Description

Technical Field

[0001] The invention relates to the technical field of textile accessories, in particular to a bobbin which is convenient for cleaning and yarn stripping. Background Art

[0002] In the textile and artificial grass industry, after the yarn or grass yarn is used, most of the winding tubes will still have a small amount of yarn or grass yarn left on them, and these yarns or grass yarns become scraps, which need to be removed from the winding tubes and recycled. The winding tubes that have been cleaned and stripped can be reused.

[0003] Since the yarn or grass silk is reciprocatingly wound on the winding tube, the friction and winding resistance are large, and it is not easy to separate from the winding tube. It is not easy to control the strength by manual cutting, and it is very easy to cut and damage the winding tube. In addition, the cutting efficiency is low, and a large amount of manpower is required, which is too troublesome. Using special machines for cutting or adsorption to separate, firstly, it is impossible to accurately position and fix, and there is a risk of cutting and damaging the winding tube; secondly, it is necessary to configure a special high-power fan, and funds are needed to purchase yarn reversing equipment, which has high costs and energy consumption.

[0004] In short, the current method of cleaning and removing the yarn winding tube is both labor-intensive and labor-intensive, and is likely to cause the winding tube to be cut and damaged, affecting the turnover of the winding tube and increasing production costs. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a winding tube that is easy to clean and remove yarn. The cleaning and removing yarn are easy to operate, and will not cause cuts and damage to the winding tube, thereby eliminating product quality problems caused by cuts on the winding tube and reducing quality costs.

[0006] The present invention is achieved through the following technical solutions:

[0007] Provided is a bobbin winding tube which is convenient for cleaning and yarn stripping. The bobbin winding tube comprises an inner tube and an outer tube. The outer tube is shorter than the inner tube and is composed of a plurality of tube strips spaced from each other. Each tube strip is fixedly connected to the inner tube at one end on the same side. A diameter control component which can cooperate with the end of the tube strip and is used to adjust the outer diameter of the outer tube at this end is installed at one end of the inner tube which is longer than the outer tube.

[0008] As one embodiment of the present invention, the diameter controlling component includes a screw cone sleeve, which includes a cone sleeve having an outer cone surface and a cylindrical sleeve having a diameter the same as the outer diameter of an outer tube. An internal thread is arranged on the inner wall of the cylindrical sleeve, and an end of the inner tube which is longer than the outer tube has an external thread matching the internal thread. An inner wall of the end of each tube strip is formed with an inner cone surface matching the outer cone surface of the cone sleeve.

[0009] The cone part of the spiral cone sleeve is rotated forward and mounted on the inner tube of the winding tube and connected by threads. The outer cone surface fits with the inner cone surface of the outer tube, and the outer diameter of the outer tube is fixed. When it is necessary to remove the residual yarn or grass silk on the outer tube, the spiral cone sleeve is rotated in the opposite direction, the outer cone surface is separated from the inner cone surface of the outer tube, and the outer tube can be contracted inward, and the yarn or grass silk on it can be easily removed.

[0010] As another embodiment of the present invention, the diameter controlling component includes a diameter controlling sleeve, an axial spiral hole is formed on one end surface of the diameter controlling sleeve, a cross-sectional center line of each spiral hole is spiral relative to the center of the diameter controlling sleeve, a pin hole is radially formed on the circumferential surface of the diameter controlling sleeve, an annular groove facing the pin hole is formed at the end of the inner tube which is longer than the outer tube, a pin is inserted into the annular groove in the pin hole, and a fixing column which is inserted into the spiral hole is convexly formed at the end of each tube strip.

[0011] The diameter controlling sleeve is sleeved on the inner tube of the winding tube, the fixing column on the outer tube penetrates into the spiral hole of the diameter controlling sleeve, the pin is assembled and fixed into the pin hole of the diameter controlling sleeve and extends into the annular groove of the inner tube, when the diameter controlling tube is rotated, the short cylinder in the spiral hole is away from the center of the diameter controlling sleeve, the outer diameter of the outer tube of the winding tube is fixed, and the diameter controlling sleeve is rotated in the reverse direction, the distance between the fixing column in the spiral hole and the center of the diameter controlling sleeve is reduced, the diameter of the outer tube is reduced, and the residual yarn or grass silk on it can be easily removed.

[0012] Furthermore, the diameter of the diameter control sleeve is the same as the diameter of the outer tube.

[0013] The diameter of the diameter control sleeve is kept the same as the diameter of the outer tube, so that when the diameter control sleeve is connected to the inner tube and the diameter of the outer tube is fixed, the diameter control sleeve and the outer tube are at the same height, keeping the outer tube in a plane, which is convenient for winding yarn or grass silk.

[0014] Preferably, anti-slip protrusions are formed on the outer periphery of the diameter controlling sleeve.

[0015] The outer periphery of the diameter control sleeve is provided with anti-skid protrusions, so as to increase the friction between the palm and the diameter control sleeve when the diameter control sleeve is rotated, thereby facilitating the operation.

[0016] Furthermore, the tube strips are evenly distributed outside the inner tube at regular intervals, and each tube strip is integrally formed with the inner tube.

[0017] The tube strips are evenly spaced outside the inner tube and form a gap of a certain height between the inner tube and the inner tube, so that they can shrink into the gap when the outer diameter changes. The one-piece molding ensures the overall integrity, facilitates processing and reduces costs.

[0018] Beneficial effects of the present invention:

[0019] The winding tube of the present invention is composed of an inner tube, an outer tube and a diameter control component. The diameter control component cooperates with the tube strip of the outer tube to change the outer diameter of the conventional fixed winding tube into a variable outer diameter, so that the yarn or grass silk on the winding tube can be easily dropped off as the outer diameter of the winding tube shrinks.

[0020] The bobbin winding tube of the present invention is different from the traditional bobbin winding tube, makes up for the shortcomings of the existing operation technology, does not cause cutting and damage to the bobbin winding tube, eliminates the product quality caused by cutting the bobbin winding tube, and reduces the quality cost. By adjusting the diameter of the outer tube, the diameters of the two ends of the outer tube are different, and the residual yarn or grass silk on the bobbin winding tube can be easily separated by manual labor, which saves labor and time and reduces production costs.

[0035] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0036] Embodiment 1:

[0037] like Figure 1-Figure 5 As shown, a winding tube that is convenient for cleaning and yarn stripping comprises an inner tube 6 and an outer tube 1. The outer tube 1 is shorter than the inner tube 6. The outer tube 1 is composed of a plurality of tube strips 7 that are spaced apart from each other, and each tube strip 7 is fixedly connected to the inner tube 6 at one end on the same side, and the other end is open. The tube strips 7 are evenly and equidistantly distributed outside the inner tube 6, and each tube strip 7 is integrally formed with the inner tube 6. The diameter of the outer tube 1 can achieve limited expansion and contraction.

[0038] The end of the inner tube 6 which is longer than the outer tube is provided with a diameter control component which can cooperate with the end of the tube strip 7 and is used to adjust the outer diameter of the outer tube 1 at this end.

[0039] The diameter controlling component comprises a screw cone sleeve 2, which comprises a cone sleeve having an outer cone surface 4 and a cylindrical sleeve having a diameter the same as the outer diameter of the outer tube 1. The inner wall of the cylindrical sleeve is provided with an internal thread 3. The end of the inner tube 6 which is longer than the outer tube 1 has an external thread 8 which matches the internal thread 3. The inner wall of the end of each tube strip 7 is formed with an inner cone surface which matches the outer cone surface 4 of the cone sleeve.

[0040] Assembly relationship: The spiral cone sleeve 2 is screwed onto the open end of the inner tube 6 through the internal thread 3 of the cylindrical part and the external thread 8 at the end of the inner tube 6, and the inner conical surface of the outer tube 1 fits with the outer conical surface 4 of the cone part of the spiral cone sleeve 2.

[0041] During normal use, the outer conical surface 4 of the screw cone sleeve 2 fits with the inner conical surface of the outer tube 1, and the outer diameter of the outer tube 1 is fixed.

[0042] When the residual yarn or grass filaments 5 on the outer tube 7 need to be removed, the spiral cone sleeve 2 is rotated in the opposite direction, the spiral cone sleeve 2 is separated from the inner cone surface of the outer tube 1, and the tube strips 7 of the outer tube 1 can be retracted inwardly, and the yarn or grass filaments 5 thereon can be easily removed.

[0043] Embodiment 2:

[0044] like Figure 6-Figure 12As shown, a winding tube which is convenient for cleaning and yarn stripping is provided, the winding tube comprises an inner tube 6 and an outer tube 1, the length of the outer tube 1 is smaller than that of the inner tube 6, the outer tube 1 is composed of a plurality of tube strips 7 which are spaced apart from each other, and each tube strip 7 is fixedly connected to the inner tube 6 at one end on the same side, the tube strips 7 are evenly and equidistantly distributed outside the inner tube 6, and each tube strip 7 is integrally formed with the inner tube 6.

[0045] The end of the inner tube 6 that is longer than the outer tube 1 is provided with a diameter control component that can cooperate with the end of the tube strip 7 and is used to adjust the outer diameter of the outer tube 1 at this end. The diameter of the outer tube 1 can be expanded or contracted to a limited extent by the diameter control component.

[0046] The diameter control component comprises a diameter control sleeve. The diameter of the diameter control sleeve 10 is the same as the diameter of the outer tube 1 , and anti-slip protrusions 16 are formed on the outer periphery of the diameter control sleeve 10 .

[0047] An axial spiral hole 14 is provided on one end face of the diameter control sleeve 10. The cross-sectional center line of each spiral hole 14 is spiral relative to the center of the diameter control sleeve 10. A pin hole 15 is also radially provided on the circumference of the diameter control sleeve 10. The pin hole 15 is designed as a cylindrical hole. The end of the inner tube 6 longer than the outer tube 1 is provided with an annular groove 13 facing the pin hole 15. The diameter control sleeve 10 is inserted with a pin 11 extending into the annular groove 13 in the pin hole 15. The pin 11 is a column that matches the cylindrical hole. A fixing column 12 that is inserted and matched with the spiral hole 14 is convexly provided at the end of each pipe strip 7.

[0048] Assembly relationship: the diameter control sleeve 21 is sleeved on the open end of the winding tube, the fixing column 12 on the outer tube 1 penetrates into the spiral hole 14 of the diameter control sleeve 10, and the pin 11 is assembled and fixed into the pin hole 15 of the diameter control sleeve 10 and extends into the annular groove 13 of the inner tube 6.

[0049] When the diameter-controlling sleeve 10 is rotated so that the fixing column 12 in the spiral hole 14 is away from the center of the diameter-controlling sleeve 10 , the bobbin is in a normal use state.

[0050] When the diameter control sleeve 10 is rotated in the reverse direction, the distance between the fixing column 12 in the spiral hole 14 and the center of the diameter control sleeve 10 is reduced, that is, the diameter of the outer tube 1 is reduced, and the residual yarn or grass filament 5 thereon can be easily removed.

[0051] The above two embodiments of the present invention can both achieve the purpose of easily removing the residual yarn or straw filament 5 on the winding tube, and can achieve the beneficial effects of saving labor, time and process costs.
