Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and in particular to an automatic synchronization device for a combing machine and the combing machine itself. Background Technology

[0002] In the textile industry, combing machines are key production equipment, used to finely comb cotton, linen, and other fibers to improve fiber quality and uniformity. However, traditional combing machines have some shortcomings in operation. For example, when the main motor stops running, i.e., when the combing machine is notified to start, the compressed air is still in maximum release mode, requiring manual closing of the compressed air valve. However, the valve cannot be completely closed; a slight opening is needed to allow a small flow of compressed air to continuously blow out, thus keeping the combing machine's working surface clean. This not only increases the labor intensity of workers but also affects production efficiency. Furthermore, existing production facilities need improvement in energy conservation and consumption reduction, resulting in significant energy waste and cost expenditures.

[0003] To address the aforementioned issues, this project aims to develop an automatic synchronous operation device for a combing machine. This device synchronizes the opening and closing of pneumatic valves with the start and stop of the main motor, thereby avoiding the continuous release of compressed air during machine shutdown or the need for manual closure of compressed air valves. By improving some production facilities, the project increases production capacity, reduces labor intensity, decreases the number of workers on the production line, lowers processing costs, and improves production efficiency. Utility Model Content

[0004] In view of this, in order to solve the problem of needing to manually close or adjust the compressed air valve, the present invention provides an automatic synchronization device for a combing machine and a combing machine.

[0005] The present invention provides an automatic synchronization device for a combing machine and a combing machine, wherein the automatic synchronization device for the combing machine includes:

[0006] The system includes a motor M, a main control relay, an intermediate relay, a normally closed solenoid valve YV1, and a normally open solenoid valve YV2. One end of the motor M's contact is electrically connected to the positive terminal of the power supply via a switch S1, and the other end is electrically connected to the negative terminal of the power supply. One end of the coil KA1 of the main control relay is electrically connected to the switch S1. One end of the normally open contact KA2 of the main control relay is electrically connected to the positive terminal of the power supply, and the other end is electrically connected to one end of the coil KM1 of the intermediate relay. The other end of the coil KM1 of the intermediate relay is electrically connected to the negative terminal of the power supply. One end of the normally open contact KM2 of the intermediate relay is electrically connected to the positive terminal of the power supply via the normally closed solenoid valve YV1, and the other end is electrically connected to the negative terminal of the power supply. One end of the normally closed contact KM3 of the intermediate relay is electrically connected to the positive terminal of the power supply via the normally open solenoid valve YV2, and the other end is electrically connected to the negative terminal of the power supply.

[0007] Furthermore, the normally closed solenoid valve YV1 and the normally open solenoid valve YV2 are respectively installed on the ventilation duct of the blow-out air outlet of the combing machine.

[0008] Furthermore, the flow rate of the normally closed solenoid valve YV1 is greater than that of the normally open solenoid valve YV2.

[0009] Furthermore, one end of the normally closed contact KM3 of the intermediate relay is electrically connected to one end of the normally open solenoid valve YV2 via switch S2, and the other end of the normally open solenoid valve YV2 is electrically connected to the positive terminal of the power supply.

[0010] Furthermore, an indicator light L2 is provided for the electrical connection between the normally open solenoid valve YV2 and the positive terminal of the power supply.

[0011] Furthermore, an indicator light L1 is provided for the electrical connection between the normally closed solenoid valve YV1 and the positive terminal of the power supply.

[0012] Furthermore, the motor M is the main power motor for the combing machine during operation.

[0013] Another type of combing machine includes a combing machine body and the aforementioned automatic synchronization device for the combing machine, wherein the automatic synchronization device is disposed on the combing machine body so that when the motor M is working, the normally closed solenoid valve YV1 is working and the normally open solenoid valve YV2 is not working.

[0014] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows:

[0015] First, the opening and closing of normally closed solenoid valve YV1 and normally open solenoid valve YV2 can be controlled by starting and stopping motor M, thereby controlling whether the compressed air blown out meets the maximum flow rate required for work or the small flow rate required for cleaning.

[0016] Secondly, it reduces labor costs and solves the problem of recruitment difficulties: The introduction of automated equipment has significantly reduced the labor demand on the production line. This not only helps to solve the current widespread problem of recruitment difficulties in the textile industry, but also saves labor costs for enterprises. Attached Figure Description

[0018] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0019] Please refer to Figure 1 An embodiment of this utility model provides an automatic synchronization device for a combing machine, including a motor M, a main control relay, an intermediate relay, a normally closed solenoid valve YV1, and a normally open solenoid valve YV2.

[0020] In this embodiment, normally closed solenoid valve YV1 and normally open solenoid valve YV2 are respectively installed on the ventilation duct of the combing machine's blow-out air outlet. The amount of airflow blown out is controlled according to the opening and closing status of different solenoid valves to meet the needs of different working conditions.

[0021] In this embodiment, motor M is the main working motor of the combing machine. When motor M starts, the combing machine starts to work and requires compressed air of the maximum flow rate to be blown out from the external blowing equipment. It should be noted that the external blowing equipment is an existing device, which mainly works in conjunction with the combing machine. The automatic synchronization device for the combing machine in this embodiment is mainly used to control whether the flow rate of the compressed air blown out meets the working requirements.

[0022] In this embodiment, the motor M is electrically connected to the positive and negative terminals of the power supply, thereby providing energy for starting the motor M. In this embodiment, the end of the motor M connected to the positive terminal of the power supply is connected to the positive terminal of the power supply through switch S1, which is the start / stop switch of the motor M.

[0023] The main control relay includes a coil KA1 and a normally open contact KA2. One end of the coil KA1 of the main control relay is electrically connected to the switch S1. One end of the normally open contact KA2 of the main control relay is electrically connected to the positive terminal of the power supply, and the other end is electrically connected to the negative terminal of the power supply. When the switch S1 is closed, the motor M is energized and starts to work. At the same time, the coil KA1 of the main control relay is energized, which drives the normally open contact KA2 to close.

[0024] The intermediate relay includes a coil KM1, a normally open contact KM2, and a normally closed contact KM3. One end of the intermediate relay coil KM1 is electrically connected to one end of the normally open contact KA2 of the main control relay, and the other end is electrically connected to the negative terminal of the power supply. One end of the intermediate relay normally open contact KM2 is electrically connected to the negative terminal of the power supply, and the other end is electrically connected to one end of the normally closed solenoid valve YV1. The other end of the normally closed solenoid valve YV1 is electrically connected to the positive terminal of the power supply through an indicator light L1. When the coil KA1 of the main control relay is energized, it drives the normally open contact KA2 to close, and the coil KM1 of the intermediate relay is energized, thereby driving the normally open contact KM2 of the intermediate relay to close. As a result, the normally closed solenoid valve YV1 is energized and opened, and the indicator light L1 is energized and lit. Thus, the flow rate purged by the external purging equipment is the opening degree of the normally closed solenoid valve YV1.

[0025] It should be noted that the normally closed solenoid valve YV1 is closed when it is not energized, and compressed air from external purging equipment cannot be purged out through the normally closed solenoid valve YV1. Compressed air can only be purged out through the normally closed solenoid valve YV1 when it is energized and opened.

[0026] In this embodiment, the flow rate of the normally closed solenoid valve YV1 is greater than that of the normally open solenoid valve YV2, and the flow rate of the normally closed solenoid valve YV1 matches the compressed air flow rate required by the combing machine during normal operation.

[0027] One end of the normally closed contact KM3 of the intermediate relay is electrically connected to the negative terminal of the power supply, and the other end is electrically connected to one end of the normally open solenoid valve YV2 through switch S2. The other end of the normally open solenoid valve YV2 is electrically connected to the indicator light L2 and is electrically connected to the positive terminal of the power supply through the indicator light L2. When the coil KA1 of the main control relay is energized, it drives the normally open contact KA2 to close, and the coil KM1 of the intermediate relay is energized, thereby driving the normally closed contact KM3 of the intermediate relay to open. As a result, the normally open solenoid valve YV2 is de-energized and closes, and the indicator light L2 is de-energized and goes out. Thus, the compressed air blown out by the external purging equipment cannot be blown out through the normally open solenoid valve YV2.

[0028] It should be noted that the normally open solenoid valve YV2 is open when not de-energized. When the motor M is not working, the coil KM1 of the intermediate relay is not energized, and its normally closed contact KM3 is closed. In this case, simply pressing the switch S2 will keep the normally open solenoid valve YV2 energized, thus ensuring that the normally open solenoid valve YV2 remains open, allowing compressed air from the external purging equipment to be purged through the normally open solenoid valve YV2. It should also be noted that the flow rate of the normally open solenoid valve YV2 is matched with the flow rate of compressed air required to keep the combing machine clean when it is not working.

[0029] This embodiment also includes a combing machine, which includes a combing machine body and the above-mentioned automatic synchronization device for the combing machine, wherein the automatic synchronization device is disposed on the combing machine body so that when the motor M is working, the normally closed solenoid valve YV1 is working and the normally open solenoid valve YV2 is not working.

[0030] The working principle of this embodiment is as follows: When the combing machine is working normally, that is, the motor M needs to be energized, so the switch S1 is closed, the motor M works, and at the same time, the coil KA1 of the main control relay is energized, its normally open contact KA2 is closed, which in turn energizes the coil KM1 of the intermediate relay. As a result, the normally open contact KM2 of the intermediate relay is energized and closed, and the normally closed contact KM3 is energized and opened. When the normally open contact KM2 is closed, the normally closed solenoid valve YV1 is energized and opened, and the compressed air blown out by the external purging equipment can be blown out through the normally closed solenoid valve YV1, thereby meeting the compressed air flow required for the normal operation of the combing machine. At the same time, the illumination of the indicator light L1 indicates that the compressed air is passing through the normally closed solenoid valve YV1. At the same time, when the normally closed contact KM3 is energized and opened, the normally open solenoid valve YV2 is de-energized and closed, and the compressed air cannot be blown out through the normally open solenoid valve YV2. The extinguishing of the indicator light L2 indicates that the compressed air is not passing through the normally open solenoid valve YV2.

[0031] When the combing machine is not working, a small amount of compressed air is needed for cleaning and purging. Simply turning off switch S1 will stop the motor M, thus de-energizing the coil KA1 of the main control relay, causing its normally open contact KA2 to open. The coil KM1 of the intermediate relay will also be de-energized, causing its normally open contact KM2 to open and its normally closed contact KM3 to close. At this point, simply turning off switch S2 will energize the normally open solenoid valve YV2 and keep it open, allowing compressed air to be purged through the normally open solenoid valve YV2, thus meeting the compressed air flow required for cleaning and purging. At the same time, the indicator light L2 will illuminate to indicate that the compressed air is being purged through the normally open solenoid valve YV2.
