DETAILED DESCRIPTION

[0011] The present invention will be further described below in conjunction with the accompanying drawings.

[0012] 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, a right supporting seat 3 and a left supporting seat 4 are arranged on the frame 2, and an arc-shaped notch 5 which can support the cloth winding roller 1 is respectively arranged on the right supporting seat 3 and the left supporting seat 4, a right cloth winding roller seat 6 and a left cloth winding roller seat 7 are respectively arranged at both ends of the cloth winding roller 1, the right cloth winding roller seat 6 is rotatably connected with a rotating shaft 8 arranged on the frame 2, and the rotating shaft 8 is connected with a rotating shaft driving mechanism 9 which 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 with a driving shaft 11 arranged on the frame 2, a pair of tenons 12 are symmetrically arranged on the left cloth winding roller seat 7, and a circular positioning boss 13 is arranged at the front end of the pair of tenons 12, and a tenon groove 14 corresponding to the pair of tenons 12 is arranged on the cloth winding roller 1.

[0013] The present invention provides an automatic installation structure for a loom cloth roller 1, 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 of the driving shaft 11, and the right cloth roller seat 6 is a movable end and can rotate freely along the axial direction of the rotating shaft 8.

[0014] Action 1: The manipulator or the cloth drop vehicle places the cloth roll 1 on the left support seat 4 and the right support seat 3, and the semicircular notches on the left support seat 4 and the right support seat 3 automatically position the cloth roll 1.

[0015] Action 2: The rotating shaft 8 is controlled by the rotating shaft driving mechanism 9 to push the right cloth rolling roller seat 6 to translate from right to left. Under the thrust of the right cloth rolling roller seat 6, the left end of the cloth rolling roller 1 is inserted into the circular positioning boss 13 on the left cloth rolling roller seat 7. Then the left end face of the cloth rolling roller 1 is against the end face of the left cloth rolling roller seat 7. At this time, the tenon 12 on the left cloth rolling roller seat 7 is not aligned with the tenon groove 14 on the cloth rolling roller 1. The right cloth rolling roller seat 6 continues to push the cloth rolling roller 1 to compress the corrugated washer 10 to store energy.

[0016] Action 3: As the left cloth roller seat 7 slowly rotates, the tenon 12 on the left cloth roller seat 7 is aligned with the tenon groove 14 on the cloth roller 1, and the corrugated washer 10 is elastically released 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 driven by the left cloth roller seat 7. The driving method of the drive shaft 11 is the same as the structure of the loom in the prior art, and this scheme will not be described in detail here.

[0017] Action 4: The rotating shaft 8 continues to push the right cloth-winding roller seat 6 to translate from right to left until it presses against the cloth-winding roller 1 under the control of the rear mechanism.

[0018] 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.

[0019] 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 by 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 against 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.

[0020] The working principle of the 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, and 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 surface of the cloth rolling roller 1 through the right cloth rolling roller seat 6, so that the cloth rolling roller 1 is axially translated to the left cloth rolling roller seat 7, so that the cloth rolling roller 1 automatically moves to the left, and cooperates with the driving shaft 11 to realize the automatic loading of the cloth rolling roller 1.

[0021] Preferably, the corrugated washer 10 is fixed to the right cloth rolling roller seat 6 by two screws.

[0022] Preferably, the right cloth rolling roller seat 6 is provided with a positioning sleeve 15 which can be sleeved on the right end of the cloth rolling roller 1. The provision of the positioning sleeve 15 can improve the connection stability between the right end surface of the cloth rolling roller 1 and the right cloth rolling roller seat 6.

[0023] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
