[0002] When developing new products, in order to avoid affecting normal production and reduce costs, a test machine was set up, modeled after the production line, including textile production equipment such as twisting machines, doubling twisting machines, and dipping tanks. Among them, the twisting machine can also be used as a bobbin rewinding device. However, when rewinding with the existing equipment, only single-sided bobbins can be used. These bobbins are not commonly used and are produced in small quantities, so they need to be purchased separately. However, because they are not used often, purchasing them can easily lead to waste. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a winding bobbin structure for a testing machine, which not only meets the needs of bobbin rewinding but also avoids waste and saves costs.

[0004] The technical solution adopted by this utility model is a winding bobbin structure for a testing machine, including a bobbin core, a bushing and a straight cylinder. The outer diameter of the bobbin core matches the inner diameter of the straight cylinder. The bobbin core is sleeved on the rotating shaft of the twisting machine and the bushing is set above it. The bottom end contacts the turntable of the twisting machine. The straight cylinder is sleeved on the outer side of the bobbin core.

[0005] Furthermore, the aforementioned tube core is made of plastic, the straight tube is made of paper, and the bushing is made of stainless steel.

[0006] Furthermore, the aforementioned tube core includes a circular upper and lower disc, the diameter of which is the same as that of the twisting machine turntable. A left vertical plate and a right vertical plate are symmetrically arranged near the edge between the upper and lower discs. A cross-shaped support frame is provided in the middle of the left and right vertical plates respectively. The outer end face of the support frame is an arc shape that matches the inner wall of the straight cylinder and abuts against the straight cylinder. A circular through hole is opened in the center of the upper and lower discs, and a limiting sleeve is provided on the top face of the lower disc corresponding to the through hole. Support plates are provided around the limiting sleeve, and the outer ends of the two sets of support plates are connected to the left and right vertical plates respectively.

[0007] Furthermore, the aforementioned support frame includes horizontal support plates and vertical support plates, and the length of the horizontal support plate is not less than 2 / 3 of the width of the left vertical plate.

[0008] Furthermore, a reinforcing plate is horizontally connected in the middle of the left and right upright plates, and a circular hole is opened in the center of the reinforcing plate to accommodate the passage of the twisting machine shaft.

[0009] Furthermore, the lower outer sides of the left and right vertical plates are respectively provided with fixing frames. The fixing frames are U-shaped with an arc-shaped outer end face, and are in contact with the inner wall of the straight cylinder.

[0010] Furthermore, the bushing has multiple threaded holes on its sidewall, and bolts are screwed into these holes to connect and fix the bushing to the twisting machine shaft.

[0011] Compared with the prior art, the beneficial effect of this utility model is that by setting the bobbin core to be sleeved on the rotating shaft of the twisting machine turntable, a support body driven by the twisting machine turntable is provided. Then, an existing straight cylinder is sleeved on the bobbin core, and a bushing is set above the bobbin core for fastening. The combination results in a winding bobbin structure that can be used on a twisting machine.

[0016] The present invention will be further explained below with reference to the accompanying drawings to enable those skilled in the art to better understand it.

[0017] Example 1

[0018] like Figure 1-4 As shown, a winding bobbin structure for a testing machine includes a bobbin core 1, a bushing 2, and a straight bobbin 3. The outer diameter of the bobbin core 1 matches the inner diameter of the straight bobbin 3. The bobbin core 1 is sleeved on the rotating shaft 4 of a twisting machine, with the bushing 2 positioned above it. The bottom end of the bobbin core 1 contacts the twisting machine turntable 5. The straight bobbin 3 is sleeved on the outer side of the bobbin core 1. By setting the bobbin core 1 on the rotating shaft of the twisting machine turntable 5, a support body driven by the twisting machine turntable 5 is provided. Then, the existing straight bobbin 3 is sleeved on the bobbin core 1, and the bushing 2 is positioned above the bobbin core 1 for fastening. This combination results in a winding bobbin structure that can be used on a twisting machine. The yarn from the bobbin is directly wound onto the straight bobbin and can be directly used in the next process, which is convenient, quick, saves the cost of purchasing single-sided bobbins, and avoids waste.

[0019] Furthermore, the aforementioned tube core 1 is made of plastic, the straight tube 3 is made of paper, and the bushing 2 is made of stainless steel, so that the tube core straight tube is more stably fitted on the twisting machine shaft.

[0020] Furthermore, the aforementioned bobbin core 1 includes a circular upper plate 101 and a lower plate 102. The diameters of the upper plate 101 and the lower plate 102 are the same as those of the twisting machine turntable 5. A left vertical plate 103 and a right vertical plate 104 are symmetrically arranged near the edge between the upper plate 101 and the lower plate 102. The upper plate 101, the lower plate 102, the left vertical plate 103, and the right vertical plate 104 together constitute the main structure of the bobbin core 1. The left and right vertical plates are not traditionally cylindrical, but have a hollow structure in the middle, which saves materials and reduces weight. The left vertical plate 103 and the right vertical plate 104 are respectively provided with cross-shaped support frames 10 in the middle. 5. The outer end face of the support frame 105 is an arc shape that matches the inner wall of the straight cylinder and abuts against the straight cylinder 3, which is conducive to the straight cylinder 3 being stably fitted on the outside of the tube core. The upper plate 101 and the lower plate 102 have circular through holes in the center, and the top face of the lower plate 102 is provided with a limiting sleeve 106 corresponding to the through hole. The limiting sleeve 106 is surrounded by support plates 107. The outer ends of the two sets of support plates 107 are respectively connected to the left vertical plate 103 and the right vertical plate 104. The limiting sleeve 106 has a guiding function, which is conducive to the quick vertical insertion of the tube core 1 into the twisting machine shaft. The support plates prevent the limiting sleeve from deforming.

[0021] The aforementioned support frame 105 includes a horizontal support plate 1051 and a vertical support plate 1052. The length of the horizontal support plate 1051 is not less than 2 / 3 of the width of the left vertical plate 103, thereby increasing the contact area between the support frame 105 and the straight cylinder and enhancing the stability of the straight cylinder sleeve.

[0022] To enhance the structural strength of the tube core, a reinforcing plate 108 is horizontally connected in the middle of the left vertical plate 103 and the right vertical plate 104. A circular hole is opened in the center of the reinforcing plate 108 to accommodate the passage of the twisting machine shaft 4.

[0023] Furthermore, the lower outer sides of the left vertical plate 103 and the right vertical plate 104 are respectively provided with fixing brackets 109. The fixing brackets 109 are U-shaped and the outer end face is arc-shaped. They are in contact with the lower inner wall of the straight cylinder 3 to increase the connection area with the straight cylinder. They are in contact with the straight cylinder from the bottom to ensure that the straight cylinder is stably fitted outside the tube core.

[0024] Furthermore, the bushing 2 has multiple threaded holes 201 on its side wall. Bolts are screwed into the threaded holes 201 and then connected to the twisting machine shaft to fix the bushing 2. The bushing is used to fix the tube core 1 and the straight tube 3. After the straight tube 3 is wound, the bushing is removed and the straight tube is taken off.

[0025] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from its design spirit and principles should fall within the protection scope defined by the claims of the present invention.
