the lower end of the swing arm shaft is provided with a swing rod connected with the guide bearing block through a bearing. In the invention, the guide rod fixed on the engine base is used for transmitting the swing power of the weft needle, which can guarantee stable transmission and avoid damage to the bearing because the swinging of the weft needle, thus the wefting insertion stability is improved.
Description
technical field [0001] The invention relates to a weft insertion device for a shuttleless belt loom, in particular to a weft insertion device for a heavyweight shuttleless belt loom. Background technique [0002] What the existing shuttleless loom machine adopts is a kind of space four-link weft insertion mechanism, and it is characterized in that it is made up of sley, self-aligning bearing, nylon connecting rod, mandrel, weft needle swing arm, weft needle seat and weft needle. Composition, the sley is relatively fixed on the reed shaft through screws, the self-aligning bearing is installed in the nylon connecting rod, and the outer figure of the nylon connecting rod is connected concentrically through the bearings at both ends, and one end of the connecting rod is relatively fixed with the steel sley through screws. The other end of the rod and the weft needle swing arm are relatively fixed by screws; the end of the swing arm is connected on the frame through the swing arm...
