Description

Technical Field

[0001] This utility model relates to the technical field of material changing devices for tire forming machines, and in particular to a material changing device for tire forming machines. Background Technology

[0002] Tire forming machines are the core equipment in tire manufacturing, used to precisely bond various rubber components (such as tread, sidewall, belt layers, and ply layers) in a specific process sequence to form a complete tire carcass. The technology involves multiple fields, including mechanics, automation, and materials science.

[0003] Existing tire forming machines require continuous transfer of tread material during operation, resulting in continuous consumption of tread material. Current methods use a material changing cart to replenish the tread material, typically placing the rolled-up material on the material roller of the unloading cart. Since the ends of the tread material cannot be secured, they may detach during transport, leading to contamination from contact with the ground and waste. Therefore, existing material changing carts lacking the function of securing tread material are inconvenient to use. To address this, we provide a material changing device for tire forming machines. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing tire forming machines where the material changing cart cannot fix the end of the tire tread material, and to provide a material changing device for tire forming machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a material changing device for a tire forming machine, comprising: a material changing trolley, the top of which is provided with a fixing mechanism, the fixing mechanism including a fixing sleeve, the top of which is provided with a bent rod, a threaded rod sleeved inside the bent rod, the threaded rod being threadedly connected to the bent rod, a pressure plate sleeved on the outer surface of one end of the threaded rod, the threaded rod being rotatably connected to the pressure plate, a pressure block being fixedly connected to the bottom of the pressure plate, a collar sleeved inside the fixing sleeve, the collar being rotatably connected to the fixing sleeve, a ratchet sleeved on the outer surface of the fixing sleeve, the ratchet being fixedly connected to the collar, an auxiliary mechanism provided inside the fixing sleeve, the auxiliary mechanism including a pawl, the pawl being meshed with the ratchet, a rotating rod provided on one side of the pawl, and a torsion spring sleeved on the outer surface of the rotating rod.

[0006] In a preferred embodiment, the fixed sleeve is fixedly connected to the material changing cart, the collar is fixedly connected to the bent rod, and a guide rod is sleeved inside the bent rod.

[0007] In a preferred embodiment, the guide rod is slidably connected to the bent rod, and the guide rod is fixedly connected to the pressure plate.

[0008] In a preferred embodiment, a rotating block is fixedly connected to one end of the threaded rod inside the pressure plate, and the rotating block is rotatably connected to the inner wall of the pressure plate.

[0009] In a preferred embodiment, one end of the threaded rod is provided with a screw block, which is fixedly connected to the threaded rod.

[0010] In a preferred embodiment, one end of the threaded rod is provided with a screw block, which is fixedly connected to the threaded rod.

[0011] In a preferred embodiment, a bearing is fitted onto the outer surface of one end of the rotating rod, and the bearing is placed inside the fixed sleeve.

[0012] In a preferred embodiment, the bearing is fixedly connected to both the inner wall of the fixed sleeve and the outer surface of the rotating rod.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] This invention, through the setting of a fixing mechanism, enables the material changing tread material roll to be fixed at its end when the material changing tread roll is transferred, thus preventing the end of the tread material roll from detaching from the material changing tread roll. Simultaneously, a threaded rod is provided, which can adjust the position of the pressure plate and pressure blocks. The pressure plate can then drive multiple pressure blocks to fix the end of the tread material roll. Furthermore, a ratchet and pawl are provided, and the pawl, with the cooperation of other components of the auxiliary mechanism, limits the ratchet, preventing it from rotating independently. Therefore, the other components of the fixing mechanism, which work in conjunction with the ratchet, remain stable after rotating and adjusting around the tread material roll, allowing for the tight clamping and fixing of the tread material ends in different positions according to actual usage.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a material changing device for a tire forming machine, comprising: a material changing cart 1, a fixing mechanism 2 on the top of the material changing cart 1, the fixing mechanism 2 including a fixing sleeve 21, a bent rod 22 on the top of the fixing sleeve 21, a threaded rod 23 sleeved inside the bent rod 22, the threaded rod 23 being threadedly connected to the bent rod 22, a pressure plate 24 sleeved on the outer surface of one end of the threaded rod 23, the threaded rod 23 being rotatably connected to the pressure plate 24, a pressure block 25 fixedly connected to the bottom of the pressure plate 24, a collar 26 sleeved inside the fixing sleeve 21, the collar 26 being rotatably connected to the fixing sleeve 21, and a ratchet 27 sleeved on the outer surface of the fixing sleeve 21, the ratchet 27 being fixedly connected to the collar 26. The connection and fixing sleeve 21 is provided with an auxiliary mechanism 3 inside. The auxiliary mechanism 3 includes a pawl 31, which is engaged with a ratchet 27. A rotating rod 32 is provided on one side of the pawl 31. A torsion spring 33 is sleeved on the outer surface of the rotating rod 32. The fixing sleeve 21 is fixedly connected to the material changing cart 1. The collar 26 is fixedly connected to the bent rod 22. A guide rod 28 is sleeved inside the bent rod 22. The guide rod 28 is slidably connected to the bent rod 22. The guide rod 28 is fixedly connected to the pressure plate 24. A rotating block 29 is fixedly connected to one end of the threaded rod 23 inside the pressure plate 24. The rotating block 29 is rotatably connected to the inner wall of the pressure plate 24. A screw block 201 is provided at one end of the threaded rod 23. The screw block 201 is fixedly connected to the threaded rod 23.

[0026] In this embodiment, a fixed sleeve 21 is provided and fixedly connected to the main frame of the material changing cart 1. This ensures that the fixed sleeve 21 does not affect other components of the material changing cart 1. Simultaneously, a threaded rod 23 is provided, which can rotate and move in conjunction with the bent rod 22, driving the rotating block 29 to rotate inside the pressure plate 24. Thus, the threaded rod 23 can adjust the positions of the pressure plate 24 and the pressure block 25, allowing them to tightly press and fix the end of the tire tread material. Furthermore, the pressure block 25 can partially... The tread material is embedded inside the fixing mechanism 2 to make the fixing mechanism 2 more secure to the end of the tread material. At the same time, a collar 26 is provided, and the collar 26 is partially embedded inside the fixing sleeve 21, so that the collar 26 will not slip when rotating around the fixing sleeve 21. In addition, a ratchet 27 is provided, and the ratchet 27 can rotate in one direction with the cooperation of the pawl 31. This allows the position of the pressure plate 24 and the pressure block 25 to be adjusted around the tread material roll, so that the pressure plate 24 and the pressure block 25 can be fixed according to the position of the end of the tread material.

[0027] Example 2

[0028] like Figures 1-3 As shown, the rotating rod 32 is fixedly connected to the pawl 31, and the two ends of the torsion spring 33 are fixedly connected to the outer surface of the pawl 31 and the inner wall of the fixed sleeve 21, respectively. A bearing 34 is sleeved on the outer surface of one end of the rotating rod 32. The bearing 34 is placed inside the fixed sleeve 21, and the bearing 34 is fixedly connected to both the inner wall of the fixed sleeve 21 and the outer surface of the rotating rod 32.

[0029] In this embodiment, by setting an auxiliary mechanism 3, which can work with the ratchet 27, the ratchet 27 will not rotate on its own. At the same time, a torsion spring 33 is set, which can generate elastic force after being twisted and deformed. The elastic force of the torsion spring 33 can act on the pawl 31, so that the pawl 31 can automatically reset in time after slight rotation.

[0030] Working principle:

[0031] like Figures 1-5As shown, in use, the present invention can first rotate the screw block 201, which drives the threaded rod 23 to rotate. The threaded rod 23 can rotate and move under the action of the bent rod 22, and the threaded rod 23 can drive the rotating block 29 to rotate inside the pressure plate 24. Thus, the position of the pressure plate 24 and the pressure block 25 can be changed, moving them away from the material roller of the tire tread material of the material changing car 1. Then, the tire tread material is wound onto the material roller of the material changing car 1. At this time, the position of the pressure plate 24 and the pressure block 25 is adjusted so that they rotate around the tire tread material roll. First, the bent rod 22 is rotated, which drives the collar 26 to rotate around the fixed sleeve 21. At the same time, the collar 26 drives the ratchet 27 to rotate counterclockwise, and the ratchet 27 can slightly squeeze the pawl 31 when rotating, so that the pawl 31 can rotate slightly under the cooperation of the rotating rod 32 and the bearing 34. Thus, the limiting of the pawl 31 by the rotating rod 32 can be temporarily eliminated. The pawl 31 can stretch and deform the torsion spring 33 when it rotates, and the torsion spring 33 can generate elastic force. The elastic force of the torsion spring 33 can be released instantly when the pawl 31 is not squeezed by the ratchet 27, and the pawl 31 can automatically reset, so that the pawl 31 can restrict the ratchet 27. Thus, the ratchet 27 can adjust the position of the pressure plate 24 and the pressure block 25 appropriately when it rotates intermittently. Then, by rotating the screw block 201 again, the threaded rod 23 can rotate in the opposite direction. Thus, the threaded rod 23 can adjust the position of the pressure plate 24 with the cooperation of the guide rod 28, so that the pressure plate 24 can drive the pressure block 25 to move towards the end of the tread material until the pressure plate 24 and the pressure block 25 squeeze and fix the end of the tread material. The pressure block 25 can be partially embedded into the interior of the tread material without damaging the tread material. Thus, the end of the tread material can be in a stable state. Then, the material changing cart 1 can transfer the tread material roll and feed it to the tire forming machine.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
