Description

Technical Field

[0001] The present application relates to the technical field of bar conveying, and in particular to a one-way travel mechanism. Background Art

[0002] Bars are a crucial product in the steel production industry. Accurate counting is crucial in the finishing and collection process. When counting finished bars, the bars are placed on a chain, which is driven forward by a motor drive to transport the bars. As the bars continue to move forward along the chain, they trigger the counter's detection device, generating a trigger signal. This signal is transmitted to the counting unit via a photoelectric sensor and proximity switch. The counting unit receives and processes this signal, and upon receiving a bar trigger signal, it counts the number of bars produced.

[0003] The current bar counting uses chain conveyor, which cannot ensure the chain's unidirectional movement. If the chain moves in the opposite direction, the number of bars will decrease or increase, resulting in counting confusion, causing errors in bar counting and failing to meet accurate counting requirements.

[0004] In view of this, the present application aims to provide a one-way travel mechanism to prevent the chain from moving in the opposite direction, thereby better solving the problem of bar counting accuracy. Summary of the Invention

[0007] Furthermore, the teeth have an inclination angle.

[0008] Furthermore, the rocker structure is provided with a driving rod and a rotating rod, the driving rod is rotationally connected to the pressure-contact structure and the rotating rod respectively, and the driving rod is connected to the teeth via a pawl.

[0009] Furthermore, the pressure touch structure is provided with a pressure touch seat, a pressure touch plate and an elastic member, the pressure touch seat and the pressure touch plate are coaxially rotatably connected with the ratchet, and the bottom end of the pressure touch seat is movably hinged to the driving rod, the elastic member is installed on the pressure touch seat, and the two ends of the elastic member are respectively in contact with the pressure touch seat and the pressure touch plate.

[0025] See also Figure 1As shown, the one-way travel mechanism described in this embodiment includes a ratchet 1, a rocker structure 2 and a driving structure 3. The ratchet 1 is provided with teeth 11. One end of the rocker structure 2 is connected to the teeth 11 through a pawl 4. The other end of the rocker structure 2 is in contact with the ratchet 1 through a pressure-contact structure 5. The driving structure 3 is drivingly connected to the rocker structure 2 and is used to drive the rocker structure 2 to move and rotate, achieve position change, and drive or limit the movement of the ratchet 1.

[0026] This embodiment has a simple structure and a reasonable design. When in use, the ratchet 1 is connected to the chain rotating shaft of the bar counting device. The rotating shaft of the chain here specifically serves as a supporting transmission shaft and is connected to the ratchet. When the chain moves forward, the ratchet 1 can rotate smoothly, and when the chain attempts to move in the reverse direction, the teeth 11 of the ratchet 1 will be stuck by the pawl 4 of the rocker structure 2, preventing the chain from moving in the reverse direction, thereby effectively realizing the unidirectional movement of the chain.

[0027] In some embodiments, the teeth 11 have an inclined angle.

[0028] In this embodiment, by providing teeth 11 with an inclined angle, the pawl 4 can more easily slide into the gap of the teeth 11 along the inclined angle when driving the ratchet 1 to rotate, thereby smoothly realizing unidirectional rotation. This setting also reduces friction and resistance, improves the operating efficiency and stability of the mechanism, and can cooperate with the pawl 4 during operation to transmit in one direction. When reverse movement occurs, it will be stuck to prevent reverse movement.

[0029] In some embodiments, the rocker structure 2 is provided with a driving rod 21 and a rotating rod 22 , the driving rod 21 is rotationally connected to the pressure-touch structure 5 and the rotating rod 22 respectively, and the driving rod 21 is connected to the teeth 11 through a pawl 4 .

[0030] Specifically, the pressure touch structure 5 is provided with a pressure touch seat 51, a pressure touch plate 52 and an elastic member 53. The pressure touch seat 51 and the pressure touch plate 52 are coaxially connected to the ratchet 1, and the bottom end of the pressure touch seat 51 is movably hinged to the driving rod 21. The elastic member 53 is installed on the pressure touch seat 51, and the two ends of the elastic member 53 are respectively in contact with the pressure touch seat 51 and the pressure touch plate 52.

[0031] This embodiment specifically shows the setting of the rocker arm structure 2 and the pressure-touch structure 5, the setting of the driving rod 21 and the rotating rod 22, so that the rocker arm structure 2 is more flexible and can respond more effectively to the drive of the driving structure 3, thereby driving the ratchet 1 to rotate. The pressure-touch structure 5 is composed of a pressure-touch seat 51, a pressure-touch plate 52 and an elastic member 53. This setting enables the pressure-touch structure 5 to be in close contact with the ratchet 1 and maintain continuous contact with the ratchet 1 through the elastic force of the elastic member 53, thereby ensuring that the unidirectional travel function of the mechanism is stable and reliable.

[0032] On the basis of the above embodiment, a pressure contact rod 54 is provided on the pressure contact seat 51 , and the elastic member 53 is sleeved on the pressure contact rod 54 and located inside the pressure contact seat 51 .

[0033] Specifically, a pressure contact piece 55 is provided at the bottom end of the pressure contact rod 54 , and the pressure contact piece 55 abuts against the pressure contact plate 52 .

[0034] This embodiment provides a pressure-touch rod 54, which makes the installation of the elastic member 53 more stable and more effectively provides elastic force, thereby maintaining close contact between the pressure-touch structure 5 and the ratchet 1. This also simplifies the structure of the mechanism, improving its reliability and durability. The pressure-touch plate 55 provided at the bottom end of the pressure-touch rod 54 enables the pressure-touch structure 5 to act more directly on the ratchet 1, thereby more effectively achieving the unidirectional travel function. Furthermore, the provision of the pressure-touch plate 55 also increases the contact area between the pressure-touch structure 5 and the ratchet 1, improving the stability and durability of the mechanism.

[0035] In some embodiments, the driving structure 3 is configured as a driving motor.

[0036] The driving structure 3 in this embodiment is configured as a driving motor, which improves the driving operation efficiency and flexibility.

[0037] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
