Description

TECHNICAL FIELD

[0001] The utility model relates to a cloth drawing machine technical field, in particular to a cloth drawing machine. BACKGROUND

[0002] The tenter is a kind of equipment in textile printing and dyeing factory, which is used to stretch and flatten fabric by heating and tensioning to the both sides, and make the width of weft direction consistent.

[0003] In the prior art, the tenter is generally a large machine, and requires a wide area and a high workshop requirement, and when adjusting the width of cloth tentering, the distance between the two needle plates needs to be adjusted, which is energy-consuming, noisy and inconvenient to adjust. UTILITY MODEL CONTENT

[0004] The utility model provides a cloth drawing machine to overcome the deficiency that the tenter is generally a large machine in the prior art, and the distance between the two needle plates needs to be adjusted when adjusting the width of cloth tentering, which is energy-consuming, noisy and inconvenient to adjust.

[0005] The utility model provides a cloth drawing machine to overcome the deficiency that the tenter is generally a large machine in the prior art, and the distance between the two needle plates needs to be adjusted when adjusting the width of cloth tentering, which is energy-consuming, noisy and inconvenient to adjust.

[0006] The rotation speed of the multi-groove tube is matched with the fabric feeding speed. During the rotation of the multi-groove tube, the nail plate in the slide is driven to circulate and roll. The fabric spreading machine adjusts the position of the nail plate by adjusting the position of the guide wheel. The nail plate is used to fix the boundary position of the fabric. The two nail plates in the same slide are connected by an elastic rubber strip. The contraction force of the elastic rubber strip presses the guide wheels of the two nail plates on the elastic rubber strip tightly against the first guide surface or the second guide surface. The sensing system is used to sense the boundary position of the fabric in real time. The first drive component is used to synchronously adjust the position of the first guide cylinder according to the fabric boundary sensed by the sensing system. The first guide cylinder is used to capture the guide wheel of the nail plate at the feeding point. During the rotation of the multi-groove tube, the guide wheel is driven to walk on the first guide surface of the first guide cylinder. When it approaches the second guide cylinder, the guide wheel slides onto the second guide surface of the second guide cylinder and is guided by the second guide surface (elliptical inclined plane) to expand the fabric width.

[0007] Before the fabric is expanded, the positions of the two second guide cylinders are adjusted according to the predetermined expansion width of the fabric via two second drive components. The distance between the two points of the two elliptical inclined planes at the outlet, plus the horizontal distance between the two guide wheels and the nails, equals the expansion width of the fabric. It is important to note that the boundary of the fabric should be between the highest and lowest points of the elliptical inclined planes. If the fabric boundary is inside the lowest point of the elliptical inclined plane, the nail plate cannot be fixed to the fabric boundary. If the fabric boundary is outside the highest point of the elliptical inclined plane, the first guide cylinder cannot transfer the guide wheel to the second guide cylinder, thus losing the expansion function.

[0008] Furthermore, the nail plate includes a main board, with the guide wheel and multiple pulleys cooperating with the slide rail below the main board, and a connecting plate above the main board. The connecting plate has a connecting groove that cooperates with the elastic rubber strip, and multiple threaded holes in the connecting groove. Fixing bolts are inserted into the threaded holes. The upper end of the connecting plate has a nail seat, and the upper end of the connecting plate has multiple adjustment holes that cooperate with the nail seat at intervals along the length direction of the main board.

[0009] The elastic rubber strip is inserted into the connecting groove of the connecting plate and fixed by fixing bolts. The deformation force of the elastic rubber strip is mainly concentrated at the connecting groove and fixing bolts, which reduces the damage of nails to the elastic rubber strip and extends its service life. Furthermore, when the elastic rubber strip is damaged at the nail, the service life of the elastic rubber strip can be extended by adjusting the position of the nail seat.

[0010] Further, in order to adjust the position of the first guide cylinder, the first drive assembly comprises a first motor, a first screw rod, a guide rail and an intermediate block, the first motor is fixedly connected to the rack on one side of the multi-groove circular pipe, the intermediate block is arranged at the middle position of the inner side of the multi-groove circular pipe, the first guide cylinder is provided with a first transmission plate, one end of the first screw rod is connected to the output end of the first motor, the other end is rotatably connected to the intermediate block, the first screw rod passes through the first transmission plate and is threadedly connected to the first transmission plate, one end of the guide rail is connected to the intermediate block, the other end is connected to the rack, and the first transmission plate is slidably connected to the guide rail. One first drive assembly can only adjust the position of one first guide cylinder, and the actions of two first drive assemblies are independent of each other, that is, the movements of the two first guide cylinders are independent.

[0011] Further, in order to adjust the position of the second guide cylinder, the second drive assembly comprises a second motor and a second screw rod, the second motor is fixedly connected to the rack at the end of the multi-groove circular pipe, the second guide cylinder is sleeved outside the first guide cylinder, the second guide cylinder is provided with a second transmission plate, one end of the second screw rod is connected to the output end of the second motor, the other end is rotatably connected to the intermediate block, the second screw rod passes through the second transmission plate and is threadedly connected to the second transmission plate, and the second transmission plate is slidably connected to the guide rail. One second drive assembly can only adjust the position of one second guide cylinder, and the actions of two second drive assemblies are independent of each other, that is, the movements of the two second guide cylinders are independent.

[0012] Further, one side of the second transmission plate is provided with a retainer, the retainer comprises a first bearing, the inner ring of the first bearing is fixedly connected to the second transmission plate, the outer ring of the first bearing is supported on the inner side of the multi-groove circular pipe, a plurality of second bearings are arranged on the outer ring of the first bearing in the circumferential direction, and a plurality of sliding grooves matched with the second bearings are arranged on the inner wall surface of the multi-groove circular pipe.

[0013] Since the second guide surface is an inclined surface, when the guide wheel extrudes the second guide surface, the second guide cylinder will have a tendency to tilt to one side. In order to prolong the service life of related parts and ensure the quality of cloth expansion, a retainer is arranged on one side of the second transmission plate of the second guide cylinder to increase the structural stability. When adjusting the position of the second guide cylinder, the retainer moves synchronously with the second guide cylinder through the cooperation of the second bearing and the sliding groove. During work, the inner ring of the first bearing is stationary, and the outer ring is rotatable synchronously with the multi-groove circular pipe through the cooperation of the second bearing and the sliding groove of the multi-groove circular pipe.
