Description
Technical Field
[0001] This utility model relates to the field of packaging machinery technology, specifically to a transmission structure suitable for carton production equipment that combines a square shaft with a sliding seat. Background Technology
[0002] The fully automatic box gluing machine's operation includes paper feeding, paper positioning, gluing, pressing, and output. The entire process is completed through the coordinated operation of a precise control system and actuators, achieving efficient and precise box sealing. A double-sheet gluing machine is specifically designed to glue two sheets of paper, A and B, together. The workpiece is transported via belt conveyor. After being transported to the gluing area, the two sheets are aligned, and then glue is applied to their side edges. Therefore, baffles are required in the double-sheet gluing machine to ensure alignment and correction. To match the continuous operation of the fully automatic gluing machine, the baffles operate intermittently, switching between blocking and releasing the workpiece alignment process by flipping the baffles.
[0003] In a double-plate gluing machine, there are typically four sets of baffles mounted on baffle seats. These seats are fitted with a rotating shaft, and a servo motor drives the rotating shaft and baffles to rotate at a set angle, thus switching the baffles' working states. During carton production, the baffle positions need to be adjusted for workpieces of different sizes. This requires the baffle seats to be able to move left and right along the rotating shaft while simultaneously restricting their circumferential rotation. This is particularly important for large-format gluing machines, where the large span of the rotating shaft places high demands on its rigidity. Furthermore, due to the wide adjustment range of the baffles, smooth movement during operation must be ensured. Therefore, innovative designs are needed for the baffle assembly and adjustment structure. Utility Model Content
[0004] This utility model provides a transmission structure that combines a square shaft with a sliding seat. The aim is to adjust the position of the baffle in a fully automatic gluing machine by innovatively designing the flip shaft, the sliding seat and their assembly structure, so as to meet the alignment and correction requirements of paper sheets of different sizes and ensure the continuous operation of the gluing machine.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A transmission structure for cooperating between a square shaft and a sliding seat includes a square shaft, a square shaft rotation drive mechanism, a sliding seat assembly, and a sliding seat assembly translation drive mechanism.
[0007] The square shaft is pivotally mounted on the fixed component of the gluing machine at both ends. A sliding seat assembly is installed on the square shaft, and the square shaft can rotate at a set angle under the drive of the square shaft rotation drive mechanism.
[0008] The sliding seat assembly includes a sliding block, a roller seat, rollers, and a baffle connecting seat. The sliding block has a square shaft through hole, in which the roller seat is rotatably mounted. The center of the roller seat has a through-groove. Roller shafts arranged laterally and longitudinally are installed in the cross groove, and rollers are mounted on the roller shafts. The rollers installed on the laterally and longitudinally mounted roller shafts form a clearance channel in the cross groove that matches the cross-sectional shape of the square shaft. The square shaft passes through the clearance channel. The baffle connecting seat is fixed to the roller seat and is connected to the upper baffle of the gluing machine through a separate crank-slider structure. The sliding seat assembly can move axially along the square shaft under the drive of the sliding seat assembly translation drive mechanism.
[0009] In the aforementioned transmission structure where the square shaft and the sliding seat cooperate, a bearing is provided between the square shaft through hole of the sliding block and the roller seat.
[0010] The aforementioned transmission structure in which the square shaft and the sliding seat cooperate, wherein the sliding seat translation drive mechanism includes a first motor, a first transmission assembly, and a lead screw and nut transmission assembly; the first motor is arranged on a fixed component of the gluing machine and drives the lead screw and nut transmission assembly to operate through the first transmission assembly; in the lead screw and nut transmission assembly, the lead screw is arranged parallel to the square shaft, and the nut in the lead screw and nut assembly is fixedly installed on the sliding block of the sliding seat assembly.
[0011] The aforementioned transmission structure in which the square shaft and sliding seat cooperate, wherein the square shaft rotation drive mechanism includes a second motor and a second transmission assembly; the second motor is arranged on the fixed part of the gluing machine equipment, and the second motor and the first motor are respectively located at both ends of the square shaft, and the second motor drives the square shaft to rotate through the second transmission assembly.
[0012] In the aforementioned transmission structure where the square shaft and the sliding seat cooperate, both the second motor and the first motor are servo motors, and both the second transmission component and the first transmission component adopt a gear and toothed belt cooperation mode.
[0013] The aforementioned transmission structure for the square shaft and sliding seat also includes a sliding seat translation guide mechanism. The sliding seat translation guide mechanism comprises two symmetrically arranged parts, with a guide rod and a guide sleeve in each part. The guide rod is located on the left and right sides of the square shaft, and the guide sleeve is fixedly assembled with the sliding block of the sliding seat assembly, with the guide sleeve fitted over the guide rod.
[0014] This utility model provides a transmission structure for the cooperation of a square shaft and a sliding seat, suitable for paper positioning and correction operations in fully automatic carton gluing machines. It designs the baffle flipping shaft as a square shaft structure, enhancing the rigidity and torsional resistance of the flipping shaft, making it more suitable for large-format carton gluing machines. Correspondingly, this utility model includes a sliding block, roller, roller seat, and baffle connecting seat in the sliding seat assembly. The carton gluing machine baffle is assembled with the roller seat via a separately provided crank-slider structure and baffle connecting seat. The roller seat, through the roller installed in its cross groove, forms a clearance channel matching the cross-sectional shape of the square shaft. This allows for adjustment of the baffle position by driving the sliding block to move axially along the square shaft via the translational drive mechanism of the sliding seat assembly. During this process, the rollers installed in the roller seat roll in contact with the outer wall of the square shaft, making the baffle position adjustment process smoother and more stable. The roller seat in this invention forms a structure between the clearance channel and the square shaft to prevent relative rotation. When the square shaft rotates under the drive of the square shaft rotation mechanism, the roller seat and baffle connecting seat rotate accordingly. A separate crank-slider structure drives the baffle of the gluing machine to flip, thereby switching between workpiece alignment blocking and release actions. Therefore, this invention, through innovative design of the flipping shaft, sliding seat, and their assembly structure, achieves the adjustment of the baffle position in a fully automatic gluing machine, meeting the alignment and correction requirements of paper sheets of different sizes and ensuring continuous operation of the gluing machine.
