Detailed Description
The technical solution of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, an automatic roving stopping and re-feeding device for a spinning frame according to an embodiment of the present invention includes a driver 2 including a moving member 201, wherein the driver 2 drives the moving member 201 to move back and forth. The moving element 201 moves to realize roving stopping and re-feeding.
In this embodiment, the driver 2 is used to drive the moving member 201 to move back and forth, so as to stop and re-feed the roving. For example, the driver 2 drives the moving element 201 to move forward, so as to realize roving stop feeding; the driver 2 drives the moving element 201 to move backwards, and roving refeeding is achieved. This embodiment automatically realizes roving stop-feed and re-feed by driving the moving member 201 by the driver 2. Compared with manual feeding stopping and re-feeding in the prior art, the automatic feeding stopping and re-feeding device improves the working efficiency and achieves automation. This embodiment achieves automatic stopping and refeeding.
The driver 2 has various configurations, and the following configuration is preferable in the present embodiment.
The first structure is as follows: as shown in fig. 1, the driver 2 is a cylinder, and the moving member 201 is a piston rod in the cylinder.
When the yarn shoveling device works, the piston rod is connected with the yarn shoveling rod, and the piston rod drives the yarn shoveling rod to move. When the air cylinder works, the piston rod is driven to move in a reciprocating mode, and then the yarn shoveling rod is driven to move in a reciprocating mode. Specifically, the driving connector and the yarn shoveling rod move forwards or backwards, the notch ring yarn shoveling device which is sleeved on the rear roller in an empty way is driven to rotate for a phase, and the yarn shoveling device is made to rotate to enter or exit the jaw of the rear roller, so that the feeding stopping and re-feeding are realized.
During installation, the shell is fixed on the cradle shaft, the lower part of the cradle shaft in the shell is provided with the air cylinder, and the piston rod of the air cylinder drives the yarn shoveling device 5 to enter or exit the rear roller jaw 6 through the connector 3 and the yarn shoveling rod 9, so that the stop feeding and the re-feeding of the roving are realized. When the detection system sends a roving feeding stopping instruction, the air source interface enters air, the air cylinder piston rod retreats to move, the transmission connector 3 and the yarn shoveling rod 9 retreat, and the transmission yarn shoveling device 5 stops roving feeding. When the splicer or an operator sends a roving refeed instruction, the air source interface enters air, the air cylinder piston shaft moves forwards, the transmission connector 3 and the yarn shoveling rod 9 move forwards, and the transmission yarn shoveling device 5 refeeds the roving for feeding.
The second structure is as follows: instead of a cylinder as the actuator 2, the actuator 2 may be an electric cylinder, and the moving member 201 is a piston rod in the electric cylinder.
When the yarn shoveling device works, the piston rod is connected with the yarn shoveling rod, and the piston rod drives the yarn shoveling rod to move. When the electric cylinder works, the piston rod is driven to move back and forth, and then the yarn shoveling rod is driven to move back and forth.
A third structure: as shown in fig. 2, the driver 2 is a two-way electromagnet, and the moving member 201 is an iron core.
The bidirectional electromagnet is electrified with current. When the current direction is opposite, the moving direction of the iron core is also opposite. Therefore, by controlling the direction of current in the bidirectional electromagnet, the change of the moving direction of the iron core is realized. The iron core is opposite to the yarn shoveling rod. By utilizing magnetism, the iron core can drive the yarn shoveling rod to move. When the iron core moves forwards or backwards, the yarn shoveling rod moves forwards or backwards along with the iron core. The yarn shoveling rod is driven to move forwards or backwards, the notch ring yarn shoveling device which is sleeved on the rear roller in an empty way is driven to rotate for a phase position, so that the yarn shoveling device rotates to enter or exit the jaw of the rear roller, and the feeding stopping and re-feeding are realized.
For example, the bi-directional electromagnet is a bi-directionally driven DC electromagnet. And a feeding stopping permanent magnet ring 7 and a compound feeding permanent magnet ring 8 are respectively fixed on two sides of the electromagnet core, the two permanent magnet rings have axial magnetic polarities, and the two permanent magnets are oppositely arranged in the same polarity. When the coil a and the coil b of the electromagnet are connected with a positive b negative direct current power supply, the iron core of the electromagnet moves towards one direction; when the coil a and b ends of the electromagnet are connected and a negative b positive direct current power supply is used, the iron core of the electromagnet moves towards the other direction, so that the connector 3 and the yarn shoveling rod 4 drive the yarn shoveling device 5 to enter or exit the back roller jaw 6, and the stop feeding and the re-feeding of the roving are realized. When the detection system sends a roving feeding stopping instruction, the electromagnet is connected with a positive b negative direct current power supply, so that the electromagnet iron core moves backwards, the transmission connector 3 and the yarn shoveling rod 9 move backwards, and the transmission yarn shoveling device 5 stops feeding the roving. When the splicer or an operator sends a roving refeed instruction, the electromagnet is switched on a positive a negative direct current power supply, the electromagnet core moves forwards, the transmission connector 3 and the yarn shoveling rod 9 move forwards, and the transmission yarn shoveling device 5 refeeds the roving for feeding.
A fourth configuration: as shown in fig. 3 and 4, the actuator 2 includes a first electromagnet 202 and a second electromagnet 203, the moving member 201 includes a first iron core 204 and a second iron core 205, the first iron core 204 is opposite to the first electromagnet 202, and the second electromagnet 203 is opposite to the second iron core 205.
The driver 2 of the third structure is a two-way electromagnet, and the driver 2 of the fourth structure is two electromagnets. The direction of the current passing through the first electromagnet 202 is different from that of the current passing through the second electromagnet 203. Therefore, the moving directions of the first core 204 and the second core 205 are also different. For example, when current is applied to the first electromagnet 202, the first iron core 204 moves rightward as shown in the figure, so that the yarn shoveling rod is driven to move rightward, and feeding stopping is realized. When current in the opposite direction is applied to the second electromagnet 203, the second iron core 205 moves leftwards as shown in the figure, and drives the yarn shoveling rod to move leftwards, so that re-feeding is realized.
The yarn shoveling device is positioned on the yarn shoveling rod, and the yarn shoveling rod is driven to move, the transmission hollow sleeve is arranged on the rear roller, the notch ring yarn shoveling device rotates by a phase position, so that the yarn shoveling device rotates to enter or exit the jaw of the rear roller, and feeding stopping and re-feeding are realized.

The housing 1 is provided for facilitating the connection of the positioning actuator 2 and the mover 201. The driver 2 drives the moving part 201 to move, and one end of the moving part 201 extends out of the shell 1 to drive the yarn shoveling rod to move.

The connector 3 may be connected to the end of the moving member 201 extending out of the housing 1, or may be connected to the end of an external yarn-shoveling rod. The connector 3 functions as a connection. Preferably, the connector 3 is a spring plate. The connector 3 is a spring plate, has certain elasticity and can play a role in buffering.
As a preferred example, the roving automatic stop-feed and re-feed device for the spinning frame further comprises an elastic member 4, and the elastic member 4 is located between the connector 3 and the moving member 201.

The elastic part 4 can play a role in buffering, and the phenomenon that the acting force applied to the external yarn shoveling rod is too large when the moving part 201 moves is avoided. Preferably, the elastic member 4 is a spring or a leaf spring. The spring may be a coil spring. The spring leaf may be a U-shaped spring leaf.
The yarn shoveling rod 9 is connected with the notched circular yarn shoveling device 5, the yarn shoveling rod 9 is provided with an adjusting hole 10, and the positions of the yarn shoveling device 5 and the adjusting hole 10 are adjusted, so that the notch of the yarn shoveling device 5 is positioned at the jaw 6 of the rear roller.
