Description

Technical Field

[0001] The present application relates to the technical field of chain conveyors, and more specifically, to a chain conveying mechanism. Background Art

[0002] Chain conveyor is a conveyor that uses chains to pull and carry materials, or slats, metal mesh belts and rollers installed on the chains. It can be divided into chain type, chain plate type, chain mesh type and slat type. Chain plate conveyor can meet the single-row conveying requirements of beverage labeling, filling, cleaning and other equipment. It can also make a single row into multiple rows and move slowly, thereby generating storage capacity to meet the large-scale feeding requirements of sterilizers, bottle storage tables and bottle coolers.

[0003] The existing chain conveyor lacks the function of centering the transported items. When the items need to be labeled, filled and cleaned, it is not easy to align with the corresponding labeling, filling and cleaning equipment. Deviations lead to errors in labeling, filling and cleaning, which is not conducive to the processing of items.

[0004] In order to solve the above problems, the present application provides a chain conveying mechanism. Utility Model Content

[0005] The present application provides a chain conveyor mechanism that adopts the following technical solution:

[0006] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0007] Through the above technical solution, the transported items can be centered through the clamping and centering mechanism so that they are located in the middle of the chain plate. The driving mechanism drives the bidirectional screw to rotate, so that the two bottom plates are close to each other, and then the two clamping plates are close to each other, so that the items on the chain plate can be pushed to be centered, solving the problem of easy deviation of the items and the corresponding labeling, filling and cleaning equipment.

[0008] Furthermore, the driving mechanism includes motor 2, a driving gear and a driven gear. Motor 2 is installed on the bottom surface of the slide frame through a motor seat, and the output end of motor 2 is fixedly connected to the driving gear. The bidirectional lead screw is threaded with the driven gear, and the driven gear and the driving gear are meshingly connected.

[0009] Through the above technical solution, the second motor drives the driving gear to rotate, thereby driving the driven gear to rotate, and further driving the bidirectional lead screw to rotate.

[0010] Furthermore, a plurality of reserved grooves are provided on the top surface of the slide frame, and pressure sensors are installed in the reserved grooves. A controller is installed on the side of the slide frame, and the controller is electrically connected to the pressure sensor and the motor.

[0011] Through the above technical solution, objects that are not in the middle can be detected through the pressure sensor, and the pressure sensor transmits a signal to the controller. The controller is equipped with a PLC program. When the pressure sensor transmits a signal, the controller drives the second motor to operate, thereby realizing the function of automatically centering the objects.

[0012] Furthermore, a sliding block is fixedly connected between the clamping plate and the base plate, and the sliding block is slidably matched with the sliding groove.

[0013] Through the above technical solution, the slider can limit and guide the movement of the base plate.

[0014] Furthermore, transition plates are provided at both upper and lower ends of the chain plate, and the two transition plates are relatively distributed.

[0015] Through the above technical solution, the transition plate can guide the objects, making them more stable and smooth when entering or leaving the chain plate.

[0016] Furthermore, a plurality of tensioning slider support seats are installed on the top surface of the chain plate, and the plurality of tensioning slider support seats are equidistantly distributed.

[0017] Through the above technical solution, the object can be limited by tightening the slider support seat, thereby increasing the static friction between the slider support seat and the chain plate.

[0018] Furthermore, an elastic plate is fixedly connected between the opposite surfaces of the two clamping plates, and the elastic plate is a rubber plate.

[0019] Through the above technical solution, the elastic plate made of rubber material can reduce the damage to the object during the pushing and centering process.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] The clamping and centering mechanism can be used to center the transported items so that they are located in the middle of the chain plate. The driving mechanism drives the bidirectional lead screw to rotate, so that the two bottom plates are close to each other, and then the two clamping plates are close to each other, so that the items on the chain plate can be pushed to be centered, solving the problem of easy deviation between the items and the corresponding labeling, filling and cleaning equipment.
