Description

Technical Field

[0001] This utility model relates to the field of lining production technology, specifically a warp beam dyeing vat anti-expansion clamp for fabric rolls. Background Technology

[0002] The typical production process for garment linings involves washing and dyeing the greige fabric in an overflow dyeing vat, followed by setting and coating. However, overflow dyeing vats use rope-like dyeing, and linings are relatively thin fabrics, making them prone to pilling and abrasion during the dyeing process. Therefore, some high-quality linings are produced in beam dyeing machines. In beam dyeing, the greige fabric is pre-shrunken and rolled onto a beam drum. Then, depending on whether the dyeing process is internal or external and the width of the fabric roll, the inner and outer baffles of the beam drum are installed to block the small holes on the beam drum that are leaking outside the fabric roll, ensuring that the dye liquor does not leak.

[0003] This dyeing method works well for base fabrics with low elastic elongation, but it is easy for interlinings woven from polyester elastic yarns with high elastic elongation to sag and lose elasticity after dyeing. Polyester is dyed under high temperature and high pressure, with dyeing temperature as high as 130 degrees Celsius. Under these conditions, it is difficult for polyester elastic yarns to shrink back after being stretched, which affects the product style and quality requirements.

[0004] In existing technologies, warp beam dyeing vats only have inner and outer baffles of the warp beam barrel, and no clamping plate for the rolled fabric. In order to maintain the elasticity of elastic fabrics, internal flow dyeing is often used, that is, the dye liquor flows from the outside to the inside of the fabric roll. Because of the weight of the dye liquor and the fabric roll itself, the fabric roll will also sag, which will hinder the circulation of the dye liquor in the fabric roll, resulting in poor dyeing effect, color difference, and affecting the elasticity of the fabric. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a warp roller dyeing cylinder anti-blowing clamp, which can effectively solve the problems of large internal dyeing pressure difference, obstructed circulation of dye liquor in the cloth roll, poor dyeing effect and easy color difference in the prior art, and the cloth roll sagging due to the weight of dye liquor and cloth roll, which affects the elasticity of the fabric.

[0006] The technical solution adopted by this utility model is: a warp beam dyeing vat anti-expansion clamping plate, including a fabric roll body, an anti-expansion clamping plate surrounding the end of the fabric roll body away from the center line, warp beam barrels provided at both ends of the fabric roll body, the anti-expansion clamping plate being composed of side baffles, upper outer clamping plates and lower outer clamping plates, an outer baffle and an inner baffle fixedly installed at the end of the side baffles near the warp beam barrels, filling plates provided on the upper outer clamping plates and the lower outer clamping plates, and small holes of a certain spacing and size opened on the expansion clamping plate.

[0007] Preferably, there are four identical upper and lower outer clamping plates, which are made of 1mm to 2mm thick stainless steel plates. The cross-section of the upper and lower outer clamping plates is arc-shaped and fits snugly against the fabric roll body.

[0008] Through the above technical solution, four upper and lower outer clamping plates are respectively attached to the upper and lower sides of the fabric roll body. The 1mm to 2mm thick stainless steel plate material ensures that the clamping plates have a certain strength and can withstand the pressure generated by the fabric roll during the dyeing process. The "arc" structure fits tightly with the fabric roll body, which can tightly wrap the fabric roll. During the dyeing process, especially for elastic fabrics, it effectively restricts the expansion of the fabric roll, prevents the fabric roll from sagging due to expansion, avoids loss of elasticity, and can also be adjusted according to the diameter and width of the dyed fabric roll.

[0009] Preferably, the upper outer clamping plate and the lower outer clamping plate have positioning holes one and two on their extended portions away from the fabric roll body, and the filling plate has positioning hole three on one end near positioning holes one and two. The upper outer clamping plate, the lower outer clamping plate and the filling plate are threadedly connected by clamping bolts through positioning holes one, positioning holes two and positioning holes three.

[0010] With the above technical solution, after the four upper and lower outer clamping plates are respectively attached to the upper and lower sides of the fabric roll body, the filling plate can be placed in the gap between the upper and lower outer clamping plates, so that positioning hole one, positioning hole two and positioning hole three are aligned. Finally, the clamping bolts are passed through these positioning holes and tightened. The clamping bolts generate a tightening force through the threaded connection, firmly connecting the three together to form a whole. This can effectively prevent the clamping plates from loosening during the dyeing process, ensuring that the fabric roll body is always in a stable clamped state, thereby better playing the role of preventing expansion.

[0011] Preferably, an outer baffle and an inner baffle are fixedly installed at the end of the side baffle away from the fabric roll body, and the width of the outer baffle and the inner baffle is greater than the length of the warp roller and equal to half the length of the warp roller.

[0012] With the above technical solution, before dyeing the warp beam, the greige fabric is first rolled onto the warp beam drum, then the outer baffle and inner baffle are installed on the side baffle, and then the side baffle is installed at both ends of the fabric roll body, working together with the anti-expansion clamp to prevent the fabric roll from expanding and sagging during the dyeing process.

[0013] Preferably, slot 1 and slot 2 are provided through both ends of the upper outer clamping plate and the lower outer clamping plate, and insert plates are fixedly installed on both ends of the filling plate near the upper outer clamping plate and the lower outer clamping plate, and the insert plates are plugged into slot 1 and slot 2.

[0014] Through the above technical solution, by cooperating with the insert plate and slot one and slot two, the filling plate can be easily installed between the upper outer clamping plate and the lower outer clamping plate, which can conveniently and quickly fill the gap between the upper and lower clamping plates, improve installation efficiency, and at the same time play a limiting role.

[0015] Preferably, a reinforcing plate is fixedly installed at one end of the filling plate near the fabric roll body, and the reinforcing plate is in contact with the fabric roll body.

[0016] Through the above technical solution, the contact between the reinforcing plate and the fabric roll body further enhances the clamping ability of the clamp on the fabric roll, effectively suppresses the expansion of the fabric roll, ensures that the fabric roll maintains a good shape during the dyeing process, and improves the dyeing quality.

[0017] Preferably, the side baffle is adapted to the outer baffle and the inner baffle, and the side baffle is located at both ends of the fabric roll body.

[0018] The above technical solution allows for the installation of anti-expansion clamps by using side baffles located at both ends of the fabric roll body. These baffles work together with the anti-expansion clamps to limit the expansion of the fabric roll during the dyeing process and prevent the fabric roll from sagging.

[0019] Compared with the prior art, this utility model provides a warp beam dyeing vat anti-blowing clamp, which has the following beneficial effects:

[0020] 1. This warp roller dyeing vat anti-blowing clamp has four upper and lower outer clamps attached to the upper and lower sides of the fabric roll body. The 1mm to 2mm thick stainless steel plate ensures that the clamp has a certain strength and can withstand the pressure generated by the fabric roll during the dyeing process. The "arc" structure fits tightly with the fabric roll body and can tightly wrap the fabric roll. During the dyeing process, especially for elastic fabrics, it effectively limits the expansion of the fabric roll, prevents the fabric roll from sagging due to expansion, avoids loss of elasticity, and can also be adjusted according to the diameter and width of the dyeing fabric roll.

[0021] 2. The anti-expansion clamp for the warp dyeing cylinder has an outer baffle and an inner baffle installed on the side baffle, which is then installed at both ends of the fabric roll body. Working together with the anti-expansion clamp, it prevents the fabric roll from expanding and sagging during the dyeing process. This avoids the fabric roll sagging, which would obstruct the circulation of dye liquor within the fabric roll, resulting in poor dyeing effect and color difference. Furthermore, the clamping bolts generate a tightening force through threaded connection, which can further prevent the clamp from loosening during the dyeing process, ensuring that the fabric roll body is always in a stable clamped state, thereby better playing the role of anti-expansion.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: As Figure 1-6 As shown, the present invention provides a warp roller dyeing vat anti-blowing clamp, including a fabric roll body 16, an anti-blowing clamp surrounding the end of the fabric roll body 16 away from the center line, warp roller barrels 1 at both ends of the fabric roll body 16, and the anti-blowing clamp is composed of a side baffle 4, an upper outer clamp 5 and a lower outer clamp 8. An outer baffle 2 and an inner baffle 3 are fixedly installed on the side baffle 4 near the warp roller barrel 1, and filling plates 11 are provided on the upper outer clamp 5 and the lower outer clamp 8.

[0031] Specifically, there are four identical upper outer clamping plates 5 and lower outer clamping plates 8. The four upper outer clamping plates 5 and lower outer clamping plates 8 are made of 1mm to 2mm thick stainless steel plates. The cross-section of the upper outer clamping plates 5 and lower outer clamping plates 8 is arc-shaped and fits snugly against the fabric roll body 16. The advantage is that by attaching the four upper outer clamping plates 5 and lower outer clamping plates 8 to the upper and lower sides of the fabric roll body 16 respectively, the 1mm to 2mm thick stainless steel plate material ensures that the clamping plates have a certain strength and can withstand the pressure generated by the fabric roll during the dyeing process. In addition, the arc-shaped structure fits snugly against the fabric roll body 16, which can tightly wrap the fabric roll. During the dyeing process, especially for elastic fabrics, it effectively restricts the expansion of the fabric roll, prevents the fabric roll from sagging due to expansion, and avoids loss of elasticity.

[0032] Specifically, the upper outer clamping plate 5 and the lower outer clamping plate 8 have positioning holes 1-6 and 2-9 on their extended portions away from the fabric roll body 16. The filling plate 11 has a positioning hole 3-14 on one end near the positioning holes 1-6 and 2-9. The upper outer clamping plate 5, the lower outer clamping plate 8, and the filling plate 11 are threadedly connected by clamping bolts 15 through the positioning holes 1-6, 2-9, and 3-14. The advantage is that after the four upper outer clamping plates 5 and 8 are respectively attached to the upper and lower sides of the fabric roll body 16, the filling plate 11 can be placed in the gap between the upper outer clamping plates 5 and 8, so that the positioning holes 1-6, 2-9, and 3-14 are aligned. Finally, the clamping bolts 15 are passed through these positioning holes and tightened. The clamping bolts 15 generate a tightening force through the threaded connection, firmly connecting the three together to form a whole. This can effectively prevent the clamping plates from loosening during the dyeing process, ensuring that the fabric roll body 16 is always in a stable clamped state, thereby better playing the role of preventing expansion.

[0033] Specifically, an outer baffle 2 and an inner baffle 3 are fixedly installed on the side baffle 4 at the end away from the fabric roll body 16. The width of the outer baffle 2 and the inner baffle 3 is greater than the length of the warp beam barrel 1 and equal to half the length of the warp beam barrel 1. The advantage is that before warp beam dyeing, the greige fabric is first rolled onto the warp beam barrel 1, and then the outer baffle 2 and the inner baffle 3 are installed on the side baffle 4. The side baffle 4 is then installed at both ends of the fabric roll body 16, working together with the anti-expansion clamp to prevent the fabric roll from expanding and sagging during the dyeing process.

[0034] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0035] Specifically, slot 1 7 and slot 2 10 are provided through both ends of the upper outer clamping plate 5 and the lower outer clamping plate 8. Insert plates 13 are fixedly installed on both ends of the filling plate 11 near the upper outer clamping plate 5 and the lower outer clamping plate 8. The insert plates 13 are inserted into slot 1 7 and slot 2 10. The advantage is that by cooperating with the insert plates 13 and slot 1 7 and slot 2 10, the filling plate 11 can be easily installed between the upper outer clamping plate 5 and the lower outer clamping plate 8, which can conveniently and quickly fill the gap between the upper and lower clamping plates, improve installation efficiency, and at the same time play a limiting role.

[0036] Specifically, a reinforcing plate 12 is fixedly installed at one end of the filling plate 11 near the fabric roll body 16. The reinforcing plate 12 is in contact with the fabric roll body 16. The advantage is that the contact between the reinforcing plate 12 and the fabric roll body 16 further enhances the clamping ability of the clamp on the fabric roll, effectively suppresses the expansion of the fabric roll, ensures that the fabric roll maintains a good shape during the dyeing process, and improves the dyeing quality.

[0037] Specifically, the side baffle 4 is adapted to the outer baffle 2 and the inner baffle 3. The side baffle 4 is located at both ends of the fabric roll body 16. The advantage is that by the side baffle 4 being located at both ends of the fabric roll body 16, it is easy to install anti-expansion clamps. The side baffle 4 works together with the anti-expansion clamps to limit the expansion of the fabric roll during the dyeing process and prevent the fabric roll from sagging.

[0038] Working principle: During use, the four upper outer clamping plates 5 and lower outer clamping plates 8 are respectively attached to the upper and lower sides of the fabric roll body 16. The 1mm to 2mm thick stainless steel plate material ensures that the clamping plates have a certain strength, which can withstand the pressure generated by the fabric roll during the dyeing process, as well as the "arc". The structure fits snugly against the fabric roll body 16, tightly wrapping the fabric roll. During the dyeing process, especially for elastic fabrics, it effectively limits the expansion of the fabric roll, preventing it from sagging due to expansion and avoiding loss of elasticity. After the four upper outer clamping plates 5 and lower outer clamping plates 8 are respectively attached to the upper and lower sides of the fabric roll body 16, the filling plate 11 can be placed in the gap between the upper outer clamping plates 5 and lower outer clamping plates 8, aligning the positioning holes 1-6, 2-9, and 3-14. Finally, the clamping bolts 15 are passed through these positioning holes and tightened. The clamping bolts 15 generate a tightening force through the threaded connection, firmly connecting the three together to form a whole. This effectively prevents the clamping plates from loosening during the dyeing process, ensuring that the fabric roll body 16 is always in a stable clamped state, thus better playing its anti-expansion role. Before warp beam dyeing, the greige fabric is first rolled onto the warp beam barrel 1, and then the outer baffle plate is... 2 and inner baffle 3 are installed on side baffle 4, and then side baffle 4 is installed at both ends of fabric roll body 16. Working together with anti-expansion clamps, they prevent the fabric roll from expanding and sagging during the dyeing process. Through the cooperation of insert plate 13 with slot 1 7 and slot 2 10, filling plate 11 can be easily installed between upper outer clamp 5 and lower outer clamp 8, which can quickly and easily fill the gap between the upper and lower clamps, improve installation efficiency, and also play a limiting role. Through the contact between reinforcing plate 12 and fabric roll body 16, the clamp's constraint ability on the fabric roll is further enhanced, effectively suppressing the expansion of the fabric roll, ensuring that the fabric roll maintains a good shape during the dyeing process, and improving dyeing quality. Because the side baffle 4 is located at both ends of fabric roll body 16, it is easy to install anti-expansion clamps, and they work together with anti-expansion clamps to limit the expansion of the fabric roll during the dyeing process and prevent the fabric roll from sagging.
