Description

Technical Field

[0001] The invention relates to the technical field of tire production, in particular to a central mechanism of a vulcanizing machine for tire manufacturing. Background Art

[0002] The center mechanism of the vulcanizer is a device dedicated to tire production. It is a center mechanism designed for motorcycle tire vulcanizers, also known as bladder manipulators. The center mechanism of the vulcanizer is used to support semi-finished tires and air bags, supply air to the air bags and ensure that the tires are fully vulcanized and shaped.

[0003] Its working principle is: first, use the oil cylinder to push the center rod up; then use the mechanical gripper to grab the tire processed in the previous process to the center rod of the central mechanism of the vulcanizer; use the oil cylinder to drive the ring seat to rise to support the airbag and the edge of the tire, and inflate the airbag; after vulcanization, the tire is shaped and the airbag is deflated; start the mechanical gripper to grab the tire and the airbag; the center rod and the ring seat descend at the same time and separate from the tire; the robot grabs the tire and transports it to the next process.

[0004] The central mechanism of the vulcanizer often has to withstand high temperatures when working. Since the central mechanism of the vulcanizer needs to withstand high temperature and high pressure environment when working, its internal rubber gaskets, non-metallic materials and other components are prone to accelerated aging due to high temperature, resulting in performance degradation or even failure. Although these components are not expensive, the central mechanism needs to be disassembled when replaced, which increases maintenance costs and time. However, the central mechanism needs to be disassembled when replaced, and the working steps are cumbersome. At the same time, metal parts such as center rods and hydraulic cylinders may also deform due to thermal expansion when working at high temperatures for a long time, thereby affecting the accuracy and stability of the equipment. Summary of the invention

Since the central mechanism of the vulcanizer needs to withstand a high temperature and high pressure environment during operation, its internal rubber gaskets, non-metallic materials and other components are easily accelerated due to high temperature. The aging, resulting in performance degradation or even failure, although the cost of these components is not high, the central mechanism needs to be disassembled when replaced, which increases the maintenance cost and time. However, the central mechanism needs to be disassembled when replaced, and the working steps are cumbersome. At the same time, metal parts such as center rods and hydraulic cylinders may also be deformed due to thermal expansion when working at high temperatures for a long time, thereby affecting the accuracy and stability of the equipment. A central mechanism of a vulcanizer for tire manufacturing is proposed.

[0016] In summary, due to the adoption of the above-mentioned technology, the central mechanism of a tire vulcanizer for manufacturing has the following beneficial effects: 1. Turn on the water pump, and the cooling water enters the water cavity along the water inlet pipe. The flowing cooling water absorbs the heat of the central mechanism when it is working and discharges it along the water outlet pipe, thereby achieving a good cooling effect, slowing down the wear and aging of internal components, and extending the life of the equipment. At the same time, it makes the internal temperature uniform during operation and improves the working stability. At the same time, the spiral guide plate can extend the time for the cooling water to flow in the water cavity, so that the cooling water can absorb and take away the heat from the central mechanism more evenly, further improving the cooling effect and protecting the service life of the equipment.

[0017] 2. The cooling water is discharged along the outlet pipe and enters the spiral tube. After being sufficiently cooled in the spiral tube, it enters the rotating drum. The semiconductor refrigeration plate switch is turned on, and the cooling surface of the semiconductor refrigeration plate further cools the cooling water in the rotating drum. At the same time, the setting of the spiral plate can allow the cooling water to have sufficient time to contact with the semiconductor refrigeration plate. The cooled cooling water enters the water inlet pipe again for circulation and cooling.

[0018] 3. Start the motor, which drives the blades to rotate so that the airflow goes along wind tube three into wind tube two and then into wind tube one. After the airflow enters wind tube one, the air flow is accelerated, which takes away the heat of the cooling water in the spiral tube and speeds up the cooling efficiency of the cooling water.

[0019] 4. Because the diameter of wind tube three is larger than that of wind tube two, when the airflow enters wind tube two along wind tube three, it will be accelerated. When the airflow in wind tube two enters wind tube one, because the inner diameter of wind tube two is larger than that of wind tube one, the airflow will be accelerated again, thereby increasing the airflow velocity and taking away the heat of the cooling water in the spiral tube more quickly.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical embodiment of the present invention, a tire manufacturing vulcanizer center mechanism. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1 - Fig. 9As shown, the present invention adopts the following technology: a central mechanism of a vulcanizer for tire manufacturing: including a central mechanism body 10, and also including: a cooling component 20 assembled on the central mechanism body 10, the cooling component 20 includes a water cavity 21 opened in the central mechanism body 10 for cooling water to flow, a water inlet pipe 22 connected to the water cavity 21 is fixedly installed on the central mechanism body 10, a water pump 25 is arranged on the water inlet pipe 22, a water outlet pipe 23 connected to the water cavity 21 is fixedly installed on the central mechanism body 10, and a spiral guide plate 24 for increasing the retention time of cooling water is fixedly installed in the water cavity 21; During operation, the water pump 25 is turned on, and the cooling water enters the water cavity 21 along the water inlet pipe 22. The flowing cooling water absorbs the heat of the central mechanism body 10 during operation and is discharged along the water outlet pipe 23, thereby achieving a good cooling effect, slowing down the wear and aging of internal components, and extending the life of the equipment. At the same time, the internal temperature is uniform during operation, and the working stability is improved. At the same time, the spiral guide plate 24 can extend the time for the cooling water to flow in the water cavity 21, so that the cooling water can more evenly absorb and take away the heat on the central mechanism, further improving the cooling effect and protecting the service life of the equipment.

[0024] It should be noted that the spiral guide plate 24 is made of copper; while guiding the flow of cooling water, the spiral guide plate 24 can also directly absorb the heat on the central mechanism body 10, increase the contact area of ​​the cooling water, and further accelerate the cooling.

[0025] It should be noted that the cooling component 20 also includes a plurality of rotating shafts 26 rotatably mounted on the spiral guide plates 24, and a spoiler 27 is fixedly mounted on the rotating shafts 26; when the cooling water flows between the spiral guide plates 24, it can drive the spoiler 27 and the rotating shaft 26 to rotate, so as to further disturb the water flow, accelerate the heat absorption efficiency of the cooling water, and improve the cooling effect.

[0026] A circulation assembly 30 is mounted on the water outlet pipe 23, the circulation assembly 30 includes a spiral tube 32 fixedly mounted on the water outlet pipe 23, a rotating drum 31 is fixedly mounted on one end of the spiral tube 32 away from the water outlet pipe 23, the rotating drum 31 is fixedly connected and communicated with the water inlet pipe 22, the circulation assembly 30 also includes a spiral plate 34 fixedly mounted in the rotating drum 31, a semiconductor refrigeration sheet 33 is fixedly mounted on the rotating drum 31, and the cooling surface of the semiconductor refrigeration sheet 33 is located in the rotating drum 31, so that the cooling water can be recycled after cooling, thereby reducing the waste of water resources; The cooling water is discharged along the water outlet pipe 23 and enters the spiral tube 32. After being sufficiently cooled in the spiral tube 32, it enters the rotating cylinder 31. The switch of the semiconductor refrigeration plate 33 is turned on, and the cooling surface of the semiconductor refrigeration plate 33 further cools the cooling water in the rotating cylinder 31. At the same time, the setting of the spiral plate 34 can allow the cooling water to have sufficient time to contact with the semiconductor refrigeration plate 33. The cooled cooling water enters the water inlet pipe 22 again for circulation cooling.

[0027] The central rotating cylinder 31 is provided with a cooling assembly 40, and the cooling assembly 40 includes a wind cylinder 1 41 fixedly mounted on the central rotating cylinder 31, a wind cylinder 2 42 fixedly mounted on the wind cylinder 1 41, a wind cylinder 3 46 fixedly mounted on the wind cylinder 2 42, a mounting rod 43 fixedly mounted inside the wind cylinder 3 46, a motor 44 fixedly mounted on the mounting rod 43, a blade 45 fixedly mounted on the output shaft of the motor 44, and the spiral tube 32 is located inside the wind cylinder 1 41; The motor 44 is started, and the motor 44 drives the blades 45 to rotate so that the airflow enters the wind tube 2 42 along the wind tube 3 46 and then enters the wind tube 1 41. After the airflow enters the wind tube 1 41, the air flow is accelerated to take away the heat of the cooling water in the spiral tube 32, thereby accelerating the cooling efficiency of the cooling water; It should be noted that the diameter of wind tube three 46 is larger than that of wind tube two 42, and the inner diameter of wind tube two 42 is larger than that of wind tube one 41; because the diameter of wind tube three 46 is larger than that of wind tube two 42, when the airflow enters wind tube two 42 along wind tube three 46, it will be accelerated, and when the airflow in wind tube two 42 enters wind tube one 41, because the inner diameter of wind tube two 42 is larger than that of wind tube one 41, the airflow will be accelerated again, thereby increasing the airflow velocity and taking away the heat of the cooling water in the spiral tube 32 more quickly.

[0028] The anti-leakage component 50 assembled on the water outlet pipe 23 prevents the waste of water resources caused by water leakage due to looseness between the central mechanism body 10 and the water outlet pipe 23. The anti-leakage component 50 is arranged on the water outlet pipe 23, and the anti-leakage component 50 includes a mounting tube 51 fixedly mounted on the water outlet pipe 23, an extension cover 52 is fixedly mounted on the mounting tube 51, and water-expandable glue 54 is arranged in the mounting tube 51; When there is a gap leaking between the water outlet pipe 23 and the central mechanism body 10, the cooling water will enter the installation tube 51 and contact the water-swellable glue 54, causing it to expand and enter the extension cover 52 and finally abut against the gap, playing a pre-blocking effect, avoiding water leakage during the operation of the central mechanism body 10, resulting in uneven temperature on the central mechanism body 10 and reduced tire vulcanization quality, while avoiding damage to the components of the central mechanism body 10; It should be noted that the diameter of the installation tube 51 is larger than that of the extension cover 52 . Therefore, during the expansion process, the water-swellable adhesive 54 can be more densely filled into the extension cover 52 , thereby achieving a better blocking effect.

[0029] A partition 53 is slidably installed in the installation tube 51, and the water-swellable glue 54 is arranged on the partition 53. A plurality of pressure switches 56 are fixedly installed in the installation tube 51, and a warning light bead 57 is arranged on the pressure switch 56; when the water-swellable glue 54 expands, it drives the partition 53 to move and squeezes the pressure switch 56. After the pressure switch 56 is squeezed, the warning light bead 57 lights up to remind the staff to carry out maintenance, which is convenient for equipment maintenance and prolongs the service life of the equipment.

[0030] The water-swellable adhesive 54 is provided with a plurality of water seepage holes 55 , which can increase the contact area between the water-swellable adhesive 54 and water, thereby improving the expansion effect of the water-swellable adhesive 54 and further achieving a better blocking effect.

[0031] Working principle: Turn on the water pump 25, and the cooling water enters the water cavity 21 along the water inlet pipe 22. The flowing cooling water absorbs the heat of the central mechanism body 10 when it is working and is discharged along the water outlet pipe 23, thereby achieving a good cooling effect, slowing down the wear and aging of internal parts, and extending the life of the equipment. At the same time, it makes the internal temperature uniform during operation and improves the working stability. At the same time, the spiral guide plate 24 can extend the time for the cooling water to flow in the water cavity 21, so that the cooling water can more evenly absorb and take away the heat on the central mechanism, further improving the cooling effect and protecting the service life of the equipment. The spiral guide plate 24 can not only guide the cooling water flow, but also directly absorb the heat on the central mechanism body 10, thereby increasing the contact area of ​​the cooling water and further accelerating the cooling; When the cooling water flows between the spiral guide plates 24, it can drive the spoiler plates 27 and the rotating shaft 26 to rotate, thereby further disturbing the water flow, accelerating the heat absorption efficiency of the cooling water, and improving the cooling effect; The cooling water is discharged along the water outlet pipe 23 and enters the spiral tube 32. After being sufficiently cooled in the spiral tube 32, it enters the middle drum 31. The switch of the semiconductor refrigeration plate 33 is turned on. The cooling surface of the semiconductor refrigeration plate 33 further cools the cooling water in the middle drum 31. At the same time, the setting of the spiral plate 34 allows the cooling water to have sufficient time to contact with the semiconductor refrigeration plate 33. The cooled cooling water enters the water inlet pipe 22 again for circulation cooling. The motor 44 is started, and the motor 44 drives the blades 45 to rotate so that the airflow enters the wind tube 2 42 along the wind tube 3 46 and then enters the wind tube 1 41. After the airflow enters the wind tube 1 41, the air flow is accelerated to take away the heat of the cooling water in the spiral tube 32, thereby accelerating the cooling efficiency of the cooling water; Since the diameter of the wind tube 3 46 is larger than that of the wind tube 2 42, when the airflow enters the wind tube 2 42 along the wind tube 3 46, it will be accelerated. When the airflow in the wind tube 2 42 enters the wind tube 1 41, since the inner diameter of the wind tube 2 42 is larger than that of the wind tube 1 41, the airflow will be accelerated again, thereby increasing the airflow speed and taking away the heat of the cooling water in the spiral tube 32 more quickly. When there is a gap leaking between the water outlet pipe 23 and the central mechanism body 10, the cooling water will enter the installation tube 51 and contact the water-swellable glue 54, causing it to expand and enter the extension cover 52 and finally abut against the gap, playing a pre-blocking effect, avoiding water leakage during the operation of the central mechanism body 10, resulting in uneven temperature on the central mechanism body 10 and reduced tire vulcanization quality, while avoiding damage to the components of the central mechanism body 10; A partition 53 is slidably installed in the installation tube 51, and the water-swellable glue 54 is arranged on the partition 53. A plurality of pressure switches 56 are fixedly installed in the installation tube 51, and a warning light bead 57 is arranged on the pressure switch 56; when the water-swellable glue 54 expands, it drives the partition 53 to move and squeeze the pressure switch 56. After the pressure switch 56 is squeezed, the warning light bead 57 lights up to remind the staff to carry out maintenance, which is convenient for equipment maintenance and prolongs the service life of the equipment; The contact area between the water-swellable adhesive 54 and water can be increased, thereby improving the expansion effect of the water-swellable adhesive 54 and further achieving a better blocking effect.
