Description

Technical Field

[0001] This utility model relates to the field of twisting machine technology, and in particular to a yarn detection device for a twisting machine. Background Technology

[0002] A doubling machine is a yarn twisting device with the advantage of high efficiency. A yarn detection device is a device on a doubling machine used to detect whether the yarn breaks during transmission. Most existing yarn detection devices on doubling machines are photoelectric.

[0003] Photoelectric yarn detection devices primarily use photoelectric sensors fixed to one side of the yarn for monitoring. The sensors detect the presence of nearby yarn; when the yarn breaks or a loop of yarn is used up, the sensor detects no yarn, and the controller stops the twisting machine. Conversely, the sensor detects yarn when the yarn breaks. Photoelectric yarn detection devices are simple in structure, low in cost, and do not cause yarn jamming or twisting machine malfunctions.

[0004] However, when using photoelectric devices, lint in the workshop can easily drift to the detection end of the photoelectric sensor. When the yarn breaks or a loop of yarn is used up, the photoelectric sensor still mistakenly thinks that it has detected yarn. The controller cannot stop the twisting machine in time, and the photoelectric yarn detection device is not sensitive and its operation is unstable. Utility Model Content

[0005] The purpose of this invention is to provide a yarn detection device for a twisting machine, which aims to solve the problems of unresponsiveness and unstable operation of existing photoelectric yarn detection devices.

[0006] To achieve the above objectives, this utility model provides a yarn detection device for a twisting machine, including a connecting assembly, on which a connecting seat is rotatably mounted, and also includes an auxiliary assembly;

[0007] The auxiliary components include a first hollow tube, a first bearing housing, a second hollow tube, a bearing, a rear spacer, a retaining ring, a locking member, and a switching member. The first hollow tube is threadedly connected to the connecting seat, and the first bearing housing is threadedly connected to the first hollow tube. The second hollow tube is mounted on the detection wheel and the first bearing housing via the bearing. The outer ring of the bearing is limited by the retaining ring, and the inner ring is limited by the locking member. The rear spacer is used to limit the inner ring of the bearing on the rear side. The switching member is disposed on the body of the device.

[0008] The connecting assembly includes a second bearing housing and a sleeve. The second bearing housing is mounted on the body of the equipment via multiple sleeves. The sleeves are integrally formed with the second bearing housing.

[0009] The locking component includes a front spacer ring and a threaded ring. The front spacer ring is sleeved on the second hollow tube and abuts against the inner ring of the bearing. The threaded ring is threadedly installed on the second hollow tube and is arranged front and rear.

[0010] The switching component includes a pad and a limit switch. The pad is detachably connected to the body of the equipment, and the limit switch is mounted on the pad.

[0011] The yarn detection device of the twisting machine also includes a protective component, which includes a threaded cover and a rectangular plate. The threaded cover is threadedly connected to the second hollow tube and is arranged at the front and rear. The rectangular plate is integrally disposed on the threaded cover.

[0012] This utility model discloses a yarn detection device for a twisting machine. The device is fixed to the machine body via a connecting device, and a switch component is installed on the machine. When the detection wheel is in contact with the yarn, the first hollow tube is tilted. When the yarn breaks or runs out, the yarn tension disappears, and under the action of gravity, the detection wheel falls, and the first hollow tube presses against the switch component. This allows the controller of the twisting machine to receive a signal, and the twisting machine immediately stops. Compared with photoelectric devices, this application is more stable and is not affected by workshop lint, thus solving the problems of unresponsiveness and unstable operation of existing photoelectric yarn detection devices.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Example 1:

[0020] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of the yarn detection device of a doubling twister. Figure 2 This is a cross-sectional view of the detection wheel 108. This utility model provides a yarn detection device for a twisting machine: it includes a connecting assembly, a connecting seat 101, and an auxiliary assembly. The auxiliary assembly includes a first hollow tube 102, a first bearing seat 103, a second hollow tube 104, a bearing 105, a rear spacer ring 106, a retaining ring 107, a locking component, and a switching component. The connecting assembly includes a second bearing seat 109 and a sleeve 110. The locking component includes a front spacer ring 111 and a yarn ring 112. The switching component includes a pad 113 and a limit switch 114. The aforementioned solution solves the problems of unresponsiveness and unstable operation of existing photoelectric yarn detection devices. It is understood that the aforementioned solution can improve the working stability of the yarn detection device.

[0021] In this embodiment, a connecting seat 101 is rotatably mounted on the connecting assembly. The connecting seat 101 is used to rotate the first hollow tube 102. The first hollow tube 102 and the second hollow tube 104 are made of hollow aluminum tubes, and the detection wheel 108 is made of plastic. The above arrangement is to reduce the impact on the tension of the yarn.

[0022] The first hollow tube 102 is threadedly connected to the connecting seat 101, the first bearing seat 103 is threadedly connected to the first hollow tube 102, the second hollow tube 104 is mounted on the detection wheel 108 and the first bearing seat 103 via the bearing 105, the outer ring of the bearing 105 is limited by the snap ring 107, the inner ring is limited by the locking member, the rear spacer ring 106 is used to limit the inner ring of the rear bearing 105, and the switch member is disposed on the body of the device. The first hollow tube 102 has externally threaded ends on both sides for easy connection with the first bearing seat 103 and the connecting seat 101. The detection wheel 108 has stepped grooves on both sides for easy installation of the bearing 105. The outer ring of the bearing 105 is limited by the retaining ring 107. The bearing 105 has a structure with dust covers on both sides to reduce the entry of workshop lint and prevent jamming. One side of the rear spacer ring 106 abuts against the limiting end face of the second hollow tube 104, and the other side abuts against the inner ring of the rear bearing 105. The detection wheel 108 has a mounting groove for easy installation of the retaining ring 107. The retaining ring 107 is a hole retaining ring, which is used to limit the inner ring of the bearing 105 after installation to prevent the bearing 105 from moving during the transmission engagement of the second hollow tube 104 and the detection wheel 108.

[0023] Secondly, the second bearing housing 109 is mounted on the body of the equipment via a plurality of sleeves 110; the sleeves 110 are integrally formed with the second bearing housing 109. A plurality of sleeves 110 are evenly spaced in a ring on the second bearing housing 109, which facilitates fixing it to the body of the equipment by means of positioning pins and bolts. The bearing housing is provided inside, which facilitates the installation of the rotating shaft of the connecting seat 101 by means of a rotating bearing.

[0024] Then, the front spacer 111 is sleeved on the second hollow tube 104 and abuts against the inner ring of the bearing 105; the threaded ring 112 is threadedly installed on the second hollow tube 104 and is arranged front and rear. The front spacer 111 is sleeved on the second hollow tube 104 and grounded to the inner ring of the bearing 105 on the front side. The threaded ring 112 is used to limit the front spacer 111 and is directly installed on the stepped external thread end of the second hollow tube 104.

[0025] Finally, the pad 113 is detached and connected to the body of the equipment; the limit switch 114 is installed on the pad 113. The pad 113 is fixed by bolts and locating pins, and the limit switch 114, model LX19-001, is fixed by bolts.

[0026] When using this utility model to solve the problems of unresponsiveness and unstable operation of existing photoelectric yarn detection devices, the device is fixed to the machine body of the equipment through the connecting device, and the switching component is set on the equipment. When the detection wheel 108 is attached to the yarn, the first hollow tube 102 is in an inclined state. When the yarn breaks or runs out, the yarn tension disappears, and the detection wheel 108 will fall under the action of gravity. At this time, the first hollow tube 102 will move and press against the limit switch 114, so that the controller of the twisting machine will receive a signal and the twisting machine will stop immediately. Compared with the photoelectric device, this application is more stable and is not affected by workshop lint, thus solving the problems of unresponsiveness and unstable operation of existing photoelectric yarn detection devices.

[0027] Example 2:

[0028] like Figure 3 As shown, where Figure 3 This is a schematic diagram of the overall structure of the yarn detection device for a twisting machine. Based on the first embodiment, this utility model provides a yarn detection device for a twisting machine. The yarn detection device for a twisting machine also includes a protective component, which includes a threaded cap 201 and a rectangular piece 202.

[0029] The threaded cap 201 is threadedly connected to the second hollow tube 104 and is positioned at both ends; the rectangular piece 202 is integrally formed on the threaded cap 201. The inner walls of the second hollow tube 104 are provided with stepped threaded cavities for direct installation of the threaded cap 201. The rectangular piece 202 is integrally formed with the threaded cap 201.

[0030] In this embodiment, the threaded cap 201 and the rectangular piece 202 are both made of plastic. After the threaded cap 201 is installed, it seals both ends of the second hollow tube 104, reducing the entry of workshop lint into the interior and preventing the accumulation of impurities inside the second hollow tube 104 after a long period of time.

[0031] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
