[0002] During the alkali mercerization pretreatment of fabrics on the clip-type alkali mercerizing machine, the fabrics are dipped in alkali twice and rolled in alkali for full penetration reaction, and then pulled into the expansion area by the back-stage rolling car behind the alkali dipping reaction area.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0036] Please refer to Figure 1 and Figure 2 As shown, a tentering auxiliary device 100 according to an embodiment of the present invention comprises at least one pair of tentering assemblies 110, which are respectively arranged on cloth clip chain tracks 200 on both sides of the mercerizing machine to respectively hold the opposite sides of the fabric.

[0037] The tentering assembly 110 includes a first tentering roller 111 , a second tentering roller 112 , and a mounting seat 115 .

[0038] The first tenter roller 111 includes a first roller column 1112 and a first annular tooth layer 1114 disposed on the side wall of the first roller column 1112. The first annular tooth layer 1114 has a plurality of first annular teeth extending along the circumference of the first roller column 1112 and arranged along the axial direction of the first roller column 1112.

[0039] The second tenter roller 112 includes a second roller column 1122 and a second annular gear layer 1124 disposed on the side wall of the second roller column 1122. The second annular gear layer 1124 has a plurality of second annular teeth extending along the circumference of the second roller column 1122 and arranged along the axial direction of the second roller column 1122.

[0040] The mounting seat 115 is used to be arranged on the cloth clip chain track 200, the first tenter roller 111 is movably connected to the mounting seat 115, the second tenter roller 112 is used to be connected to the cloth clip chain track 200, and is arranged opposite to the first tenter roller 111, and the first annular teeth and the second annular teeth are staggered. The tenter assembly 110 can move synchronously with the cloth clip chain track 200.

[0041] Since the first stretching roller 111 is movably connected to the mounting seat 115 , the first stretching roller 111 can approach the second stretching roller 112 so that the first annular tooth layer 1114 and the second annular tooth layer 1124 are embedded in each other to cooperate in clamping the side of the fabric, or move away from the second stretching roller 112 .

[0042] The above-mentioned tentering auxiliary device 100 includes at least one pair of tentering assemblies 110, which are respectively arranged on the cloth clip chain tracks 200 on both sides of the mercerizing machine, so that the tentering assemblies 110 can move synchronously with the cloth clip chain tracks 200. When working, the side of the fabric is placed on the first tentering roller 111 and the second tentering roller 112, so that the first tentering roller 111 is close to the second tentering roller 112, and the first ring tooth layer 1114 and the second ring tooth layer 1124 are embedded to cooperate in clamping the side of the fabric. The side of the fabric is pressed between the two teeth, which can increase the tension of the two side areas of the fabric, so that the warp yarn density of the two side areas of the fabric is close to or consistent with the warp yarn density of the middle part of the fabric, thereby reducing or eliminating the color difference in the edge of the fabric caused by the different amount of alkali solution in the middle and both sides of the fabric.

[0043] In one example, the first ring tooth layer 1114 has 5 to 10 first ring teeth, and the second ring tooth layer 1124 has 5 to 10 second ring teeth. In a specific example, the first ring tooth layer 1114 has 7 first ring teeth, and the second ring tooth layer 1124 has 8 second ring teeth.

[0044] In one example, the height of the first ring gear layer 1114 is 1 cm to 3 cm. The height of the second ring gear layer 1124 is 1 cm to 3 cm. In a specific example, the heights of the first ring gear layer 1114 and the second ring gear layer 1124 are both 1.5 cm.

[0045] In one example, the tooth top of the first annular tooth has a smooth transition. In one example, the tooth root of the first annular tooth has a smooth transition. In one example, the tooth top of the second annular tooth has a smooth transition. In one example, the tooth root of the second annular tooth has a smooth transition. The smooth surface of the annular tooth can avoid damage to the fabric.

[0046] In the specific example shown in the figures, first tenter roller 111 is disposed above second tenter roller 112 .

[0047] like Figure 2 As shown, in one example, the tentering assembly 110 further includes a rotating arm 113, which is rotatably connected to the mounting seat 115, and one end of the first tentering roller 111 is connected to the rotating arm 113. In this way, by rotating the rotating arm 113 at a certain angle, the first tentering roller 111 is driven to move, so that the first tentering roller 111 is close to or away from the second tentering roller 112. By adjusting the angle of rotation of the rotating arm 113, the distance between the first tentering roller 111 and the second tentering roller 112 can be adjusted. When the first annular gear layer 1114 and the second annular gear layer 1124 are embedded, the closer the distance between the first tentering roller 111 and the second tentering roller 112 is, the greater the tension applied by the two to the corresponding parts of the fabric. The angle value of the rotation of the rotating arm 113 can be determined according to the production process.

[0048] Furthermore, if Figure 3 and Figure 4 As shown, in one example, the tenter assembly 110 further includes a rotating support 114. The rotating support 114 is connected to the rotating arm 113, and the rotating support 114 has a convex arc surface. The mounting seat 115 has an embedding groove 1152, and the groove bottom of the embedding groove 1152 is a concave arc surface adapted to the convex arc surface, and the rotating support 114 is embedded in the embedding groove 1152. It can be understood that the convex arc surface takes the center of the mounting hole 1132 as the center of the circle. In this way, the rotating support 114 can stably support the rotating arm 113.

[0049] like Figure 1As shown, in one example, the tentering auxiliary device 100 further includes an angle adjustment assembly. The angle adjustment assembly includes a first mounting bracket 121, a second mounting bracket 122, a mounting rod 123, and a rotating component 124. The first mounting bracket 121 and the second mounting bracket 122 are used to be respectively arranged on the outer sides of the cloth clip chain tracks 200 on both sides. The two ends of the mounting rod 123 are respectively mounted on the first mounting bracket 121 and the second mounting bracket 122. The mounting rod 123 is located above the first tentering roller 111. The rotating component 124 is connected to the mounting rod 123 to drive the mounting rod 123 to rotate. The rotating arm 113 is provided with a mounting hole 1132, and the mounting rod 123 passes through the mounting hole 1132. When the mounting rod 123 rotates, it can drive the rotating arm 113 to rotate, thereby adjusting the distance between the first tentering roller 111 and the second tentering roller 112. The rotating arm 113 can move along the mounting rod 123 to ensure that the tentering assembly 110 can move synchronously with the cloth clip chain track 200.

[0050] The cross section of the portion of the mounting rod 123 used to match the mounting hole 1132 is non-circular, and optionally, the cross section may be, but is not limited to, a polygon, an ellipse, etc. The shape and size of the mounting hole 1132 are adapted to the mounting rod 123, so that when the mounting rod 123 rotates, it can apply a torsional force to the rotating arm 113, driving the rotating arm 113 to rotate. The polygon may be a triangle, a quadrilateral, a pentagon, etc. In the specific example shown in the figure, the cross section of the portion of the mounting rod 123 used to match the mounting hole 1132 is a square.

[0051] like Figure 5 As shown, in one example, the rotating component 124 includes a rotating lever 1241 and a pushing driver 1242. The rotating lever 1241 is connected to the mounting rod 123. The pushing driver 1242 is connected to the rotating lever 1241 to push the rotating lever 1241, thereby rotating the mounting rod 123.

[0052] In one example, the push driver 1242 is a servo electric cylinder, which can control the extension amount of the telescopic member of the push driver 1242 to control the rotation angle of the rotating lever 1241. The telescopic member of the push driver 1242 is rotatably connected to the rotating lever 1241, such as hinged.

[0053] Furthermore, in one example, the rotating component 124 further includes a rotation angle indicator 1243, which cooperates with the rotating lever 1241 to indicate the rotation angle of the rotating lever 1241. In this way, it is convenient for the operator to control the rotation angle of the rotating lever 1241. One end of the rotating lever 1241 is a pointed end, which cooperates with the rotation angle indicator 1243 to accurately indicate the rotation angle of the rotating lever 1241.

[0054] like Figure 5 As shown, in one example, the rotating component 124 further includes a limiter, which is disposed on one side of the rotating lever 1241 and is used to limit the rotation angle of the rotating lever 1241 .

[0055] The above example sets a limiter to limit the rotation angle of the rotating lever 1241, thereby preventing the first stretching roller 111 from being out of position due to operational errors, thereby preventing damage to the machine.

[0056] like Figure 5 As shown, in one example, the rotating component 124 also includes a displacement sensor 1245 and a controller. The displacement sensor 1245 can be a telescopic displacement sensor. The displacement sensor 1245 is rotatably connected to the rotating lever 1241. The displacement sensor 1245 is used to detect the moving distance of the position where the rotating lever 1241 is connected to the displacement sensor 1245, so as to know the rotation angle of the rotating lever 1241. The controller is electrically connected to the moving sensor and the push driver 1242. When the moving sensor detects that the moving distance of the rotating lever 1241 reaches the set value, the controller controls the push driver 1242 to stop the action.

[0057] The above example can conveniently adjust the rotation angle of the rotating lever 1241 by setting a displacement sensor 1245 and a controller (not shown in the figure). In addition, it can also be used to limit the rotation angle of the rotating lever 1241, thereby preventing the first stretching roller 111 from being out of position and causing damage to the machine due to operational errors.

[0058] In the specific example shown in the figures, the rotating component 124 is mounted on the first mounting bracket 121 .

[0059] like Figure 1 As shown, in one example, the tentering auxiliary device 100 further includes a support assembly. The support assembly includes a support rod 131 and a support sleeve 132. The two ends of the support rod 131 are respectively mounted on the first mounting bracket 121 and the second mounting bracket 122, the support rod 131 is located above the mounting rod 123, the support sleeve 132 is connected to the support rod 131, and is sleeved on the mounting rod 123, and the support sleeve 132 is located between a pair of tentering assemblies 110 in the horizontal direction.

[0060] In the above example, by providing a support assembly, the support sleeve 132 can generate a pulling force on the mounting rod 123 to support the mounting rod 123 and prevent the mounting rod 123 from being bent and deformed due to being too long or having insufficient rigidity.

[0061] Furthermore, in one example, the support rod 131 is provided with a threaded hole extending in the vertical direction, and the support assembly also includes a height adjustment bolt 133, which cooperates with the threaded hole, and one end of the height adjustment bolt 133 is connected to the support sleeve 132 for adjusting the height of the support sleeve 132.

[0062] In the above example, by providing a height adjustment bolt 133 , which cooperates with the threaded hole of the support rod 131 , the tension formed by the support sleeve 132 on the mounting rod 123 can be adjusted to better support the mounting rod 123 .

[0063] like Figure 1 As shown, in one example, the tentering auxiliary device 100 further includes a spray assembly. The spray assembly includes a spray pipe 141 and a spray nozzle 142. The spray pipe 141 is mounted on the first mounting bracket 121 and the second mounting bracket 122, and the spray pipe 141 is located above the mounting rod 123. The spray nozzle 142 is arranged on the spray pipe 141, and the spray nozzle 142 is used to spray a lubricating liquid on the mounting rod 123. The lubricating liquid can be an alkali solution.

[0064] The above example sets a spray assembly to spray lubricating liquid on the mounting rod 123 to reduce the friction between the hole wall of the mounting hole 1132 and the mounting rod 123, so that the rotating arm 113 can move smoothly on the mounting rod 123, ensuring smooth stretching work.

[0065] In one example, there are multiple spray nozzles 142 , and the multiple spray nozzles 142 are distributed along the spray pipe 141 .

[0066] Furthermore, the present invention also provides a mercerizing machine, comprising a cloth passing channel, a cloth clip chain track and the auxiliary stretching device 100 described in any one of the above embodiments, wherein the cloth clip chain track is respectively arranged on both sides of the cloth passing channel.

[0067] The above-mentioned mercerizing machine has any of the above-mentioned auxiliary stretching devices 100, so that the corresponding technical effects can be obtained.

[0068] The present invention is further described below by using a specific example.

The rotating component 124 is connected to the mounting rod 123 to drive the mounting rod 123 to rotate. The rotating arm 113 is provided with a mounting hole 1132, and the mounting rod 123 passes through the mounting hole 1132. The cross-section of the portion of the mounting rod 123 used to cooperate with the mounting hole 1132 is square. When the mounting rod 123 rotates, it can drive the rotating arm 113 to rotate, thereby adjusting the distance between the first tenter roller 111 and the second tenter roller 112.
