Description

Technical Field

[0001] The utility model relates to the technical field of transmission equipment, in particular to a turntable for preventing backflow of the track of a flexible chain conveyor. Background Technique

[0002] In recent years, with the popularization of the application of lithium batteries, a large number of lithium batteries are used in various industries. Therefore, there are certain requirements for the production efficiency of lithium-ion batteries. Usually, the form of a flexible chain conveyor plus a drag cup is used to transport the battery cores that have been assembled but have not undergone processes such as liquid injection, baking, and formation. The battery cores that do not pass various inspection standards will be pushed to the track for re-inspection. Then, the drag cup will return to the main track in advance along with the re-inspection channel. At present, people use a turntable to turn the drag cup 180° from the forward track to the reverse track. This method has a simple structure and low cost. However, the following problems will occur when using this structure:

[0003] 1. When the blocking pin of the blocking cylinder extends, the drag cup will stay on the reverse track. When the number of drag cups is large enough, it is easy to block the Y-shaped angle formed by the reverse track and the turntable outlet, and the drag cup still cannot flow by itself after the blocking pin retracts.

[0004] 2. When the drag cup on the forward track enters the turntable, there will also be a drag cup on the reverse track being transported towards the turntable outlet. The two drag cups will meet and be squeezed at the turntable outlet, so there is also a certain probability of forming a blockage. When the number of drag cups is large enough, the probability of blockage formed in this way is also large enough. Content of the Utility Model

[0005] The purpose of the utility model is to provide a turntable for preventing backflow of the track of a flexible chain conveyor to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1 , in the embodiment of the present invention, a turntable for preventing the reverse flow of the track of a flexible chain conveyor includes a bracket 3 and a forward track 7 and a reverse track 12 located on the bracket 3. The forward track 7 and the reverse track 12 are arranged in parallel. Both the forward track 7 and the reverse track 12 are drag chain structures. A diversion frame 2 is provided between the forward track 7 and the reverse track 12. Below the diversion frame 2, there is an anti - reverse rotation turntable 4. The anti - reverse rotation turntable 4 is located between the forward track 7 and the reverse track 12. At the lower end of the anti - reverse rotation turntable 4, there is a motor 5 for driving the anti - reverse rotation turntable 4 to rotate.

[0025] The anti - reverse rotation turntable 4 includes a smooth turntable 10. The upper end of the smooth turntable 10 is flush with the upper end faces of the forward track 7 and the reverse track 12. At the peripheral part of the upper end of the anti - reverse rotation turntable 4, there is a protruding bevel angle 9. The protruding bevel angle 9 is located at the edge of the anti - reverse rotation turntable 4. The inclination direction of the protruding bevel angle 9 is the same as the rotation direction of the anti - reverse rotation turntable 4. In this embodiment, the protruding bevel angle 9 is fixedly connected to the upper end of the smooth turntable 10. At the lower end of the protruding bevel angle 9, there is a screw hole 11 for fixedly connecting with the smooth turntable 10. There are six protruding bevel angles 9, and the six protruding bevel angles 9 are arranged peripherally.

[0026] A drag cup 1 is provided on the forward track 7 and / or the reverse track 12. The radius of the anti - reverse rotation turntable 4 is not less than the sum of the diameter of the drag cup 1 and the radial length of the protruding bevel angle 9. The bottom of the drag cup 1 is provided with a wear - resistant material layer, and a counterweight is provided at the bottom of the drag cup 1. The diversion frame 2 is located in the middle of the drag cup 1 in the height direction. A blocking part is provided on the reverse track 12. The blocking part includes a stop pin 8 and a blocking cylinder 6 for driving the stop pin 8 to move. The horizontal height of the stop pin is placed at the center - of - gravity position of the drag cup to prevent the drag cup from tipping over.

[0027] Embodiment 1

[0028] The drag cup 1 on the forward track 7 is driven by the drag chain and reaches the anti-reverse turntable 4 along the guide frame 2. The anti-reverse turntable 4 is driven to rotate by the motor 5, and the drag cup 1 is sent to the drag chain on the reverse track 12. The blocking cylinder 6 receives the instruction of the next process, the blocking pin 8 extends out, and multiple drag cups 1 are stacked on the reverse track 12 until they are pushed at the outlet of the anti-reverse turntable 4. At this time, the drag chain is still running, and the drag cup 1 will have a reverse potential energy due to the friction of the drag chain. The drag cup itself is cylindrical. If the tangent is not parallel to the moving direction, it will be deviated, and it is easy to be squeezed into the turntable at the outlet of the anti-reverse turntable 4. At this time, the sudden slope angle 9 has a vertical section for the drag cup on the reverse track. In this way, the drag cup 1 on the reverse track wants to enter the turntable 4 and will be blocked by the sudden slope angle 9. The drag cup 1 stays on the turntable 4, and the turntable 4 and the bottom of the drag cup 1 friction at the plane until the blocking pin 8 retracts. After the track is released, the drag cup 1 normally flows into the next process.

[0029] Embodiment 1

[0030] The drag cup 1 on the forward track 7 is driven by the drag chain and reaches the anti-reverse turntable 4 along the guide frame 2. The anti-reverse turntable 4 is driven to rotate by the motor 5, and the drag cup 1 is sent to the drag chain on the reverse track 12. At this time, the drag cup 1 of the previous process on the reverse track 12 will pass through the outlet of the anti-reverse turntable 4 along the track. If the drag cup 1 on the turntable 4 and the drag cup 1 on the reverse track 12 reach the outlet at the same time, the two drag cups 1 are easily stuck by the guide frame at this time. At this time, when the turntable 4 rotates, the sudden slope angle 9 has a component force facing the center of the circle for the drag cup 1, which will separate the two stuck drag cups 1. The drag cup 1 on the reverse track continues to flow into the next process, and the drag cup 1 on the turntable 4 continues to look for the next opportunity to enter the reverse track after staying for a moment, and cycles in turn.
