Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, 2 and 3, the invention provides a lace feeding machine, which comprises a machine frame main body 1, lace storage mechanisms 2 for placing lace raw materials and lace conveying devices for controlling lace conveying, wherein the machine frame main body is provided with a plurality of lace storage mechanisms 2;

the lace storage mechanism comprises a rack main body 1 and lace storage mechanisms 2, wherein the rack main body 1 is provided with a material placing area 9 used for arranging the lace storage mechanisms 2 in a layering mode, and the lace storage mechanisms 2 between two adjacent layers are arranged in a staggered mode, so that lace storage mechanisms are distributed above two lace storage mechanisms on the lower layer, and the problem that the distance between lace belts generated between the two adjacent lace storage mechanisms is too large is solved.

The lace conveying device comprises a driving roller 3 for actively drawing a lace belt and a tension compensation device for controlling the driving roller to rotate 3;

the tension compensation device comprises a swinging piece 4 and an inductive switch 5 corresponding to the swinging piece, wherein the inductive switch 5 controls the rotation of the driving roller, and the lace belt passes through the driving roller 3 and then bypasses the bottom of the swinging piece 4 to be sent out.

Specifically, the lace storage mechanism 2 comprises a storage barrel 21, a rotating shaft 22 arranged at two ends of the storage barrel 21 and a bearing plate 23 used for supporting the rotating shaft, wherein the storage barrel 21 is placed on the bearing plate 23 through the rotating shaft 22.

Referring to fig. 4, in order to facilitate taking out the storage drum 21 for supplementing the lace roll coil for production, a roller set for supporting the rotating shaft 22 is arranged at the top of the supporting plate 23, and the rotating shaft 22 is supported between the two roller sets. Therefore, the storage barrel 21 can be directly taken out without being influenced by other lace storage mechanisms. The roller group comprises an inner roller 231, an outer roller 232 and a roller shaft 233, and the inner roller 231 and the outer roller 232 are respectively arranged on the inner side and the outer side of the bearing plate 23 through the roller shaft 233; in addition, in order to avoid the safety problem of the roller shaft 233, the left end and the right end of the supporting plate 23 extend upwards to form limiting columns 234, a detachable closing rod 235 is arranged between the two limiting columns, and when the roller shaft needs to be replaced, the closing rod 235 is opened. The closing rod 235 can be magnetically attracted or connected with the limiting column by a single-side hinge to close the roller shaft 233 so as to limit the separation.

Because different types of lace have different elasticity changes based on different shapes, patterns and materials, in order to adapt to the requirements of combined sewing production of different types of lace, particularly lace with different elasticity, the roller set is at least provided with a brake assembly 6 for blocking the rotation of the outer roller, the brake assembly 6 comprises a handle screw 61 and a pressure spring 62, and the handle screw 61 passes through the pressure spring 62 and is arranged on the roller shaft 233. Therefore, the friction force between the pressure spring 62 and the outer roller 232 can be adjusted by screwing the handle screw 61, the discharging rotation speed of the storage cylinder 21 is controlled, and the tightness of the lace belt of the storage cylinder 21 during discharging is adjusted. Therefore, the brake assembly 6 can realize the uniformity of different types of lace belts on the tension degree, thereby facilitating the uniform adjustment of the tension compensation device.

Further, the frame body 1 further comprises a first belt winding roller 11 corresponding to the lace storage mechanism 2 and a second belt winding roller 12 arranged on one side of the driving roller 3, and the lace belt sequentially bypasses the first belt winding roller 11, the driving roller 3 and the second belt winding roller 12 so as to be attached to the driving roller 3. The number of the first tape winding rollers 11 corresponds to the number of layers for arranging the lace storage mechanism 2.

The frame body 1 is provided with a supporting column 13 for mounting the first and second belt winding rollers 11 and 12, and the supporting column 13 is provided with a mounting groove 131 for adjusting the mounting heights of the first and second belt winding rollers 11 and 12. Therefore, the first belt winding roller 11 and the second belt winding roller 12 can move up and down along the installation groove 131, so that the attaching area between the lace and the driving roller 3 is adjusted to change the maximum traction force of the driving roller 3 on the lace. The driving roller 3 is preferably a rubber covered roller so as to increase the friction force between lace belts. Moreover, in order to improve the overall synchronism of the lace when the lace is wound through the first belt winding roller 11 and the second belt winding roller 12 so as to reduce the stretching influence on the lace, a synchronous belt 8 is arranged between the first belt winding roller 11 and the second belt winding roller 12 so as to maintain the synchronous rotation between the first belt winding roller and the second belt winding roller. The shaft diameters of the first belt winding roller and the second belt winding roller are equal.

In terms of the drive control of the drive roll 3, the frame body 1 is provided with a support rod 7 corresponding to the second belt winding roll 12, and the swinging member 4 is located below between the support rod 7 and the second belt winding roll 12. The swing member 4 includes a swing shaft 41 mounted on the frame body and a baffle 42 connected to the swing shaft 41, and the sensing switch is disposed at one side of one end of the baffle 42 to sense the swing of the baffle 42. It should be noted that the main traction force of the lace belt generally comes from the processing equipment in butt joint with the lace belt, so that in the case that the driving roller 3 does not work, the natural discharging speed of the lace storage mechanism 2 lags behind the transportation speed of the processing equipment, so that the lace belt is greatly deformed in the discharging process, and finally the lace belt processed by the subsequent processing equipment is processed under the condition of large deformation, thereby affecting the representation of the pattern and the shape of the lace belt.

Therefore, when the discharging speed of the invention is too slow relative to the butt joint processing equipment, the lace belt is tightened to generate a tendency of supporting the swinging piece 4, so that the swinging piece swings to change the initial position of the swinging piece, and the induction switch is triggered to control a motor (not marked in the figure) for rotating the driving roller 3 so as to increase the discharging speed of the lace belt, thereby controlling the difference between the discharging speed of the invention and the conveying speed of the butt joint equipment and avoiding the condition that the lace belt is excessively stretched. Preferably, the inductive switch is a proximity sensor.

And a trough 14 for limiting the lace belt from falling to the ground is arranged at the bottom of the machine frame main body 1. Therefore, when the lace belt between the device and the butt joint equipment is disconnected, the lace belt falls back on the trough 14, and therefore the lace belt is prevented from being polluted by the ground.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
