Description

Technical Field

[0001] The invention belongs to the technical field of cloth production, and in particular relates to a continuous desizing device for cloth. Background Art

[0002] Desizing is the process of treating fabric with acids, alkalis, enzymes, or other agents to remove the sizing agent added to the warp yarn during weaving. Because sizing can affect the wettability of the fabric during the dyeing and finishing process and hinder the contact of chemicals with the fabric, most fabrics undergo this desizing step.

[0003] Chinese invention patent CN107313192B discloses a high-efficiency desizing machine, comprising a frame, a desizing area, a stacking area, and a cleaning area. The desizing area includes a desizing trough and a padder located at the lower end of the frame. The stacking area includes a first variable-frequency roller, a second variable-frequency roller, and a cloth transport track located between the first and second variable-frequency rollers. The cleaning area includes rollers and a water washing tank. The cloth to be processed is first immersed in a desizing enzyme in the desizing area, then decomposed in the stacking area, and finally washed in the cleaning area to complete the desizing process. The high-efficiency desizing machine disclosed in this patent changes the desizing machine structure, increases the desizing enzyme decomposition time, and improves the rinsing effect of the water washing tank, thereby increasing desizing efficiency and improving product quality. However, the desizing effect and speed of the high-efficiency desizing machine disclosed in this patent still need further improvement, and its overall dimensions are relatively large. Summary of the Invention

[0004] One object of the present invention is to solve or alleviate the above technical problems.

[0005] The means adopted by the present invention is a continuous desizing device for fabric, which includes a desizing box, a stretching roller, a roller frame assembly and at least two fixed rollers; the roller frame assembly includes a fixed roller frame, a reciprocating power member and a stretching roller frame linearly slidably connected to the fixed roller frame, the fixed rollers are hinged to the fixed roller frame in a horizontal row, the fixed roller frame is fixed relative to the desizing box, and the stretching rollers are hinged to the stretching roller frame in a horizontal row and are all located below the fixed rollers; the reciprocating power member has the power to reciprocate and rise and fall and is fixedly connected to the stretching roller frame.

[0006] The present invention has the effect of improving the effect and speed of desizing cloth, thereby miniaturizing the continuous desizing device for cloth while maintaining the same desizing effect and speed.

[0007] A further technical solution is that the fixed roller frame is fixedly provided with an upper crossbeam, and the fixed rollers are all arranged on the upper crossbeam; the fixed rollers include rollers inside the box and rollers outside the box, and the rollers outside the box include the rollers closest to the outside of the box and the rollers farthest from the outside of the box; the reciprocating power part is U-shaped as a whole and one end is fixedly connected to the stretching roller frame.

[0008] This technical solution facilitates maintenance of the roller frame assembly and the reciprocating power device.

[0009] A further technical solution also includes a cloth fixing structure; the cloth fixing structure includes a pressing part and a pressed part facing the pressing part, the pressed part is fixed relative to the desizing box, the pressing part has lifting power and is respectively arranged at the cloth output end and the cloth input end, and the cloth passes between the pressing part and the pressed part.

[0010] This technical solution enables the fabric in the desizing box to be stretched in a stationary state, thereby ensuring the stretching effect and desizing effect on the fabric.

[0011] A further technical solution is that the cloth fixing structure also includes a compression elastic part and a compression power frame provided with a compression part connecting end. The compression power frame has lifting power, and the compression part is provided with a compression part guide rod linearly slidably connected to the compression power frame. The compression elastic part is respectively connected to the compression part and the compression part connecting end, so that the compression part has a tendency to move away from the compression part connecting end; the compression part and / or the compression part connecting end is provided with a compression part limiter for limiting the maximum distance between the two.

[0012] This technical solution can ensure that the pressing piece and the pressed piece firmly clamp the cloth, and can ensure that the cloth in the desizing box is stretched in a static state, and can ensure the stretching effect and desizing effect on the cloth.

[0013] A further technical solution is that the reciprocating power member is provided with an extension body, which is fixedly connected to the compression power frame; or when viewed from above, there is an overlapping portion between the extension body and the compression power frame, and the extension body is in contact with the compression power frame.

[0014] According to a further technical solution, the reciprocating power member is provided with an extension body, and when viewed from above, there is an overlapping portion between the extension body and the compression power frame, and there is a gap between the extension body and the compression power frame.

[0015] This technical solution can improve the degree of change between the cloth being relaxed and being stretched, thereby improving the desizing effect; it can also make it easier for the cloth drooping at the cloth input end to pass through the stretching roller and the fixed roller and then move to the adjustment roller, thereby improving reliability.

[0016] A further technical solution is that a compacting power frame guide rod is provided on the desizing box, the compacting power frame is linearly slidably connected to the compacting power frame guide rod and has a tendency to move upward, and a compacting power frame limiter is provided on the compacting power frame guide rod to resist the compacting power frame.

[0017] This technical solution can ensure that the compacting power frame can be reliably lifted and lowered, and can more conveniently define the position of the compacting power frame to ensure a gap between the extension body and the compacting power frame.

When the pressing part and the pressed part clamp the cloth, the adjustment roller rises and releases the cloth.

[0019] This technical solution can stretch and desize the fabric without affecting the overall uniform speed of fabric transportation, and has high versatility.

[0020] A further technical solution also includes an adjustment rod, which includes an adjustment roller shaft connecting end, a hinged portion and an upward power end.

DETAILED DESCRIPTION

[0034] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0035] As a specific embodiment, the continuous desizing device for fabrics according to the embodiment of the present invention includes a desizing box 8 , a stretching roller 2 , a roller frame assembly 3 and at least two fixed rollers 1 .

[0036] The desizing box 8 is used to contain the desizing liquid of the prior art (usually containing desizing enzymes, etc.), and the interior of the desizing box may also be provided with the prior art fluid jets, ultrasonic devices, desizing liquid circulation filtering devices, etc.

[0037] The roller frame assembly 3 includes a fixed roller frame 31, a reciprocating power member 33, and a stretching roller frame 32 linearly slidably connected to the fixed roller frame 31. For example, the fixed roller frame 31 and the stretching roller frame 32 are connected through a stretching roller frame guide device 329 which is a linear guide rail, thereby realizing a linear sliding connection between the two.

[0038] The fixed rollers 1 are hinged in a horizontal row on the fixed roller frames 31 (i.e., the plane passing through the axis of each fixed roller 1 is a horizontal plane). The fixed roller frames 31 are fixed relative to the desizing box 8. For example, the fixed roller frames 31 are fixed to the inner wall of the desizing box 8 by means of a mounting frame 319 and screws. It is easy to understand that the fixed roller frames 31 can also be provided integrally with the desizing box 8, or can be fixed to the outside of the desizing box 8 by means of a frame (not shown in the drawings).

[0039] The stretching rollers 2 are hinged in a horizontal row on the stretching roller frame 32 and are all located below the fixed roller 1. It is easy to understand that when there are only multiple stretching rollers 2, the plane passing through the axis of each stretching roller 2 is a horizontal plane; but when there is only one stretching roller 2, the plane passing through the axis of the stretching roller 2 can also be a horizontal plane. Therefore, the horizontal row hinge includes the case where there is only one stretching roller 2.

[0040] The reciprocating element 33 is powered by reciprocating motion and is fixedly connected to the stretching roller frame 32. It is connected to a reciprocating power device (not shown) such as a pneumatic cylinder, electric cylinder, or a mechanism that converts rotation into linear motion, providing the reciprocating motion. For narrow fabric 9 and a narrow roller (i.e., fixed roller 1 or stretching roller 2), hinged connection at only one end is usually sufficient. However, for wider fabric 9, hinged connection at both ends is generally required to ensure strength.

[0041] The working principle is that the fabric 9 to be desized passes through the fixed roller 1 and the stretching roller 2 in sequence from the fabric input end (that is, the fabric 9 passes through each roller in the order of fixed roller 1, stretching roller 2, fixed roller 1, stretching roller 2, and fixed roller 1, forming a W-shaped shape. The same applies to more rollers). As the fabric 9 moves from the fabric input end to the fabric output end, the stretching roller frame 32 drives the stretching roller 2 to rise and fall back, so that the fabric 9 between the fixed roller 1 and the stretching roller 2 is stretched back and forth (of course, the stretching of the fabric 9 does not exceed the maximum stretching of the fabric to ensure that the fabric 9 does not break) and then recovers. The fiber pores in the fabric 9 are also stretched and expanded back and forth and then recover, making it easier for the desizing liquid to enter the interior of the fabric 9, thereby improving the desizing effect and speed of the fabric 9. Under the premise of maintaining the same desizing effect and speed, the continuous fabric desizing device can be miniaturized.

[0042] As one specific embodiment, the fixed roller frame 31 is fixedly provided with an upper crossbeam 311, and the fixed rollers 1 are all arranged on the upper crossbeam 311; the fixed rollers 1 include the inner roller 11 and the outer roller 12, and the outer roller 12 includes the closest outer roller 121 and the far outer roller 122; the closest outer roller 121 is the fixed roller 1 closest to the desizing box 8 among the outer rollers 12, and the far outer roller 122 is the roller other than the closest outer roller 121 among the outer rollers 12, for example, the far outer roller 122 is a conveying roller arranged in a subsequent process. The fixed roller frame 31 fixes the inner side wall of the desizing box 8; the reciprocating power member 33 is generally U-shaped (with the two ends being the stretching roller frame connection end 332 and the power device connection end 333 respectively), and one end is fixedly connected to the stretching roller frame 32. The roller frame assembly 3, the fixed roller shaft 1, and the stretching roller shaft 2 are an integral whole. The installation can be completed by simply fixing the fixed roller shaft frame 31 to the inner wall of the desizing box 8. Conversely, the roller frame assembly 3 can be removed from the desizing box 8 for maintenance. The reciprocating power device (cylinder, etc.) that requires frequent maintenance can be set outside the desizing box 8 for easy maintenance, thereby facilitating maintenance of the roller frame assembly 3 and the reciprocating power device.

[0043] As one of the specific embodiments, the continuous desizing device for fabric in an embodiment of the present invention further includes a fabric fixing structure 4; the fabric fixing structure 4 includes a pressing member 41 and a pressed member 42 facing the pressing member 41, the pressed member 42 is fixed relative to the desizing box 8, for example, the pressed member 42 is provided with a mounting groove 421, the side wall of the desizing box 8 is embedded in the mounting groove 421 and is locked by a screw (not shown in the drawing), so that the pressed member 42 is fixed relative to the desizing box 8, the pressing member 41 has a lifting power and is respectively arranged at the fabric output end and the fabric input end, and the fabric 9 passes between the pressing member 41 and the pressed member 42. During the downward movement of the stretching roller frame 32 to stretch the fabric 9 for desizing, the pressing member 41 and the pressed member 42 clamp the fabric 9 so that the fabric 9 between the fabric output end and the fabric input end stops moving, preventing the fabric 9 from slipping on the fixed roller 1 and / or the stretching roller 2. This allows the fabric 9 in the desizing box 8 to be stretched while stationary, ensuring the stretching and desizing effects on the fabric 9. The initial state of the pressing member 41 is that it is in contact with or slightly abutting the fabric 9, ensuring that the fabric 9 can be quickly stopped when the pressing member 41 descends; or the initial state of the pressing member 41 is that there is only a small gap between it and the fabric 9.

[0044] As one of the specific implementations, the cloth fixing structure 4 also includes a compression elastic member 414 and a compression power frame 43 provided with a compression member connecting end 431. The compression power frame 43 has a lifting power. The compression member 41 is provided with a compression member guide rod 413 that is linearly slidably connected to the compression power frame 43. The compression elastic member 414 is respectively connected to the compression member 41 and the compression member connecting end 431, so that the compression member 41 has a tendency to move away from the compression member connecting end 431; the compression member 41 and / or the compression member connecting end 431 is provided with a compression member limiter 415 for limiting the maximum distance between the two. For example, the pressing member limiter 415 is a disk provided at the top of the pressing member guide rod 413. The pressing member limiter 415 abuts against the pressing member connecting end 431 to limit the maximum distance between the pressing member 41 and the pressing member connecting end 431. For another example, the pressing member limiter 415 is an L-shaped hook (not shown in the drawings of this embodiment) provided on the pressing member connecting end 431. The L-shaped hook abuts against the pressing member 41. The elastic force provided by the compression elastic member 414 can ensure that the pressing member 41 and the pressed member 42 firmly clamp the fabric 9. For the embodiment in which the pressing member 41 is driven by the reciprocating power member 33, after the pressing member 41 and the pressed member 42 firmly clamp the fabric 9, the stretching roller shaft frame 32 is allowed to continue to descend, thereby ensuring that the fabric 9 in the desizing box 8 is stretched while stationary, thereby ensuring the stretching effect and desizing effect on the fabric 9.

[0045] As one of the specific implementations, the reciprocating power member 33 is provided with an extension body 334, which is fixedly connected to the compression power frame 43 (not shown in the drawings of this implementation); or when viewed from above, the extension body 334 and the compression power frame 43 have overlapping parts, and the extension body 334 is in contact with the compression power frame 43 (not shown in the drawings of this implementation).

[0046] As one specific embodiment, the reciprocating power member 33 is provided with an extension body 334. When viewed from above, the extension body 334 and the pressing power frame 43 have overlapping portions, and a gap exists between the extension body 334 and the pressing power frame 43. During operation, the extension body 334 moves downward from the highest point until it passes through the gap between the extension body 334 and the pressing power frame 43 (in this process, although the stretching roller frame 32 synchronously descends, the cloth 9 is still in a relaxed state as described later), so that the extension body 334 is in contact with the pressing power frame 43 (at this time, the cloth 9 is in a normal state without being stretched; if the stretching roller frame 32 continues to move downward, the cloth 9 will be stretched); then the extension body 334 continues to move downward and presses the pressing power frame 43 to move downward, so that the cloth 9 is stretched until the cloth 9 is stretched to its maximum extent. Then the extension body 334 begins to reset, specifically, the stretching roller frame 32 drives the stretching roller 2 to move upward until the cloth 9 returns to its normal state without being stretched, and then the stretching roller frame 32 drives the stretching roller 2 to continue to move upward, and the extension body 334 also resets to the highest point with the stretching roller frame 32, and a gap is generated between the extension body 334 and the pressing power frame 43. When the extension body 334 is located in the gap between the extension body 334 and the pressing power frame 43 (i.e., the process from the extension body 334 being at the highest point to the extension body 334 being in contact with the pressing power frame 43, and the process from the extension body 334 being in contact with the pressing power frame 43 to the extension body 334 being at the highest point), the cloth 9 between the cloth output end and the cloth input end is in a relatively relaxed state, which can increase the degree of change of the cloth 9 from being relaxed to being stretched, thereby improving the desizing effect; and can also make the cloth 9 (shown by line LINE1) that droops at the cloth input end described later easier to pass through the stretching roller 2 and the fixed roller 1 and then move to the adjustment roller 5 described below, thereby improving reliability.

[0047] As one of the specific implementations, a compression power frame guide rod 432 is provided on the desizing box 8. The compression power frame 43 is linearly slidably connected to the compression power frame guide rod 432 and has a tendency to move upward. The compression power frame guide rod 432 is provided with a compression power frame limiter 433 that abuts against the compression power frame 43. For example, a spring (not shown in the drawings) is sleeved on the compression power frame guide rod 432. The two ends of the spring respectively abut against the bottom ends of the compression power frame 43 and the compression power frame guide rod 432, so that the compression power frame 43 has a tendency to move upward, which can ensure that the compression power frame 43 can be reliably raised and lowered, and it is more convenient to limit the position of the compression power frame 43 to ensure the gap between the extension body 334 and the compression power frame 43.

[0048] As one of the specific implementations, the continuous desizing device for fabrics in the embodiment of the present invention further includes an adjustment roller 5 provided at the fabric output end; the adjustment roller 5 is located below the fixed roller 1 and has a reciprocating power in the lifting direction, for example, the adjustment roller 5 is driven by a cylinder to be able to lift vertically, or the adjustment roller 5 can swing back and forth in a circular arc and has a reciprocating power in the lifting direction. Figure 9 As shown, when the pressing member 41 and the pressed member 42 clamp the cloth 9, the adjustment roller 5 rises and releases the cloth 9. It is easy to understand that the entire cloth 9 usually maintains a uniform conveying speed (as shown by arrow ARR1), and when the pressing member 41 and the pressed member 42 clamp the cloth 9, the cloth 9 at the pressing member 41 will stop moving. Figure 9 As shown by line 1, when the pressing member 41 and the pressed member 42 corresponding to the cloth input end clamp the cloth 9, the cloth 9 will sag due to continued movement. Figure 9 As shown by line 2, when the pressing member 41 and the pressed member 42 corresponding to the fabric output end clamp the fabric 9, the adjustment roller 5 rises and releases the fabric 9, allowing the fabric 9 to continue to be transported as a whole. Afterwards, when the pressing member 41 and the pressed member 42 corresponding to the fabric input end and the fabric output end, respectively, release the fabric 9, the adjustment roller 5 descends and pulls the fabric 9, so that the fabric 9 drooping at the fabric input end is stored on the adjustment roller 5. Repeating this process eliminates the need for other devices (such as an intermittent unwinding device) to adjust the fabric 9 to intermittent motion. This allows the fabric 9 to be stretched and desized without affecting the uniform speed of the entire fabric 9, resulting in high versatility. When the pressing member 41 and the pressed member 42 corresponding to the cloth input end clamp the cloth 9, the length of the cloth 9 hanging down at the cloth input end is roughly equal to the length of the cloth 9 stored at the adjustment roller 5 after the pressing member 41 and the pressed member 42 corresponding to the cloth output end release the cloth 9. Therefore, in order to adjust the length of the cloth 9 stored at the adjustment roller 5 after the pressed member 42 releases the cloth 9 so that it is equal to the length of the cloth 9 hanging down at the cloth input end, the rising stroke or path of the adjustment roller 5 can be adjusted. For example, the adjustment roller 5 is arranged at the output end of a pneumatic cylinder or an electric cylinder (not shown in the drawings), which is vertically arranged and the stroke is adjusted by means of limit or the like, thereby realizing the adjustment of the rising stroke or path of the adjustment roller 5; of course, the adjustment roller 5 can also be provided with reciprocating power in the lifting direction through the embodiment described below.

[0049] As one of the specific embodiments, the continuous desizing device of the fabric of the embodiment of the present invention further includes an adjusting rod 51, the adjusting rod 51 includes an adjusting roller shaft connecting end 511, a hinge portion 512 and an upward power end 513, the adjusting roller 5 is arranged at the adjusting roller shaft connecting end 511, the hinge portion 512 is hinged to the fixed roller shaft frame 31 (for example, with the upper beam 311) or the desizing box 8 (the embodiment hinged to the desizing box 8 is not drawn), and the upward power end 513 is driven and connected to the compacting power frame 43. In other words, the compacting power frame 43 can drive the upward power end 513 to move it, for example, the upward power end 513 is connected to the compacting power frame 43 against the top to achieve two-way drive (the drawings of this embodiment are not drawn, for example, refer to Figure 8 , the upturned pressure rod 514 on the upturned power end 513 is embedded in the long hole horizontally opened on the pressing power frame 43), that is, when the pressing power frame 43 rises, the upturned power end 513 rises synchronously, and when the pressing power frame 43 falls, the upturned power end 513 falls synchronously. Figure 9 As shown, the pressing power frame 43 moves downward, so that the pressing member 41 and the pressed member 42 clamp the cloth 9 while also causing the adjustment roller 5 to tilt upward. There is no need to set up a power device for driving the adjustment roller 5 and a corresponding PLC or other electronic control device, which can reduce costs and improve reliability.

[0050] As one specific embodiment, the continuous desizing device for fabric in an embodiment of the present invention further includes a reset elastic member 515. The upward power end 513 is provided with an upward pressed rod 514 that abuts against the pressing power frame 43. One end of the reset elastic member 515 is connected to the adjustment rod 51, and the other end is connected to the fixed roller frame 31 or the desizing box 8, so that the adjustment roller shaft connecting end 511 and the adjustment roller shaft 5 have a tendency to move downward. For example, the reset elastic member 515 is a spring and its two ends are respectively connected to the adjustment roller shaft connecting end 511 and the desizing box 8, so that the adjustment roller shaft connecting end 511 and the adjustment roller shaft 5 have a tendency to move downward, which can further improve reliability. Compared with the embodiment described above in which the upward power end 513 is connected to the pressing power frame 43 to achieve bidirectional drive, this embodiment uses the reset elastic member 515 to make the adjustment roller connecting end 511 and the adjustment roller 5 have a tendency to move downward, so that the force of the adjustment roller 5 pressing the cloth 9 downward is easier to adjust and controllable, and can avoid the pressing power frame 43 rising and causing the adjustment roller 5 to move downward with an uncontrollable force and damage the cloth 9.
