[0003] During the production process of covered electrodes, due to limited space in the covered electrode manufacturing production line, the covered electrode transportation process inevitably requires turning. The existing covered electrode turning and conveying mechanism usually uses an L-shaped chain plate connected to a covered electrode bearing support plate to achieve covered electrode turning. However, during the use of this mechanism, due to the bending of the chain, the chain inevitably tends to become loose. Also, when the surface temperature of the covered electrode is around 80 degrees Celsius, the chain expands when heated, and it is also prone to loosening and causing chain jamming faults, affecting the production of covered electrodes.

[0004] Therefore, the existing technology needs to be improved. Summary of the Utility Model

[0028] Embodiment

[0029] This embodiment provides a welding rod chain type turning machine, as Figure 1 - Figure 2 shown, and the specific structure is described as follows.

[0030] Please refer to Figure 1 shown. The welding rod chain type turning machine of this embodiment mainly consists of a frame 1, a conveying mechanism 2, a feeding transition mechanism 3, a discharging transition mechanism 4, a aligning mechanism 5, a driving mechanism, and a tensioning mechanism 7. Among them, the frame 1 is used to provide an installation position for other components; the feeding transition mechanism 3 is used to transport the welding rods of the front-end conveying line 6 to the conveying mechanism 2; the conveying mechanism 2 is used to transport the welding rods from the feeding end to the discharging end to complete the turning transportation; the discharging transition mechanism 4 is used to transport the welding rods of the conveying mechanism 2 to the rear-end conveying line. The driving mechanism is used to drive the conveying mechanism 2 to work. The aligning mechanism 5 is used to make the heads and tails of the welding rods on the conveying mechanism 2 neat. The tensioning mechanism 7 is used to keep the turning chain 201 in a tensioned or taut state at all times to ensure stable transportation.

[0031] Furthermore, in combination with Figure 1As shown, the frame 1 is composed of profiles and stainless steel plates commonly used in the turning machine assembly line in the prior art, and has the advantages of easy assembly and low cost. At the same time, support legs are installed at the bottom of the frame 1 to support it on the ground. A base is also installed at the bottom of the support legs to enhance the stability of the frame 1.

[0032] In some embodiments of this embodiment, the conveying mechanism 2 is mainly composed of two parts: a turning chain 201 and a chain plate track 202. The turning chain 201 and the chain plate track 202 are connected to play the role of conveying welding rods. At the same time, a plurality of driving sprockets are installed at appropriate positions on the frame 1 (for example, one is installed at intervals along the conveying direction). The turning chain 201 is sleeved on the driving sprockets, and the driving sprockets are used to support the movement of the turning chain 201.

[0033] Furthermore, the driving mechanism uses a variable-frequency speed-regulating motor in the prior art. In this embodiment, two variable-frequency speed-regulating motors are installed as dual power to drive the inner and outer turning chains 201 respectively, ensuring that the angular velocities of the front and rear ends of the welding rod are the same during the turning process, so that the welding rod does not deflect or get disordered, and the conveying effect is better. The driving mechanism drives a driving sprocket at the end through a belt drive. This driving sprocket serves as the driving wheel, and the other driving sprockets serve as driven wheels. The driving mechanism is controlled by the PLC electric control system to realize the control of the conveying start and stop, matching the variable-frequency speed regulation, and matching the speeds of the front-end conveying line 6 and the rear-end conveying line.

[0034] Combined Figure 1 and Figure 2 As shown, the tensioning mechanism 7 is mainly composed of two parts: an elastic member 701 and a conveying tensioning sprocket 702. Among them, the elastic member 701 can deform along the vertical direction. The elastic member 701 includes four parts: a sleeve 7011, a spring 7012, a mounting head 7013, and a guide rod 7014. The sleeve 7011 is fixed on the frame 1 by means of screw connection. The opening of the sleeve 7011 is at the top end. The guide rod 7014 and the spring 7012 are both inserted into the interior of the sleeve 7011. The guide rod 7014 can move vertically along the sleeve 7011, and the spring 7012 is sleeved on the guide rod 7014.

[0035] Furthermore, as Figure 2 shown, the mounting head 7013 is welded and fixed to the top end of the guide rod 7014. A prolonging rod is connected to the right end face of the guide rod 7014. A bearing 7016 is installed on this prolonging rod. The conveying tensioning sprocket 702 is sleeved on the bearing 7016 and fixedly connected to the bearing 7016. Supported by the bearing 7016, the conveying tensioning sprocket 702 rotates more smoothly.

[0036] Furthermore, a push rod 7015 is inserted into the bottom of the sleeve 7011 and is threadedly connected to the sleeve 7011. After the push rod 7015 rotates, the push rod 7015 can be raised or lowered. The top of the push rod 7015 abuts against the bottom of the guide rod 7014 and the spring 7012.

[0037] When in use, the conveying tensioning sprocket 702 abuts against the bottom turning chain 201, without affecting the transportation of the upper turning chain 201. The spring 7012 is in a compressed state, pushing the installation head 7013 and the conveying tensioning sprocket 702 to tension or tighten the turning chain 201, so as to prevent the turning chain 201 from loosening and derailing. At the same time, the spring 7012 has a shock-absorbing effect. Even if the turning chain 201 has a small amplitude of jumping during the working process, the spring 7012 can still play a role to ensure that the turning chain 201 is always tight. At the same time, the tension of the turning chain 201 can be adjusted by the push rod 7015. After the push rod 7015 rises, the spring 7012 is compressed more severely, and then the turning chain 201 is tightened. After the push rod 7015 rises, the spring 7012 is compressed less, and then the tension of the turning chain 201 is reduced, which is convenient for the staff to adjust.

[0038] Combination Figure 1 As shown, the aligning mechanism 5 is a long metal strip, both ends of the aligning mechanism 5 are curved surfaces, a long hole is opened in the center of the aligning mechanism 5, and screws are inserted into the long hole to be fixedly connected to the frame 1. The aligning mechanism 5 is located on both sides of the frame 1. After loosening the screws, the angle of the aligning mechanism 5 and the distance to the chain plate support rail 202 can be adjusted to align the ends of the welding rods during transportation.

[0039] In some implementations of this embodiment, Figure 1 As shown, the structures and uses of the feed transition mechanism 3 and the discharge transition mechanism 4 are similar. The right end of the feed transition mechanism 3 is connected to the front-end conveying line 6, and the left end is connected to the conveying mechanism 2. The upper end of the discharge transition mechanism 4 is connected to the conveying mechanism 2, and the lower end is connected to the rear-end conveying line. The feed transition mechanism 3 transports the welding rods of the front-end conveying line 6 to the conveying mechanism 2, and the discharge transition mechanism 4 transports the welding rods of the conveying mechanism 2 to the rear-end conveying line.

[0040] Furthermore, the feed transition mechanism 3 includes a feed driving sprocket 301, a feed driven sprocket 302, a feed tensioning sprocket 303 and a feed conveying chain. The feed driving sprocket 301 is installed on the front conveying line 6, and the feed driven sprocket 302 and the feed tensioning sprocket 303 are installed on the frame 1. The feed driving sprocket 301 is driven by a motor. The feed conveying chain is sleeved on the feed driving sprocket 301 and the feed driven sprocket 302. The feed tensioning sprocket 303 supports the feed conveying chain, thereby tensioning the feed conveying chain.

[0041] Furthermore, the discharging transition mechanism 4 includes a discharging driving sprocket 401, a discharging driven sprocket 402, a discharging tensioning sprocket 403 and a discharging conveyor chain. The discharging driving sprocket 401 is installed on the rear conveying line, and the discharging driven sprocket 402 and the discharging tensioning sprocket 403 are installed on the frame 1. The discharging driving sprocket 401 is driven by a motor. The discharging conveyor chain is sleeved on the discharging driving sprocket 401 and the discharging driven sprocket 402. The discharging tensioning sprocket 403 supports the discharging conveyor chain, thereby tensioning the discharging conveyor chain.

[0042] The working principle of the electrode chain type turning machine of the present utility model is as follows:

[0043] The feeding transition mechanism 3 transports the electrodes on the front conveying line 6 to the conveying mechanism 2. The conveying mechanism 2 transports the electrodes from the feeding end to the discharging end to complete the turning transportation. Then, the discharging transition mechanism 4 transports the electrodes of the conveying mechanism 2 to the rear conveying line. The driving mechanism drives the turning chain 201 and the chain plate track 202 of the conveying mechanism 2 to move, playing a role in transporting the electrodes. The aligning mechanism 5 ensures that the head and tail are aligned during the transportation. The turning chain 201 of the conveying mechanism 2 is abutted by the conveying tensioning sprocket 702 of the tensioning mechanism 7 to ensure that the turning chain 201 is always in a taut state, reducing the occurrence of chain derailment and chain jamming. And the elastic member 701 can stretch within a certain range, and can thus cope with the loosening of the turning chain 201 within a certain range, ensuring that the conveying tensioning sprocket 702 always keeps the turning chain 201 tensioned or taut, and the use effect is better.
