Description

[Technical field]

[0001] The present invention relates to the technical field, in particular to a new T-shaped widening ridge, roller and application of the roller. [Background technology]

[0002] In the prior art, there are two types of parts used to expand the opening width of the fabric or film: one is the bending expander roll, and the other is the screw expander roll. When the expander roller is applied to thin fabric, the expanding effect is low because the fabric is slippery and has a small weight. To improve the expanding effect, one solution is to increase the number of expander rollers or increase the contact area. However, although this improves the expanding ability, the fabric is easily damaged due to the radial pulling force being too large or the force being too large in the middle. Another solution is to increase the rotation speed of the expander roller. However, increasing the rotation speed has a high requirement for the radial runout of the expander roller, and if the roller has a large radial runout and causes oscillation, it may cause damage to the fabric. The Chinese patent discloses a T-shaped ridge for an expander roller, in which the cross section of the T-shaped ridge body has an inverted T-shaped structure, and the T-shaped ridge body includes a spreading portion and a connecting portion, the top of the spreading portion has an arc-shaped structure, the top of the connecting portion is connected to the bottom of the spreading portion, and the bottom of the connecting portion has an upwardly curved arc-shaped structure, and the arc-shaped structure at the bottom of the connecting portion is relatively thin. When the material is spirally wound around the surface of the roller, it is pulled flat under the influence of the pulling force caused by the winding and comes into contact with the surface of the roller, and both sides of the connecting portion come into contact with the surface of the roller, and under the action of stress, both sides are firmly attached to the surface of the roller, and the friction force is increased, thereby solving the problem of the slipping of the ridge. However, since the spreading part of the T-shaped convex strip is located in the middle of the connection part, it may prevent the deformation of the arc-shaped structure of the connection part, and in actual application, the bottom of the connection part cannot be made flat to fully contact with the surface of the roller, so the friction force between the spreading convex strip and the surface of the roller cannot solve the problem of the convex strip slipping well, and the spreading convex strip needs to be fixed by discontinuous solder joint, so as to solve the problem of the convex strip slipping and improve the spreading effect, the spreading convex strip and the winding process are improved. Therefore, a new type of spreading convex strip is developed to solve the problem of the convex strip slipping and improve the spreading effect. Summary of the Invention

[0003] In order to solve the above technical problems, the object of the present invention is to provide a new type of T-shaped widening ridge, roller and roller application.

[0004] The widening ridge according to one embodiment of the present invention is a base having a planar or downwardly protruding lower surface; A first expansion portion is vertically connected to the upper surface of the base, an arc-shaped support portion is provided at the top of the first expansion portion, and the cross-sectional area of ​​the first expansion portion is smaller than the cross-sectional area of ​​the base.

[0005] Compared with the prior art, the beneficial effects of the present invention are as follows: the first spreading part is vertically connected to the upper surface of the base, so that the effective spreading height of the spreading ridge is increased, and the contact area between the spreading part and the fabric is increased, thereby improving the spreading effect; compared with the upwardly curved arc-shaped structure when the lower surface of the first spreading part is flat, on the other hand, the cross-sectional area of ​​the first spreading part is smaller than the cross-sectional area of ​​the base, and the spreading ridge can increase the contact area with the roller surface by generating a deformation corresponding to the complete contact of the base with the radian of the roller surface under the action of the tensile force caused by winding; the spreading ridge can be heated before winding, and when the winding is completed, the spreading ridge shrinks with a decreasing temperature, making full use of the thermal expansion and contraction of the spreading ridge and the action of the tensile force caused by winding to form the roll. When the base is in close contact with the surface of the roller and the heating temperature exceeds 400 degrees Celsius, the base may press the groove trace suitable for the base onto the surface of the roller, and the bottom of the base may be engaged with the groove on the surface of the roller. When the lower surface of the first spreading part is a downwardly protruding arc-shaped surface, the protruding arc-shaped surface of the base may be engaged with the groove on the surface of the roller, which further increases the friction force between the spreading ridge and the roller and effectively prevents the ridge from slipping during use, which is an effect that cannot be achieved by an upwardly curved arc-shaped base. In addition, the spreading ridge is in full contact with the surface of the roller to avoid the occurrence of gaps, and keeps the roller and the spreading ridge clean, without affecting the expanding effect of the fabric and the quality of the product. In addition, the top is provided with an arc-shaped support part, which can prevent the spreading ridge from scratching the fabric.

[0006] Furthermore, the width of the base is 5 to 40 mm, and the thickness of the base is 5 mm or less.

[0007] The beneficial effects of adopting the above further technical means are as follows: Increasing the width of the base and decreasing the thickness of the base helps the base to adapt to the radian of the roller surface and generate deformation corresponding to full contact.

[0008] Furthermore, the lower surface of the base, when projecting downward, is an arcuate surface connecting the left side surface and the right side surface, and the arrow height of the arcuate surface is 0.28 mm or less.

[0009] The beneficial effects of adopting the above-mentioned further technical measures are as follows: by controlling the arrow height of the arc-shaped surface to within 0.28 mm, it is possible to prevent the occurrence of gaps due to the inability of the widening convex strip after heating to be completely engaged with the roller surface.

[0010] Furthermore, it further includes a second expansion portion that is provided between the first expansion portion and the support portion, has a conical shape with a larger lower portion and a smaller upper portion, and has one end connected to the support portion and the other end connected to the first expansion portion.

[0011] The beneficial effects of adopting the above-mentioned further technical means are as follows: since the second spreading portion is conical with a larger bottom and a smaller top, firstly, since the side of the second spreading portion is an inclined surface, the contact area between the spreading ridge and the fabric can be further increased and the spreading effect can be improved; secondly, the cross-sectional area of ​​the top of the spreading ridge can be reduced and the tip of the spreading ridge can protrude into the wool layer on the surface of the flannel, thereby greatly improving the spreading effect on the flannel.

[0012] Furthermore, the width of the upper surface of the base is smaller than the width of the lower surface, and the side surface of the base is a flat surface connecting the upper and lower surfaces or an arc-shaped surface protruding upward.

[0013] Furthermore, the side surface of the second expansion portion is an arcuate surface, and the connection portions between the side surface of the second expansion portion and the first expansion portion and the support portion are smooth without any sharp edges.

[0014] The beneficial effects of adopting the above-mentioned further technical measures are as follows: the widening ridge can be prevented from damaging the fabric during operation.

[0015] The beneficial effects of adopting the above-mentioned further technical means are as follows: It is possible to prevent dust from accumulating on the sides of the base and at the connections between the sides and the upper and lower bottom surfaces, which helps to keep the widening ridges clean.

[0016] Furthermore, the width of the first expanding portion is 2 to 25 mm, and / or The radius of the support is 4 to 125 mm, and the distance between the top end of the support and the lower surface of the base is 2 to 18 mm.

[0017] The beneficial effects of adopting the above-mentioned further technical means are as follows: in the specific parameter setting, in order to increase the contact area with the roller surface and maintain a large friction force to avoid the slippage of the ridges, a suitable base is selected according to the expander rollers of different diameters, and the first spreading part is vertically connected to the upper surface of the base, thereby increasing the effective spreading height of the spreading ridges, thereby increasing the contact area between the spreading part and the fabric, and improving the spreading effect. In addition, the radian of the support part is relatively gentle, which prevents the fabric from being scratched during operation.

[0018] A roller according to another embodiment of the present invention has a spiral forward widening ridge and / or a spiral reverse widening ridge on its surface, and the widening ridge is a widening ridge described in any one of the above items.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: The second spreading part is conical with a larger bottom and a smaller top, and the side of the second spreading part is inclined toward the support part, which further increases the contact area between the spreading ridge and the fabric and improves the spreading effect compared to the form in which the vertical first spreading part is directly connected to the arc-shaped support part, and the roller can be in full contact with the roller surface, which increases the friction force between the spreading ridge and the roller and prevents the ridge from slipping.

[0020] Furthermore, the roller includes a tube, the tube including a base tube, the base tube being covered with a stainless steel tube, the tube having a wall thickness of 4 mm or more, and the stainless steel tube having a wall thickness of 0.3 to 3 mm.

[0021] The beneficial effects of adopting the above-mentioned further technical measures are as follows: stainless steel has excellent hot ductility, the widening ridge completes winding at a high temperature while being heated, and a groove that fits the widening ridge is formed on the surface of the roller, so that the protruding arc surface engages with the surface, and the slippage phenomenon of the ridge is avoided.

[0022] Further, a shaft head is provided at each end of the tube, and the shaft head is connected to the inner wall of the roller by a support member, The support member includes a main body, an outer edge of the main body is connected to a connecting portion, and the other end of the connecting portion is connected to a supporting portion, an included angle between the supporting portion and a horizontal plane is an acute angle, and a diameter of a circle enclosed by the outer edge of the supporting portion is larger than a diameter of a circle enclosed by the outer edge of the connecting portion, Alternatively, the support member is a flange plate.

[0023] The beneficial effects of adopting the above-mentioned further technical measures are as follows: the included angle between the support part and the horizontal plane is an acute angle, and when the support member is subjected to a radial external force (such as radial inward pressure, outward pulling force, etc.), the connection part will generate deformation, which will cause the inclination angle of the support part to increase or decrease; when the tube support member penetrates into the tube, it will receive radial pressure from the tube wall, which will cause the inclination angle of the support part to decrease; at this time, the recovery stress of the connection part will not be relieved, and an elastic support will be formed under the action of the recovery stress of the connection part; during design, the diameter of the tube support member can be made larger than the diameter of the tube cavity, and the tube support member can be: After penetrating into the tube, a tight fit is formed, and there is no gap between the tube and the support part, which increases the supporting force of the tube support member on the tube wall, effectively prevents deformation of the tube, provides elastic support, and not only reduces the inclination angle of the support part, but also prevents the tube support member from deforming the tube. During use, if the tube undergoes elastic deformation (such as bending deformation) due to the usage environment, the support part supports the tube by generating adaptive deformation as the tube diameter increases and decreases, thereby preventing plastic deformation of the tube due to repeated elastic deformation, maintaining the roundness tolerance of the tube at the time of shipment, increasing the strength of the expander roller, reducing the weight, and reducing the runout.

[0024] Another aspect of the present invention provides any one of an ironing machine, a spreader, a send-off machine, a folding machine, and a stacker, which applies the above-mentioned roller, and in use, the conventional expander roller can be directly replaced with the expander roller of the present invention to perform the functions of spreading and spreading.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] In order to better understand the technical solution of the present invention, the present invention will be further described below with reference to specific examples and drawings. EXAMPLES

[0027] The new T-shaped widening convex strip of this embodiment is: The base includes a base, the width of the base is 5-40mm, and the thickness of the base is in the range of 0.5-5mm. Increasing the width of the base and decreasing the thickness of the base helps the base to adapt to the radian of the surface of the roller, generate a deformation corresponding to complete contact, and provide a large frictional force to the widening convex strip to prevent the convex strip from slipping. The width of the upper surface of the base is smaller than the width of the lower surface, and the side of the base is a plane connecting the upper surface and the lower surface or an arc-shaped surface protruding upward, there is no gap at the contact point between the widening convex strip and the surface of the roller, the roller and the widening convex strip are kept clean, and the expanding effect of the fabric and the quality of the product are not affected, and the lower surface of the base is a plane or a downward protruding surface, the width of the upper surface of the base is smaller than the width of the lower surface, and the side of the base is a plane connecting the upper surface and the lower surface or an arc-shaped surface protruding upward. As an alternative solution, the lower surface of the base is an arc-shaped surface connecting the left side surface and the right side surface when protruding downward, and the arrow height of the arc-shaped surface is 0.28mm or less. A first expansion portion is vertically connected to the upper surface of the base, the width of the first expansion portion is 2 to 25 mm, the height of the first expansion portion is controlled to 0.5 to 8 mm, an arc-shaped support portion is provided at the top of the first expansion portion, the radius of the support portion is 4 to 125 mm, the distance between the top end of the support portion and the lower surface of the base is 2 to 18 mm, and the cross-sectional area of ​​the first expansion portion is smaller than the cross-sectional area of ​​the base.

[0028] Compared to an upwardly curved arc-shaped structure in which the lower surface of the first expansion portion is flat, on the other hand, the cross-sectional area of ​​the first expansion portion is smaller than the cross-sectional area of ​​the base, and the expansion ridge allows the base to adapt to the radian of the roller surface under the action of the tensile force due to winding, generating a deformation corresponding to complete contact and increasing the contact area with the roller surface. The widening ridge is heated before winding. After winding is completed, the widening ridge shrinks as the temperature decreases, and the thermal expansion and contraction of the widening ridge and the tensile force caused by winding are fully utilized to make close contact with the roller surface. When the heating temperature exceeds 400 degrees Celsius, the base may press a groove trace suitable for the base onto the roller surface. When the bottom of the base is engaged with the groove on the roller surface, and the lower surface of the first spreading portion is a downward protruding arc-shaped surface, the protruding arc-shaped surface of the base will engage with the groove on the roller surface, and outward protrusions will be formed on both sides of the groove trace, which are complementary to the recesses on both sides of the protrusions of the base, thereby not only preventing the ridge from slipping, but also not affecting the beauty of the roller surface. The friction between the widening ridge and the roller is further increased, and the slip phenomenon of the ridge during use is effectively prevented, which is an effect that cannot be achieved by the upwardly curved arc-shaped base. The reason is that the upwardly curved arc-shaped base may cause deformation before and after heating and cooling, and the groove trace formed by heating may cause a gap after cooling. Firstly, it may cause the widening ridge to loosen and reduce the spreading effect. Secondly, the gap may damage the fabric and reduce the spreading effect. Thirdly, the gap may cause the risk of damaging the fabric, which is unacceptable to customers. After the winding is completed, the widening ridge contracts as the temperature decreases and comes into close contact with the surface of the roller, effectively preventing the slip phenomenon of the ridge during use. In addition, the widening ridge is completely in contact with the surface of the roller to avoid the occurrence of a gap, keeping the roller and the widening ridge clean, and not affecting the expanding effect of the fabric and the quality of the product. In addition, the widening ridge is provided with an arc-shaped support at the top, which can prevent the widening ridge from damaging the fabric.

[0029] In order to improve the spreading effect of the new T-shaped expanding ridge on the flannel, the new T-shaped expanding ridge further includes a second expanding ridge between the first expanding section and the support section, which is conical with a large lower part and a small upper part, with one end connected to the support section and the other end connected to the first expanding section, thereby reducing the cross-sectional area of ​​the top of the expanding ridge and allowing the tip of the expanding ridge to protrude into the wool layer on the surface of the flannel, thereby greatly improving the spreading effect on the flannel, and the connection points between the side of the second expanding section and the first expanding section and the support section are smooth, thereby preventing the expanding ridge from damaging the fabric during operation.

[0030] The roller in this embodiment has a spiral forward widening ridge and / or a spiral reverse widening ridge on its surface, and the widening ridge adopts the new T-shaped widening ridge described in any one of the above items.

[0031] In addition, the tube includes a blank tube, the blank tube is covered with a stainless steel tube, and the tube has a wall thickness of 4 mm or more, and the wall thickness of the stainless steel tube is 0.3 to 3 mm, thereby improving the mechanical properties and surface quality of the roller. Since the stainless steel tube has excellent ductility, after the widening ridge is heated, groove traces are pressed onto the roller surface to form anti-slip grooves on the roller surface that fit the anti-slip member, which can help increase the frictional force between the widening ridge and the roller.

[0032] As an optional means, the roller includes a tube, and a shaft head is provided at each end of the tube, and the shaft head is connected to the inner wall of the roller by a support member, the support member includes a main body, and the main body is provided with a shaft hole that fits the shaft head, the outer edge of the main body is connected to a connection part, and the other end of the connection part is connected to a support part, the included angle between the support part and a horizontal plane is an acute angle (the included angle α between the support part and a vertical plane is 90° to 150°), and the diameter of a circle enclosed by the outer edge of the support part is larger than the diameter of a circle enclosed by the outer edge of the connection part, and the support member is a support member of the shaft head. When the support member is fixedly fitted to the outside and is subjected to a radial external force (such as radial inward pressure or outward pulling force), the connection part will deform, causing the included angle between the support part and the horizontal plane to increase or decrease. When the tube support member penetrates the tube, it will be subjected to radial pressure from the tube wall, causing the inclination angle of the support part to decrease. At this time, the recovery stress of the connection part is not released, and the support part forms an elastic support due to the action of the recovery stress of the connection part. When designed, the diameter of the tube support member can be made larger than the diameter of the tube lumen. The tube support member forms an interference fit after penetrating into the tube, and there is no gap between the tube and the support part, which increases the supporting force of the tube support member against the tube wall, effectively prevents deformation of the tube, provides elastic support, and reduces the inclination angle of the support part, as well as preventing the tube support member from deforming the tube. During use, if the tube undergoes elastic deformation (such as bending deformation) due to the usage environment, the support part supports the tube by generating adaptive deformation as the tube diameter increases and decreases, thereby preventing plastic deformation of the tube due to repeated elastic deformation, maintaining the roundness tolerance of the tube at the time of shipment, reducing roller runout, and adapting to high roller rotation speeds.

[0033] The above roller is applied to any one of an ironing machine, a spreader, a send-off machine, a folding machine, and a stacker. In use, the roller of the present invention can directly replace a conventional spreading roller having the same function to perform the functions of expanding and spreading.

Those skilled in the art should understand that the scope of the utility model of the present application is not limited to the technical means formed by the specific combination of the above technical features, and should also include other technical means formed by any combination of the above technical features or their equivalents without departing from the concept of the utility model.
