[0002] Carton is a kind of paper packaging container, which is made of corrugated board through die cutting, indentation, nailing box or sticking box process.In the carton production process, it is often necessary to carry out flattening treatment, and the flattened carton is convenient for printing, die cutting, folding and other subsequent processing operations, and also facilitates stacking and stacking in the packaging process, improves packaging efficiency.

[0003] Roller flattening machine is usually used in the carton production process, and the existing roller flattening machine is mainly composed of a conveyor and an upper roller and a lower roller symmetrically installed on the conveyor.The unfolded carton is placed on the conveyor and transported, and the unfolded carton passes between the upper roller and the lower roller.The upper roller and the lower roller are driven to rotate by the driving device of the roller flattening machine, and the rotation directions are opposite, and then the unfolded carton is flattened by the upper roller and the lower roller.

[0004] However, the conventional roller flattening machine is not convenient to judge whether the flatness of the carton meets the standard after flattening the carton, for example, the installation position of the upper roller and the lower roller is not accurate or the upper roller and the lower roller are worn after long time use, which will cause the carton not to be completely flattened.If the carton is not flattened to the standard flatness, it will not only affect the appearance quality of the carton, making it not beautiful enough, but also affect the strength and stability of the carton.At the same time, the uneven carton may have problems such as inaccurate positioning, unclear printing pattern, irregular die cutting edge and smooth folding when performing subsequent processing operations such as printing, die cutting and folding.Therefore, we propose a kind of flat device for carton production.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a technical solution: such as Figure 1 - Figure 5 The flattening device for carton production shown includes a roller flattener body 1, a conveyor 2 fixedly installed at the rear end of the roller flattener body 1, the upper surface of the conveyor belt of the conveyor 2 being flush with the upper surface of the conveyor belt of the roller flattener body 1, and a flattening mechanism being provided on the conveyor 2.

[0024] The leveling mechanism includes a fixed plate 4, which is fixedly connected to one side wall of the conveyor 2. A stud 8 is rotatably connected to the upper end of the fixed plate 4. A connecting plate 9 is threaded onto the outer wall of the stud 8. A baffle 3 is rotatably connected to one end of the connecting plate 9. A guide is provided between the connecting plate 9 and the fixed plate 4. A support plate 11 is fixedly connected to the lower end of the connecting plate 9 near the baffle 3. The upper end of the support plate 11 is in contact with the lower end of the baffle 3. Electric suction cups 14 are symmetrically and movably inserted into the upper end of the baffle 3. A connecting mechanism is provided between the two electric suction cups 14 and the baffle 3. The baffle 3 is located above the conveyor 2.

[0025] The guide piece comprises a guide rod 6 fixedly connected to the upper end of the fixed plate 4, and the guide rod 6 movably penetrates the upper end of the connecting plate 9.

[0026] The connecting mechanism comprises two sockets 12 fixedly connected to the upper end of the baffle 3, and a cylinder 15 is slidably inserted into each of the sockets 12.

[0027] The upper end of the fixed plate 4 is fixedly connected to a rubber ring 7, and the inner wall of the rubber ring 7 is tightly attached to the lower edge of the outer wall of the stud 8.

[0028] The upper end of the stud 8 is fixedly connected to a rotating block 10, and a plurality of finger grooves are formed in the outer wall of the rotating block 10.

[0029] The upper end of the baffle 3 is symmetrically provided with two hole grooves 13, and the two electric suction cups 14 are respectively located in the two hole grooves 13.

[0030] Working principle: first, rotate the rotating block 10 to drive the stud 8 to rotate at the upper end of the fixed plate 4, and the stud 8 will drive the connecting plate 9, the supporting plate 11, the baffle 3 and other components connected to the baffle 3 to move downward. Figure 1 The distance between the lower end surface of the baffle 3 and the conveying belt of the conveyor 2 is adapted to the flatness of the carton, that is, the carton with flatness can just pass under the baffle 3 on the conveying belt of the conveyor 2. Then the unfolded carton is flattened, first, the unfolded carton is placed on the conveying belt of the roller flattening machine body 1, then the unfolded carton passes through the two compression rollers on the roller flattening machine body 1 and is flattened, which is a known prior art and will not be described in detail.

[0031] The flattened carton is conveyed by the conveyor 2, and the carton meeting the flatness requirement is just below the baffle 3, and the carton not meeting the flatness requirement, for example, the carton with a protruding part, is blocked by the protruding part below the baffle 3. At this time, the worker turns up the pressing plate 5 with one hand, and the pressing plate 5 drives the two cylinders 15, the two springs 16, the two sleeves 12, the two electric suction cups 14 and the baffle 3 to turn up. The baffle 3 turns on the connecting plate 9. At this time, the carton loses the restriction of the baffle 3 and continues to be conveyed forward until the middle position of the carton corresponds to the two electric suction cups 14. At this time, the pressing plate 5 is quickly turned down until the baffle 3 is attached to the upper end of the supporting plate 11, and the pressing plate 5 is quickly pressed down at this time. The pressing plate 5 drives the two cylinders 15 to slide down in the corresponding sleeves 12 and press the corresponding springs 16. The pressing plate 5 also drives the two electric suction cups 14 to move down in the corresponding hole slots 13 until the suction ports of the two electric suction cups 14 are pressed against the upper end surface of the carton and start the two electric suction cups 14. The two electric suction cups 14 can suck the carton. Finally, the pressing plate 5 is turned up to drive the baffle 3, the two electric suction cups 14 and the carton to turn up together. The carton quickly leaves the conveying belt of the conveyor 2. Then the two electric suction cups 14 are turned off and the carton is taken away. Then the pressing plate 5 is returned to its original position to continue to measure the flatness of the next carton.

[0032] It should be noted that according to the height adjustability of the baffle 3, the baffle 3 can measure the flatness of cartons of different thicknesses.

[0033] It should be further noted that the carton not meeting the flatness requirement and blocked by the baffle 3 can be quickly taken away, and the worker does not need to take the carton away from the conveying belt of the conveyor 2, avoiding the worker's hands being rubbed by the running conveying belt and being scratched.

[0034] It should be further noted that after the roller flattening machine body 1 flattens the carton, the worker can intuitively judge whether the flatness of the carton meets the standard, and it is convenient for the worker to take away the carton not meeting the flatness requirement for secondary flattening treatment on the roller flattening machine body 1, so that the final flatness of the carton meets the standard, thereby avoiding the carton not meeting the flatness requirement affecting the subsequent processing and appearance.
