Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a tension guide wheel for a twisting machine that is easy to replace. Background Technology

[0002] In the field of textile machinery technology, a doubling machine is a twisting device, essentially a yarn-combining device (combining multiple strands into one), also called a yarn-combining machine. A doubling machine mainly consists of a power unit, a doubling unit, and a transmission unit.

[0003] The existing tension guide rollers of the twisting machine are relatively complicated to disassemble. When workers need to disassemble, maintain or replace them, it often takes a lot of time, which greatly reduces the efficiency of the workers and makes them less practical. Utility Model Content

[0008] Preferably, the base is provided with an auxiliary component, the auxiliary component including: a slide groove, which is opened on the front surface of the housing and two of them are symmetrically opened; a pull plate, in which a pull plate is slidably connected inside each slide groove and each pull plate is fixedly connected to the front surface of the limiting block on the same side.

[0009] Preferably, each of the pull plates is provided with a guide rail cover.

[0010] Preferably, each of the plates has bolts symmetrically arranged at its bottom, and each bolt is inserted into the bottom of the U-shaped plate and threadedly connected to the U-shaped plate.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a tension guide roller for a twisting machine that is easy to replace, and has the following advantages: This invention has the advantage of easy disassembly and replacement of the tension guide wheel. When it is necessary to disassemble and replace the tension guide wheel body, the operator presses the limiting blocks on both sides until the limiting blocks on both sides are completely moved out of the limiting groove on the same side plate. At this time, the limiting on both sides plate is released, thereby releasing the limiting on the U-shaped plate.

[0014] 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.

[0015] Example 1 See Figures 1-4A replaceable tension guide roller for a doubling machine includes a main body assembly 1; the main body assembly 1 includes a base 11 on which a U-shaped plate 12 is disposed; a tension guide roller body 13 rotatably connected to the inner side of the U-shaped plate 12; a disassembly assembly 2 is disposed on the base 11, the disassembly assembly 2 including: a housing 21 fixedly connected to the top of the base 11; two mounting grooves 22 symmetrically disposed on the outer side wall of the housing 21; a limiting block 23 slidably connected inside each mounting groove 22; a spring 24 disposed on each limiting block 23; a plate 25 symmetrically disposed at the bottom of the U-shaped plate 12; a limiting groove 26 penetratingly disposed on each plate 25; a damper 5 disposed on each limiting block 23; and an inclined surface disposed on one side of each limiting block 23.

[0016] When ready for use, the operator installs the base 11 in the designated position on the twisting machine. When it is necessary to disassemble and replace the tension guide wheel body 13, the operator presses the two side limit blocks 23 by hand, causing the two side limit blocks 23 to move deeper into the mounting groove 22 in the housing 21, so that the two side limit blocks 23 squeeze the spring 24 on them respectively. Then the operator continues to squeeze the two side limit blocks 23 until the two side limit blocks 23 are completely removed from the limit groove 26 on the same side plate 25. At this time, the limitation on the two side plates 25 is released, thereby releasing the limitation on the U-shaped plate 12. This allows the operator to disassemble the U-shaped plate 12 together with the tension guide wheel body 13 at the same time. The operation is simple and convenient for replacing the tension guide wheel body 13, improving the practicality of the device. When the device is used or subjected to external force, causing the device to vibrate, the limit blocks 23 will be released. The locating block 23 slides under the action of the spring 24. At this time, the damper 5 reciprocates with the vibration structure through the damping rod, driving the piston to move in the cylinder filled with hydraulic oil. The small holes or gaps on the piston force the hydraulic oil to pass through, generating viscous resistance and internal friction between fluid molecules, converting the vibration kinetic energy into heat energy for dissipation, thus reducing the vibration of the locating block 23. This prevents the locating block 23 from sliding out of the locating groove 26, which would cause the device to be unstable and improve the stability of the device. When the operator installs the tensioning guide wheel body 13, he picks up the U-shaped plate 12 to move the tensioning guide wheel body 13, and at the same time moves the two side plates 25, so that the two side plates 25 press the inclined surfaces on the two side locating blocks 23 respectively, so that the two side locating blocks 23 move automatically under force, without the need for the operator to press manually, thus improving the operator's work efficiency.

[0017] Example 2 See Figures 1-4 Based on Embodiment 1, auxiliary functions have been added; The base 11 is provided with an auxiliary component 3, which includes: a sliding groove 31, which is opened on the front surface of the housing 21, and two of them are symmetrically opened; a pull plate 32, which is slidably connected inside each sliding groove 31, and each pull plate 32 is fixedly connected to the front surface of the limiting block 23 on the same side; a guide rail cover 4 is provided on each pull plate 32; and bolts 6 are symmetrically provided at the bottom of each plate 25, and each bolt 6 is inserted into the bottom of the U-shaped plate 12 and threadedly connected to the U-shaped plate 12.

[0018] During disassembly, the operator pulls the two side plates 32 by hand, causing them to slide within the same side groove 31. This moves the two side limit blocks 23 simultaneously, preventing the operator from directly pressing the two side limit blocks 23, which is inconvenient for one person to operate alone, thus improving the convenience of the device. During use, the movement of the pull plate 32 causes the guide rail cover 4 on it to fold or unfold simultaneously. The guide rail cover 4 can cover the pull plate 32, preventing dust from entering the mounting groove 22 through the pull plate 32, which would cause blockage and make cleaning difficult. The operator can unscrew the bolts 6 on each plate 25 to remove the limiting fixation of the plate 25. This allows the plate 25 on the tensioning guide wheel body 13 that needs to be replaced to be removed and reused, reducing the operating cost of the device.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
