Description

Technical Field

[0001] The utility model relates to the field of labeling machines, in particular to a flipping and steering device for a double-sided labeling machine. Background Art

[0002] The labeling machine is an automated device that is mainly used to attach labels to the surface of a product or package. It is widely used in many industries such as food, beverages, medicine, cosmetics, and electronic products to achieve product identification, tracking, and management. Existing double-sided labeling machines all need to label vertical bottles, but for some flat products (such as books, cardboard, flat packaging bags, etc.), one of the front and back sides is in contact with the conveyor belt, resulting in the need to manually flip the flat product after one side is labeled and then label it again, which makes the entire equipment time-consuming and labor-intensive, and inefficient. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a flipping and steering device for a double-sided labeling machine in view of the deficiencies of the above-mentioned prior art.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flip and steering device for a double-sided labeling machine, comprising a frame and a plurality of conveyor belts arranged on the frame for conveying materials, the frame is provided with a flip assembly, the flip assembly comprises a plurality of flip disks and a flip motor driving the flip disks to rotate intermittently, the flip disk is provided with at least one flip notch for materials to enter and flip to the other side, the flip disk passes through the conveyor belt, and when the flip notch faces the material conveying direction, the flip notch is flush with the conveyor belt.

[0005] With the above technical solution, the flipping and steering devices will be respectively arranged in the middle of the double-sided labeling machine, and a labeling machine will be connected to each of the two ends. After the flat product is labeled on the front side at the labeling machine at the front end, it enters the flipping assembly along the conveyor belt, and then enters the flipping gap of the flipping disk. After being flipped 180° by the flipping motor, it reaches the other side of the flipping disk. In this way, the unlabeled side on the back side will be automatically flipped to the outside through the flipping disk, and then advanced to the labeling machine at the rear end via the conveyor belt for re-labeling. The intermittently rotating flipping motor cooperates with the conveyor belt to ensure that only one material will be flipped in a single flipping gap. No manual intervention is required, thereby realizing automatic front and back labeling and improving stability and processing efficiency.

[0006] Furthermore, a flip drive hole connected to the output end of the flip motor is provided at the center of the flip disk, and four flip notches are distributed equidistantly around the flip drive hole as the center of the circle. The flip disk rotates with the gap of the flip motor, and when stopped, there are two corresponding flip notches arranged parallel to the conveyor belt.

[0007] By adopting the above technical solution, a flip drive hole is provided in the center of the flip disk, which is connected to the output end of the flip motor. The flip disk has four flip notches equidistantly distributed around the flip drive hole, so as to achieve accurate alignment during intermittent rotation and rest, realize continuous material flipping, reduce the flip waiting time, ensure the stability and uniformity of the flip disk during the rotation process, ensure the accuracy of each flipping action, and improve efficiency.

[0008] Furthermore, a plurality of weight-reducing holes are provided between the corresponding adjacent turning notches of the turning disc, and the weight-reducing holes are correspondingly distributed around the turning disc.

[0009] By adopting the above technical solution, weight-reducing holes are set between the adjacent flip notches corresponding to the flip disc. The weight of the flip disc is reduced through the design of the weight-reducing holes, the flexibility of the flipping action is improved, the weight is evenly balanced, the weight of the flip disc is reduced, the flipping efficiency is improved, and the energy consumption and cost are reduced.

[0010] Furthermore, the number of the flip disks is 3 and they are evenly distributed between adjacent conveyor belts, and the output end of the flip motor is provided with a synchronous flip shaft that passes through a flip driving hole in the center of the flip disk.

[0011] By adopting the above technical solution, the number of flip disks is 3, which are equidistantly distributed between adjacent conveyor belts. The synchronous rotation of the flip disks is achieved through the synchronous flip axis, avoiding the weight problem caused by the excessively wide flip gap when a single flip disk is used. In addition, the number of flip disks can be easily adjusted according to different labeled materials to improve adaptability and stability.

[0012] Furthermore, the frame is also provided with a steering assembly, which includes a bogie arranged above the frame, a steering drive arranged on the bogie, and a lifting cylinder arranged below the frame and corresponding to the steering drive. A steering wheel is provided at the output end of the steering drive, and a lifting plate is provided at the output end of the lifting cylinder. The lifting cylinder drives the material on the lifting plate to move closer to and away from the steering wheel, and cooperates with the steering wheel to steer the material on the lifting plate.

[0013] By adopting the above technical scheme, the material can be labeled on the front side first and then turned and flipped, or it can be flipped first and then turned. By setting the steering component, the material after being labeled on the front side can be pushed away from the conveyor belt by the lifting plate and then turn against the steering wheel, thereby controlling the material to complete the turning. The turned material can be turned or the flipped material can be turned to the subsequent labeling machine after the original front labeling position, thereby ensuring that the positions of the front and rear labels correspond to each other on the front and back sides, meeting the customer's labeling needs and making it more beautiful.

[0014] Furthermore, a positioning and blocking assembly is provided at one end of the frame corresponding to the steering assembly, and the positioning and blocking assembly includes a positioning cylinder arranged behind the steering assembly along the material conveying direction, and a plurality of blocking needles are provided at the output end of the positioning cylinder, and the positioning cylinder drives the blocking needles to pass through or retract into the conveyor belt plane of the frame.

[0015] The above technical solution is adopted to set up a positioning and blocking component, including a positioning cylinder and a blocking needle. The positioning cylinder drives the blocking needle to penetrate or retract, so as to realize the positioning of the material on the conveyor belt plane, thereby ensuring that the material will be blocked by the blocking needle raised out of the frame after passing through the lifting plate, so that the center of the material can be on the lifting plate, ensuring that the material can rotate with the center point as the center of the circle when turning, ensuring that the material can be in the same designated position after each turn, and ensuring the precise positioning of subsequent labeling.

[0016] Furthermore, a positioning adjustment groove is provided at the frame corresponding to the positioning blocking assembly, and the positioning adjustment groove is arranged in a long groove shape along the material conveying direction. The blocking needle penetrates into or retracts into the positioning adjustment groove with the positioning cylinder. A positioning adjustment guide roller is provided along the positioning adjustment groove at the bottom of the frame, and the positioning cylinder approaches or moves away from the steering assembly along the positioning adjustment guide roller.

[0017] By adopting the above technical solution, a positioning adjustment groove and a positioning adjustment guide roller are set, and the movement of the blocking needle in the positioning adjustment groove is used to achieve fine adjustment of the material positioning, and then the position of the center point can be adjusted according to the material of different specifications (length, width).

[0018] Furthermore, the steering drive component is a motor or a rotary cylinder.

[0019] By adopting the above technical solution, the steering drive member can be a motor or a rotary cylinder, and a suitable driving mode is selected according to actual needs to realize the steering action.
