Description

Technical Field

[0001] The present invention relates to an auxiliary structure for discharging cloth of a cloth winding machine, and particularly to an improved structure for pressing the cloth during cloth discharging and cutting of a cloth winding machine, which can avoid the tension backhaul before cloth cutting to reduce the virtual damage of the warp and weft of the cloth. Background Art

[0002] For the currently commonly used cloth discharging structure of the cloth winding machine, please refer to Figure 1 As shown, a cloth discharging frame 4 is arranged between the two cloth winding machine support walls 2 below the large circular knitting machine. The power is transmitted when the speed change gearbox 3 rotates, and the cloth is wound in cooperation with the rotation of the large circular knitting machine. When the woven cloth 9 is woven, the cloth support frame 6 arranged above the two cloth winding machine support walls 2 spreads the cylindrical cloth roll, and the cloth is cut into sheet-shaped cloth by the cloth cutting machine 8. Then, a plurality of cloth pulling rods 50 are driven by the cloth guiding gear box 7 arranged below to pull the woven cloth 9 downward, and the sheet-shaped cloth is pulled downward by the cloth guiding frame 51 arranged below through the first cloth guiding rod 21, the second cloth guiding rod 22, the third cloth guiding rod 23, and the fourth cloth guiding rod 24 to be wound on the cloth winding shaft of the cloth discharging frame 4 to form a cylindrical cloth 90; after the cloth 90 is wound to a fixed number of yards, it is cut into a cylindrical cloth 90 by the worker and unloaded from the support of the cloth discharging frame 4, that is, a cylindrical cloth 90 is wound.

[0003] In the disclosure of the currently commonly used cloth winding mechanism of the cloth winding machine, when the cloth 90 is wound to a fixed weight, it must be cut into a cylindrical bundled cloth roll. At this time, whether the cloth 90 is cut between the second cloth guiding rod 22 and the third cloth guiding rod 23 or between the third cloth guiding rod 23 and the fourth cloth guiding rod 24, the woven cloth 9 with a large span area between the upper cloth pulling rod 50 and the cloth support frame 6 will be affected by the tension backhaul from the upper large circular knitting machine, often causing the warp and weft of the woven cloth 9 to become virtual due to tension pulling, and even seriously causing a large amount of damage to the cloth. Therefore, how to reduce the loss of deformation of the large-span warp and weft of the woven cloth 9 is an urgent problem that the textile industry has been thinking about and needs to be improved.

[0004] In view of the above-mentioned disadvantages of the currently commonly used cloth winding mechanism of the cloth winding machine, the inventor studied and improved the solution for the disadvantages, and finally this invention was created. Summary of the Invention

[0005] The main purpose of the present invention is to provide an improved structure for pressing the cloth during cloth discharging and cutting of a cloth winding machine, which can moderately press the cloth with the cloth guiding rod before cloth discharging and cutting of the woven cloth, avoid the warp and weft of the woven cloth from becoming virtual due to the tension backhaul above, and cause a large amount of material loss.

[0006] To achieve the above purpose, the intelligent cloth pressing mechanism of the present invention is connected and interlocked with the large circular knitting machine and the cloth winding machine. The technical means implemented by the present invention include: Among them:

[0007] The intelligent cloth pressing mechanism is composed of a plurality of lower supports, a plurality of pivot seats, a plurality of swing arms, a plurality of lifting mechanisms, and a cloth pressing rod.

[0008] According to the above structure, the plurality of lower supports have a plate-shaped upper plane, which is provided with a first coupling seat and a connecting hole penetrating through it, a second coupling seat and a connecting hole penetrating through it, a plurality of positioning holes, and a plurality of coupling screw holes.

[0009] According to the above structure, the plurality of pivot seats are formed by stamping a plate into a concave shape. One end has a first extension portion above it and a second coupling hole penetrating through it. The other end has a screwing hole, and the concave plane is further provided with a plurality of lifting holes that can correspondingly pivot a plurality of second connecting rods.

[0010] According to the above structure, the plurality of swing arms are bent plate members. One end is provided with a hanging portion and a third coupling hole penetrating through it. The middle section is provided with a second extension portion and a first coupling hole penetrating through it. The other end is provided with a bent portion and a fourth coupling hole penetrating through it.

[0011] According to the above structure, the plurality of lifting mechanisms are connected with a driving component. The lower end is provided with a lower ear portion with a through hole, and the upper end is provided with a telescopic shaft portion with a through hole and is set as an upper ear portion, and is composed of a plurality of first connecting members; and

[0012] According to the above cloth pressing rod, it is pivotally arranged between the swing arms.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] When a plurality of lower brackets, pivot seats, a plurality of swing arms, a plurality of lifting mechanisms, and a cloth pressing rod are sequentially combined, the cloth pressing rod is correspondingly arranged to press the cloth with the third cloth guiding rod on the bracket wall of the cloth winding machine, achieving an improved structure for pressing the cloth during cutting of the lower cloth of the cloth winding machine, so that the warp and weft of the woven cloth are not worried about being pulled back by the upper tension, and reducing material loss.

[0050] When in use, please refer to Figures 5 to 8 As shown, first start the electric control host of the large circular knitting machine and make a power connection with the lifting mechanism 14. If the user observes that the fabric 90 is about to be wound up and needs to cut the lower cloth, first stop the large circular knitting machine, then put the driving assembly 140 of the lifting mechanism 14 in the on mode, and then drive the axis of the lifting mechanism 14 to rise (or fall), so that the hanging portion 131 of the swing arm 13 connected thereto is forced to rise (or fall). The swing arm 13 uses the fourth coupling hole 1321 of the bent portion 132 at the other end as the rotation axis, so that the pressing cloth rod 15 pivotally installed on the second extension portion 133 in the middle section of the swing arm 13 presses upwards against the third fabric guiding rod 23, and the fabric 90 is pressed and fixed with an appropriate tightness. After the fabric 90 is cut, it is then moved away from the fabric winding machine by the lower cloth rack 4. And if it is to adapt to large circular knitting machines and fabric winding machines of different sizes and specifications, only need to replace the pressing cloth rod 15 of different lengths and screw it at the fixed hole 113 of the lower support 11 by the second connecting member 124 to adjust the height between the pivot seat 12 and the third fabric guiding rod 23, then it can be used with fabric winding machines of different specifications. On the contrary, if you want to resume continuous fabric winding operation after cutting the lower cloth, please refer to Figures 7 to 8As shown, the drive assembly 140 of the lifting mechanism 14 is put into the starting state, causing the axis of the lifting mechanism 14 to descend, so that the hanging portion 131 of the swing arm 13 connected thereto begins to lower in height, and by the lever principle, the fourth coupling hole 1321 of the bent portion 132 at the other end of the swing arm 13 is used as the rotation axis, causing the pressing rod 15 pivotally provided at the second extension portion 133 in the middle of the swing arm 13 to lower downward, so as to disengage from the third fabric guide rod 23 to an appropriate gap. First, the end of the uncompressed fabric 90 is wound on the fabric take-up rod (not shown separately in the figure) of the lower fabric stand 4, and then after starting the large circular knitting machine and the fabric winder, the operation of winding the fabric 90 can be started again.
