Description

Technical Field

[0001] This application relates to the field of round paper drum manufacturing technology, and in particular to a novel round paper drum clamping device. Background Technology

[0002] In the production of round paper drums, the hoop-fitting process is generally done manually. First, the hoop is manually slipped onto the paper drum, flush with the opening; this is called hoop fitting. Then, a ring of glue is brushed onto the drum body below the hoop. Finally, a drum lid or a similar mold is used to press it into place; this is called pressing the hoop. Because this process involves three steps, workers need to move the drum at least three times for each drum, and the production technology is outdated and very inefficient.

[0003] For example, Chinese patent application number CN201210095239.2 discloses an automatic external clamping device for round paper drums. The worktable is mounted on the machine base via a rotary support, and the rotary support is connected to the power device of the worktable. The worktable is provided with upper and lower drum stations, glue spraying station, and clamping station. Each station on the worktable is provided with a bowl-shaped plate. Next to the glue spraying station is a paper drum rotation power device that drives the bowl-shaped plate on the glue spraying station to rotate via a transmission wheel. The clamping station is provided with a clamping device.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0005] The height of the clamping device in common automatic external clamping equipment for round paper drums is not adjustable. Therefore, when producing different round paper drums with large height differences, multiple sets of equipment need to be customized, which is not only inconvenient to operate, but also not conducive to saving equipment costs. Utility Model Content

[0006] This application provides a novel clamping device for round paper drums to improve the following technical problems:

[0007] The height of the clamping device in common automatic external clamping equipment for round paper drums is not adjustable. Therefore, when producing different round paper drums with large height differences, multiple sets of equipment need to be customized, which is not only inconvenient to operate, but also not conducive to saving equipment costs.

[0008] This application provides a novel clamping device for round paper drums, employing the following technical solution:

[0009] A novel round paper drum clamping device includes a base and a turntable horizontally rotatably mounted on the base. The base also has a power mechanism for intermittently rotating the turntable. Three fixed discs are symmetrically arranged around the turntable's central axis. These fixed discs are used for inserting the bottom of the round paper drum. The rotation axes of both the fixed discs and the turntable are vertically arranged. The three fixed discs are located at the loading / unloading station, the glue spraying station, and the clamping station, respectively. A portal frame is provided on the base, and vertical sliding is possible within the portal frame. Equipped with a crossbeam, the base is also provided with a glue spraying mechanism for applying glue to the outer peripheral wall of the circular paper drum at the glue spraying station. The crossbeam is provided with a pre-pressing mechanism, a clamping mechanism, and a lifting power unit. The pre-pressing mechanism is located directly above the glue spraying station and is used to press the clamping ring at the top of the circular paper drum downwards. The clamping mechanism is located directly above the clamping station and is used to press the clamping ring downwards along the outer peripheral wall of the circular paper drum to the position where glue is applied. The lifting power unit is used to drive the crossbeam to rise and fall relative to the portal frame.

[0010] In one feasible technical solution of this application, the lifting power unit includes a servo motor, a steering reduction gearbox, two transmission screws, and two sets of gear rack structures. The gear rack structures are respectively installed on opposite sides of the gantry frame. The outer ends of the transmission screws are connected to the gears of the gear rack structures, and the inner ends of the two transmission screws are respectively connected to the two output ends of the steering reduction gearbox. The servo motor is fixed on the crossbeam, and the output shaft of the servo motor is connected to the input end of the steering reduction gearbox.

[0011] In one feasible technical solution of this application, the middle part of the crossbeam is provided with a mounting hole adapted to the servo motor, and the pre-pressing mechanism and the clamping mechanism are respectively located on opposite sides of the mounting hole.

[0012] In one feasible technical solution of this application, the pre-compression flattening mechanism includes a pre-compression cylinder and a pre-compression circular plate. The pre-compression cylinder is vertically installed on the crossbeam, and the telescopic rod of the pre-compression cylinder extends from the bottom of the crossbeam. The pre-compression circular plate is horizontally arranged and fixed to the bottom of the telescopic rod of the pre-compression cylinder.

[0013] In one feasible technical solution of this application, the pre-pressing flattening mechanism further includes two sets of first guide rods and a first sliding sleeve. The bottom of the first guide rod is fixed to the pre-pressing circular plate, the first sliding sleeve is fixed to the crossbeam, and the first guide rod vertically penetrates the first sliding sleeve.

[0014] In one feasible technical solution of this application, the clamping mechanism includes a clamping mold and a clamping cylinder. The clamping cylinder is vertically installed on the crossbeam, and the telescopic rod of the clamping cylinder extends from the bottom of the crossbeam. The clamping mold is horizontally arranged and fixed to the bottom of the telescopic rod of the clamping cylinder.

[0015] In one feasible technical solution of this application, the clamping mechanism further includes two sets of second guide rods and a second sliding sleeve. The bottom of the second guide rod is fixed to the clamping mold, the second sliding sleeve is fixed to the crossbeam, and the second guide rod vertically penetrates the second sliding sleeve.

[0016] In one feasible technical solution of this application, the power mechanism includes a power motor, a power gear, and a linkage gear ring. The power motor is mounted on the base, the linkage gear ring is fixed to the lower surface of the turntable and the two are arranged concentrically, the power gear is connected to the output shaft of the power motor, and the power gear meshes with the external teeth of the linkage gear ring for transmission.

[0018] In one feasible technical solution of this application, the top of the portal frame is provided with a hollow hole, which is used for the top of the pre-pressing mechanism, the clamping mechanism and the lifting power unit to extend out.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] Workers can first place the hoop on the top of the outer wall of the round paper drum, then place it on the loading and unloading station, start the power mechanism to drive the turntable to rotate vertically, and then the round paper drum is transported to the glue spraying station. After the glue spraying device is started, glue can be sprayed on the outer wall of the round paper drum (located below the hoop). Then the power mechanism is started again to drive the turntable to rotate vertically, and the round paper drum is transported to the clamping station. The clamping mechanism is started to press the hoop at the top down to the glue position for bonding. Finally, the power mechanism is started again to drive the turntable to rotate vertically, and the clamped round paper drum is transported to the loading and unloading station, making it convenient for workers to remove the round paper drum and put in a new set of round paper drums.

[0021] When producing round paper drums of different heights, the lifting power unit can be activated to drive the crossbeam to rise or fall. This allows the limit pressing positions of the pre-pressing mechanism and the clamping mechanism to be automatically adjusted according to requirements, resulting in higher adaptability. It eliminates the need for customizing multiple sets of equipment, reducing operational inconvenience and saving equipment costs. Attached Figure Description
