Description

Technical Field

[0001] This utility model relates to the field of knotting machine technology, and in particular to a material conveying structure for a konjac knotting machine. Background Technology

[0002] Konjac is a perennial herbaceous plant whose main component is glucomannan. It also contains various amino acids that the human body cannot synthesize, as well as minerals such as calcium, zinc, and copper. It is a high-quality dietary fiber that is low in fat, sugar, and calories and contains no cholesterol. Konjac strips are strip-shaped food products made from konjac starch. To make them easier to eat (mainly for holding with chopsticks), the konjac strips are usually tied in knots.

[0003] Currently, the feeding technology in the konjac strip knotting process has significant shortcomings. Most konjac knotting machines in the industry use a continuous feeding mode. At the moment of knotting, the continuously conveyed konjac strip accumulates and becomes tangled at the knotting point. Furthermore, different types of konjac products have diverse requirements for the size and shape of the knotted konjac strip, and continuous feeding cannot precisely control the conveying length and timing of the konjac strip based on these differences. This forces workers to frequently intervene manually in the feeding process, which not only significantly reduces production efficiency but also leads to inconsistent product quality due to inconsistent manual operation, making it difficult to meet the market's demand for standardized, high-quality konjac products.

[0004] Therefore, the applicant proposes a material conveying structure for a konjac knotting machine to achieve intermittent feeding, providing a stable working object for the knotting operation and ensuring the quality and stability of the knotting. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a material conveying structure for a konjac knotting machine, which realizes intermittent feeding, provides a stable working object for knotting operation, and ensures the quality and stability of knotting, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a material conveying structure for a konjac knotting machine, including a mounting bracket, a conveying structure mounted on the mounting bracket, a receiving cylinder located on one side of the material output end of the conveying structure, a cylinder connecting plate on the front side wall of the receiving cylinder near the conveying structure, and a probe rod on its rear side wall, a fixing rod on the mounting bracket, the cylinder connecting plate and the probe rod rotatably mounted on the fixing rod, a proximity switch at the bottom of the mounting bracket, an arc-shaped guide hole on the probe rod, and a guide post protruding from the side wall of the mounting bracket, the guide post being located within the guide hole. When the conveying structure feeds a certain amount of material into the receiving cylinder, the receiving cylinder rotates around the fixing rod under the weight of the material. The probe rod approaches the proximity switch, triggering the proximity switch. When the proximity switch is triggered, the conveying structure stops feeding material.

[0007] Furthermore, a motor mounting bracket is installed on the back of the mounting bracket, and a material conveying motor is installed on the back of the motor mounting bracket. The motor shaft of the material conveying motor passes through the side wall of the motor mounting bracket and is fixed with a drive sprocket. The mounting bracket is provided with feeding components on both sides of the drive sprocket. The feeding components include a connecting shaft that is rotatably connected to the mounting bracket. A driven sprocket is fixed at the rear end of the connecting shaft, and a conveying roller is fixed at the front end of the connecting shaft. The two driven sprockets are connected to the drive sprocket through chain drive. An adjustable guide is provided on the front side of the mounting bracket between the two conveying rollers.

[0008] Furthermore, the adjustable guide includes a movable plate with a vertically arranged strip hole. A guide rod is provided at the bottom of the movable plate in the strip hole, and the movable plate is connected to the mounting bracket by bolts passing through the strip hole.

[0009] Furthermore, the conveying roller includes two fixed discs spaced apart from each other, and a plurality of fixed teeth are provided between the edges of the two fixed discs, the plurality of fixed teeth being arranged in a circle concentric with the fixed discs.

[0010] Furthermore, the outer surface of the fixed toothed rod is toothed.

[0011] Furthermore, the probe includes a cylinder fixing plate fixed to the receiving cylinder and inclined downwards outwards from the receiving cylinder. A load-bearing handle is fixed to the outer end of the cylinder fixing plate. A branch rod is provided on one side of the cylinder fixing plate, and a swing rod is fixed to the outer end of the branch rod.

[0012] Furthermore, a U-shaped rod is provided at the top of the end of the receiving cylinder away from the conveying structure.

[0013] Beneficial effects

[0014] Compared with the prior art, the present invention has at least the following advantages:

[0015] 1. This utility model enables intermittent feeding, which allows the material to be temporarily stopped after being fed for a certain length, providing a stable working object for the knotting operation and ensuring the quality and stability of the knotting.

[0016] 2. This utility model controls the feeding by adjusting the weight of the material received by the receiving cylinder. When the weight of the konjac strip received by the receiving cylinder reaches a certain level, the receiving cylinder tilts, causing the probe to approach the proximity switch and triggering the proximity switch. At this time, the material conveying power supply stops. After the konjac strip in the receiving cylinder is reduced due to knotting and consumption, and the weight decreases, feeding can resume, thereby achieving precise intermittent feeding.

[0025] See Figures 1-4A material conveying structure for a konjac knotting machine includes a mounting bracket 1, which is fixed to the knotting equipment via a connecting column 14. A conveying structure is provided on the mounting bracket 1, comprising an L-shaped motor mounting frame 10 mounted on the back of the mounting bracket 1. A material conveying motor 7 is mounted on the back of the motor mounting frame 10, and the motor shaft of the material conveying motor 7 passes through the side wall of the motor mounting frame 10 and is fixed to a drive sprocket 9. Feeding assemblies 8 are respectively provided on both sides of the drive sprocket 9 on the mounting bracket 1. Each feeding assembly 8 includes a connecting shaft 81 rotatably connected to the mounting bracket 1. A driven sprocket 80 is fixed to the rear end of the connecting shaft 81, and a conveying roller 82 is fixed to the front end of the connecting shaft 81. The two driven sprockets 80 are connected to the drive sprocket 9 via chain drive. The conveying roller 82 includes two circular fixed disks 820 spaced apart. Multiple fixed toothed rods 821 are arranged between the edges of the two fixed disks 820 in a circular arrangement concentric with the fixed disks 820, meaning the center of the circular arrangement coincides with the center of the fixed disks 820. The outer surface of each fixed toothed rod 821 is toothed. An adjustable guide 2 is located between the two conveying rollers 82 on the front side of the mounting bracket 1. This adjustable guide 2 includes a movable plate 22 with a vertically oriented strip hole 21. A guide rod 20 is located at the bottom of the strip hole 21 on the movable plate 22. A mounting hole 11 is provided on the front side of the mounting bracket 1, and a bolt is threaded into the mounting hole 11. The movable plate 22 is connected to the mounting bracket 1 via this bolt passing through the strip hole 21, thereby fixing the adjustable guide 2 to the mounting bracket 1. The height of the guide rod 20 can be adjusted by locking the bolt at different positions in the strip hole 21. During operation, the material conveying motor 7 operates, driving the drive sprocket 9 to rotate. The rotation of the drive sprocket 9, through the chain, drives the two driven sprockets 80 to rotate. The two driven sprockets 80 rotate synchronously, driving the conveying roller 82 to rotate. The material is conveyed from the top of the right conveying roller 82, around the bottom of the guide rod 20, and then around the top of the left conveying roller 82 again, thus conveying the material from right to left.

[0026] A receiving cylinder 3 is located on one side of the material output end of the conveying structure. A cylinder connecting plate 30 is located on the top of the front side wall of the receiving cylinder 3 near the conveying structure, and a probe rod 5 is located on the top of its rear side wall. A U-shaped rod 31 is located on the top of the receiving cylinder 3 away from the conveying structure. A fixing rod 4 is located at the bottom of the mounting bracket 1. The cylinder connecting plate 30 and the probe rod 5 are rotatably mounted on the fixing rod 4, enabling the top of the receiving cylinder 3 near the conveying structure to be rotatably connected to the mounting bracket 3. The probe rod 5 includes a cylinder fixing plate 50 fixed to the receiving cylinder 3 and inclined downwards outwards. A load-bearing handle 51 is fixed to the outer end of the cylinder fixing plate 50. A branch rod 53 is located on the outer side of the cylinder fixing plate 50, and a swing rod 54 is fixed to the outer end of the branch rod 53. A proximity switch 6 is located at the bottom of the mounting bracket 1. The cylinder fixing plate 50 is provided with a guide hole 52, and the mounting bracket 1 is provided with a protruding post 12. The protruding post 12 is located in the guide hole 52. The receiving cylinder 3 rotates around the fixing rod 4, and the guide hole 52 restricts its rotation path.

[0027] Under the action of the material conveying motor 7, the material passes sequentially through the top of the right conveying roller 82, the bottom of the guide rod 20, and the top of the left conveying roller 82, and then enters the receiving cylinder 3 for partial storage. It then passes through the U-shaped rod 31 and is conveyed forward by the conveying mechanism of the conveying station to the knotting station for knotting. It should be noted that the conveying station is located on the left side of this invention for conveying the konjac strip, while the knotting station is located to the left of the conveying station for knotting the konjac strip. When the material stored in the receiving cylinder 3 reaches a certain weight, since the right side of the receiving cylinder 3 is rotatably connected to the mounting bracket 1, and the other side is a free side, the receiving cylinder 3 rotates counterclockwise under the weight of the material it contains. The probe rod 5 swings counterclockwise accordingly, and the swing rod 54 swings upwards towards the proximity switch 6, triggering the proximity switch 6. The proximity switch 6 transmits its output proximity switch signal to the controller of the knotting machine. The controller receives the proximity switch signal and controls the material conveying motor 7 to stop working. The conveying mechanism at the conveying station advances the material a certain length to the knotting station for knotting. As the material in the receiving cylinder 3 decreases due to knotting, the weight of the receiving cylinder 3 drops, and the swing arm 54 moves away from the proximity switch 6. The proximity switch 6 outputs a non-triggered state signal to the controller. Upon receiving this signal, the controller controls the material conveying motor 7 to continue operating, conveying material into the receiving cylinder 3 until the material in the receiving cylinder 3 reaches a certain weight, triggering the proximity switch. At this point, the material conveying motor 7 stops operating, and the conveying mechanism at the conveying station advances a certain length for knotting, reducing the weight of the receiving cylinder 3. The swing arm 54 moves away from the proximity switch 6, and then material continues to be conveyed into the receiving cylinder 3. This cycle repeats, achieving intermittent material delivery to the conveying station. Intermittent feeding allows the material to temporarily stop after being fed a certain length, providing a stable working object for the knotting operation and ensuring the quality and stability of the knotting. A counterweight can be loaded onto the load handle 51 to adjust the weight of material that the receiving cylinder 3 can accept.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
