Description

Technical Field

[0001] The utility model relates to a printing press, in particular to a turret material collecting and unloading mechanism. Background Art

[0002] A printing press includes a rewinding mechanism and a discharging mechanism. Since the two mechanisms operate on similar principles—one unwinds the printed material, the other winds it—their mechanical structures are also nearly identical. To avoid wasted time loading and unloading the printed material, existing rewinding and discharging mechanisms incorporate an alternating mechanism to compensate for the time lost during loading and unloading. To improve loading and unloading efficiency, existing commercially available loading and unloading mechanisms also replace manual loading and unloading. The present utility model was designed to integrate these structures and mechanize the process. Utility Model Content

[0003] The purpose of the utility model is to provide a turret material collecting and unloading mechanism, which can realize alternating material collecting and unloading simultaneously while mechanically realizing loading and unloading of materials, thereby realizing the mechanization of the process and improving the production efficiency of the equipment to the greatest extent.

[0004] The above technical purpose of the present utility model is achieved through the following technical solutions: a turret material collecting and unloading mechanism, comprising: a frame; material rollers, which are provided in at least two numbers and are located on the frame for mounting the printing material; an alternating conversion component, which is provided to drive each material roller to switch between a working position and a loading and unloading position; a detachable fixing component, which is provided between each material roller and the alternating conversion component to achieve detachable fixation of the two; a lifting and loading and unloading component, which is provided to drive the material roller to switch between the loading and unloading position and a falling position close to the ground.

[0005] By adopting the above technical solution, the printing material is installed on the material roller and is switched between the working position and the loading and unloading position under the action of the alternating conversion component. When the printing material on one of the material rollers completes the processing work at the working position, the material roller is switched to the loading and unloading position, and then the printing material on the other material roller is switched from the loading and unloading position to the working position, thereby realizing the alternating storage and release of the printing material, avoiding the time wasted due to loading and unloading operations. The printing material on the material roller at the loading and unloading position is separated from the alternating conversion component by a detachable fixing component. After separation, it is lifted and lowered by the provided lifting and unloading component so that it can fall to the ground, thereby realizing mechanized loading and unloading operations. The above-mentioned setting structure realizes the mechanization of the process and maximizes the production efficiency of the equipment.

[0006] It is further configured to include: at least two groups of power components, which are configured to correspond to the material rollers one by one and drive the corresponding material rollers to rotate; a linkage structure, which is configured to constitute a linkage between the power components and the material rollers and has a linkage state and a separation state. When the material roller is in the working position, the power component drives the material roller to rotate through the linkage structure.

[0007] By adopting the above technical solution, the power component transmits power to the material roller through the linkage structure to drive the material roller to rotate, so that the material roller can meet the practical needs of more different working conditions and uses, making it more practical.

[0008] It is further configured as follows: the alternating conversion component includes two turntables, an installation area formed between the two turntables and where a feed roller is installed, a connecting roller connecting the two turntables, and an alternating drive member for driving one of the turntables to rotate.

[0009] By adopting the above technical solution, the material roller is installed between the two turntables, and the turntables are driven to rotate by alternating driving members to drive the material roller to switch between the working position and the unloading position.

[0010] It is further configured as follows: the detachable fixing component is arranged between the end of the material roller and the alternating conversion component, the alternating conversion component includes a fixed buckle arranged on the alternating conversion component and having a lateral opening, a movable buckle hinged to the fixed buckle and used to fasten the opening of the fixed buckle, and a locking structure that drives the movable buckle to fasten the fixed buckle, and the material roller is arranged between the fixed buckle and the movable buckle.

[0011] By adopting the above technical solution, the end of the material roller is installed between the fixed buckle and the movable buckle through the opening formed in the fixed buckle, and then the movable buckle is fastened and locked with the provided locking structure, thereby achieving the purpose of detachable fixation of the material roller.

[0012] It is further configured as follows: the lifting and loading and unloading assembly includes two supporting arms slidably arranged on the frame and corresponding to the two ends of the material roller, and a lifting structure that drives the two supporting arms to move, and the loading and unloading position is located above the supporting arm movement path and intersects with it.

[0013] By adopting the above technical solution, the lifting structure drives the supporting arm to move to the loading and unloading position, and then the detachable fixing component is disassembled to transfer the material roller to the top of the supporting arm to realize the lifting movement of the material roller.

[0014] It is further configured as follows: the lifting structure is configured as two and corresponds to two supporting arms respectively, the lifting structure includes two chain plates rotatably arranged on the frame, a lifting chain connecting the two chain plates, and a lifting motor driving one of the chain plates to rotate, and the lifting chain is connected to the supporting arm.

[0015] By adopting the above technical solution, the lifting motor drives the lifting chain and the supporting arm to perform lifting movements through the chain plate.

[0016] It is further configured as follows: the power assembly includes a driven wheel rotatably set on the turntable and connected to the material 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.

[0017] 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 self-rotation drive function of the material roller. By positioning the linkage wheel at the center of the turntable, the existing power component does not interfere with the normal rotation function of the turntable.

[0018] It is further configured that: the linkage structure includes a linkage groove and a linkage block inserted into the linkage groove to form a linkage between the material roller and the driven wheel, and the detachable fixing component fixes the linkage structure in a linkage state.

[0019] By adopting the above technical solution, the linkage groove and the linkage block cooperate to achieve the purpose of detachable linkage.

[0020] It is further configured as follows: the locking structure includes a movable bolt connected to the fixing buckle and a locking handle threadedly connected to the movable bolt for driving the movable buckle to buckle the fixing buckle.

[0021] By adopting the above technical solution, the locking handle cooperates with the swing bolt to achieve the locking purpose.

[0022] In summary, the present invention has the following beneficial effects: the present invention can realize alternating material collection and discharge simultaneously while mechanically realizing loading and unloading of materials, thereby realizing the mechanization of the process and improving the production efficiency of the equipment to the greatest extent.
