Description

Technical Field

[0001] This utility model relates to the field of tire forming drum technology, and in particular to a tire forming drum that can be quickly assembled and disassembled. Background Technology

[0002] A tire forming drum is a piece of equipment or tool used in the tire manufacturing process. Its main function is to assemble and shape the various parts of the tire (such as the tire body and tread) according to a predetermined shape and size. The forming drum is usually a mold with a specific contour. The tire is placed in this mold during the vulcanization process and shaped by heating and pressurizing.

[0003] In the tire manufacturing process, the tire forming drum needs to accurately reflect the final shape and size of the tire to ensure that all parts of the tire can be correctly aligned and fixed. In the existing technology, most tire forming drums can only produce tires of the same size and type. When producing tires of other sizes and types, it is necessary to switch to another machine, which greatly reduces the efficiency of tire production and increases the production cost. It is not practical enough. Therefore, it is necessary to redesign a tire forming drum that can be quickly assembled and disassembled to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tire forming drum that can be quickly assembled and disassembled.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-assembly and detachable tire forming drum includes a base plate. Multiple movable wheels are fixedly mounted on the bottom wall of the base plate. Two slide rails are fixedly mounted on the upper surface of the base plate. Slider blocks are slidably mounted inside each slide rail. Toothed plates are fixedly mounted on the outer walls of each slider. Two rotating shafts are rotatably mounted through the upper surface of the base plate. The ends of both rotating shafts are connected to the toothed plates on the same side via a rotating mechanism. A rotating rod is rotatably mounted on the bottom wall of the base plate via two fixed plates. A motor is fixedly mounted on the outer wall of the rotating rod. The outer wall of the rotating rod is connected to the outer wall of the rotating shaft via an engagement mechanism. A movable frame is mounted on the upper surface of both sliders. A double-ended screw is rotatably mounted inside the movable frame. The rod has a rocker wheel fixedly installed on its outer wall. Two movable sleeves are threadedly installed on the outer wall of the double-ended screw through a limiting mechanism. Connecting sleeves are fixedly installed on the upper surfaces of the two movable sleeves through a connecting mechanism. Connecting rods are slidably installed inside the two connecting sleeves. Half-drums are fixedly installed at the ends of the two connecting rods. Fixed pins are slidably installed on the outer walls of the two connecting sleeves. Insertion holes that mate with the fixed pins on the same side are opened on the outer walls of the two connecting rods. A lever is fixedly installed at the ends of the two fixed pins. Fixed springs are fixedly installed on the outer walls of the two fixed pins. The two ends of the two fixed springs are elastically connected to the bottom wall of the lever on the same side and the outer wall of the connecting sleeve, respectively.

[0007] Preferably, the rotating mechanism includes a spur gear fixedly mounted on the outer wall of the rotating shaft, and the spur gear meshes with the gear plate.

[0008] Preferably, the meshing mechanism includes bevel gears fixedly installed on the outer wall of the rotating rod and the outer wall of the rotating shaft, and the two bevel gears mesh with each other.

[0009] Preferably, the limiting mechanism includes a limiting rod fixedly installed inside the movable frame, the limiting rod sliding through the two movable sleeves.

[0010] Preferably, the connecting mechanism includes a connecting rod fixedly installed on the upper end face of the movable sleeve, and the outer wall of the connecting rod is fixedly connected to the inside of the connecting sleeve.

[0011] Preferably, one of the semi-drum outer walls is fixedly fitted with two inserts, and the other semi-drum outer wall has two insertion ports that mate with the two inserts.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as a fixing pin, a lever, and a fixing spring, the lever is moved to move the fixing pin out of the insertion hole, thereby releasing the fixing of the connecting rod. Then the connecting rod can be pulled out from inside the connecting sleeve, which allows for convenient disassembly and replacement of the half drum of different sizes. This greatly increases the efficiency of tire production and also reduces manufacturing costs. The fixing spring can fix the fixing pin and prevent the half drum on the connecting rod from slipping off, thus increasing its fixing effect.

[0014] 2. By setting up components such as a rotating rod, bevel gear, spur gear, and toothed plate, the rotating rod can drive the rotating shaft on the same side to rotate when it rotates, through the meshing of the bevel gears. When the rotating shaft rotates, it can drive the spur gear and toothed plate to mesh and move together. When the spur gear and toothed plate mesh together, it can drive the slider to move. The movement of the slider can drive the moving frame to move. This allows the entire tire production device to be easily disassembled for maintenance and replacement, increasing its practicality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5A quick-assembly and detachable tire forming drum includes a base plate 1. Multiple casters 2 are fixedly mounted on the bottom wall of the base plate 1. Each caster 2 is a swivel caster, designed to allow 360-degree rotation on a horizontal plane, enabling easy movement in any direction and greatly improving the efficiency of handling and moving objects. Two slide rails 3 are fixedly mounted on the upper surface of the base plate 1. Sliding blocks 4 are slidably mounted inside each slide rail 3. Toothed plates 5 are fixedly mounted on the outer walls of each of the two sliding blocks 4. The upper surface of the base plate 1 rotates through... Two rotating shafts 6 are installed on the bottom plate 1. The ends of the two rotating shafts 6 are connected to the toothed plate 5 on the same side through a rotating mechanism. The rotating mechanism includes a spur gear 7 fixedly installed on the outer wall of the rotating shaft 6. The spur gear 7 meshes with the toothed plate 5. A rotating rod 9 is rotatably installed on the bottom wall of the bottom plate 1 through two fixed plates 8. A motor 10 is fixedly installed on the outer wall of the rotating rod 9. The outer wall of the rotating rod 9 is connected to the outer wall of the rotating shaft 6 through a meshing mechanism. The meshing mechanism includes bevel gears 11 fixedly installed on the outer wall of the rotating rod 9 and the outer wall of the rotating shaft 6. The two bevel gears 11 mesh with each other.

[0023] Two sliders 4 are mounted on the upper surface of a movable frame 12. A double-ended screw 13 is rotatably mounted inside the movable frame 12. A rocker wheel 14 is fixedly mounted on the outer wall of the double-ended screw 13. Two movable sleeves 16 are threadedly mounted on the outer wall of the double-ended screw 13 through a limiting mechanism. The limiting mechanism includes a limiting rod 15 fixedly mounted inside the movable frame 12. The limiting rod 15 slides through the two movable sleeves 16 and can limit the movement of the two movable sleeves 16, so that the two movable sleeves 16 can only move axially along the outer wall of the double-ended screw 13. A connecting sleeve 18 is fixedly mounted on the upper surface of each of the two movable sleeves 16 through a connecting mechanism. The connecting mechanism includes a connecting rod 17 fixedly mounted on the upper surface of the movable sleeve 16. The outer wall of the connecting rod 17 is fixedly connected to the inside of the connecting sleeve 18.

[0024] Both connecting sleeves 18 have connecting rods 19 slidably installed inside them. Both connecting rods 19 have half-drums 20 fixedly installed at their ends.

[0025] When this utility model is in use, the entire device can be easily moved by multiple movable wheels 2. When it is necessary to manufacture a tire, the rotating rocker wheel 14 drives the double-headed screw 13 to rotate. When the double-headed screw 13 rotates, it can drive the two movable sleeves 16 to move relative to each other through the cooperation with the limiting rod 15. The movement of the two movable sleeves 16 can drive the connecting rod 19 to move through the cooperation of the connecting rod 17 and the connecting sleeve 18. When the connecting rod 19 moves, it can drive the half drums 20 on the same side to move closer to each other. Then, the two half drums 20 are spliced ​​together through the cooperation of the two inserts and the corresponding inserts, thereby realizing the manufacture of tires.

[0026] When different sizes of tires need to be manufactured, the lever 22 can be moved to move the fixing pin 21 out of the insertion hole, thereby releasing the fixing of the connecting rod 19. Then the connecting rod 19 can be pulled out from the connecting sleeve 18, which allows for convenient disassembly and replacement of the half drum 20 according to its size, greatly increasing the efficiency of tire production and reducing manufacturing costs. The fixing spring 23 can fix the fixing pin 21 to prevent the half drum 20 on the connecting rod 19 from slipping off, thus increasing its fixing effect. At the same time, the motor 10 can drive the rotating rod 9 to rotate. When the rotating rod 9 rotates, it can drive the rotating shaft 6 on the same side to rotate through the meshing bevel gear 11. When the rotating shaft 6 rotates, it can drive the spur gear 7 and the toothed plate 5 to mesh and move. When the spur gear 7 and the toothed plate 5 mesh, it can drive the slider 4 to move. The movement of the slider 4 can drive the moving frame 12 to move. This allows for convenient disassembly of the entire tire production device for maintenance and replacement, increasing its practicality.
