The shape and size of the pick-up channel are matched with the iron pick; an open storage box 3.6 is movably placed on the frame 1 between the two frame plates 3.1 to collect the meat strips after pick-up.

[0041] Working principle:

[0042] Place the two ends of the iron rod of the grilled meat strips at the bottom of the two V-shaped grooves 3.8. At the same time, the iron rod is clamped in the lower block slide groove 3.11 on the lower block 3.7, and the two ends of the iron rod protrude from the relatively outer sides of the two frame plates 3.1. At this time, the lifting cylinder 3.2 extends a certain stroke, and the upper block 3.3 moves downward, so that the bottom surface of the upper block protrusion 3.10 is tightly fitted with the bottom of the lower block groove 3.9, and the iron rod is clamped in the rod extraction channel.

[0046] Working principle:

[0047] According to the working principle of Example 1, when placed at the bottom of the two V-shaped grooves 3.8, since the two ends of the iron rod protrude from the relatively outer sides of the two frame plates 3.1, and at this time the iron rod intersects with the irradiation line of the infrared radiation switch 4, the part of the iron rod protruding from the outer side of the frame plate 3.1 close to the horizontal oil cylinder 3.4 will make the infrared radiation switch 4 unable to be turned on, and then the controller 5 determines that the iron rod is in place; at this time, the controller 5 controls the lifting cylinder 3.2 to extend a certain stroke, and the upper block 3.3 moves downward, so that the bottom surface of the upper block protrusion 3.10 is tightly fitted with the bottom of the groove 3.9 of the lower block, and the iron rod is stuck in the rod extraction channel; after a time interval of 2s, the controller 5 controls the horizontal oil cylinder 3.4 ... upper block protrusion 3.10 is tightly fitted with the bottom of the groove 3.9 of the lower block, and the iron rod is stuck in the rod extraction channel. After a fixed stroke, the electric clamp 3.5 is extended to the end of the iron rod; after a time interval of 2s, the controller 5 controls the electric clamp 3.5 to close so that it clamps the iron rod tightly, and after a time interval of 2s, the controller 5 controls the horizontal cylinder 3.4 to contract, so that the iron rod slides out of the rod extraction channel under the clamping action of the electric clamp 3.5. At the same time, the meat strips are completely separated from the rod extraction channel under the blocking action of the upper block 3.3 and the lower block 3.7, and the meat strips fall into the storage box 3.6 below; after a time interval of 2s, the controller 5 controls the lifting cylinder 3.2 to contract and reset, thus completing the rod extraction work of the meat strip skewers; this reciprocating process can be repeated for multiple meat strip skewers.

[0048] In this embodiment, the controller 5 adopts a conventional chip, and the controller 5 is installed in the rack 1. The infrared beam switch 4 is small in size, easy to install, and sensitive induction.

[0051] The two chain conveyors 2.3 are respectively arranged in one-to-one correspondence with the two frame plates 3.1, and the two chain conveyors 2.3 are respectively arranged on the relatively outer sides of the two frame plates 3.1, and the discharge ends of the chain conveyors 2.3 are placed above the notches of the V-shaped grooves 3.8.

[0052] The conveying mechanism 2 also includes a driving motor 2.1 and a transmission shaft 2.2; the driving motor 2.1 is fixed on the frame 1, and the output shaft of the driving motor 2.1 is connected to the transmission shaft 2.2, and the transmission shaft 2.2 is respectively connected to the driving sprockets 2.3.1 of the two chain conveyors 2.3, and the height of the transmission shaft 2.2 is lower than the height of the two driving sprockets 2.3.1, ensuring that the transmission shaft 2.2 will not affect the passage of the meat skewers in the meat skewers conveying channel.

[0053] A plurality of stoppers 2.3.3 are evenly and fixedly arranged on the chains 2.3.2 of the two chain conveyors 2.3. The plurality of stoppers 2.3.3 are radiated outwards, and the positions of the stoppers 2.3.3 on the two chains 2.3.2 are symmetrical.

The end of the guide plate 2.5 close to the feeding end of the conveying mechanism 2 is inclined toward the relatively outer sides of the two chain conveyors 2.3, which can correct the position of the iron rod on the chain 2.3.2 so that the two ends of the iron rod protrude from the two chains 2.3.2 by a considerable distance, thereby preventing one end of the iron rod from falling off during the transmission process and failing to pull out the rod normally.

[0056] Working principle:

[0057] Place the two ends of the iron rod of the baked barbecue strips on the two unloading chutes 2.4. Under the action of gravity, the iron rod moves to the two chains 2.3.2 at the feeding end of the conveying mechanism 2. As the chain 2.3.2 moves forward, the guide plate 2.5 can correct the position of the iron rod on the chain 2.3.2. The stopper 2.3.3 on it can also prevent the iron rod from sliding on the chain 2.3.2, causing the two ends of the iron rod to move forward asynchronously, and finally causing the iron rod to fall between the two chains 2.3.2.

[0058] When the iron rod is conveyed to the discharge end of the conveying mechanism 2, under the action of the V-shaped groove 3.8 on the frame plate 3.1, the iron rod slides along the groove edge of the V-shaped groove 3.8 to the bottom of the V-shaped groove 3.8, and then according to the working principle of Example 1, the meat skewers can be pulled out of the rod.

[0061] The two chain conveyors 2.3 are respectively arranged in one-to-one correspondence with the two frame plates 3.1, and the two chain conveyors 2.3 are respectively arranged on the relatively outer sides of the two frame plates 3.1, and the discharge ends of the chain conveyors 2.3 are placed above the notches of the V-shaped grooves 3.8.

[0062] The conveying mechanism 2 also includes a driving motor 2.1 and a transmission shaft 2.2; the driving motor 2.1 is fixed on the frame 1, and the output shaft of the driving motor 2.1 is connected to the transmission shaft 2.2, and the transmission shaft 2.2 is respectively connected to the driving sprockets 2.3.1 of the two chain conveyors 2.3, and the height of the transmission shaft 2.2 is lower than the height of the two driving sprockets 2.3.1, ensuring that the transmission shaft 2.2 will not affect the passage of the meat skewers in the meat skewers conveying channel.

[0063] A plurality of stoppers 2.3.3 are evenly and fixedly arranged on the chains 2.3.2 of the two chain conveyors 2.3. The plurality of stoppers 2.3.3 are radiated outwards, and the positions of the stoppers 2.3.3 on the two chains 2.3.2 are symmetrical.

[0065] A vertically arranged guide plate 2.5 is symmetrically and fixedly arranged on the frame 1 outside the two chain conveyors 2.3, and the plate surface of the guide plate 2.5 is parallel to the plate surface of the frame plate 3.1. The end of the guide plate 2.5 close to the feeding end of the conveying mechanism 2 is inclined toward the relatively outer sides of the two chain conveyors 2.3, which can correct the position of the iron rod on the chain 2.3.2 so that the two ends of the iron rod protrude from the two chains 2.3.2 by a considerable distance, thereby preventing one end of the iron rod from falling off during the transmission process and failing to pull out the rod normally.

[0066] In addition, the present embodiment further comprises an infrared beam switch 4 and a controller 5. The infrared beam switch 4 is fixedly arranged on the outer plate surface of the frame plate 3.1 close to the horizontal oil cylinder 3.4.

[0068] Working principle:

[0069] Place the two ends of the iron rod of the baked barbecue strips on the two unloading chutes 2.4. Under the action of gravity, the iron rod moves to the two chains 2.3.2 at the feeding end of the conveying mechanism 2. As the chain 2.3.2 moves forward, the guide plate 2.5 can correct the position of the iron rod on the chain 2.3.2. The stopper 2.3.3 on it can also prevent the iron rod from sliding on the chain 2.3.2, causing the two ends of the iron rod to move forward asynchronously, and finally causing the iron rod to fall between the two chains 2.3.2.

[0070] When the iron rod is conveyed to the discharge end of the conveying mechanism 2, under the action of the V-groove 3.8 on the frame plate 3.1, the iron rod slides along the groove edge of the V-groove 3.8 to the bottom of the V-groove 3.8, and at the same time, the iron rod is stuck in the lower block slide groove 3.11 on the lower block 3.7, and the two ends of the iron rod protrude from the relatively outer sides of the two frame plates 3.1; at this time, the iron rod intersects with the irradiation line of the infrared beam switch 4, so the part of the iron rod protruding from the outer side of the frame plate 3.1 close to the horizontal cylinder 3.4 will make the infrared beam switch 4 unable to be turned on, and then the controller 5 determines that the iron rod is in place; at this time, the controller 5 controls the lifting cylinder 3.2 to extend a certain stroke, and the upper block 3.3 moves downward, so that the bottom surface of the upper block protrusion 3.10 is tightly fitted with the bottom of the groove 3.9 of the lower block groove, and the iron rod is stuck in the rod extraction channel. ; After a time interval of 2s, the controller 5 controls the horizontal cylinder 3.4 to extend a certain stroke, so that the electric clamp 3.5 extends to the end of the iron rod; after another time interval of 2s, the controller 5 controls the closing of the electric clamp 3.5 to clamp the iron rod tightly, and after another time interval of 2s, the controller 5 controls the horizontal cylinder 3.4 to contract, so that the iron rod slides out of the rod pulling channel under the clamping action of the electric clamp 3.5. At the same time, the meat strips are completely separated from the rod pulling channel under the blocking action of the upper block 3.3 and the lower block 3.7, and the meat strips fall into the storage box 3.6 below; after another time interval of 2s, the controller 5 controls the lifting cylinder 3.2 to contract and reset, and the rod pulling work of the meat strip skewers is completed once; this reciprocating process can be repeated for multiple meat strip skewers.

[0071] In this embodiment, the controller 5 adopts a conventional chip, and the controller 5 is installed in the rack 1. The infrared beam switch 4 is small in size, easy to install, and sensitive induction.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
