Technical Field
[0001] This utility model belongs to the field of yarn tube technology, specifically relating to a yarn tube runout measuring tool. Background Technology
[0002] Spinning bobbins, also known as yarn tubes or yarn spools, are an indispensable auxiliary material in the textile industry. Yarn bobbins come in various types, including paper tubes, plastic tubes, and steel tubes. Paper tubes, made from paper and glue, are characterized by low cost, ease of processing, and environmental friendliness. Depending on the manufacturing process, paper tubes can be further subdivided into glued paper tubes, coreless paper tubes, core paper tubes, and all-paper tubes. Plastic tubes are made of high-quality plastic and offer advantages such as lightness, durability, corrosion resistance, and easy cleaning. The moderate surface friction of plastic yarn tubes prevents yarn slippage and ensures smooth winding and unwinding. Based on the material, plastic tubes can be further classified as polypropylene plastic tubes, polyethylene plastic tubes, and PET plastic tubes. Steel tubes, made of steel, offer high strength and durability, but are relatively expensive and are mainly used in applications requiring high yarn tube strength.
[0003] Currently, in the production process of existing plastic yarn tubes, the center of the yarn tube is usually hollow. However, the yarn tube needs to be rotated during use. If the inside of the yarn tube deviates from the center during the rotation, the yarn tube will jump. If the jumping amplitude is too large, it will affect the use. However, at present, there is no good yarn tube jumping measuring tool to test the jumping amplitude of the yarn tube, thus affecting the production quality of the yarn tube. Utility Model Content
[0004] The purpose of this invention is to provide a yarn tube runout measuring tool, which aims to solve the problem that in the production process of existing plastic yarn tubes, the center of the yarn tube is usually hollow, but the yarn tube needs to be rotated during use. If the inside of the yarn tube deviates from the center during the rotation, the yarn tube will run out of space. If the runout amplitude is too large, it will affect the use. However, at present, there is no good yarn tube runout measuring tool to test the runout amplitude of the yarn tube, thus affecting the production quality of the yarn tube.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a yarn tube runout measuring tool, including a spindle rod, one end of which is slidably sleeved with a lower fixing ring, and the other end of the spindle rod away from the lower fixing ring is tightly sleeved with an upper fixing ring, the outer wall of the spindle rod is provided with a yarn tube, and one end of the yarn tube is provided with a through-hole.
[0006] As a preferred embodiment of the yarn tube runout measuring tool of this utility model, the outer ring size of the upper fixing ring is larger than the through-hole size, and is adapted to the upper end conical hole diameter of the yarn tube.
[0007] As a preferred embodiment of the yarn tube runout measuring tool of this utility model, the lower fixing ring includes a bearing seat, a spindle bearing, and a bearing cover. The spindle bearing is press-fitted into the hole of the bearing seat, and the bearing cover is located outside the spindle bearing. The spindle bearing and the bearing cover are fixed by rolling the edge of the bearing seat.
[0008] As a preferred embodiment of the yarn tube runout measuring tool of this utility model, the spindle bearing is sleeved on the outer wall of one end of the spindle rod, and its hole diameter is adapted to the outer circle size of one end of the spindle rod.
[0009] As a preferred embodiment of the yarn tube runout measuring tool of this utility model, by axially moving the lower fixing ring, the outer diameter of the protruding part of the bearing seat contacts the lower end hole wall of the yarn tube, thus providing support for the lower end of the yarn tube.
[0010] As a preferred embodiment of the yarn tube runout measuring tool of this utility model, both ends of the yarn tube are sleeved on the outer walls of the lower fixing ring and the upper fixing ring.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] By tightly fitting the upper fixing ring onto one end of the spindle rod, and then fitting the yarn tube onto the upper fixing ring from the same end of the spindle rod, the lower fixing ring is slid onto the outer wall of the spindle rod from the end away from the upper fixing ring. The lower fixing ring will then abut against the tapered hole at the lower end of the yarn tube. The two ends of the spindle rod are then supported by a clamp. At this point, the spindle rod can be rotated manually or by a motor to test the runout amplitude of the yarn tube, and yarn tubes with excessive runout amplitude can be rejected, thus ensuring the quality of the yarn tube.

[0019] 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.
[0020] Please see Figure 1-4 The present invention provides the following technical solution: a yarn tube runout measuring tool, including a spindle 1, a lower fixing ring 2 slidably sleeved at one end of the spindle 1, an upper fixing ring 3 tightly sleeved at the end of the spindle 1 away from the lower fixing ring 2, a yarn tube 4 provided on the outer wall of the spindle 1, and a through opening 5 at one end of the yarn tube 4.
[0021] It should be noted that one end of the spindle 1 passes through the yarn tube 4 through the through-hole 5, and the cross section of the fixing ring 3 sleeved on the spindle 1 is the same as that of the yarn tube 4, which is either an oblique angle or a rounded surface.
[0022] It is also worth noting that the yarn tube 4 used in this application is made of high-quality plastic, which has the advantages of being lightweight, durable, corrosion-resistant, and easy to clean.
[0023] The lower fixing ring 2 includes a bearing seat 21, a spindle bearing 22, and a bearing cover 23. The spindle bearing 22 is press-fitted into the hole of the bearing seat 21, and the bearing cover 23 is located outside the spindle bearing 22. By rolling the edge of the bearing seat 21 to fix the spindle bearing 22 and the bearing cover 23, the outer diameter of the protruding part of the bearing seat 21 contacts the lower end hole wall of the yarn tube 4 by axially moving the lower fixing ring 2, thus providing support for the lower end of the yarn tube 4.
[0024] In practical use, the lower fixing ring 2 can fix one end of the sleeved yarn tube 4, and when used in conjunction with the upper fixing ring 3, the lower fixing ring 2 and the upper fixing ring 3 can hold both ends of the yarn tube 4 together from inside.
[0025] Preferably, the outer ring size of the fixing ring 3 is larger than the through-hole size 5, and the two ends of the yarn tube 4 are sleeved on the outer walls of the lower fixing ring 2 and the upper fixing ring 3.
[0026] In practical use, the yarn tube 4 is inserted into the upper end of the spindle rod 1 along with the upper fixing ring 3 that is tightly connected to it. Then, the lower fixing ring 2 is placed on the outer wall of the spindle rod 1 from the end away from the upper fixing ring 3. At this time, the lower fixing ring 2 will abut against the yarn tube 4, and the other end will be abutted from the inside by the upper fixing ring 3, thereby fixing the yarn tube 4. Then, the two ends of the spindle rod 1 are supported by the clamps, and the spindle rod 1 can be rotated manually or by motor to test the jump amplitude of the yarn tube 4.
[0027] It should be noted that the speed of the motor that drives the spindle 1 to rotate is controlled between 0 and 200 revolutions per minute.
[0028] Working principle: First, the upper fixing ring 3 is tightly fitted onto one end of the spindle rod 1. Then, the yarn tube 4 is fitted onto the upper fixing ring 3 from the same end of the spindle rod 1. Next, the lower fixing ring 2 is fitted onto the outer wall of the spindle rod 1 from the end away from the upper fixing ring 3. At this time, the lower fixing ring 2 will abut against the yarn tube 4, and the other end will be abutted against from the inside by the upper fixing ring 3, thereby fixing the yarn tube 4. Then, the two ends of the spindle rod 1 are supported by clamps. The spindle rod 1 can be rotated manually or by motor at 0-200 rpm to test the runout of the yarn tube 4. Yarn tubes with excessive runout are rejected, thus ensuring the quality of the yarn tube.
[0029] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model.
