Description

Technical Field

[0001] This utility model relates to the field of code disk technology, specifically to a code disk lifting device. Background Technology

[0002] In tire production, after the masterbatch rubber is fully loaded into the reel, 6-7 empty reels need to be stacked vertically. This process is called stacking. Automatic stacking relies primarily on the action of a lifting device. Initially, the device's gripper retracts. Once an empty reel is in place, the gripper extends and rises under the first crossbeam of the reel, raising the reel one reel's height. This allows the second empty reel to enter directly below the first. The gripper then retracts and descends, placing the first empty reel on top of the second. When the gripper is low enough to pick up the second reel, it extends and lifts it up along with the first reel, completing the stacking of two reels. Similarly, stacking is complete when 6-7 empty reels are stacked. Currently, the gripper in this process uses an electric motor for extension and retraction. However, frequent motor-driven extension and retraction can easily cause damage, affecting production efficiency and continuity.

[0003] Based on the above drawbacks, the structure and operation of the lifting device were improved. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a code disk lifting device.

[0005] The technical solution of this utility model is: a code disk lifting device, comprising two sets of lifting components symmetrically arranged. Each lifting component includes a column, a lifting frame, a rotating shaft, a gripper, and an adjusting rod. The two columns are arranged side by side, and vertical guide rails are provided on their opposite surfaces. The front and rear sides of the lifting frame are slidably connected to the corresponding guide rails. The rotating shaft is longitudinally installed at the bottom of the lifting frame base plate, with a gap between them. At least two grippers are fixed side by side on the rotating shaft, with the center of gravity of the gripper located at the front and a limiting block provided at its rear end. When the limiting block contacts the lifting frame base plate, the gripper is in a horizontal state.

[0006] A horizontal mounting plate is installed between the lower sides of the two columns, and multiple adjusting rods are installed vertically on the mounting plate in a row, corresponding one-to-one with the gripper handle; the adjusting rods can be adjusted up and down on the mounting plate, and their upper ends face the front side of the gripper handle.

[0007] Preferably, the lifting frame is square, with multiple pairs of guide wheels for clamping the guide rails on the outer sides of both the front and rear plates, and multiple support wheels that roll in contact with the guide rails in the middle of both plates; the support wheels are arranged perpendicularly to the guide wheels.

[0008] Preferably, the lifting frame base plate is equipped with multiple limiting plates corresponding to the grabbers, and the front end of the limiting plate protrudes from the lifting frame base plate to limit the upward tilt of the grabbers.

[0009] Preferably, the adjusting rod is a threaded rod that passes through the mounting plate and is mounted on the mounting plate by two nuts.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] This device replaces the original method of controlling the extension and retraction of the gripper with a new type of gripper, a rotating shaft, an adjusting rod, and a limiting plate. This solves the problem of damage caused by frequent motor-driven extension and retraction. The new gripper has a long service life, a simple structure, and is easy to implement, greatly ensuring the continuity of production. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0017] Reference Figure 1-2 As shown, a code disk lifting device includes two symmetrically arranged lifting components. Each lifting component includes a column 1, a lifting frame 3, a rotating shaft 4, a gripper 5, and an adjusting rod 8. The two columns 1 are arranged side by side, and each of their opposite surfaces is provided with a vertical guide rail 2. The front and rear sides of the lifting frame 3 are slidably connected to the corresponding guide rails 2. The rotating shaft 4 is longitudinally installed at the bottom of the base plate of the lifting frame 3, with a gap between them. The two grippers 5 are fixed side by side on the rotating shaft 4, with the center of gravity of the gripper 5 located at the front side and a limiting block 6 provided at its rear end. When the limiting block 6 contacts the base plate of the lifting frame 3, the gripper 5 is in a horizontal state.

[0018] A horizontal mounting plate 7 is installed between the lower sides of the two columns 1. Two adjusting rods 8 are installed vertically on the mounting plate 7 side by side, and correspond one-to-one with the gripper 5. The adjusting rods 8 can be adjusted up and down on the mounting plate 7, and their upper ends face the front of the gripper 5.

[0019] More specifically, two limiting plates 12 are installed on the bottom plate of the lifting frame 3, which correspond one-to-one with the grabber 5. The front end of the limiting plate 12 protrudes from the bottom plate of the lifting frame 3 to limit the upward tilt of the front side of the grabber 5.

[0020] Action process: Initially, such as Figure 3 As shown, the gripper 5 is held in place by the adjusting rod 8, and its upper side contacts the front end of the limiting plate 12, so that the distance between the two grippers 5 is greater than the length of the rubber disc 13. When the empty rubber disc 13 enters, it will not be blocked. After the rubber disc 13 is in place, the two lifting frames 3 rise synchronously, and the rotating shaft 4 rotates under the gravity of the gripper 5 until the limiting block 6 at the rear end of the gripper 5 is blocked by the bottom plate of the lifting frame 3. The gripper 5 then lifts the empty rubber disc 13 horizontally, allowing time for the next empty rubber disc 13 to enter. When the next empty rubber disc 13 enters, the gripper 5 descends, and the first rubber disc 13 lands directly above the second. When the gripper 5 passes the bottom beam of the rubber disc 13, it is as if... Figure 2 As shown, repeating the above steps will complete the encoder operation.

[0021] This device replaces the original method of controlling the extension and retraction of the gripper 5 by using a new type of gripper 5 and a rotating shaft 4 in conjunction with an adjusting rod 8 and a limiting plate 12. This solves the problem of damage caused by frequent extension and retraction of the motor. The new type of gripper 5 has a long service life, simple structure, and is easy to implement, which greatly ensures the continuity of production. Example 2

[0022] As a preferred embodiment of this utility model, this embodiment modifies the adjusting rod 8 based on Embodiment 1, specifically as follows:

[0023] In this embodiment, the adjusting rod 8 is a threaded rod that passes through the mounting plate 7 and is mounted on the mounting plate 7 by two nuts 9.

[0024] The height of the gripper 5 can be adjusted by adjusting the height of the threaded rod, thus making the device suitable for rubber discs 13 of different heights. Example 3

[0025] As a preferred embodiment of this utility model, this embodiment designs the structure of the lifting frame 3 based on Embodiment 1, specifically as follows:

[0026] In this embodiment, the lifting frame 3 is square. Both the front and rear plates are provided with multiple pairs of guide wheels 10 for clamping the guide rail 2. Both plates are provided with multiple support wheels 11 that roll in contact with the guide rail 2 in the middle. The support wheels 11 are arranged perpendicularly to the guide wheels 10. This arrangement can improve the stability of the lifting frame 3 when it is raised or lowered.

[0027] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
