Description

Technical Field

[0001] The utility model relates to the technical field of spinning equipment, and particularly relates to a signal conversion device for the secondary speed increase of TMT winding and spinning. Background Technique

[0002] Due to technical transformation and equipment reuse in this workshop, when introducing TMT winding equipment, the existing spinning equipment was not updated synchronously. In subsequent energy conservation, consumption reduction, cost reduction, and efficiency improvement projects, since the speed increase signals of the TMT winding control cabinet are all pulse signals, while the existing spinning equipment uses electric signals or switch signals, which do not match each other, the secondary speed increase pulse signal sent by the TMT winding control cabinet cannot be recognized by the frequency conversion of the spinning metering pump, resulting in difficulties in promoting the secondary speed increase of the TMT equipment. Although replacing the frequency conversion of the spinning metering pump with a frequency converter that can recognize pulse signals can solve the above problems, this method has a large investment and a long transformation period, which goes against the original intention of energy conservation, consumption reduction, cost reduction, and efficiency improvement. Therefore, to solve this problem, a signal conversion device needs to be added to achieve the intercommunication between the TMT speed increase signal and the secondary speed increase signal of the spinning metering pump frequency conversion, and finally complete the spinning secondary speed increase transformation project. Summary of the Invention

[0003] In order to solve certain or some technical problems existing in the prior art, the purpose of this application is to provide a signal conversion device for the secondary speed increase of TMT winding and spinning, which can solve the problem that the secondary speed increase pulse signal sent by the TMT winding control cabinet cannot trigger the secondary speed increase mode of the spinning metering pump frequency conversion because it cannot be recognized by the spinning metering pump frequency conversion, and has a low transformation cost and a short cycle.

[0004] To solve the above existing technical problems, the following technical solutions are adopted in this application:

[0005] A signal conversion device for the secondary speed increase of TMT winding and spinning includes a frequency conversion of a spinning metering pump and a TMT winding control cabinet. A signal conversion relay module is arranged between the frequency conversion of the spinning metering pump and the TMT winding control cabinet. The signal conversion relay module is arranged in parallel with the output end of the winding secondary speed increase pulse signal of the PLC in the TMT winding control cabinet through a signal line. The output end of the signal conversion relay module is connected in series with the frequency conversion of the spinning metering pump through a signal line. The winding secondary speed increase pulse signal of the PLC in the TMT winding control cabinet is converted into an electric signal or a switch signal that can be recognized by the frequency conversion of the spinning metering pump through the signal conversion relay module.

[0006] Preferably, a track is arranged in the TMT winding control cabinet, and the signal conversion relay module is arranged on the track.

[0007] Preferably, the track includes a U-shaped chute and two clamping blocks arranged at the opening end of the chute and turned inward. A clamping groove matching the clamping blocks is provided at the rear end of the signal conversion relay module, and the bottom of the signal conversion relay module is slidably connected to the chute through the clamping blocks.

[0008] Preferably, the track is horizontally arranged on the side of the TMT winding control cabinet. The inner end of the track is blocked by the TMT winding control cabinet, and a plug is provided at the outer end of the track.

[0009] Preferably, a signal shielding layer is wrapped outside the signal line for transmitting electrical signals.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] After the whole transformation is completed, it can effectively solve the problem that the secondary speed-up pulse signal emitted by the existing TMT winding control cabinet cannot be recognized by the frequency conversion of the spinning metering pump, resulting in the inability to trigger the secondary speed-up mode of the spinning metering pump frequency conversion. The whole transformation only needs to add a signal conversion relay module, and through this component for signal form conversion, the goal can be achieved. The transformation cost is low. At the same time, there is no need for large-area shutdown. The installation of the module and the signal line can be realized. As long as the frequency conversion of the metering pump is connected to the signal line during unit shutdown, the transformation can be completed. The transformation cost is low and the transformation period is short. Description of the Drawings

[0018] As Figure 1 shown, a TMT winding and spinning secondary speed increase signal conversion device includes a spinning metering pump frequency converter 3 and a TMT winding control cabinet 1. A signal conversion relay module 8 is provided between the spinning metering pump frequency converter 3 and the TMT winding control cabinet 1. The signal conversion relay module 8 is connected in parallel with the winding secondary speed increase pulse signal output end of the PLC 2 in the TMT winding control cabinet 1 through a signal line 4. The output end of the signal conversion relay module 8 is connected in series with the spinning metering pump frequency converter 3 through the signal line 4. The winding secondary speed increase pulse signal of the PLC 2 in the TMT winding control cabinet 1 is converted into an electrical signal or a switch signal that can be recognized by the spinning metering pump frequency converter 3 through the signal conversion relay module 8.

[0019] During actual use, first, install the signal conversion relay module 8 in the blank space inside the TMT winding control cabinet 1. Then, parallelly connect a 0.5-mm signal line 4 from the output terminal of the winding second speed-up pulse signal of the PLC 2 inside the TMT winding control cabinet 1 to the signal conversion relay module 8. Connect the electrical signal or switch signal that can be recognized by the spinning metering pump frequency converter 3 after being converted by the signal conversion relay module 8 from the output terminal on the signal conversion relay module 8 to the spinning metering pump frequency converter 3 through the signal line 4. Set the parameters for the second speed-up of the metering pump frequency conversion, and the transformation of the TMT winding to spinning second speed-up signal device is completed. After the entire transformation is completed, it can effectively solve the problem that the existing TMT winding control cabinet 1 emits a second speed-up pulse signal that cannot be recognized by the spinning metering pump frequency converter 3, resulting in the inability to trigger the second speed-up mode of the spinning metering pump frequency converter 3. The entire transformation only requires adding the signal conversion relay module 8 and performing signal form conversion through this component to achieve the goal. The transformation cost is low. At the same time, there is no need for large-scale shutdown. The installation of the module and the signal line 4 can be achieved. As long as the metering pump frequency conversion is connected to the signal line 4 during unit shutdown, the transformation can be completed. The transformation cost is low and the transformation period is short.

[0020] Further improvement is made as Figure 2 shown, a track 7 is provided inside the TMT winding control cabinet 1, and the signal conversion relay module 8 is arranged on the track 7.

[0021] Installing the signal conversion relay module 8 through the track 7 is more flexible during installation, and the spatial position adjustment is more convenient. During assembly, it can be assembled in an area with sufficient space and then slid to the required position. The installation flexibility is higher.

[0022] Even further improvement is made as follows: The track 7 includes a U-shaped chute 72 and two clamping blocks 71 arranged at the opening end of the chute 72 and turned inward. A clamping groove 6 matching the clamping blocks 71 is provided at the rear end of the signal conversion relay module 8, and the bottom of the signal conversion relay module 8 is slidably connected to the inside of the chute 72 through the clamping blocks 71.

[0023] The track 7 is composed of a U-shaped chute 72 and two inwardly turned clamping blocks 71. The overall structure is simple and the procurement cost is low. Moreover, when connecting with the signal conversion relay module 8, the bottom of the signal conversion relay module 8 aligns the clamping groove 6 with the clamping blocks 71 and pushes inward, and the two can be assembled. After assembly, the rear end of the signal conversion relay module 8 is embedded in the chute 72, which can not only play a role of relative limit but also play a role of a slider to make the sliding smoother, and the stability after installation is better.

[0024] Further improvement is that the track 7 is horizontally arranged on the side of the TMT winding control cabinet 1, the inner end of the track 7 is blocked by the TMT winding control cabinet 1, and a plug 9 is provided at the outer end of the track 7.

[0025] The track 7 is horizontally installed on the side of the TMT winding control cabinet 1. When installing the track 7, disassembly and fixing can be achieved only by bolts, which is more convenient during assembly. Moreover, the inner end of the track 7 is blocked by the inner side of the TMT winding control cabinet 1, which can prevent the signal conversion relay module 8 from falling out during the inward sliding process. And a plug 9 is provided at the outer end of the track 7. Since the signal conversion relay module 8 has no locking structure, when the TMT winding control cabinet 1 is moved or needs to be overturned during maintenance, the signal conversion relay module 8 will slide outwards along the track 7, resulting in a falling-off phenomenon. After installing the plug 9, it can prevent the signal conversion relay module 8 from directly sliding off due to inclination or accidental touch during assembly or the movement of the TMT winding control cabinet 1.

[0026] Further improvement is that a signal shielding layer 5 is wrapped outside the signal line 4 for transmitting electrical signals.

[0027] Since the distance between the TMT winding control cabinet 1 and the spinning metering pump frequency converter 3 is relatively far, the transmission of electrical signals is seriously interfered. There are problems with signal confusion when using conventional signal lines 4. Therefore, special shielded signal lines 4 need to be used to solve this hidden danger. However, the special shielded signal lines 4 themselves are relatively expensive, resulting in high costs, and the butt-joint of multiple lines is also prone to form a messy line phenomenon. Therefore, in order to reduce costs and solve the problem of messy lines at the same time, a signal shielding layer 5 is wrapped outside multiple signal lines 4 in the same circuit with signal shielding tape. Through the setting of the signal shielding layer 5, the above problems are effectively solved.

[0028] The above embodiments are only the preferred embodiments of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by those skilled in the art based on the present application belong to the scope of protection required by the present application.
