Description

Technical Field

[0001] This utility model relates to the field of cutting tooth conveying and feeding technology, specifically a cutting tooth conveying and feeding device. Background Technology

[0002] As a key and vulnerable component of heavy machinery in mining, road construction, and other industries, the quality and production efficiency of cutting teeth directly affect the progress and cost of engineering operations. In the production process of cutting teeth, the transportation and feeding process is an important link to ensure production continuity and product quality. Efficient and accurate transportation and feeding can ensure that the cutting tooth blanks enter the processing stage in a timely and accurate manner, avoiding production stoppages caused by insufficient material supply or feeding errors.

[0003] However, traditional cutting tooth conveying and feeding devices have many problems. In terms of transportation stability, common conveying methods often cannot guarantee the stability of the cutting teeth during transportation. Many traditional devices use simple conveyor belts or manual handling. During transportation, the cutting teeth are prone to displacement and damage due to shaking and collision. This not only affects the quality of the cutting teeth, but also increases the scrap rate and production costs. Moreover, due to the lack of effective support and guiding structures, the conveying device is prone to problems such as deviation and jamming during operation, which further reduces transportation efficiency.

[0004] Traditional devices also perform poorly in terms of positioning accuracy. When transporting the cutting teeth to the designated loading position, it is difficult to achieve precise control. This often results in inaccurate gripping positions when the robot arm grabs the cutting teeth for loading, requiring multiple adjustments to complete the loading operation. This seriously affects loading efficiency and production continuity. Inaccurate positioning may also cause deviations in the cutting teeth during processing, affecting the precision and quality of the product.

[0005] In summary, in order to solve the aforementioned problems of traditional cutting tooth conveying and feeding devices, improve transportation stability, positioning accuracy and intelligence, and reduce equipment failure rate and production costs, we provide a cutting tooth conveying and feeding device to solve these problems.

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a cutting tooth conveying and feeding device.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a cutting tooth conveying and feeding device, comprising a conveying plate for conveying cutting teeth, a base, a robot arm fixed on the base, a support column, and a conveying frame fixed above the support column. A stepper motor is arranged in the middle of the conveying frame, and a threaded disc is fixed to the output shaft of the stepper motor.

A rotating shaft is fixed to both ends of the threaded rod. A bearing is sleeved on the surface of the rotating shaft. The bottom end of the bearing is fixed to the surface of the conveying frame through a fixing block. A semi-circular threaded block is threadedly connected to the surface of the threaded rod. The surface of the semi-circular threaded block is fixed to the bottom end of the conveying plate. A slider is uniformly fixed to the bottom end of the conveying plate. A pressure sensor is fixed to one end of the slider. A support plate is fixed on the conveying frame. A movable plate passes through the support plate.

[0015] (III) Beneficial Effects:

[0016] Compared with existing technologies, this cutting tooth conveying and feeding device has the following advantages:

[0017] I. This utility model provides comprehensive and stable support for the conveyor plate by setting a slider at the bottom of the conveyor plate to cooperate with the guide rail on the surface of the conveyor frame, and by having the support wheel on the side of the conveyor frame overlap with the inner side of the conveyor plate. This greatly reduces the shaking and collision of the cutting teeth during transportation. This not only reduces the risk of displacement and damage of the cutting teeth and ensures the quality of the cutting teeth, but also reduces the scrap rate and effectively saves production costs. At the same time, the stable transportation process avoids problems such as deviation and jamming of the conveying device, significantly improves transportation efficiency, and ensures the continuity of production.

[0018] II. This utility model achieves precise control of the conveyor plate position through the precise transmission of the threaded disc and threaded rod driven by a stepper motor, and the cooperation of a pressure sensor and a pressure trigger. When the conveyor plate moves to a specific position, the pressure sensor is triggered, and the processing unit controls the stepper motor to stop, so that the conveyor plate stops accurately at the designated feeding position. This allows the robot arm to accurately grasp the cutting teeth for feeding without multiple adjustments, greatly improving feeding efficiency and production continuity, while ensuring the positional accuracy of the cutting teeth during processing and improving product quality.

[0019] Third, this utility model achieves automated transportation, positioning, and loading through a processing unit, a counting module, and a storage module. The processing unit automatically controls the movement of the stepper motor and the robotic arm based on the signal from the pressure sensor, requiring minimal manual intervention, reducing labor intensity, improving work efficiency, and minimizing human error. The counting module records the number of times the robotic arm loads and the quantity of cutting teeth transported in real time, and stores the data in the storage module, facilitating enterprise monitoring and management of the production process and providing data support for production process optimization and efficiency improvement.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-5 As shown, this utility model provides a technical solution: a cutting tooth conveying and feeding device, including a conveying plate 1 for conveying cutting teeth, a base 5, a robot arm 4 fixed on the base 5, a support column 6, and a conveying frame 7 fixed above the support column 6. A stepper motor 17 is disposed in the middle of the conveying frame 7. A threaded disc 16 is fixed to the output shaft of the stepper motor 17. A threaded rod 15 is threadedly connected to the upper surface of the threaded disc 16. The threaded rod 15 has gradually decreasing slopes at both ends. This slope design allows for rapid threaded connection and separation between the threaded rod 15 and the semi-circular threaded block 14, making its movement more stable. A rotating shaft 12 is fixed to both ends of the threaded rod 15. The conveyor plate 1 has a bearing 13 fitted onto its surface. The bottom end of the bearing 13 is fixed to the surface of the conveyor frame 7 via a fixing block 11. A semi-circular threaded block 14 is threaded onto the surface of the threaded rod 15. The surface of the semi-circular threaded block 14 is fixed to the bottom end of the conveyor plate 1. The design of driving the threaded disc 16 and the threaded rod 15 by the stepper motor 17 can precisely control the position of the conveyor plate 1. By starting and stopping the stepper motor 17, the conveyor plate 1 can be moved step by step on the conveyor frame 7, thereby accurately transporting the cutting teeth to the designated position for feeding. This not only improves the accuracy of feeding, but also reduces the damage to the cutting teeth or feeding failure caused by positional deviation, and greatly improves production efficiency.

[0028] Slider 10s are evenly fixed at the bottom of the conveyor plate 1. The sliders 10s cooperate with the guide rails 9 on the surface of the conveyor frame 7 to ensure the smooth movement of the conveyor plate 1. A pressure sensor 23 is fixed at one end of the slider 10. A support plate 18 is fixed on the conveyor frame 7. A movable plate 19 passes through the support plate 18. A slide rod 21 passes through the support plate 18. Both ends of the slide rod 21 are connected to the movable plate 19. A spring 20 is sleeved on the surface of the slide rod 21 between one side of the support plate 18 and the movable plate 19. A pressure trigger 22 adapted to the pressure sensor 23 is fixed at one end of the movable plate 19. The pressure trigger 22 and the pressure sensor 23 are connected to the processing unit 24 through wires. When the processing unit 24 is connected to the stepper motor 17, storage module 25, and robot arm 4 via wires, and the storage module 25 and robot arm 4 are connected to the counting module 26 via wires, the processing unit 24 can receive the signal when the pressure trigger 22 triggers the pressure sensor 23. It then controls the stepper motor 17 according to a preset program. For example, when the conveyor plate 1 is moved to a specific position on the conveyor frame 7 by the stepper motor 17 via the threaded disc 16, threaded rod 15, and semi-circular threaded block 14, the pressure sensor 23 is triggered, and the processing unit 24 controls the stepper motor 17 to stop, ensuring the conveyor plate 1 stops accurately. Simultaneously, the processing unit 24 is also connected to the storage module 25 and robot arm 4, enabling it to record transportation data and control the robot arm 4 to perform loading operations. Through the start and stop of the stepper motor 17 and the cooperation of the pressure sensor 23 and pressure trigger 22, the conveyor plate 1 gradually moves and loads materials, achieving intelligent control of the transportation and loading process and improving the automation level of the production process.

[0029] Specifically, the universal wheels 2 at the bottom of the conveyor plate 1 make it more convenient to transport or move the conveyor plate 1 in the initial stage or over short distances. Operators can easily move the conveyor plate 1 filled with cutting teeth to the vicinity of the conveyor frame 7. The cutting teeth holes 3 evenly opened on the surface of the conveyor plate 1 can position and classify the cutting teeth, which is convenient for transportation and loading. At the same time, it can also improve transportation efficiency and reduce the chaos and collision of cutting teeth during transportation.

[0030] Working principle:

[0031] First, the operator uses the casters 2 at the bottom of the conveyor plate 1 to move the conveyor plate 1, which has the cutting teeth placed in it (the cutting teeth are placed in the cutting tooth holes 3 evenly opened on the surface of the conveyor plate 1), to the vicinity of the conveyor frame 7. Then, the conveyor plate 1 is made to cooperate with the guide rail 9 on the surface of the conveyor frame 7 through the sliders 10 evenly fixed at the bottom, so that the conveyor plate 1 can move along the guide rail 9. When the conveyor plate 1 moves to the surface of the conveyor frame 7, the support wheels 8 evenly arranged on the side of the conveyor frame 7 overlap with the inner side of the conveyor plate 1, providing stable support for the conveyor plate 1 and ensuring that its subsequent movement is smooth.

[0032] The stepper motor 17 in the middle of the conveyor frame 7 is started. The output shaft of the stepper motor 17 drives the threaded disc 16 fixed to it to rotate. Since the threaded disc 16 is threadedly connected to the threaded rod 15, the rotation of the threaded disc 16 causes the threaded rod 15 to move accordingly with the cooperation of the rotating shafts 12 and bearings 13 at both ends. The gradually decreasing slope set at both ends of the threaded rod 15 helps it to move more stably and smoothly. The surface of the threaded rod 15 is threadedly connected to the semi-circular threaded block 14, and the surface of the semi-circular threaded block 14 is fixed to the bottom end of the conveyor plate 1. Therefore, as the threaded rod 15 moves, the semi-circular threaded block 14 drives the conveyor plate 1 to move along the guide rail 9, thereby realizing the transportation of the cutting teeth.

[0033] During the movement of the conveyor plate 1, the pressure sensor 23, which is fixed at one end of the bottom slider 10 of the conveyor plate 1, will move together with the conveyor plate 1. When the conveyor plate 1 moves to a specific position, the pressure sensor 23 will interact with the pressure trigger 22, which is fixed at one end of the movable plate 19 in the support plate 18. When the pressure trigger 22 triggers the pressure sensor 23, the pressure sensor 23 will transmit the signal to the processing unit 24 through the wire.

[0034] After receiving the signal from the pressure sensor 23, the processing unit 24 controls the stepper motor 17 and the robot arm 4 according to the preset program. On the one hand, the processing unit 24 controls the stepper motor 17 to stop running, so that the conveyor plate 1 stops accurately at the designated loading position. On the other hand, the processing unit 24 sends an instruction to the robot arm 4, so that the robot arm 4 fixed on the base 5 can start to perform the loading operation of the cutting teeth. At the same time, throughout the process, the counting module 26 records the number of loading operations of the robot arm 4 and the number of cutting teeth transported, and stores these data in the storage module 25 for subsequent production statistics and analysis.

[0035] When the pressure trigger 22 triggers the pressure sensor 23, the movable plate 19 will be subjected to a certain impact force. At this time, the slide rod 21 passing through the support plate 18 and the spring 20 sleeved on the surface of the slide rod 21 play a role. The elasticity of the spring 20 can buffer this impact force, prevent the movable plate 19 and the pressure sensor 23 from being damaged due to excessive instantaneous impact force, and ensure the normal operation and service life of the equipment.
