The inclination adjustment device 4 includes a connecting rod 41, an inclination power device 42, a transmission device 43 and a limit device 44; , make them constitute the four-bar linkage (the swinging push rod 35 of the yarn detection rod, the sensor swing push rod 232 are the connecting rods of the four-bar linkage, the connecting rod 41 is the connecting rod of the four-bar linkage, and the mobile dolly is a four-bar linkage frame of the mechanism); transmission device 43 is to remove the quincunx coupling of buffer block, and inclination power device 42 is a stepper motor or DC geared motor, and the rotation of inclination power device 42 is transmitted to the four-bar linkage by transmission device 43 At the fixed shaft (in this embodiment, the inclination power device 42 is installed on the spindle sensor assembly mounting plate, and its power is transmitted to the fixed end of the spindle sensor mounting plate rotating shaft 231, but it does not exclude transmission to the yarn feeler rod mounting plate rotating shaft 31 fixed end), the forward and reverse rotation of the inclination power device 42 controls the position of the four-bar linkage mechanism, thereby changing the positions of the spindle sensor 21 and the yarn detection rod 37, and the limit device 44 is installed on the spindle sensor assembly. 2 bolts on the plate 13, the spindle sensor 21 in the swing process, the spindle sensor mounting plate 22 contacts the screw rod end of the limit device, and limits the limit position of the spindle sensor 21 and the yarn detection rod 37 swings (also can simultaneously The limiting device is installed on the spinning probe rod assembly mounting plate 12, so that it limits the swing range of the yarn probe rod swing plate 33). When the spindle sensor and the yarn detection rod are in their two limit positions, the center of gravity of all parts that swing together with the spindle sensor and the yarn detection rod is the same as the rotation axis of the spindle sensor installation plate rotating shaft 231 and the yarn detection rod installation plate rotation axis The positional relationship between the rotary axes of 31 can ensure that the yarn detecting rod and the spindle sensor stay at their two extreme positions. Driven by the device, in order to facilitate control, the positions of the input side and the output side of the transmission device 43 are not in one-to-one correspondence, and a certain (larger than the circumferential gap of the general coupling) rotation gap should be reserved between them, that is, the inclination power device When the rotating shaft of 42 is not rotating, the rotating shaft of the spindle sensor mounting plate or the rotating shaft of the yarn detecting rod mounting plate can rotate at a certain (for example, not less than 5°) angle. For this reason, the buffer block of the plum blossom coupling is removed as the transmission device 43 , but does not exclude the use of flexible shafts and elastic couplings as transmission devices.

When the avoidance-type spinning broken end detection device is used in the spinning frame, it is placed on the track 7 of the spinning frame. The spinning frame track includes an upper guide rail 71 and a lower guide rail 72. Since the upper guide rail 71 of different types of spinning frames has different installation methods, as shown in Fig. 1 and Fig. 2, the bracket 711 of the upper guide rail 71 of the spinning frame is installed on the lower part of the channel steel 73 of the spinning frame. The upper part of 71 swings close to the spindle, but the bracket of the upper guide rail of the spinning frame of some models is installed on the upper part of the channel steel 73 of the spinning frame (as shown in Figure 3). In this case, in order to prevent the spindle sensor from interfering with the guide rail bracket, The ingot sensor can only swing close to the ingot at the bottom of the upper guide rail.

Since the ingot sensor mounting plate in this embodiment can not interfere with the mounting plate installing the driving device during the swing process, only one column of the mobile trolley can be used, and the supporting wheel 15, the driving wheel 16 and the driving device 17 can be Be installed on the ingot sensor assembly mounting plate 13, at this moment, the ingot sensor assembly mounting plate 13 is as the mounting plate of driving device and driving wheel, and in this case, only one is installed in the righting wheel.

The collector contacts the conductive trolley line installed on the spinning frame during the movement of the moving trolley to take power, and the lead wire of the collector is connected to Terminals of the battery.

In order to quickly reset the yarn detection rod and replace the movable stopper to prevent the continuous swing of the blocking rod, a magnetic steel 391 facing the movable stopper and the blocking rod is installed on the yarn detection rod swing plate close to the yarn detection rod installation plate. The steel can attract the blocking rod, and the size of the magnetic steel and the distance between the magnetic steel and the end of the blocking rod can be adjusted to prevent the yarn detecting rod from swinging too much, and prevent the yarn detecting rod from interrupting the spun yarn.

There are two standard guide rails on the spinning frame without collective doffing device. The guide rail with the same height as the spindle is the upper guide rail, and the round tube or flat tube guide rail closer to the ground is used as the lower guide rail. If the standard guide rail is The length is only the length of the car surface, and one side guide rail is extended to the end of the car head, and the other side guide rail is extended to the end of the car rear, so that the avoidance type spun yarn breakage detection device can be moved close to the end of the car front or car rear to prevent its Affect the use of doffing trolley for doffing, suspend the support wheel 15 and driving wheel 16 of the avoidance type spun end break detection device on the upper guide rail, and put the centering wheel against the side of the lower guide rail to detect the avoidance type spun end breakage.

The avoidance-type spun yarn breakage detection device moves on the guide rail until its control device detects the head mark or the tail mark and reverses the movement. After the reverse movement, the stopper electromagnet is energized and pulls down the stopper to prevent the The moving yarn detection rod bends the movable block or breaks the spun yarn because the movable block hinders the rotation of the blocking rod. Combining the detection of the front and rear of the car with the detection of the spindle, the position number of the detected spindle position can also be judged, that is, the active The first spindle position detected after the trolley changes direction from the front is No. 1, and so on.
