Description

Technical Field

[0001] This utility model relates to the field of fabric feeding, specifically to a feeding device for a weaving machine. Background Technology

[0002] After the loom finishes weaving the fabric, it needs to be transported to the back-end equipment. Since the back-end equipment needs to process the fabric evenly, the fabric transported by the loom also needs to be at a constant speed.

[0003] Current loom feeding devices control the fabric conveying speed by controlling the output speed of the power mechanism. However, the consistency of the output speed of the power mechanism is poor, resulting in technical problems such as variations in the fabric conveying speed. There is an urgent need to design a new feeding device for looms.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

The mounting slots 31 of the upper wheel 11 and the lower wheel 12 provide mounting positions for the upper wheel 11 and the lower wheel 12; the driven member 4 is adapted to be driven to rotate by the fabric feeding mechanism 1, and is used to rotate synchronously with the upper wheel 11 and the lower wheel 12; the detection member 5 is adapted to detect the rotational speed of the driven member 4, and is used to detect the linear velocity of the outer side of the driven member 4, thereby obtaining the rotational speed of the upper wheel 11 and the lower wheel 12, and finally obtaining the fabric conveying speed; the motor 6 provides the power for fabric conveying; the push-pull mechanism 2 is set at the mounting base 3; the detection member 5 and the motor 6 are both electrically connected to the external control system, and are used to control the operation and stop of the components, as well as transmit signals.

[0051] In some embodiments, the central axes of the upper wheel 11 and the lower wheel 12 are both located within the mounting groove 31 to provide the mounting position for both; the push-pull mechanism 2 includes a push-pull member 21 that provides power and a sleeve 22 connected to the central axis of the upper wheel 11 or the lower wheel 12 to adjust the distance between the upper wheel 11 and the lower wheel 12.

[0052] In some embodiments, the upper wheel 11 is located directly above the lower wheel 12 and is used to cooperate with each other to press the fabric; the push-pull member 21 is installed on the side of the mounting base 3; the sleeve 22 is connected to the end of the central shaft of the upper wheel 11 or the lower wheel 12, and the sleeve 22 is also connected to the push rod of the push-pull member 21 to ensure that the push-pull member 21 adjusts the distance between the upper wheel 11 and the lower wheel 12 through the sleeve 22.

[0053] In some embodiments, the push-pull component 21 is a cylinder or electric cylinder used to provide linear thrust and pull force; the sleeve component 22 is annular.

[0054] In some embodiments, the mounting groove 31 extends through the top of the mounting base 3 to facilitate the placement of the upper wheel 11 and the lower wheel 12; the ends of the central shafts of the upper wheel 11 and the lower wheel 12 are connected to the mounting bases 3 on both sides through the mounting groove 31.

[0055] In some embodiments, the central shaft end of the lower wheel 12 contacts the bottom of the mounting groove 31; the central shaft end of the upper wheel 11 is inserted into the sleeve 22, and the upper wheel 11 is adapted to move in the vertical direction of the mounting groove 31 to drive the upper wheel 11 closer to and away from the lower wheel 12.

[0056] In some embodiments, the detection element 5 is mounted on the mounting base 3 on both sides away from the middle of the feeding mechanism 1; the driven element 4 is fitted onto the end of the central shaft of the upper wheel 11 or the lower wheel 12 to ensure that the detection element 5 can detect the signal of the driven element 4; the motor 6 is connected to the end of the central shaft of the upper wheel 11 or the lower wheel 12 through a coupling to provide power.

[0057] In some embodiments, the detection element 5 is a proximity switch, used to detect the signal of the driven element 4 without contact and transmit the detected signal to an external control system; the driven element 4 is provided with evenly distributed protrusions 41, and the driven element 4 is gear-shaped, so as to ensure that the detection element 5 can obtain the rotational speed and linear speed of the outer side of the driven element 4 by sequentially detecting the protrusions 41; the motor 6 is a stepper motor.

[0058] In some embodiments, the detection surface of the detection element 5 faces the protrusion 41 to facilitate the detection of the signal from the protrusion 41; the protrusion 41 is located on the annular side of the driven element 4 away from the mounting base 3; the rotation shaft of the motor 6, the central shaft of the lower wheel 12, and the driven element 4 are concentric to ensure that the motor 6 is suitable for synchronously driving the lower wheel 12 and the driven element 4 to rotate.

[0059] Working principle: Before using the feeding device of the loom, install the feeding device at the fabric output end of the loom; and electrically connect the feeding device to the external control system. When the feeding device is used: under the control of the external control system, the push-pull component 21 pulls the upper wheel 11 away from the lower wheel 12. The operator pulls the fabric between the upper wheel 11 and the lower wheel 12 until the fabric reaches the equipment at the rear end where the fabric is used. Then, under the control of the external control system, the push rod of the push-pull component 21 extends, driving the upper wheel 11 to move towards the lower wheel 12, thereby clamping the fabric between the upper wheel 11 and the lower wheel 12. Then, the motor 6 works to drive the lower wheel 12 to rotate. The lower wheel 12 rotates, causing the fabric to move forward, while the fabric drives the upper wheel 11 to rotate synchronously. During this process, the lower wheel 12 drives the driven member 4 to rotate synchronously. During this process, the detection element 5 intermittently detects the signal of the protruding member 41 and transmits the detected signal to the external control system. The external control system determines the rotational speed of the driven member 4 based on the intermittently received signals from the detection element 5. Since the diameters of the driven member 4 and the lower wheel 12 are constant, the external control system determines the fabric conveying speed based on the signal intervals detected by the detection element 5 of the protruding member 41, thereby controlling the rotational speed of the motor 7 to ensure that the fabric is conveyed at a uniform speed, maintaining the above process until the work is completed.
