Description

Technical Field

[0001] The utility model relates to a printing machine, in particular to a conversion automatic material receiving mechanism. Background Art

[0002] Printing presses include a rewinding mechanism. To avoid wasted time loading and unloading the coil during the rewinding and unwinding process, existing rewinding mechanisms incorporate alternating components to compensate for this time. This arrangement requires a rewinding drive component to be installed on each corresponding rewinding roller. When performing the rewinding operation, workers must individually control each rewinding drive component. Furthermore, this operation must be completed within a short timeframe, significantly increasing the worker's workload and easily leading to control errors, which can cause errors in work. The present utility model was proposed to address these issues. Utility Model Content

[0003] The purpose of the utility model is to provide a conversion automatic material receiving mechanism, which can realize automatic control of each winding drive component, thereby reducing the control workload and ensuring that the work is carried out in an orderly manner.

[0004] The above technical purpose of the present utility model is achieved through the following technical solutions: a conversion automatic material receiving mechanism, including a frame, a switching component arranged on the frame, at least two material receiving rollers installed on the switching component and a winding drive component connected to each material receiving roller, the switching component has a winding position and drives each material receiving roller to pass through the winding position in sequence, the frame is located at one end of the switching component along the coil transmission direction and is provided with a propulsion roller, the propulsion roller is connected to a propulsion component that drives the propulsion roller to move along the coil transmission direction, the propulsion roller movement has a first stroke and a second stroke, corresponding to the second stroke there is a sensor, the sensor is connected to a controller and the controller is connected to the propulsion component and each winding drive component.

[0005] With this technical solution, after the winding drive assembly drives the take-up roller in the rewinding position to complete winding, the switching assembly switches the take-up roller out of the rewinding position and allows the next take-up roller to enter the rewinding position. A controller then controls the propulsion member to drive the propulsion roller. When the propulsion roller enters the second stroke from the first stroke, a trigger sensor triggers the controller to operate, halting the movement of the take-up roller and the propulsion member that have left the rewinding position. The controller then controls the take-up roller that has entered the rewinding position to operate. After a period of operation, the controller resets the propulsion member. This structure enables automated control of the winding drive assembly, reducing control workload and ensuring orderly operation.

[0006] It is further configured that: the propulsion member drives the propulsion roller to reciprocate toward the winding position and can be pressed against the propulsion roller, and the coil is transmitted between the propulsion roller and the winding roller located at the winding position.

[0007] By adopting the above technical solution, the propulsion component drives the propulsion roller to press against the receiving roller located in the winding position, and as the coiled material is transmitted between the propulsion roller and the new receiving roller, the two can clamp the transmitted coiled material, so that the coiled material can be conveniently wound on the new receiving roller that has entered the winding position after being cut, avoiding the problem of the coiled material falling after cutting, making the operation more convenient.

[0008] It is further configured that: when the pushing roller is in the second stroke, the pushing roller and the receiving roller located at the winding position are in tight contact with each other.

[0009] By adopting the above technical solution, the coiled material is kept from falling off, and has better practical functions.

[0010] It is further configured as follows: the propulsion component includes a first stroke component and a second stroke component, the movement path of the first stroke component intersects with the winding position, the first stroke component includes a propulsion frame slidably set on the frame and for installing the propulsion roller, a rack moving with the propulsion frame, a gear rotatably set on the frame and meshing with the rack, and a propulsion motor driving the gear to rotate.

[0011] By adopting the above technical solution, the propulsion motor drives the propulsion frame to move through the cooperation of the gear and the rack, thereby realizing the movement function of the first stroke.

[0012] It is further configured that: the movement path of the second stroke component intersects with the winding position, the second stroke component includes a stroke frame slidably arranged on the propulsion frame and a buffer cylinder connected to the stroke frame for driving the stroke frame to move toward the winding position, the propulsion roller is installed on the stroke frame, and the sensor corresponds to the movement path of the stroke frame and is located on the side of the stroke frame opposite to the winding position.

[0013] By adopting the above technical solution, the first stroke component drives the propulsion roller to press against the receiving roller. When entering the second stroke, the first stroke component continues to push the propulsion roller toward the receiving roller. The propulsion roller blocked by the receiving roller moves in opposite directions to compress the buffer cylinder and then trigger the sensor.

[0014] It is further configured as follows: a cutter assembly moving along with the travel frame is provided on the travel frame, and the cutter assembly is connected to a controller.

[0015] By adopting the above technical solution, when the winding roller at the winding position completes winding, the controller controls the cutter assembly to cut the coiled material, making the operation more convenient.

[0016] It is further configured that: the cutter assembly includes a cutter that is arranged on the travel frame and swings back and forth along the movement direction of the travel frame, and a driving cylinder that drives the cutter to move.

[0017] By adopting the above technical solution, the driving cylinder drives the cutter to swing toward one side of the coil, thereby completing the coil cutting function.

[0018] It is further configured as follows: the switching assembly includes two turntables rotatably arranged on the frame, a connecting roller connecting the two turntables, and a switching motor driving the turntable to move, and the receiving roller is installed on the turntable.

[0019] By adopting the above technical solution, the switching motor drives the turntable to rotate, thereby completing the position switching function of the receiving roller.

[0020] It is further configured as follows: the winding drive assembly includes a driven wheel rotatably set on the turntable and connected to the material receiving roller, a linkage wheel rotatably set at the center position of the turntable, a power motor, a driving wheel installed on the output shaft of the power motor, and a transmission belt connecting the driven wheel and the linkage wheel, and the linkage wheel and the driving wheel.

[0021] By adopting the above technical solution, the power motor drives the linkage wheel through the transmission belt, and the linkage wheel drives the driven wheel through the transmission belt to rotate, thereby completing the rotation drive function of the material roller. By positioning the linkage wheel at the center of the turntable, the existing winding drive assembly does not interfere with the normal rotation function of the turntable.

[0022] In summary, the present invention has the following beneficial effects: the present invention can realize automatic control of each winding drive component, thereby reducing the control workload and ensuring that the work is carried out in an orderly manner.
