Description

Technical Field

[0001] This utility model relates to the field of food equipment technology, specifically to a multi-material adaptive threading device. Background Technology

[0002] Barbecue, as an extremely common food, still faces many technical challenges in its core skewering process. Traditional hand skewering relies heavily on the operator's experience and physical strength, making it time-consuming and labor-intensive.

[0003] As a result, skewering equipment for barbecue has appeared on the market. However, the skewering equipment currently on the market generally has a single function and can only process uniformly sized block-shaped ingredients. It cannot be used for skewering large quantities of different kinds of ingredients.

[0004] Patent document CN117581894A discloses a skewering assembly for pork belly, including a frame and a conveyor chain. The conveyor chain is installed inside the frame, and several mounting bases are evenly spaced on the outer side of the conveyor chain. A meat-holding seat is detachably mounted on each mounting base. The meat-holding seat has a meat groove for placing pork belly and a skewer groove for threading. A support is mounted on the frame, and a first pneumatic cylinder is mounted on the top side of the support. A pressing seat adapted to the meat-holding seat is installed at the telescopic end of the first pneumatic cylinder. When the skewer-feeding block moves to push the skewers, a third motor drives a threaded rod to rotate, causing two threadedly connected limit seats to move. This adjusts the distance between the two limit pressure rollers, ensuring the skewers move between the two limit pressure rollers, thus limiting the movement of the skewers and preventing them from deviating. This equipment is only suitable for skewering pork belly, and its function is relatively limited, unable to adapt to skewering of various materials. Utility Model Content

[0069] 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. These all fall within the protection scope of the present invention.

[0070] This utility model discloses a multi-material adaptive skewering device. By arranging the materials into a single row, and coordinating the transport of the materials with two rows of conveying rollers and the skewering action of the clamping module, it can realize the complete replacement of manual labor from raw material feeding, skewer supply and finished product transportation. It is suitable for skewering large batches of materials. Furthermore, by installing the conveying rollers at the bottom of two conveying adjustment plates, the distance between the two rows of conveying rollers can be flexibly adjusted, which can ensure that the materials are transported smoothly to the skewering area without damaging the materials themselves. It is suitable for skewering different types of food.

[0071] According to the multi-material adaptive threading device provided by this utility model, such as Figure 1 As shown, it includes a feeding device, a stringing device, and a string feeding device. The feeding device is used to convey rows of materials to the stringing device, and the string feeding device is used to feed iron skewers to the stringing device.

[0072] In a preferred embodiment, the feeding device includes a material frame 11, a feeding gripper 12, a three-axis linear module 13, a conveyor belt 14, and a vibrating distribution line 15. The feeding gripper 12 is mounted on the Z-axis motion module of the three-axis linear module 13 and is located above the material frame 11. It is used to grip the material in the material frame and place it on the conveyor belt 14. The conveyor belt 14 is mounted on one side of the three-axis linear module 13 and is used to receive the material gripped by the feeding gripper 12 and convey it to the vibrating distribution line 15. The inlet end of the vibrating distribution line 15 is connected to the outlet end of the conveyor belt 14, and the outlet end of the vibrating distribution line 15 is connected to the inlet end of the labeling platform 25. The vibrating distribution line 15 is used to distribute the material and form a single row of material.

[0073] In more preferred embodiments, the vibrating material distribution line 15 includes a conveying trough, a diverting plate, and a vibrator; the inlet end of the conveying trough is connected to the outlet end of the conveying belt 14, and the outlet end of the conveying trough is connected to the inlet end of the labeling platform 25, with the inlet end of the conveying trough being higher than the outlet end; there are multiple diverting plates, which are sequentially installed in the conveying trough along the material conveying direction, and the diverting plates are inclined towards the material conveying direction; one end of each diverting plate is connected to the inner wall of one side of the conveying trough, and the other end of the diverting plate has a gap between it and the inner wall of the other side of the conveying trough for material to pass through; the vibrator acts on the outside of the conveying trough to drive the material through the gap between the diverting plate and the inner wall of the conveying trough, forming a single row of material. Since the material grabbed by the feeding claw 12 is an irregular pile, it is necessary to use the diversion and vibration of the vibrating material distribution line 15 with diverting plates to organize the material into a single row.

[0074] Furthermore, such as Figure 5 As shown, the feeding gripper 12 includes a linear cylinder 43, a movable connecting rod 42, and multiple arc-shaped grippers 41 arranged circumferentially. In the closed state, there is a gap between the multiple arc-shaped grippers 41. The cylinder body of the linear cylinder 43 is fixedly mounted on the Z-axis motion module, and the arc-shaped grippers 41 are mounted on the bottom of the linear cylinder 43 through the movable connecting rod 42. The linear cylinder 43 is used to open and close the arc-shaped grippers 41 by extending and retracting. During installation, a certain gap is left between each arc-shaped gripper 41 to ensure that the gripping of the material is not too tight and damages the material. Driven by the three-axis linear module 13, the feeding gripper 12 can move linearly along the X-axis, Y-axis, and Z-axis to grab the material inside the material frame 11 onto the conveyor belt 14.

[0075] like Figure 2 As shown, the label stringing device includes a fixed top plate 23, roller adjustment plates 24, a label stringing platform 25, conveying rollers 26, and a conveying drive motor 28. The inlet end of the label stringing platform 25 is connected to the outlet end of the feeding device. The fixed top plate 23 is fixedly installed on the top of the label stringing platform 25. Two roller adjustment plates 24 are installed side by side at the bottom of the fixed top plate 23. There are multiple conveying rollers 26 arranged in two rows. The two rows of conveying rollers 26 are respectively installed at the bottom of the two roller adjustment plates 24. The roller adjustment plates 24 are used to adjust the distance between the two rows of conveying rollers 26. The conveying drive motor 28 is installed on the fixed top plate 23 and is connected to the two rows of conveying rollers 26 for transmission. It is used to control the rotation of the two rows of conveying rollers 26. The two rows of conveying rollers 26 rotate in opposite directions to drive the material on the label stringing platform 25 toward the outlet end of the label stringing platform 25.

[0076] In a preferred embodiment, the tagging device further includes a tension block 27 and a feeding timing belt 29; the feeding timing belt 29 is sleeved on the outside of the feeding drive motor 28 and the two rows of feeding rollers 26, and is connected to the two rows of feeding rollers 26 in a transmission manner; the tension block 27 is fixedly installed in the slot on the edge of the fixed top plate 23 by fixing bolts, and the tension block 27 is set inside the feeding timing belt 29, and is used to adjust the tension of the feeding timing belt 29 by adjusting the installation depth in the slot on the edge of the fixed top plate 23. The conveying roller 26 includes a synchronous gear 53, a bearing mounting surface 52, and a rough-surfaced roller 51 arranged coaxially from top to bottom. The conveying roller 26 meshes with the conveying synchronous belt 29 through the synchronous gear 53. In the two rows of conveying rollers 26, one row of conveying rollers 26 directly meshes with the conveying synchronous belt 29 through the synchronous gear 53, and the synchronous gear 53 of the other row of conveying rollers 26 meshes with the conveying synchronous belt 29 through the transmission gear, thereby realizing the opposite rotation of the two rows of conveying rollers 26 through a single conveying synchronous belt 29.

[0077] The conveying roller 26 is mounted in the bearing of the roller adjusting plate 24 via the bearing mounting surface 52. The rough-surfaced roller 51 is used to directly contact the material. In order to transport the material more effectively, the rough surface of the rough-surfaced roller 51 can be opened into a uniformly distributed fine groove type, pattern type or other anti-slip form.

[0078] After being sorted and processed, the materials wait at the entrance of the labeling platform 25. Depending on the size of different batches of materials, the spacing between the conveying rollers 26 on both sides can be adjusted using the roller spacing adjustment plate 24 to ensure that the materials are conveyed to the labeling position without damage. After adjusting the position of the conveying rollers 26, the conveying drive motor 28 drives the conveying timing belt 29 to rotate the conveying rollers 26. The conveying rollers 26 work in turn to convey the materials one by one to the labeling position. For different materials, adjusting the spacing of the conveying rollers 26 will cause the corresponding conveying timing belt 29 to become either loose or tight. Therefore, the tensioning block 27 installed on the fixed top plate 23 can be used to adjust the tension of the conveying timing belt 29, thus maintaining the power conveying function of the conveying rollers 26.

[0079] In further preferred embodiments, detailed schematic diagrams of the conveyor adjustment plate 24 are shown below. Figure 4As shown, the assembly includes a fixed plate 84, a roller moving plate 85, and locking screws 88. The fixed plate 84 has multiple fixing holes 87, through which it is fixedly installed on the bottom of the fixed top plate 23. The fixed plate 84 also has a groove perpendicular to the conveying direction of the conveying rollers 26. The roller moving plate 85 is slidably installed on both sides within the groove. The moving plate 85 has multiple parallel bearing holes 86, each for mounting a single row of multiple conveying rollers 26. The locking screws 88 are located in locking threaded holes on the side of the fixed plate 84, with the end of the screw abutting against the side of the roller moving plate 85. The roller moving plate 85 is connected to the fixed plate 84 via a nested groove. When adjusted to a suitable position, the position of the roller moving plate 85 can be fixed by the locking screws 88 on the head of the fixed plate 84.

[0080] The skewer feeding device includes a skewer conveyor chain plate 32 and a skewer clamping module 31. The skewer clamping module 31 is positioned above the skewer conveyor chain plate 32 and located on one side of the outlet end of the skewer-stringing platform 25. The skewer conveyor chain plate 32 is used to convey skewers from one end to the skewer-stringing position and to convey the skewered material to the finished product frame 33 at the other end. The skewer clamping module 31 is used to clamp the skewers located at the skewer-stringing position and thread the skewers from the outlet end of the skewer-stringing platform 25 onto the material on the skewer-stringing platform 25. The skewer conveyor chain plate 32 is used to transport the skewers to the area of ​​the skewer clamping module 31, where the skewer clamps and threads the material, and then returns it to its original position. When the skewers reach the edge of the skewer conveyor chain plate 32, the skewered material falls into the finished product frame 33 due to gravity.

[0081] In a preferred example, such as Figure 6As shown, the tack-clamping module 31 includes a gantry structure, tack-clamping fingers 62, tack-clamping finger cylinders 63, lifting cylinders 64, and a lead screw slide 65. The gantry structure is installed outside the tack-stringing position on the tack-feeding chain plate 32. A lead screw and nut mechanism is provided at the bottom of the top mounting plate of the gantry structure. The lead screw and nut mechanism is arranged in the direction from the outlet end of the tack-stringing platform 25 to the inlet end. The lifting cylinder 64 is slidably installed at the bottom of the lead screw and nut mechanism via the lead screw slide 65 and can move towards the outlet end of the tack-stringing platform 25 under the drive of the lead screw and nut mechanism. The tack-clamping finger cylinder 63 is fixedly installed on the piston rod at the bottom of the lifting cylinder 64. The tack-clamping fingers 62 are installed at the bottom of the tack-clamping finger cylinder 63 and are used to drive the tack-clamping fingers 62 to open and close. When the skewers reach the gripping area of ​​the clamping module 31, the intermediate cylinder 64 opens, pressing down the clamping finger cylinder 63 until the clamping fingers 62 contact the skewers. Then, the clamping finger cylinder 63 closes, securing the skewers in the two clamping fingers 62. Next, the intermediate cylinder 64 closes, and the clamping finger cylinder 63 rises. Immediately afterward, the lead screw slide 65 moves towards the skewer platform 25, thus driving the skewers to thread the material. Afterward, a return motion is performed, placing the skewers with the material back onto the conveyor chain plate 32.

[0082] In more preferred embodiments, the tag clamping module 31 further includes a material recognition camera 66, which is mounted at the bottom of the top mounting plate of the gantry structure. The lens of the material recognition camera 66 is positioned facing the tag stringing platform 25 to capture images of the materials located on the tag stringing platform 25. When the materials are waiting to be tagged, the movement of the conveying rollers 26 must stop to prevent the materials from falling off the tag stringing platform 25. Therefore, a material recognition camera 66 is used to determine whether the materials have reached the tag stringing position and coordinates with the start and stop of the conveying drive motor 28.

[0083] In more preferred examples, such as Figure 7 As shown, the skewer conveying chain 32 includes a chain plate body and a plurality of iron skewer conveying plates sequentially installed on the chain plate body along the conveying direction; the upper surface of the iron skewer conveying plate is provided with two fixing grooves 34, which are respectively used to fix the head end and tail end of the iron skewer, and a tip baffle 75 is provided at the front part of the fixing groove 34 at the front end, which is used to limit the tip of the iron skewer; the iron skewer conveying plate is provided with a plurality of chain plate mounting holes 73, and is fixedly installed on the chain plate body through the plurality of chain plate mounting holes 73.

[0084] This invention uses a three-axis linear module 13 for feeding materials into a stringing system. Then, a vibrating distribution line 15 with a diverter plate separates the materials into individual rows and transports them to the inlet of the stringing platform 25. For different materials, the spacing of the conveying rollers 26 is adjusted to ensure complete material transport. The materials are then strung onto metal skewers using a stringing device. Finally, the conveyor belt 32 transports the skewered materials to the finished product frame 33, completing the entire material stringing process.

[0085] This utility model, through the modular design of the feeding area, can complete the functions of material grabbing and feeding and single-row diversion, and arrange a pile of materials to be strung into a single row, which facilitates the subsequent feeding of materials by the feeding rollers 26.

[0086] This utility model, through the design of the feeding rollers 26 and the feeding adjustment plate 24 in the stringing area, can flexibly adjust the spacing of the feeding rollers 26. This ensures that the material is transported smoothly to the stringing area without damaging the material itself. Through the action of the tension block 27, it also ensures that the power of the feeding drive motor 28 can still be smoothly transmitted to the feeding rollers 26 after the spacing of the feeding rollers 26 is adjusted.

[0087] This invention, through the structural design of each module in the skewer supply area, enables the automatic conveying, gripping, and threading of iron skewers, thereby improving the overall automation level of the equipment.
