[0002] Guide shafts are widely used in various industrial manufacturing production lines. In the transmission process of the equipment, the use of guide shafts plays the role of positioning and directional rotation or linkage. When guide shafts are used in the textile industry, they are often used in the winding mechanism for internal transmission or positioning of the winding. However, the use of internal guide shafts in the winding mechanism can only connect and transmit force, with poor functionality. It cannot improve the winding efficiency or provide other practical functions such as prompts for operations.

[0003] The existing guide shaft used in the winding mechanism can only be used as a connecting member and cannot prompt the removal or directional movement. For example, a guide shaft positioning device disclosed in publication number CN214080327U includes a support seat and a guide shaft body, the top of the support seat is provided with a first slide groove, the first slide groove is movably connected to a first slider and a sliding block, the bottom inner wall of the first slide groove is fixedly connected to a motor, one end of the motor output shaft is fixedly connected to a first screw, one end of the first screw passes through the first slider and the sliding block, the first slider is threadedly connected to the first screw, the sliding block is gap-connected to one side of the first screw, the top of the first slider and the sliding block are respectively fixedly connected to an adjustment platform, the top of the adjustment platform is provided with a second slide groove, the second slide groove is movably connected to a second slider, and one side of the adjustment platform is provided with a plug hole. The utility model can accurately position the processing of the guide shaft body, improve the processing efficiency of the guide shaft, and can also well fix the guide shaft to facilitate subsequent processing. However, when this guide shaft is used in the winding mechanism, it cannot achieve the effect of quantitative winding and quantitative removal.

[0004] Therefore, it is necessary to invent a guide mechanism for a guide shaft to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a guide mechanism for a guide shaft, so as to solve the problems in the technology of low efficiency of wire winding and reeling, uneven winding surface and inability to quantify.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a guiding mechanism of a guide shaft, comprising a winding head, a combing protrusion, a positioning hole, a guide shaft one, a guide shaft two and a threaded connecting shaft, the top of the winding head is provided with a plurality of combing protrusions with a right-angled triangle cross-section, and the longest side of the right-angled triangle is wavy, the combing protrusion is in direct contact with the silk thread, and a positioning hole is provided in the combing protrusion, the side of the winding head is provided with a curved guide groove, and a tray is provided below the guide groove, the bottom of the tray is sleeved on the guide shaft one and is slidably connected to the guide shaft one, a plurality of slide grooves are provided in the guide shaft one, and a spring is installed in the slide groove, the bottom of the guide shaft one extends into the mounting hole in the guide shaft two through an insertion rod, and the bottom of the mounting hole is fixedly connected to the threaded connecting shaft.

[0007] Preferably, the top of the spring is fixedly connected to the limiting member 1 and the limiting member 2, the limiting member 1 is in close contact with the bottom of the tray, the limiting member 2 extends into the bottom of the positioning hole, and the diameter of the limiting member 2 is adapted to the width of the slot.

[0008] Preferably, an inner sleeve is provided inside the guide shaft, a plurality of slots are provided on the top of the inner sleeve, and the positions of the plurality of slots correspond to the positions of the plurality of slide grooves.

[0009] Preferably, an infrared sensor is installed in the positioning hole, and the distance to the second limiting member is determined by the infrared rays meeting the second limiting member.

[0010] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0011] 1. The utility model uses the special wavy combing protrusions on the winding head to evenly wind the silk thread thereon, so that the silk thread is wound evenly and quantitatively. When a fixed amount of silk thread is wound, the infrared sensor in the positioning hole can detect whether the distance between the infrared ray and the second limiter reaches a preset value, and then emit a sound signal to notify the removal. The silk thread roller that has been wound to the predetermined amount can be removed, making the winding and removal process more intelligent and the silk thread winding more uniform.

[0012] 2. Through the contact between the tray of the winding head and the limiter, as well as the transmission of force, when the tray is squeezed by the increasing amount of wound silk thread, it will be displaced, squeezing and pushing the spring and the inner sleeve downward, so that the entire guide shaft and the threaded connection shaft move downward. Then, the movement of the guide shaft and the threaded connection shaft into position can be used to intuitively judge whether to take the piece. The piece can be taken in two ways: sound signal notification and intuitive judgment of mechanical movement, thereby improving the efficiency of silk thread winding.

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] The utility model provides Figure 1-Figure 3 The guide mechanism of a guide shaft shown in the figure includes a winding head 1, a combing protrusion 101, a positioning hole 102, a guide shaft 1 2, a guide shaft 2 3 and a threaded connecting shaft 4. The top of the winding head 1 is provided with a plurality of combing protrusions 101 with a right triangle cross section, and the longest side of the right triangle is wavy. The combing protrusion 101 is in direct contact with the silk thread. A positioning hole 102 is provided in the combing protrusion 101. A curved dredging groove 103 is provided on the side of the winding head 1. A tray 104 is provided below the dredging groove 103. The bottom of the tray 104 is sleeved on the guide shaft 104 and is slidably connected to the guide shaft 104. A plurality of slide grooves 201 are provided in the guide shaft 104. A spring 202 is installed in the slide groove 201. The bottom of the guide shaft 104 extends into the mounting hole 301 in the guide shaft 203 through the insertion rod 208. The bottom of the mounting hole 301 is fixedly connected with the threaded connecting shaft 4. The top of the spring 202 is fixedly connected to the limiting member 103 and the limiting member 206. The limiting member 103 is tightly attached to the bottom of the tray 104. The limiting member 206 extends into the bottom of the positioning hole 102, and the diameter of the limiting member 206 is adapted to the width of the card slot 205.

[0023] The entire winding head 1 is used to wind the silk thread. When the silk thread is wound to a certain amount, the infrared sensor will send a sound signal to notify the removal of the thread, or the guide shaft 2 3 and the threaded connecting shaft 4 will be moved into place to observe whether the thread is removed.

[0024] An inner sleeve 204 is provided inside the guide shaft 2, and a plurality of slots 205 are provided on the top of the inner sleeve 204. The positions of the plurality of slots 205 correspond to the positions of the plurality of slide grooves 201. An infrared sensor is installed in the positioning hole 102, and the distance of the limiter 206 is judged by the infrared rays meeting the limiter 206. The inner sleeve 204 is threadedly connected to the threaded inner shaft 207, and the height of the inner sleeve 204 is less than the height of the guide shaft 2. The threaded inner shaft 207 is fixedly connected to the insertion rod 208, and the length of the insertion rod 208 is equal to the length of the guide shaft 2 3.

[0025] The slide groove 201 on the guide shaft 1 2 is used to link the movement of the tray 104, transferring force to the guide shaft 2 3 and the threaded connecting shaft 4, so that the rotation of the threaded connecting shaft 4 moves to the external receiving winding mechanism. A series of force guidance can make the winding module more efficient and intelligent.

[0026] The guiding grooves 103 and the combing protrusions 101 are arranged alternately, and the extension line of the guiding grooves 103 is in the middle of two adjacent combing protrusions 101 .

[0027] The function of the guiding groove 103 is to facilitate the guidance of the silk thread when it is wound, so that the silk thread is continuously wound downwardly, and the wound silk thread roll is more uniform and beautiful.

[0028] Working principle of this utility model:

[0029] Refer to the instruction manual Figure 1-Figure 3 When using the present invention, the combing protrusions 101 on the winding head 1 first contact the silk thread to be processed. Due to the special wave shape of the combing protrusions 101, the silk thread can be evenly wound and is not easy to fall off (the wave shape design increases the contact area with the silk thread), and the positioning hole 102 on the top will always leak out and will not block infrared rays.

[0030] Refer to the instruction manual Figure 3-Figure 6 When using the present invention, as the silk thread is continuously wound and more and more silk thread is wound, the mass on the winding head 1 becomes larger and larger, and begins to squeeze the tray 104 downward along the axial direction. The squeezing force is transmitted to the limiter 1 203, squeezing the spring 202 and the limiter 2 206 (the position movement distance of the limiter 206 will be collected by the infrared sensor. When the distance reaches the preset maximum value, an acoustic signal is issued, and the item can be removed), pushing the inner sleeve 204 originally clamped in the slot 205 downward;

[0031] The downward push of the inner sleeve 204 will drive the rotation of the threaded inner shaft 207, and the insertion rod 208 will rotate downward to push the insertion rod 208 downward, so that the entire threaded connecting shaft 4 is pushed downward, and the force is transmitted to the winding mechanism connected to the threaded connecting shaft 4. According to the maximum distance signal of the infrared sensor, it can be judged that the winding quantity on the winding head 1 has been reached (the limit member 206 moves downward to the farthest distance), and the threaded connecting shaft 4 can also be moved downward to the external winding mechanism to determine that the silk thread has been wound enough and can be removed.
