[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figure 1 As shown, an automatic installation structure of a cloth winding roller 1 of a loom comprises a cloth winding roller 1 and a frame 2, wherein the frame 2 is provided with a right supporting seat 3 and a left supporting seat 4, and the right supporting seat 3 and the left supporting seat 4 are respectively provided with an arc-shaped notch 5 that can support the cloth winding roller 1, and a right cloth winding roller seat 6 and a left cloth winding roller seat 7 are respectively provided at both ends of the cloth winding roller 1, the right cloth winding roller seat 6 is rotatably connected to a rotating shaft 8 provided on the frame 2, and the rotating shaft 8 is connected to a rotating shaft driving mechanism 9 that can drive the rotating shaft 8 to move left and right, a corrugated washer 10 is fixedly installed on the side of the right cloth winding roller seat 6 facing the cloth winding roller 1, the left cloth winding roller seat 7 is fixedly connected to a driving shaft 11 provided on the frame 2, a pair of tenons 12 are symmetrically provided on the left cloth winding roller seat 7, and a circular positioning boss 13 is provided at the front end of the pair of tenons 12, and a tenon groove 14 corresponding to the pair of tenons 12 is provided on the cloth winding roller 1.

[0026] The present invention provides an automatic installation structure for the cloth roller 1 of a loom, and its working principle is as follows: when the cloth roller 1 is loaded, the loom is required to operate normally, so the left cloth roller seat 7 rotates slowly and uniformly under the drive shaft 11, and the right cloth roller seat 6 is the movable end and can rotate freely along the axial direction of the rotating shaft 8.

[0027] Action 1: The manipulator or cloth drop car places the cloth roller 1 on the left support 4 and the right support 3. The semicircular notches on the left support 4 and the right support 3 automatically position the cloth roller 1.

[0028] Action 2: The rotating shaft 8 is controlled by the rotating shaft driving mechanism 9 to push the right cloth winding roller seat 6 from right to left. Under the thrust of the right cloth winding roller seat 6, the left end of the cloth winding roller 1 is inserted into the circular positioning boss 13 on the left cloth winding roller seat 7. Then the left end face of the cloth winding roller 1 is against the end face of the left cloth winding roller seat 7. At this time, the tenon 12 on the left cloth winding roller seat 7 is not aligned with the tenon groove 14 on the cloth winding roller 1. The right cloth winding roller seat 6 continues to push the cloth winding roller 1 to compress the corrugated washer 10 to store energy.

[0029] Action 3: As the left cloth roller seat 7 slowly rotates, the tenon 12 on the left cloth roller seat 7 aligns with the tenon groove 14 on the cloth roller 1. The wave washer 10 elastically releases and pushes the cloth roller 1 further to the left. At this time, because the cloth roller 1 is engaged with the left cloth roller seat 7, the cloth roller 1 rotates slowly and uniformly under the drive of the left cloth roller seat 7. The drive method of the drive shaft 11 is the same as that of the loom in the prior art and will not be described in detail in this solution.

[0030] Action 4: The rotating shaft 8 continues to push the right cloth winding roller seat 6 from right to left under the control of the rear mechanism until it presses against the cloth winding roller 1.

[0031] The advantage of this solution is that the cloth winding roller 1 can be automatically positioned and installed without manual operation, thus saving manpower and improving the efficiency of the loom.

[0032] Preferably, the shaft driving mechanism 9 includes a servo motor 91, the output shaft of the servo motor 91 is fixedly connected to a pinion 92, the servo motor 91 is fixed to a motor bracket 93 by bolts, the motor bracket 93 is fixed to a loading base 94 by bolts, and the loading base 94 is fixed to the frame 2 by bolts; it also includes a cloth winding roller support 95 fixed to the frame 2 by bolts, the cloth winding roller support 95 is connected to a rotating disk 97 through a ball bearing 96, a rotating shaft 8 is passed through the center of the cloth winding roller support 95 and the rotating disk 97, the rotating disk 97 is threadedly connected to the rotating shaft 8, the end of the rotating shaft 8 can abut the right cloth winding roller seat 6, and a large gear 98 meshing with the pinion 92 is fixedly connected to the outer wall of the rotating disk 97.

[0033] The working principle of the rotating shaft driving mechanism 9 is that the radial rotation of the output shaft of the servo motor 91 drives the radial rotation of the rotating disk 97 through the gear cooperation between the small gear 92 and the large gear 98. The radial rotation of the rotating disk 97 is changed into the axial movement of the transmission screw, that is, the rotating shaft 8 through the spiral transmission. The axial movement of the rotating shaft 8 acts on the right end face of the cloth winding roller 1 through the right cloth winding roller seat 6, so that the cloth winding roller 1 is axially translated to the left cloth winding roller seat 7, so that the cloth winding roller 1 automatically moves to the left, and cooperates with the drive shaft 11 to realize the automatic loading of the cloth winding roller 1.

[0034] Preferably, the wave washer 10 is fixed to the right cloth rolling roller seat 6 by two screws.

[0035] Preferably, the right cloth rolling roller seat 6 is provided with a positioning sleeve 15 tube that can be sleeved on the right end of the cloth rolling roller 1. The setting of the positioning sleeve 15 tube can improve the connection stability between the right end surface of the cloth rolling roller 1 and the right cloth rolling roller seat 6.

[0036] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
