Description

Technical Field

[0001] This utility model belongs to the technical field of automated food processing equipment, specifically, it relates to an automatic skewer feeding and stringing mechanism. Background Technology

[0002] In the food processing industry, especially in the production of grilled and fried skewers, the supply of skewers and the skewering of materials currently rely heavily on manual operation. Manual skewering suffers from low efficiency, high labor intensity, and inconsistent product quality, making it difficult to meet the demands of large-scale production. Although some automated skewering equipment exists, it generally suffers from technical defects such as unstable skewer gripping, unreliable fixing, and easy material deviation during delivery.

[0003] Traditional skewer clamping structures, due to their unreasonable design, cannot effectively fix bent or misaligned skewers, resulting in frequent instances of gaps in the skewers. Furthermore, insufficient rigidity or mismatched shape of the skewer-pulling components prevents the material from being smoothly pushed to the designated position during skewering, and may even cause mechanical interference, severely affecting the operating efficiency and skewering success rate of the equipment.

[0029] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention.

[0030] like Figure 1-5 As shown, this utility model provides an automatic label feeding and stringing mechanism, including a mechanism frame, a transfer device, a clamping device, and a label dispensing device. The transfer device is fixedly installed on the bottom right side of the mechanism frame, the clamping device is fixedly installed on the top left side of the mechanism frame, and the label dispensing device is located above the clamping device and is fixedly connected to the mechanism frame.

[0031] The transfer device includes a lifting electric cylinder 13, a skewer-feeding steering motor 14, a two-finger cylinder connecting plate 15, two-finger cylinders 16, a conveyor belt 18, and a drive motor 19. The conveyor belt 18 is mounted on multiple conveying rollers on the mechanism frame. The drive motor 19 is fixedly installed on the mechanism frame. The output shaft of the drive motor 19 rotates synchronously with the drive roller in the conveying rollers through a coupling, so that the conveyor belt 18 can drive the material basket 17 to complete the conveying. The lifting electric cylinder 13 is fixedly installed in the middle of the rear side plate of the mechanism frame. The skewer-feeding steering motor 14 is fixedly installed at the output rod end of the lifting electric cylinder 13. The two-finger cylinder connecting plate 15 is fixedly installed on the front output shaft of the skewer-feeding steering motor 14. Two two-finger cylinders 16 are arranged on the inner side of the two-finger cylinder connecting plate 15. The two-finger cylinders 16 are responsible for gripping the skewer 3 to prevent the skewer 3 from becoming unbalanced or falling due to the gripping position not being in the middle part of the skewer 3.

[0032] The tack-clamping device includes a first tack-clamping cylinder 1, a first front tack-clamping component 2, a second tack-clamping cylinder 5, a second front tack-clamping component 6, a second rear tack-clamping component 9, a first rear tack-clamping component 10, and a third tack-clamping cylinder 11. The first tack-clamping cylinder 1 is fixedly installed on the left side of the front frame of the mechanism frame, and the second tack-clamping cylinder 5 is fixedly installed on the left side of the rear frame of the mechanism frame. Frame plates are fixedly installed in the middle of the front and rear side plates of the mechanism frame. The third tack-clamping cylinder 11 and the second rear tack-clamping component 9 are supported and fixed by the two frame plates. The third tack-clamping cylinder 11 is fixedly installed on the frame plate on the front side of the mechanism frame. The first front tack-clamping component 2 is fixedly installed at the output end of the first tack-clamping cylinder 1, the second front tack-clamping component 6 is fixedly installed at the output end of the second tack-clamping cylinder 5, and the first rear tack-clamping component 10 is fixedly installed at the output end of the third tack-clamping cylinder 11. The first rear tack-clamping component 10 and the second rear tack-clamping component 9 are correspondingly arranged.

[0033] Two notched fixing plates 403 are installed at intervals on the rear side of the top plate of the output end of the first clamping cylinder 1. A stop plate is fixedly installed on the middle of the front side of the top plate of the output end of the second clamping cylinder 5, forming a T-shape with the top plate of the output end of the second clamping cylinder 5. The first front clamping piece 2 and the second front clamping piece 6 clamp correspondingly, so that the stick 3 achieves force balance during clamping. The fixing plates 403 and the stop plate are respectively opened in the middle of the side close to each other, and the same semi-circular fixing holes 401 with the same diameter as the stick 3 are opened. When the first clamping cylinder 1 and the second clamping cylinder 5 are activated, so that the first front clamping piece 2 and the second front clamping piece 6 are close to each other, most of the force generated by the cylinder push can be transferred to the stick 3, increasing its fixing force. Both the fixed plate 403 and the bottom of the abutment are provided with sloping protrusions 402. The protrusions 402 guide the skewer 3 to slide along the slope of the protrusions 402 into the semi-circular fixing hole 401 when the first front clamp skewer 2 and the second front clamp skewer 6 approach each other. This prevents the skewer 3 from being misaligned during the operation of the transfer device, which could result in the first front clamp skewer 2 and the second front clamp skewer 6 being misaligned. Even if the skewer 3 is bent due to long-term use, as long as the degree of bending is not lower than the bottom of 402, the skewer 3 can still be guided into the semi-circular fixing hole 401. The shape of the first rear clamp skewer 10 is consistent with that of the first front clamp skewer 2, and the shape of the second rear clamp skewer 9 is consistent with that of the abutment.

[0034] The tag-picking device includes a tag-picking rod 4, a tag-picking cylinder adapter plate 7, a tag-picking cylinder 8, and a tag-picking electric cylinder 12. The tag-picking electric cylinder 12 is fixedly installed on the top of the rear side plate of the mechanism frame. The tag-picking cylinder adapter plate 7 is installed on the output end of the tag-picking electric cylinder 12. The tag-picking cylinder 8 is fixedly installed on the tag-picking cylinder adapter plate 7. The tag-picking rod 4 is fixedly connected to the output end of the tag-picking cylinder 8.

[0035] The lower output shaft of the tack-dispensing cylinder 8 is fixedly connected to one end of the tack-dispensing rod 4. An extension is fixedly installed at the bottom of the other end of the tack-dispensing rod 4. Triangular reinforcing plates 501 are installed between the tack-dispensing cylinder 8, the extension, and the tack-dispensing rod 4 to prevent shaking and failure to press the tack 3 tightly during use. An arc surface 502 with the same diameter as the tack 3 is opened at the bottom of the extension.

[0036] Working principle:

[0037] In use, the material basket 17 containing the skewers 3 is first placed on the conveyor belt 18. The drive motor 19 is started, and the drive roller is rotated through the coupling, thereby driving the conveyor belt 18 to transport the material basket 17 to the bottom of the transfer device. When the material basket 17 is in place, the drive motor 19 stops, the lifting cylinder 13 drives the two-finger cylinder 16 to descend, the two-finger cylinder 16 closes to grab the skewers 3, the lifting cylinder 13 rises and cooperates with the skewer supply steering motor 14 to rotate the skewers 3 180° and lift them to the bottom of the skewer clamping mechanism, the two two-finger cylinders 16 release, and the skewer 3 is handed over to the upper skewer clamping cylinder. At this time, the first skewer clamping cylinder 1, the second skewer clamping cylinder 5, and the third skewer clamping cylinder 16 are in operation. 1. The optimized first front clamp 2, second front clamp 6, second rear clamp 9, and first rear clamp 10 are used to close and fix the skewer 3. When the material is passed to the front of the skewer 3, the skewer-pulling electric cylinder 12 starts to move, driving the skewer-pulling rod 4 to the front of the skewer 3. Then the skewer-pulling cylinder 8 opens, causing the skewer-pulling rod 4 to press down and fit tightly against the skewer 3. At this time, the skewer-pulling electric cylinder 12 moves to the rear of the skewer 3. In this way, the material is passed to the rear of the skewer 3 by the skewer-pulling rod 4. Finally, the skewer-pulling cylinder 8 closes, lifting the skewer-pulling rod 4 and making it leave the surface of the skewer 3. The whole process is precisely controlled by the control system to control the timing and parameters of each component, so as to achieve stable and efficient automatic skewer feeding and stringing operation.
