Description

Technical Field

[0001] This utility model relates to the field of fabric processing equipment, and in particular to a traction device for a stenter and setting equipment. Background Technology

[0002] In the fabric production process, after processes such as scouring, bleaching, and dyeing, the fabric undergoes a process of stretching in the warp direction and shrinking in the weft direction; this process is called stretching. In the stretching step, the traction device usually uses fabric clips to fix and pull a large area of ​​fabric. Existing traction devices use feed plates and discharge plates at the feed and discharge ends, respectively. At the feed position, the feed plate sequentially opens the fabric clamps, inserts the fabric, and closes the clamps. At the discharge position, the discharge plate sequentially opens the fabric clamps and removes the fabric. However, the existing feed plate and discharge plate structures are inconsistent. Using different structures for feed and discharge increases installation difficulty, complicates assembly processes, and raises maintenance costs. Especially when the fabric production line is adjusted, the traction device, which can only transport in one direction, may fail to open the clamps if transported in the opposite direction due to the different structures of the feed plates. Therefore, the feed plate and discharge plate often need to be replaced, requiring lengthy debugging before normal production. This necessitates prolonged downtime, impacting production efficiency and reducing the flexibility of the traction device. Utility Model Content

[0044] like Figure 1-4 A traction device for a stenter equipment, comprising: a clip feeding device 01;

[0045] The pair of clipping devices 01 are distributed on the left and right, forming a hollow area 11 between them;

[0046] The clip feeding device 01 includes: a drive box 1, a frame 2, a conveyor chain 3, a support plate 4, a clip placement assembly 5, and a multi-directional plate 6;

[0047] The conveyor chain 3 is rotatably mounted on the frame 2, and the conveyor chain 3 is equipped with a plurality of the cloth clamping assemblies 5. The support plate 4 is rotatably mounted on the frame 2 and is located at both ends of the conveyor chain 3. The drive box 1 is used to drive the conveyor chain 3 and the support plate 4 to rotate clockwise or counterclockwise respectively.

[0048] The clamping assembly 5 includes: a main body 51, a rotating sleeve 52, a clamping plate 53, and a swing plate 55;

[0049] The main body 51 is provided with a clamping bar 511, the bottom of the rotating sleeve 52 is equipped with the clamping plate 53, and the back of the rotating sleeve 52 is equipped with the swing plate 55; the rotating sleeve 52 is rotatably mounted on the main body 51, and a clamping opening 500 with clamping function is formed between the clamping plate 53 and the clamping bar 511.

[0050] The multi-directional plate 6 is horizontally arranged in the hollow area 11 and is located at both ends of the conveyor chain 3. The multi-directional plate 6 has a beveled edge 611 on one side and a vertical edge 612 on the other side. The multi-directional plate 6 is movably and adjustablely connected to the frame 2 so that the beveled edge 611 or the vertical edge 612 can be adjusted to be close to the clamping bar 511.

[0051] When the inclined edge 611 approaches the clamping strip 511, the inclined edge 611 extends into the upper surface of the clamping strip 511, and the inclined edge 611 drives the rotating sleeve 52 to rotate, causing the swing plate 55 to swing up, and the clamping opening 500 opens; after passing the multi-directional plate 6, the swing plate 55 falls and rests on the outer periphery of the support plate 4.

[0052] When the vertical edge 612 approaches the clamping strip 511, the vertical edge 612 horizontally abuts against the side of the clamping strip 511, and the upper surface of the multi-directional plate 6 is horizontally aligned with the upper surface of the clamping strip 511; after passing the multi-directional plate 6, the swing plate 55 disengages from the support plate 4 and drives the clamping plate 53 to swing to the upper surface of the support plate 4, and the clamping jaw 500 retracts.

[0053] This solution provides a traction device for a tenter frame, which has multi-directional plates 6 positioned before and after the hollow area 11 between the feeding clamp devices 01. The multi-directional plates 6 have inclined sides 611 and vertical sides 612. The multi-directional plates 6 can be adjusted so that the inclined sides 611 or vertical sides 612 are close to the clamping strip 511 as needed. The clamping jaws 500 of the inclined sides 611 or vertical sides 612 can be adjusted to be in an open or closed state at the position of the clamping strip 511, thereby simplifying the structure of the feeding clamp device 01 and allowing the conveying direction of the traction device to be switched as needed. This solves the problem of the complex structure caused by the need to use multiple plates to adjust the opening and closing of the clamping jaws 500 in the feeding clamp device 01 of the existing tenter frame, and the problem of low flexibility in the use of the traction device of the tenter frame.

[0054] Specifically, the feeding clamp devices 01 are distributed on the left and right sides, forming a perforated area 11 for accommodating the fabric. The fabric is clamped by the clamps 500 of the feeding clamp devices 01 on the left and right sides, and transferred from one end (feeding end) of the perforated area 11 to the other end (unfeeding end) by the conveyor chain 3. Figure 1The arrow indicates the direction of fabric conveying; the drive box 1 is replaced by a known mechanism with a drive rotation function, which mainly drives the support plate 4 to rotate and also drives the conveyor chain 3 to rotate; the support plate 4 is located at both ends of the conveyor chain 3, and the drive box 1 can be equipped with a motor, or a combination of a motor and a reducer, to directly or indirectly drive the support plate 4 to rotate; the conveyor chain 3 is a ring chain, and the drive box 1 can be equipped with gears, through at least one pair of gears meshing with the conveyor chain. When the conveyor chain 3 and gears are driven to rotate, the conveyor chain 3 can move in the straight section of the hollow area 11, thereby driving multiple clamping assemblies 5 to move linearly in the hollow area 11. During operation, the drive box 1 drives the conveyor chain 3 to rotate cyclically, causing multiple clamping assemblies 5 to move. When the clamping assembly 5 moves the first half circle, it moves from the loading end to the unloading end. When the clamping assembly 5 moves the second half circle, it returns from the unloading end to the loading end. The traction device cannot be fitted with any other plate other than the multi-directional plate 6. The multi-directional plate 6 is adapted for both loading and unloading. The multi-directional plate 6 of this application can be adjusted in a known way, such as rotating or moving in the X, Y, and Z axis directions. The multi-directional plate 6 is horizontally set, with a sloping edge 611 on one side and a vertical edge 612 on the other side. Therefore, after adjustment, the sloping edge 611 or the vertical edge 612 of the multi-directional plate 6 can be moved closer to the clamping bar 511. Since the same multi-directional plate 6 has different functional structures in different positions, such as Figure 1 One of the multi-directional plates 6 has a slanted edge 611 that can be close to the clamping bar 511 at one end of the conveyor chain 3, and the other multi-directional plate 6 has a vertical edge 612 that can be close to the clamping bar 511 at the other end of the conveyor chain 3, so that the multi-directional plate 6 at the feeding end is used for feeding and the multi-directional plate 6 at the discharging end is used for discharging.

[0055] Initially, the swing plate 55 rests against the outer periphery of the support plate 4; the upper surface of the multi-directional plate 6 is horizontally aligned with the upper surface of the clamping strip 511, and the fabric clamp assembly 5 opens at the clamping opening 500 at the feeding end; at this time, the end of the fabric can be placed on the top surface of the clamping strip 511 of the main body 51, such as... Figure 1 .like Figure 2 The vertical edge 612 is horizontally close to the side of the clamping strip 511, which minimizes the gap between the multi-directional plate 6 and the clamping opening 500. The fabric is placed on the upper surface of the multi-directional plate 6 and the upper surface of the clamping strip 511. The fabric clamp assembly 5 continues to move to the lower end until the swing plate 55 no longer abuts against the outer periphery of the support plate 4. Under the action of gravity, the swing plate 55 falls, the clamping plate 53 returns to its original position close to the clamping strip 511, the clamping opening 500 contracts and clamps the end of the fabric, and the clamping opening 500 conveys the fabric to the lower end in the fabric conveying direction. When the fabric clamp assembly 5 moves to the multi-directional plate 6 at the lower end, such as Figure 3After the corner of the clamping plate 53 contacts the multi-directional plate 6, under the guidance of the inclined side 611, the multi-directional plate 6 pushes the clamping plate 53 inward. The clamping plate 53 swings along the hinge of the rotating sleeve 52 until it is raised. The rotating sleeve 52 rotates and drives the swinging plate 55 to swing upward. Then the conveying chain 3 continues to convey, causing the swinging plate 55 to be raised and rest against the outer periphery of the support plate 4, and the clamping opening 500 opens. At this time, the fabric can be taken out of the clamping opening 500, so that the fabric can be output to the stretcher dryer. Thus, the traction device completes the conveying of the fabric. Then the fabric clamping assembly 5 returns.

[0056] Furthermore, when the system needs to be adjusted for a specific product model so that the fabric conveying direction needs to be changed, this solution does not require overall angle adjustment. Instead, it only needs to adjust the angle and installation position of the multi-directional plate 6 to quickly adapt to the process direction, avoiding large-scale disassembly and relocation of the equipment.

[0057] In some embodiments, a counterweight 54 is mounted on the back of the clamping plate 53; the clamping plate 53 swings along the hinge of the rotating sleeve 52, and the counterweight 54 swings with the clamping plate 53; when the swinging plate 55 does not abut against the outer periphery of the support plate 4, the swinging plate 55 and the clamping plate 53 are reset under the action of the counterweight 54.

[0058] Alternatively, the clipping device 01 may further include: an adjustable component 7;

[0059] The movable adjustment assembly 7 includes: a connecting arm 71, a base 72, and a lifting mechanism 73;

[0060] One end of the connecting arm 71 is movably and adjustablely connected to the frame 2, and the other end of the connecting arm 71 is rotatably and adjustablely connected to the base 72; the lifting mechanism 73 is installed on the base 72, and the lifting mechanism 73 is adjustablely and vertically connected to the multi-directional plate 6.

[0061] The base 72 of the connecting arm 71 is angle-adjustable, thereby driving the lifting mechanism 73 to rotate, so that the inclined edge 611 or vertical edge 612 of the multi-way plate 6 is relatively close to the clamping strip 511. The lifting mechanism 73 is vertically connected to the multi-way plate 6 to adjust the height of the multi-way plate 6, so that the multi-way plate 6 is raised or lowered until the inclined edge 611 extends into the upper surface of the clamping strip 511, or so that the upper surface of the multi-way plate 6 is horizontally aligned with the upper surface of the clamping strip 511. When it is necessary to adjust the angle and position of the multi-way plate 6, the position and angle of the connecting arm 71 can be adjusted, or the lifting end of the lifting mechanism 73 can be adjusted, so that the multi-way plate 6 can be flexibly adjusted at multiple angles.

[0062] Alternatively, the frames 2 of the two clipping devices 01 are connected by a connecting frame 02; the connecting frame 02 is provided with a fixing surface 21; the base 72 is detachably connected to the fixing surface 21.

[0063] The connecting frame 02 is set in the hollow area 11. The connecting frame 02 connects the left and right clamping devices 01 into one unit. In addition, the connecting frame 02 also has the function of fixing the movable adjustment component 7. Specifically, after the base 72 moves at multiple angles with the connecting arm 71, the multi-directional plate 6 is finally adjusted to be close to the clamp 500. Then the base 72 can be fixed to the fixed surface 21, thereby locking the position of the base 72 and restricting the horizontal movement of the base 72. Finally, only the lifting end of the lifting mechanism 73 needs to be adjusted.

[0064] The base 72 is fixed to the fixing surface 21, which can be achieved by known methods, such as screw fixing, snap-fit ​​fixing, clamp fixing, magnetic fixing, etc.

[0065] Optimally, the lifting mechanism 73 includes: a screw 731 and a nut 732;

[0066] The base 72 is provided with a lifting adjustment plate 721, and the lifting adjustment plate 721 is provided with an elongated hole 722; the screw 731 is movably passed through the elongated hole 722; the upper end of the screw 731 is connected to the bottom surface of the multi-directional plate 6; a pair of nuts 732 are threadedly engaged with the screw 731 and are respectively located above and below the elongated hole 722, and the two nuts 732 together limit the screw 731 to the lifting adjustment plate 721.

[0067] The screw 731 has an external thread structure, and the nut 732 has an internal thread structure. A pair of nuts 732 are threadedly engaged with the screw 731, and the nuts 732 clamp the lifting adjustment plate 721, thereby limiting the screw 731, which passes through the elongated hole 722, to the lifting adjustment plate 721. At the same time, in this embodiment, the nuts 732 can be adjusted to increase the distance between the nuts 732, thereby loosening the clamping of the lifting adjustment plate 721. Since the screw 731 can move through the elongated hole 722, the relative position and height position of the screw 731 in the elongated hole 722 can be adjusted so that the multi-directional plate 6 is in the designated position. Then, the distance between the nuts 732 is adjusted to decrease, and the nuts 732 clamp the lifting adjustment plate 721, thereby limiting the position of the multi-directional plate 6 to near the clamping bar 511. Meanwhile, the upper end of the screw 731 is connected to the bottom surface of the multi-directional plate 6. The upper surface of the multi-directional plate 6 is unobstructed, which can prevent other structures on the upper surface of the multi-directional plate 6 from affecting the feeding and discharging.

[0068] Optimally, the lifting mechanism 73 includes: a limiting pin 74;

[0069] The fixing surface 21 is provided with a fixing hole 22; when the base 72 is rotated to the point where the elongated hole 722 is vertically aligned with the fixing hole 22, the limiting pin 74 is detachably inserted into the elongated hole 722 and the fixing hole 22, so that the base 72 is limited to the fixing surface 21.

[0070] When the base 72 rotates to the point where the elongated hole 722 is vertically aligned with the fixed hole 22, the lower end of the limiting pin 74 can pass through the elongated hole 722 and the fixed hole 22 in sequence. The limiting pin 74 restricts the position of the base 72 and the fixed surface 21, thereby restricting the horizontal movement of the base 72 and ensuring that the base 72 will not swing during the operation of the traction device.

[0071] Alternatively, the multi-directional plate 6 may be provided with a gripping opening 613.

[0072] When adjusting the angle of the multi-way plate 6, the grip opening 613 can be held manually, making it easier to operate.

[0073] Optimally, some of the elongated holes 722 are longitudinal elongated holes 7221, and some of the elongated holes 722 are transverse elongated holes 7222, with the longitudinal elongated holes 7221 and the transverse elongated holes 7222 extending in different directions.

[0074] The elongated hole 722 can be divided into a transverse elongated hole 7222 and a longitudinal elongated hole 7221 according to the direction of its angular extension. The screw 731, nut 732 and limiting pin 74 can be installed in the transverse elongated hole 7222 or the longitudinal elongated hole 7221 as needed. For example, the screw 731 can be limited to move in the transverse elongated hole 7222 or the longitudinal elongated hole 7221. Therefore, the movement of the screw 731 in the transverse elongated hole 7222 or the longitudinal elongated hole 7221 can enable the multi-way plate 6 to achieve micro-adjustment, and the multi-way plate 6 has a larger adjustment space.

[0075] Optimally, it also includes: the pressure-down component 8;

[0076] The pressing assembly 8 includes: a pressing base 81, a pressing screw 82, a moving base 83, a pressing wheel 84, and a rotation driver 85;

[0077] The lower pressure seat 81 is disposed on the frame 2, the lower pressure screw 82 is rotatably mounted on the lower pressure seat 81, the movable seat 83 is threadedly engaged with the lower pressure screw 82, the rotation driver 85 is used to drive the lower pressure screw 82 to rotate, thereby driving the movable seat 83 to rise and fall above the lower pressure screw 82; the lower pressure wheel 84 is rotatably mounted on the movable seat 83.

[0078] In this embodiment, if the swing plate 55 gets stuck and cannot be reset or is not reset properly during operation, the swing plate 55 will still be in an inclined state. When the clamping assembly 5 passes the pressing assembly 8, the pressing wheel 84 will press down the swing plate 55 to make it in a straight state. The pressing screw 82 can be driven to rotate by the rotating driver 85, thereby driving the moving seat 83 of the pressing screw 82 to move up and down, thereby adjusting the height position of the pressing wheel 84. The adjustment is convenient and applicable to a wide range of scenarios.

[0079] Alternatively, the pressing component 8 may further include: a horizontal guide rail 86;

[0080] The horizontal guide rail 86 is installed on the frame 2 and extends along the straight direction of the conveyor chain 3; the lower pressure seat 81 is movably installed on the horizontal guide rail 86 and passes between the two support plates 4.

[0081] This solution eliminates the need for multiple pressing components 8, requiring only a single horizontal guide rail 86. When the fabric conveying direction changes to swap the positions of the feeding end and the unloading end, this embodiment can drive the pressing seat 81 to move along the horizontal guide rail 86, moving the pressing seat 81 closer to the feeding end, so that the pressing wheel 84 can press down on the swing plate 55 when the swing plate 55 disengages from the support plate 4.

[0082] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
