Description

TECHNICAL FIELD

[0001] The utility model relates to a flow line technical field, specifically relates to a step flow line. BACKGROUND

[0002] In many fields such as modern industrial production and logistics transportation, the conveying of materials is a crucial link, and its efficiency and stability directly affect the performance of the entire production system and product quality. Traditional conveying equipment has many problems in actual application, which are briefly described as follows:

[0003] In terms of transmission control, traditional conveying equipment often has difficulty in achieving high-precision speed and position control. Many conveying belts driven by ordinary motors have inaccurate speed control, which can easily cause speed fluctuations, resulting in the inability of materials to accurately stop at designated positions during the conveying process. Moreover, the process of adjusting conveying parameters for traditional equipment when facing different production demands is complex and time-consuming, requiring a large amount of manual mechanical adjustment, which cannot quickly adapt to changes in product specifications, seriously affecting production efficiency and the flexibility of the equipment.

[0004] The stability of the conveying process is also a major challenge faced by traditional conveying equipment. Traditional conveying belts are prone to problems such as slackness and deviation after long-term operation. This is because they lack effective tensioning and supporting devices, or the related devices are designed unreasonably. When the conveying belt is slack, the friction between it and the driving roller decreases, which can easily cause slipping, making it difficult for materials to be conveyed normally. Deviation of the conveying belt can cause materials to slide off the belt, resulting in material loss, and even damage to the equipment.

[0005] The mobility and fixity of the equipment also present inconveniences in actual use. Some traditional conveying equipment is fixed in position after installation and cannot be moved according to changes in production layout or temporary needs. When an enterprise needs to adjust the layout of the production line, relocate equipment, or use the conveying equipment flexibly between different work areas, the fixed installation method of traditional equipment can cause great difficulties. A lot of manpower and time are needed for disassembly, transportation, and reinstallation, increasing production costs and equipment idle time. Even some equipment is equipped with a mobile device, but it is often difficult to achieve stable fixation after moving, affecting the normal operation of the equipment.

[0006] Insufficient safety protection performance is another important problem of traditional conveying equipment. Many traditional conveying equipment lacks thorough consideration of the safety protection of operating personnel in design and lacks effective protection devices. Operating personnel can easily accidentally contact the conveying mechanism during equipment operation. In industrial production sites, personnel frequently operate equipment at close range. This safety hazard can cause serious personal injury accidents and threaten the safety of operating personnel.

[0007] The convenience of motor installation and maintenance also needs to be improved in traditional conveying equipment. The installation position of the motor in the traditional equipment is often not reasonable, the installation and disassembly process is complex, professional tools are needed and a lot of time is spent. When the motor needs to be repaired or replaced due to failure, the complex installation structure increases the difficulty of repair and downtime, seriously affecting the continuity of production. Moreover, the motor is easily affected by external factors (such as dust, moisture, collision, etc.) during operation, and lacks effective protection measures, which further reduces the reliability and service life of the motor, increases the maintenance cost and operation risk of the equipment. Practical new type content

[0008] To solve the problems raised in the background art, the utility model provides a step-by-step assembly line which is simple in structure, high in control precision, stable in conveying process, convenient to move, high in safety protection, and convenient to maintain.

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a step-by-step assembly line, comprising a rack and a conveying mechanism and a power mechanism installed on the rack, the conveying mechanism comprising a conveying belt, a driving roller, a first driven roller and a second driven roller, the first driven roller being installed horizontally on the upper side of the front end of the rack, the second driven roller being installed horizontally on the upper side of the rear end of the rack and being located on the same horizontal plane as the first driven roller, the driving roller being installed horizontally on the lower end of the first driven roller, the conveying belt being wrapped around the outer periphery of the driving roller, the first driven roller and the second driven roller, the power mechanism comprising a stepping motor, the stepping motor being installed on the lower end of the driving roller, the transmission shaft of the stepping motor being connected with the driving roller and driving the driving roller to rotate relative to the rack, under the cooperation of the first driven roller and the second driven roller, the conveying belt is driven to convey forward or backward along the horizontal direction relative to the rack.

[0010] As a further elaboration of the technical solution:

[0011] Preferably, the conveying mechanism further comprises a first supporting roller and a second supporting roller, the first supporting roller being installed horizontally on the rack between the driving roller and the first driven roller at the rear end of the driving roller, the second supporting roller being installed horizontally on the rear side of the middle part of the rack, the conveying belt being wrapped around the upper side of the first supporting roller and the second supporting roller, the first supporting roller and the second supporting roller cooperating with each other to tension and support the conveying belt, so as to ensure stable conveying of the conveying belt.

[0013] Preferably, the power mechanism further comprises a motor mounting seat fixed to the inner periphery of the protective plate at the right end of the frame, and the stepping motor is mounted on the motor mounting seat.

[0014] Preferably, a control mechanism is further arranged on the frame at the lower side of the rear end, electrically connected with the stepping motor and controlling the operation of the stepping motor.

[0015] Preferably, retractable supporting legs are arranged around the lower end of the frame, used for retracting upward to facilitate the movement of the frame or retracting downward to support and fix the frame, and universal wheels are arranged on the inner periphery of the retractable supporting legs and used for moving the frame.

[0016] Compared with the prior art, the utility model has the advantages that:

[0017] Firstly, the utility model uses a stepping motor as a power source, accurately controls the operation of the stepping motor through a control mechanism, and can realize high-precision control of the conveying speed and position of the conveying belt. Since the step angle of the stepping motor is fixed, the motor will rotate by a corresponding angle accurately after each input of a pulse signal, thereby driving the driving roller to realize accurate angular displacement and accurately controlling the conveying distance and speed of the conveying belt. The speed and start-stop position of the conveying belt can be conveniently changed through the control mechanism, without the need for complex mechanical adjustment, thereby improving the adaptability and production flexibility of the equipment.

[0018] Secondly, the utility model has high conveying stability, the first driven roller and the second driven roller are transversely arranged on the upper sides of the front end and the rear end of the frame and located on the same horizontal plane, and together with the driving roller support the conveying belt, so that the conveying belt can keep a stable running track in the horizontal direction. Meanwhile, the first supporting roller and the second supporting roller cooperate with each other to play a role in tensioning and supporting the conveying belt, effectively preventing the problems such as loosening and deviation of the conveying belt during operation, and ensuring the stable conveying of the conveying belt. The roller supporting plate provides stable mounting support for the two ends of the driving roller, the first driven roller and the first supporting roller, can reduce vibration and shaking, helps to prolong the service life of the driving roller, the first driven roller, the first supporting roller and the conveying belt, reduces the equipment maintenance cost, and improves the reliability of the equipment operation.

[0019] Thirdly, the retractable supporting legs and the universal wheels arranged around the lower end of the frame make the equipment retract upward through the retractable supporting legs when the equipment needs to be moved, and the universal wheels are used to conveniently move the frame to a specified position; when the equipment is running, the retractable supporting legs retract downward to stably support and fix the frame. This design facilitates the layout adjustment, equipment installation and maintenance of the equipment in the workshop, improves the use convenience and space utilization rate of the equipment.

[0020] Fourthly, the safety protection is high, the vertical protection plates arranged on the left side and the right side of the front end of the rack effectively prevent the operator from accidentally contacting the conveying mechanism during the operation of the equipment, avoid safety accidents such as pinching and winding, and protect the personal safety of the operator. On the automatic production line, the protection plate can be used as a physical barrier to prevent the operator from misoperation into the dangerous area, and improve the safety of the production environment.

[0021] Fifthly, the motor mounting seat in the power mechanism is fixed in the inner wall of the right end protection plate of the rack, which provides a stable mounting position for the stepping motor. This design facilitates the installation and disassembly of the stepping motor, and when the stepping motor needs to be repaired or replaced, the operator can operate more conveniently, reduce the equipment downtime, and improve the production efficiency. At the same time, the fixed position of the motor mounting seat also helps to protect the stepping motor from external factors (such as collision, dust, moisture, etc.), prolonging the service life of the stepping motor.
