The automatic drawing-in machine is used as drawing-in equipment with high automation degree, and is widely applied to textile enterprises. The drawing-in speed and drawing-in quality of the automatic drawing-in machine are strongly compared with those of the original manual drawing-in machine, and the development requirement of the modern textile industry is matched. The reed component is an important component of the automatic drawing-in machine, and the reliability and the sensitivity of the reed component determine the working efficiency and the drawing-in quality of the automatic drawing-in machine.
And (3) a reed binding and penetrating process of the automatic penetrating machine: the reed dent of the reed is spread by the reed binding knife, a camera photographs, and then the rapier band carries yarns to pass through the reed dent. At present, as the warp and weft density of high count yarn varieties is high, the quality requirement of cloth covers is continuously improved, so that the cloth covers are uniform in order to pursue the cloth cover style, and the production process reed is forced to develop towards the high density reed process direction. The current automatic drawing-in machine is suitable for the reed below the English system reed number 126, and the efficiency of the reed binding of the reed above the English system reed number 126 is low, so that the production stranding and the disjointing are caused.

It should be noted that in this document, relational terms such as "first" and "second" and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
Referring to fig. 1, an embodiment of the present invention provides a high density reed of an automatic drawing-in machine, which includes a plurality of parallel reed dent pieces, wherein the upper ends and the lower ends of all the reed dent pieces respectively extend into a sheath 3. The reed dent consists of a row of main reed dents 1 and a row of auxiliary reed dents 2, wherein the positions of the main reed dents 1 are fixed, and the upper end and the lower end of the main reed dents 1 are clamped in the sheath 3; a piece of auxiliary reed dent 2 is inserted between every two adjacent main reed dents 1, and the auxiliary reed dent 2 can move towards any main reed dent 1 at two sides under the action of other mechanisms, so that the distance between the auxiliary reed dent 2 and the main reed dent 1 is changed, and the same effect as that of the prior art that a binding reed knife is used for expanding two adjacent reed dents is achieved.
Referring to fig. 2 and 3, a first electromagnet 9 is fixed on top of each auxiliary dent 2, and the first electromagnet 9 includes an upper part and a lower part: the lower part is a coil part 10, i.e. an iron core around the coil; the upper part is an adsorption part 11 made of ferromagnetic material, and is usually designed to be capable of stably magnetically attracting to a target object. A motor 5 is fixed in the sheath 3 above the reed dent, the motor 5 is in driving connection with a lead screw 6, the lead screw 6 is perpendicular to the yarn running direction, specifically, the lead screw 6 is perpendicular to the side face of the reed dent (the surface with the largest area on the reed dent). The screw rod 6 is connected with a nut seat 7 in a matched mode, a guide rod 8 parallel to the screw rod 6 is fixed on the shell of the motor 5, the guide rod 8 penetrates through the nut seat 7 to guide the nut seat 7, and the nut seat 7 can only translate along the axial direction of the screw rod 6. A square tubular moving part 4 is fixed on the nut seat 7, and a screw rod 6 penetrates through the moving part 4.
Referring to fig. 4 and 5, the first electromagnet 9 is connected to a computer, and when the auxiliary reed dent 2 needs to be moved, the computer controls the first electromagnet 9 to be electrified, and the adsorption part 11 of the first electromagnet 9 is stably adsorbed on the moving part 4; when the auxiliary dent 2 does not need to be moved, the computer controls the first electromagnet 9 to be powered off, so that the auxiliary dent 2 is separated from the moving part 4. The motor 5 is also connected to a computer, and under the control of the computer, the motor 5 drives the moving member 4 to precisely move a prescribed distance in a direction perpendicular to the side face of the reed dent.
Referring to fig. 3, two conduits 12 are vertically and fixedly connected to the coil winding portion 10 of the first electromagnet 9, and are respectively used for leading out two ends of the coil. A conductive sheet 13 is fixed to the end of the conduit 12 remote from the first electromagnet 9, and a wire inside the conduit 12 is connected to the conductive sheet 13.

The center of the through hole 18 is provided with a rib rod 25, the spring 19 abuts the clamping block 16 on the rib rod 25, and the rib rod 25 prevents the clamping block 16 from rising further and separating from the through hole 18.
When reed needs to be pricked between two specified adjacent reed dent pieces, the computer is positioned to the position coordinate of one auxiliary reed dent 2, then the computer controls the second electromagnet 17 to be electrified, the clamping block 16 releases the auxiliary reed dent 2, and controls the first electromagnet 9 to be electrified and adsorbed on the moving part 4, the moving part 4 carries the auxiliary reed dent 2 to move towards the direction of the main reed dent 1, thereby expanding the distance between the two reed dent pieces, passing through a rapier band after camera photographing inspection, and finally controlling the auxiliary reed dent 2 to reset by the computer. Because the computer controls the auxiliary dent 2 to move fast, the slow process of expanding two adjacent dents by the binding reed cutter is replaced; because the reed binding knife is not adopted, the reed binding efficiency is less influenced by the improvement of the reed density, and therefore, the higher production efficiency can still be kept in the production process of the high-density reed with the reed number of more than 126.
Referring to fig. 2, the secondary dent 2 and the primary dent 1 have the same structure, and opposite sides in the width direction are respectively straight sides and arc sides. In the height direction, the width (in the yarn running direction) of the sub-dent 2 gradually decreases from the middle to both ends. The arc edge of one row of the auxiliary dents 2 is only partially inserted into the other row of the main dents 1, and the portions of the arc edge of the auxiliary dents 2 near the upper and lower ends are not inserted into the main dents 1.
Referring to fig. 2 and 7, under the side of the reed dent piece (i.e. the view of fig. 7), the top of the arc edge of one row of auxiliary reed dent 2 and the top of the arc edge of the other row of main reed dent 1 enclose a groove 26, and the first elastic piece 20 and the second elastic piece 21 extending into the groove 26 are respectively fixed on the adjacent auxiliary reed dent 2. The first elastic sheets 20 and the second elastic sheets 21 are different in height, and all the first elastic sheets 20 are the same in height and flush, and all the second elastic sheets 21 are the same in height and flush. The first permanent magnet 22 is fixed on the first elastic sheet 20, and the second permanent magnet 23 which is repelled with the first permanent magnet 22 is fixed on the second elastic sheet 21. The side of the sheath 3 is provided with a first camera which photographs the bending of the first and second elastic pieces 20 and 21 at a view angle perpendicular to the side of the reed dent pieces.

When the secondary dent 2 moves to approach the main dent 1, the first permanent magnet 22 and the second permanent magnet 23 repel each other, bending the adjacent first elastic piece 20 and second elastic piece 21 in opposite directions, and the first camera photographs to judge whether the secondary dent 2 starts to move according to whether the first elastic piece 20 and the second elastic piece 21 are bent or not, and whether the secondary dent 2 moves in place according to the maximum degree of bending.
A short time interval exists between two adjacent frames of pictures photographed by one camera, but in this short time interval, the distance of the movement of the secondary dent 2 is not short compared with the minute distance between two adjacent dent pieces of the high density reed, so that one camera easily leaks to photograph the moving picture of the secondary dent 2, and thus it is not possible to accurately check whether the distance between the secondary dent 2 and the main dent 1 after the movement is qualified, so that the first camera and the second camera are arranged to photograph the secondary dent 2 at the same time in such a manner that photographing times are staggered.
The foregoing is only illustrative of the present invention and is not to be construed as limiting thereof, but rather as various modifications, equivalent arrangements, improvements, etc., within the spirit and principles of the present invention.
