Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a flipping mechanism for testing chopsticks. Background Technology

[0002] Chopsticks are often engraved with patterns to enhance their aesthetics. Chopsticks are typically wider at one end than the other; the smaller end usually has a round cross-section, while the larger end often has a round or square cross-section. Existing chopstick inspection equipment uses industrial cameras to photograph and eliminate defective products, but the chopsticks are difficult to flip during transport, resulting in only one side being inspected, affecting the inspection results and efficiency. This limits the practicality of the equipment and prevents a comprehensive inspection of the chopsticks' surface quality. Utility Model Content

[0003] The purpose of this invention is to solve the problem that existing technologies have the disadvantage that chopsticks are inconvenient to flip during the conveying process, resulting in only one side of the chopsticks being inspected and screened. Therefore, this invention proposes a chopsticks flipping mechanism.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A chopsticks detection flipping mechanism includes a U-shaped frame, a chain conveyor belt for conveying chopsticks is provided inside the U-shaped frame, a limiting component is provided inside the U-shaped frame, the limiting component is used to limit and guide the chopsticks after flipping, and two industrial cameras for detecting chopsticks are provided on the upper side of the limiting component.

[0006] In order to flip the chopsticks, a set of flipping components is provided in the U-shaped frame. The flipping components are used to continuously flip the chopsticks. The U-shaped frame is also provided with a drive component that works in conjunction with the chain conveyor belt. The drive component is used to drive the flipping components to move when the chain conveyor belt is conveying the chopsticks.

[0007] In one possible design, the limiting components all include four limiting baffles disposed within the U-shaped frame, with the four limiting baffles arranged in pairs, and the two baffles in the same pair located on opposite sides of the chain conveyor belt.

[0008] Furthermore, the U-shaped frame is equipped with an adjustment assembly for adjusting the distance between the two limiting baffles.

[0009] In one possible design, the adjustment assembly includes a first groove formed within a U-shaped frame, two limiting rods fixed within the first groove, two U-shaped plates sliding on the surfaces of the two limiting rods, four limiting baffles respectively fixed to the adjacent ends of the two U-shaped plates, a bidirectional lead screw rotatably mounted within the first groove, two sliders fitted onto the surface of the bidirectional lead screw to engage with the positive and negative thread grooves on the surface of the bidirectional lead screw, the two sliders respectively fixed within the two U-shaped plates, and a handle fixedly mounted on the side end of the bidirectional lead screw that extends outward through the U-shaped frame.

[0010] The mechanism involves rotating a throttle to drive a bidirectional lead screw, which in turn causes two U-shaped plates to move closer together or further apart in a linear motion. Adjusting the distance between the two limit baffles allows for the adaptation of chopsticks of different lengths. The two limit baffles also help maintain the neatness of the chopsticks, facilitating inspection.

[0011] In one possible design, the limiting component further includes four inclined feeding plates, which are respectively fixed to the side ends of the two limiting baffles, and both inclined feeding plates are open in the direction in which the chopsticks enter.

[0012] In one possible design, the flipping assembly includes a second rotating shaft that rotates within a U-shaped frame. A cylinder is fixed to the surface of the second rotating shaft, and a plurality of rubber protrusions are uniformly fixed to the surface of the cylinder. The rotation direction of the cylinder is opposite to the movement direction of the chopsticks.

[0013] The cylinder drives multiple rubber protrusions to rotate, causing the protrusions to rub against the chopsticks in opposite directions, thus flipping the chopsticks over.

[0014] In one possible design, the drive assembly includes a first rotating shaft that rotates at the side end of the U-shaped frame, a first gear fixed to the surface of the first rotating shaft, a second gear meshing with the first gear fixed to the surface of the second rotating shaft, a drive shaft in the chain conveyor belt that moves outward through the side end of the U-shaped frame, a second synchronous pulley fixed to the surface of the first rotating shaft, a first synchronous pulley fixed to the surface of the drive shaft, and a conveyor belt driving the surfaces of the first and second synchronous pulleys.

[0015] The method of using a chain conveyor belt to transport chopsticks and drive the flipping assembly can reduce costs, and the meshing of the first gear and the second shaft can be used to reverse the rotation direction of the cylinder.

[0016] In one possible design, the side ends of the U-shaped frame are fixed with protective shells for protecting the drive components.

[0017] In one possible design, the protective shell is secured with bolts.

[0018] In this application, a drive motor drives a drive shaft to rotate, thereby driving a chain conveyor belt to transport chopsticks. The drive shaft drives a second synchronous wheel to rotate via a first synchronous wheel and the conveyor belt. The second synchronous wheel drives a first rotating shaft and a first gear to rotate. The meshing of the first gear and the second rotating shaft is used to reverse the rotation direction of the cylinder. The cylinder drives multiple rubber protrusions to rotate, causing the multiple rubber protrusions to rub against the chopsticks in opposite directions, thus flipping the chopsticks.

[0019] Rotating the throttle drives the bidirectional lead screw to rotate, which in turn causes two U-shaped plates to move closer or further apart in a linear motion. Adjusting the distance between the two limit baffles makes it easy to accommodate chopsticks of different lengths. The two limit baffles can keep the chopsticks neat and tidy, facilitating inspection.

[0020] Beneficial effects: In this utility model, the chopsticks flipping mechanism for detection achieves automated chopstick transport by setting up a chain conveyor belt, thereby improving detection efficiency. Simultaneously, the limiting components on both sides guide and limit the chopsticks before and after flipping, maintaining their neatness and facilitating accurate detection by an industrial camera, thus improving detection accuracy.

[0021] In this invention, the chopsticks detection flipping mechanism features an adjustable component design that allows for adjustment of the distance between the two limiting baffles, accommodating chopsticks of different lengths and expanding the mechanism's application range and versatility. The distance between the two limiting baffles is adjusted by rotating the handle to drive the bidirectional lead screw, making operation simple and convenient.

[0022] In this invention, the flipping component uses a cylindrical design with rubber protrusions. When the cylinder rotates, the rubber protrusions rub against the chopsticks in the opposite direction, causing the chopsticks to flip. This design is simple in structure, the flipping process is stable and reliable, and the rubber protrusions are soft and will not damage the chopsticks. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In one embodiment: Refer to Figures 1-4 A flipping mechanism for testing, applied in the field of testing equipment technology, includes a U-shaped frame 1, which serves as the main frame for mounting a chain conveyor belt 2 and a flipping assembly. The chain conveyor belt 2 is installed inside the U-shaped frame 1 and is used to transport chopsticks. The chain conveyor belt 2 is driven by a drive shaft that moves outward through the side end of the U-shaped frame 1.

[0030] Specifically, such as Figure 1 As shown, the chain conveyor belt 2 includes drive shafts rotatably mounted at both ends of the U-shaped frame 1. Two sprockets are mounted on the drive shafts, and a chain is installed between the two sprockets on the same side. Continuous U-shaped grooves are provided on the outer side of the chain for placing chopsticks. Two chains are arranged along the length of the U-shaped frame 1, and the U-shaped grooves on the two chains correspond one-to-one. Chopsticks are placed in the corresponding two U-shaped grooves. One of the drive shafts is connected to the output shaft of the drive motor. The connection method between the drive motor and the drive shaft, and the connection method between the drive motor and the power supply are conventional settings and will not be described in detail here.

[0031] like Figure 4 As shown, a set of flipping components is set inside the U-shaped frame 1. The flipping components include a second rotating shaft 13 that rotates inside the U-shaped frame 1. A cylinder 18 is fixed on the surface of the second rotating shaft 13. The cylinder 18 is located between two chains, and the height of the upper surface of the cylinder 18 is higher than the lower surface of the U-shaped groove. Multiple rubber protrusions 19 are evenly fixed on the surface of the cylinder 18. The rotation direction of the cylinder 18 is opposite to the movement direction of the chopsticks.

[0032] When the drive motor is powered on, it will drive the chain conveyor belt 2 to transport the chopsticks. The chopsticks will pass through the cylinder 18 in sequence. When the chopsticks move to the cylinder 18, they will be lifted up. At this time, the chopsticks are subject to gravity, limited by the side walls of the U-shaped groove on both sides, and pushed off by the cylinder 18 on the bottom. Therefore, when the cylinder 18 rotates in the opposite direction, it will drive multiple rubber protrusions 19 to rotate. The multiple rubber protrusions 19 drive the chopsticks to rotate together, causing the chopsticks to flip over.

[0033] The rubber ridge 19 can be designed as hemispherical ridges, serrated stripes or trapezoidal ridges, with a ridge height of 1-3mm, to fit chopsticks with different surface textures.

[0034] The U-shaped frame 1 contains a drive assembly that works in conjunction with the chain conveyor belt 2. The drive assembly includes a first rotating shaft 11 and a second rotating shaft 13 rotatably mounted on the U-shaped frame 1. The end of the first rotating shaft 11 extends out of the U-shaped frame 1 and is fixed with a first gear 12 and a second synchronous pulley 9. A second gear 14, meshing with the first gear 12, is fixed to the surface of the second rotating shaft 13. One end of the drive shaft extends out of the U-shaped frame 1 and is fixed with a first synchronous pulley 8. The surfaces of the first synchronous pulley 8 and the second synchronous pulley 9 are connected to the conveyor belt 10. When the chain conveyor belt 2 transports chopsticks, the drive motor is powered on, causing the drive shaft to rotate. The drive shaft, through the first synchronous pulley 8 and the conveyor belt 10, drives the second synchronous pulley 9 to rotate. The second synchronous pulley 9 then drives the first rotating shaft 11 and the first gear 12 to rotate. The meshing of the first gear 12 and the second gear 14 drives the second rotating shaft 13 to rotate, which in turn drives the rotating cylinder 18 to rotate. This allows for the simultaneous transport and flipping of the chopsticks without the need for an additional power source.

[0035] The side end of the U-shaped frame 1 is fixed with a protective shell for protecting the drive components, and the protective shell is fixed by bolts.

[0036] In another embodiment: Reference Figures 1-4An improvement on embodiment 1 is made as follows: A limiting assembly is installed within the U-shaped frame 1. Each limiting assembly includes four limiting baffles 4, arranged in pairs. Two baffles 4 in each pair are located on opposite sides of the chain conveyor belt 2. The four limiting baffles 4 are fixed to the adjacent ends of two U-shaped plates 3. An adjustment assembly is provided within the U-shaped frame 1 to adjust the distance between the two limiting baffles 4. Specifically, the adjustment assembly includes a first groove 15 within the U-shaped frame 1, within which two limiting rods 16 are fixed. Two U-shaped plates 3 slide on the surfaces of the two limiting rods 16. A bidirectional lead screw 17 is rotatably installed within the first groove 15. Two sliders, which engage with the positive and negative threaded grooves on the surface of the bidirectional lead screw 17, are fitted onto the surface of the bidirectional lead screw 17. The two sliders are fixed within the two U-shaped plates 3. The side end of the bidirectional lead screw 17 extends outwards through the U-shaped frame 1 and is fixed with a handle 7. Rotating the handle 7 drives the bidirectional lead screw 17 to rotate, which in turn causes the two U-shaped plates 3 to move closer or further apart in a linear motion, thereby adjusting the distance between the two limiting baffles 4 to accommodate chopsticks of different lengths. The two limiting baffles 4 maintain the neatness of the chopsticks, facilitating inspection. The limiting assembly also includes four inclined feeding plates 5, which are fixed to the sides of the four limiting baffles 4. All four inclined feeding plates 5 are open in the direction of chopstick entry, allowing the chopsticks to enter the limiting assembly smoothly. Industrial cameras are installed on the upper side of both limiting assemblies for detecting the chopsticks.

[0037] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
