Description

Technical Field

[0001] The present application relates to the technical field of rubber roller manufacturing equipment, and in particular to a rubber roller vulcanization tank traction device. Background Art

[0002] The rubber roller is a roll-shaped product with a metal or other material as the core and a rubber layer on the outside that is vulcanized. Its processing includes sandblasting of the roller core, bonding treatment, glue forming, vulcanization in a vulcanizing tank and surface processing. The commonly used rubber roller size is 0.5m to 1m. During vulcanization, it is placed on the vulcanizing transfer vehicle and pushed into the vulcanizing tank. Some large rubber rollers used in the packaging industry or printing industry can be more than 3m in length and weigh more than 10 tons. Therefore, large rubber rollers cannot be pushed by manpower when entering the vulcanizing tank, and auxiliary power is required to move the vulcanizing transfer vehicle to enter the tank smoothly.

[0003] For example, a Chinese patent with application number CN202022488857.6 discloses a roller vulcanization conveying device, which drives a flat trolley into a vulcanization chamber through a motor-driven screw. However, the driving motor of the device is installed in the vulcanization chamber. During vulcanization, the vulcanization chamber is in a high temperature, high pressure, and high humidity environment. The motor is easily damaged in such an environment, affecting its service life.

[0004] In order to solve the above problems, people have designed some lifting mechanisms to move the motor. During vulcanization, the motor can be moved out and lifted to avoid being in the tank. However, such a design requires the use of two systems, horizontal and lifting, which increases the difficulty of control. In addition, due to the inability to operate, the horizontal cylinder is extended in advance, which may also cause the connecting sleeve to be damaged. Therefore, a rubber roller vulcanization tank traction device is needed, which uses a single cylinder to achieve the translation and lifting of the drive motor, simplify the operating steps, and reduce equipment failures.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0029] In addition, the descriptions of "first", "second", etc. in this application are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0030] like Figures 1 to 5 As shown, an embodiment of the utility model provides a traction device for a rubber roller vulcanization tank, comprising: a base plate 1, which is installed at the bottom of a foundation pit; a first movable platform 2, which is connected to the base plate 1 through a connecting rod 201; a second movable platform 3, which is slidably connected to the first movable platform 2 through a first slide rail 301; a drive motor assembly 4, which is installed on the upper end surface of the second movable platform 3; wherein both ends of the connecting rod 201 are respectively hinged to the first movable platform 2 and the base plate 1; both ends of the first slide rail 301 are provided with limit blocks; the lower part of the second movable platform 3 is connected to the base plate 1 through a cylinder 5.

[0031] During vulcanization, after opening the cover of the vulcanizing tank, the oil cylinder 5 is controlled to retract, and the first movable platform 2 is pulled by the oil cylinder 5. At this time, the second movable platform 3 drives the first movable platform 2 to move together with the support of the spring rod 302. When the first movable platform 2 moves to contact with the limit pad 801, the first movable platform 2 is limited by the limit pad 801, so that the first movable platform 2 no longer moves. At this time, under the continued pulling of the oil cylinder 5, the second movable platform 3 continues to move forward after overcoming the elastic force of the spring rod 302. At this time, the second movable platform 3 can only move horizontally along the first slide rail 301, so that the latch 303 is inserted into the fixed sleeve 802, and the transmission sleeve 402 is sleeved with one end of the transmission screw 6. After starting the reduction motor 401, the transmission screw 6 can be driven to rotate, and then the tractor 7 is driven to move through the thread, so as to pull the rubber roller transfer vehicle in and out of the vulcanizing tank, thereby lowering the pressure Low manpower consumption. After traction is completed, start the extension of the oil cylinder 5. At this time, since the spring rod 302 is in a compressed state, when the oil cylinder 5 is extended, it will preferentially push the second movable platform 3 to translate so that the latch 303 is separated from the fixed sleeve 802, and the transmission sleeve 402 is separated from the transmission screw 6. When the second movable platform 3 moves to the end of the first slide rail 301, there is no longer any relative movement between the first movable platform 2 and the second movable platform 3. At this time, the oil cylinder 5 drives the first movable platform 2 and the second movable platform 3 to make a circular motion around the connecting rod 201, so that the height of the drive motor assembly 4 is reduced and dropped into the foundation pit, so as to avoid the drive motor assembly 4 blocking the closing of the vulcanization tank cover. During vulcanization, the drive motor assembly 4 is located outside the vulcanization tank, so as to avoid the drive motor assembly 4 being in a high temperature, high humidity and high pressure environment, thereby improving the service life of the drive motor assembly 4.

[0032] When raising, the moving order of the first movable platform 2 and the second movable platform 3 is controlled by the spring rod 302. When the first movable platform 2 is raised to a predetermined position, the second movable platform 3 moves horizontally. When lowering, the moving order is also controlled by the spring rod 302. The second movable platform 3 moves horizontally first, and then the first movable platform 2 rotates. Therefore, only one oil cylinder 5 is needed to complete the lifting and horizontal movement actions, thereby simplifying the equipment structure, reducing the operating steps, and reducing the probability of equipment failure.

[0033] Specifically, Figure 3 , Figure 4 As shown, a spring rod 302 is provided between the first movable platform 2 and the second movable platform 3. When the spring rod 302 is in an extended state, the spring inside the spring rod 302 is in a compressed state, that is, when the spring rod 302 is extended, the spring inside the spring rod 302 needs to be compressed. The spring rod 302 is used to adjust the activity sequence between the first movable platform 2 and the second movable platform 3 to realize the lifting and lowering and horizontal movement of the second movable platform 3.

[0034] Specifically, Figure 2As shown, it also includes a transmission screw 6 and a tractor 7. The transmission screw 6 is installed on the bottom of the vulcanization tank through a bearing seat. A tractor guide rail is provided at the bottom of the vulcanization tank. The tractor 7 slides along the tractor guide rail, and the tractor 7 is connected to the transmission screw 6 through a thread. The tractor 7 is used to tow the rubber roller transfer vehicle. One end of the transmission screw 6 is sleeved with the drive motor assembly 4. The transmission screw 6 and the tractor 7 both adopt the structure of the existing technology. After the transmission screw 6 is driven by the drive motor assembly 4, the tractor 7 can be driven through the thread to make it move axially. The tractor 7 is connected to the rubber roller transfer vehicle through a connecting rod, thereby realizing the pulling in and pulling out of the rubber roller transfer vehicle.

[0035] In a preferred embodiment, Figure 3 As shown, it also includes a connecting frame 8, which is fixed to one end of the vulcanization tank. A limiting pad 801 is provided on the connecting frame 8. When the connecting rod 201 is rotated to be perpendicular to the bottom plate 1, one side of the first movable platform 2 is against one end of the limiting pad 801, and the first movable platform 2 is limited by the limiting pad 801, so that after the first movable platform 2 moves to contact the limiting pad 801, it will no longer move after being limited by the limiting pad 801, thereby providing a supporting force so that the second movable platform 3 can overcome the elastic force of the spring rod 302 and move horizontally.

[0036] In a preferred embodiment, fixed sleeves 802 are provided on both sides of the connecting frame 8, and pins 303 are provided on both sides of the second movable platform 3. After the second movable platform 3 slides to the end of the first slide rail 301, the pin 303 is inserted into the fixed sleeve 802. After the pin 303 is inserted into the fixed sleeve 802, the drive motor assembly 4 can be limited to provide support force to offset the reverse torque applied to the drive motor assembly 4 when rotating the transmission screw 6, thereby ensuring smooth transmission between the drive motor assembly 4 and the transmission screw 6.

[0037] In a preferred embodiment, Figure 3 and Figure 5 As shown, the driving motor assembly 4 includes a reduction motor 401, a transmission sleeve 402, and a gear bracket 403. The reduction motor 401 and the gear bracket 403 are installed on the second movable platform 3, the transmission sleeve 402 is installed on the gear bracket 403, and the output shaft of the reduction motor 401 extends into the gear bracket 403. The reduction motor 401 and the transmission sleeve 402 are both provided with gears, and the gears are meshed with each other. The torque of the reduction motor 401 is large so as to provide sufficient torque to drive the transmission screw 6. The reduction motor 401 and the transmission sleeve 402 adjust the speed and direction through gears, which can reduce the height of the driving motor assembly 4 above the axis of the transmission screw 6 to avoid the drive motor assembly 4 from scratching the bottom of the rubber roller transfer vehicle.

[0038] Specifically, one end of the transmission screw 6 is a rounded rectangle or a regular hexagon, and the inner cavity of the transmission sleeve 402 is matched with the end of the transmission screw 6. When the transmission sleeve 402 is sleeved with the transmission screw 6, the transmission sleeve 402 can transmit the torque of the reduction motor 401 to the transmission screw 6, thereby causing the transmission screw 6 to rotate and drive the tractor 7 to move.

[0039] In a preferred embodiment, the opening ends of the transmission sleeve 402 and the fixed sleeve 802 are both trumpet-shaped, and the trumpet shape has a guiding function. When the transmission screw 6 is docked with the transmission sleeve 402 and the pin 303 is docked with the fixed sleeve 802, the trumpet-shaped opening can be guided to facilitate smooth docking.

[0040] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
