Description

Technical Field

[0001] This utility model relates to the component mechanism of a tire vulcanizing machine, specifically a tire vulcanizing machine translation, lifting and flipping type tire unloading device. Background Technology

[0002] After the tire vulcanizing machine completes the tire vulcanization, the tire needs to be transferred from the vulcanizing chamber to the tire unloading roller conveyor. An automated tire unloading device is required. The traditional tire unloading device completes the tire unloading in three actions, including ① forward and backward translation of the roller arm, ② lifting and lowering of the roller arm, and ③ flipping of the roller arm.

[0003] In traditional tire unloading devices, the roller arm moves to the center of the vulcanizing chamber and inserts into the lower part of the tire. After the roller arm rises to pick up the tire, it flips over, detaching the tire from the central mechanism and allowing it to slide down the roller arm, thus completing the tire unloading process.

[0004] In the structure of a traditional tire unloading device, a roller arm is installed on the flipping shaft. The roller arm enters and exits the vulcanization center by a hydraulic cylinder pushing a moving frame. The moving frame is equipped with a mechanism consisting of connecting rods and rails. Driven by the hydraulic cylinder, the flipping shaft can be raised, lowered, and rotated along the rails. The rotating flipping shaft drives the roller arm to rise, lower, and flip.

[0005] Because traditional tire unloading devices have a complex structure, jamming and wear failures often occur during lifting and tilting. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model proposes a tire vulcanizing machine translation lifting and flipping tire unloading device.

[0007] A tire vulcanizing machine translation, lifting, and tilting tire unloading device that can solve the problems of existing technologies includes a translation mechanism, a lifting mechanism, and a tilting mechanism, the difference being:

[0008] 1. The translation mechanism includes a translation frame, the base plate of which is slidably mounted on the left and right linear guide rails I, and the translation frame moves forward and backward under the drive of the translation cylinder.

[0009] 2. The lifting mechanism includes left and right lifting seats, each lifting seat is slidably installed on the corresponding linear guide rail II, the left and right linear guide rail II are vertically installed on the front plate of the translation frame, the flipping shaft passes through the left and right lifting seats, and a lifting rod is installed on the flipping shaft between the two lifting seats. The lifting rod drives the flipping shaft to move up and down under the drive of the lifting cylinder.

[0010] 3. The flipping mechanism includes left and right tire receiving roller arms mounted on the flipping shaft on the outside of each lifting seat. A cam gear is also mounted on the flipping shaft between the two lifting seats. A rack is vertically mounted on the front plate of the translation frame. The convex part of the cam gear acts on the front plate by the gravity of the front part of the tire receiving roller arm, thereby limiting the tire receiving roller arm to the horizontal position before flipping. In the flipped position, the rack meshes with the teeth of the cam gear to flip each tire receiving roller arm synchronously.

[0011] The beneficial effects of this utility model are:

[0012] This utility model is a tire vulcanizing machine with a horizontal lifting and flipping tire unloading device. Its structure is simple and reliable, which greatly reduces the probability of failure during lifting and flipping. Attached Figure Description

[0017] The technical solution of this utility model will be further described below with reference to the embodiments shown in the accompanying drawings.

[0018] This utility model relates to a tire vulcanizing machine with a translational, lifting, and flipping tire unloading device, which includes a translational mechanism, a lifting mechanism, and a flipping mechanism.

[0019] The carrier of the translation mechanism is a translation frame 1, which includes a base plate and a vertical frame mounted on the base plate. The front end of the vertical frame is a vertical front panel. Two vertical linear guide rails II5 are mounted on the front panel, one on the left and one on the right. A vertical rack 11 is mounted on the upper left side of the front panel between the two linear guide rails II5. A vertical clearance groove is provided on the lower right side of the front panel between the two linear guide rails II5. The base plate is slidably mounted on two horizontal linear guide rails I2, which are mounted on a frame 12. The frame 12 is mounted on the base 13 of the vulcanizing machine. A translation cylinder 3 is provided between the left and right linear guide rails I2, mounted on the base 13 via a cylinder seat. The cylinder rod of the translation cylinder 3 extends backward and is connected to the lower part of the vertical frame of the translation frame 1. Figure 1 , Figure 2 , Figure 3 As shown.

[0020] The lifting mechanism includes left and right lifting seats 4, which are slidably mounted on left and right linear guide rails II 5. A tilting shaft 6 passes through the left and right lifting seats 4, and the structure of the through part is rotatable. The front part of the lifting rod 7 is fitted on the right side of the tilting shaft 6 between the left and right lifting seats 4. The rear part of the lifting rod 7 is located at the rear of the front panel through a clearance groove. Left and right tire receiving roller arms 9 (structural components with a row of rollers, on which the tire can slide forward and backward) are installed on the tilting shaft 6 on the outer side of each lifting seat 4. The front length of each tire receiving roller arm 9 is greater than the rear length. A lifting cylinder 8 is installed inside the vertical frame on the rear side of the front panel. The cylinder body of the lifting cylinder 8 is hinged to the base plate, and the upward-extending cylinder rod of the lifting cylinder 8 is hinged to the rear of the lifting rod 7. Figure 1 , Figure 2 , Figure 3 As shown.

[0021] The flipping mechanism includes a cam gear 10, which is fixedly mounted on the left side of the flipping shaft 6 between the left and right lifting seats 4. The lifting cylinder 8 drives the flipping shaft 6 to move up and down via the lifting rod 7. In the lifting position below the rack 11 (i.e., when the cam gear 10 is disengaged from the rack 11, the flipping shaft 6 rotates counterclockwise under the gravity of the front part of each tire receiving roller arm 9), the convex part of the cam gear 10 acts on the front panel to limit the tire receiving roller arm 9 to a horizontal tire receiving position. In the flipping position where the rack 11 and the cam gear 10 are partially engaged, the clockwise rotation of the cam gear 10 drives the flipping shaft 6 to rotate, and the flipping shaft 6 drives each tire receiving roller arm 9 to flip and tilt backward. The counterclockwise rotation of the cam gear 10 drives each tire receiving arm 9 to return to its original position. Figure 1 , Figure 2 , Figure 3 As shown.

[0022] The operation mode of this utility model is as follows:

[0023] 1. At the initial position of tire removal, the cylinder rod of the translation cylinder 3 extends and moves the translation frame 1 backward to stop outside the vulcanization center, while the cylinder rod of the lifting cylinder 8 retracts and lowers the left and right tire receiving roller arms 9 to the lowest position.

[0024] 2. When unloading the tire, the cylinder rod of the translation cylinder 3 retracts and pulls the translation frame 1 forward into the vulcanization center to pick up the tire. The cylinder rod of the lifting cylinder 8 extends and raises the left and right tire receiving arms 9 to the flip position. The cam gear 10 meshes with the rack 11 and drives the flip shaft 6 to rotate clockwise. The flip shaft 6 drives the left and right tire receiving arms 9 to flip backward to unload the tire.

[0025] 3. After tire removal, the cylinder rod of the lifting cylinder 8 retracts, the left and right tire receiving arms 9 return to the horizontal position and descend to the lowest position, and the cylinder rod of the translation cylinder 3 extends to move the translation frame 1 to the initial position, waiting for the next tire removal operation.
