[0032] Universal wheels 29 are arranged around the bottom of the tool trolley frame body 30, so as to facilitate the movement of the tool trolley 2 by the staff.

[0033] The unwinding base 1 comprises a feeding mechanism 11 for conveying the tool trolley 2 and a brake mechanism 12 for braking the tool trolley 2.

[0034] The feeding mechanism 11 comprises a base support frame 111, conveying chains 112 are symmetrically arranged inside the base support frame 111, sprockets are arranged in the conveying chains 112 to drive the conveying chains 112 to rotate, connecting shafts 117 are arranged between the sprockets at the same end to connect the sprockets on both sides together, and one end of each connecting shaft 117 is provided with a conveying motor 113 to drive the rotation of the connecting shaft 117. The conveying motor 113 is started to drive the conveying chains 112 to rotate, so as to convey the tool trolley 2 to the upper side of the base support frame 111.

[0035] The seat support frame 111 is provided with a plurality of guide wheels 114 on both sides of the outer side, which are used to support the tool car 2 conveyed by the conveying chain 112, adjust the moving direction of the tool car 2, and ensure that the tool car 2 does not deviate or run off the track during movement.

[0037] The second air cylinder 116 is arranged on one side of the base support frame 111, and is aligned with the side surface of the bottom of the tool car frame body 30. When the tool car 2 is conveyed to the top of the guide opening base 1 by the conveying chain 112, the second air cylinder 116 is started, and the piston rod abuts against the tool car frame body 30, so that when the filling rubber cloth is guided to open, the tool car 2 does not cause a dangerous accident due to the front and back shaking of the spool 21.

[0038] The brake mechanism 12 is arranged above the base support frame 111, and the brake mechanism 12 is aligned with the other flange plate in the spool 21. The brake mechanism 12 comprises a support frame 125 arranged on the base support frame 111, a rotating shaft 124 arranged at the top of the support frame 125, a third air cylinder 123 arranged in the support frame 125, a V-shaped frame 122 hinged to the extension end of the third air cylinder 123, the corner of the V-shaped frame 122 being penetrated by the rotating shaft 124, and a brake wheel 121 arranged at the other end of the V-shaped frame 122. The inner side of the brake wheel 121 is provided with brake pads, and the brake wheel 121 is in contact with the flange plate of the spool 21. The brake mechanism 12 is connected with the gas source. When braking is needed, the control system opens the gas source valve, fills air into the brake mechanism 12, and the brake pads are pushed and gradually in contact with the brake disc as the gas enters. With the increase of the contact area and the friction force, the rotating speed of the spool 21 gradually decreases until it completely stops. Through the accurate adjustment of the pressure and speed of the air filling by the control system, the brake is stable and effective.

[0039] When the conveying chain 112 conveys the tool car 2 up and down, in order to prevent the brake mechanism 12 from hindering the movement of the tool car 2, the piston rod of the third air cylinder 123 is retracted, the V-shaped frame 122 is rotated around the rotating shaft 124, and the brake wheel 121 is separated from the spool 21.

The storage rollers 53 press the filling glue below the storage rollers 53. Because the conveying belt 4 continues to convey the filling glue, a length of the filling glue is stored below the storage rollers 53. When the conveying roller assembly 6 conveys the filling glue, the filling glue in the storage mechanism 5 is stretched. The storage rollers 53 are circularly moved upward around the support seats 51 under the action of the filling glue. The proximity switches 54 in the support seats 51 monitor the connecting rods 52. The proximity switches 54 send relevant signals to the control system. The control system controls the brake mechanism 12 to stop braking the spool 21. The filler cloth winding roller 23 guides the filling glue filler cloth. The conveying belt 4 starts to convey the filling glue. When the conveying roller assembly 6 stops conveying the filling glue, the conveying belt 4 continues to convey the filling glue. The storage rollers 53 press the filling glue below the storage rollers 53 due to the gravity of the storage rollers 53, and store a length of the filling glue. After the proximity switches 54 fail to monitor the relevant signals of the connecting rods 52, the control system controls the brake mechanism 12 to brake the spool 21. The winding motor 26 stops rotating the filler cloth winding roller 23. The conveying belt 4 stops conveying the filling glue.

[0043] The conveying roller group 6 is rotatably arranged on the conveying frame 3, a plurality of conveying rollers are arranged in the conveying roller group 6, two groups of baffle assemblies 61 are symmetrically arranged above the conveying rollers, each group of baffle assemblies 61 comprises two distance-adjustable baffles, the distance between the baffles can accommodate the filling glue, a fourth cylinder 62 for controlling the movement of the baffle assemblies 61 is arranged below the baffle assemblies 61, the fourth cylinder 62 controls the left and right movement of the baffle assemblies 61, and the filling glue in the baffle assemblies 61 moves within the maximum stroke of the fourth cylinder 62, when the filling glue with different distances is attached to the cord layer of the forming drum, the fourth cylinder 62 can be moved forward and backward at the maximum stroke to accurately position the filling glue at the attachment position of the cord layer, so that the position deviation of the filling glue during attachment is avoided, the labor intensity of the workers for manually aligning the filling glue is reduced, the work efficiency is improved, the quality of the final tire is ensured, and the overall performance of the tire is improved.

[0045] The working principle of the utility model is as follows:

[0046] The preparation work is that the worker pushes the tool car 2 to the feeding port of the guide opening base 1, the bottom of the tool car 2 is aligned with the conveying chains 112 on the two sides, the conveying motor 113 is started, the conveying motor 113 drives the conveying chains 112 to rotate, the tool car 2 is conveyed to the upper side of the guide opening base 1, in the conveying process, the guide wheels 114 play the role of limiting and guiding the tool car frame body 30, after the tool car 2 moves to the guide opening base 1, the first cylinder 115 is aligned with the brake lever 22, the brake wheel 121 is aligned with the flange plate of the spool 21, the driving gear 27 is engaged with the driven gear 28, the first cylinder 115 is started, the brake lever 22 is pushed to rotate, the brake lever 22 stops braking the spool 21, the filling glue mat cloth in the spool 21 is sequentially guided through the traction roller group 24 and the supporting roller 25, and the mat cloth is wound on the mat cloth winding roller 23, and the filling glue is conveyed to the conveying mechanism.

[0047] When the filling glue is used to attach the cord fabric, the worker controls the fifth cylinder 63 to drive the driving rod 64 to move through the control system, so that the conveying roller group 6 is aligned with the conveying end of the forming drum, and the conveying roller group 6 conveys the filling glue on the conveying roller to the cord fabric of the forming drum for attachment. As the filling glue on the conveying roller group 6 is conveyed to the forming drum, the stored filling glue in the storage mechanism 5 becomes less, and the filling glue is tensioned, so that the storage roller 53 is lifted.
