Description
Technical Field
[0001] The utility model relates to the technical field of packaging machinery, in particular to a pre-pressing and fine-pressing wheel integrated lifting and adjusting mechanism. Background Art
[0002] A carton forming machine is a processing device for packaging cartons. When processing cartons, it will press the surface of the cartons through wire wheels, so as to produce indentations on the surface of the cartons. When some thick cartons are being pressed, generally a set of pressing wheels composed of pre-pressing wheels and fine-pressing wheels is required to perform a secondary pressing operation on the cartons. First, the pre-pressing wheel gently presses a shallow mark on the surface of the carton, and then the fine-pressing wheel is used to press over the shallow mark, and finally the pressing work of the carton is completed. By performing the pressing operation in this way, it is possible to prevent the situation of cracking on the surface of the carton caused by direct pressing. Generally, multiple sets of pressing wheels are provided on the carton forming machine to meet the processing requirements of different indentation numbers. The set of pressing wheels can move left and right on the sliding rod of the carton forming machine. However, such a set of pressing wheels has certain deficiencies. For example, according to different pressing requirements, some cartons may be wider in size, but only one or two indentations need to be pressed on the surface of the carton. In the past, the forming machine would slide the redundant set of pressing wheels to one side of the forming machine and only use one or two sets of pressing wheels for the pressing work. Since the set of pressing wheels itself occupies a certain space inside the forming machine, even if all the redundant sets of pressing wheels are moved to one side of the forming machine, each set of pressing wheels arranged side by side still occupies a certain width in the forming machine. If the carton is too wide, there may be a situation of insufficient space in the existing carton forming machine, that is, when the carton is being conveyed on the conveyor belt of the forming machine, the edge of the carton will still pass by the set of pressing wheels parked on one side, so that the pressing work cannot be normally completed, bringing great inconvenience to the pressing work. Summary of the Utility Model
[0003] The purpose of the utility model is to avoid the deficiencies of the prior art and provide a pre-pressing and fine-pressing wheel integrated lifting and adjusting mechanism, so as to effectively solve the deficiencies existing in the prior art.

[0019] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0020] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.
[0021] As Figures 1-3 shown, the pre-pressing and fine-pressing wheel integrated lifting and adjusting mechanism in this embodiment includes a movable plate 1 that can move left and right on the frame of the carton forming machine. A vertical installation vertical plate 2 is provided at the bottom of the movable plate 1. Two swing plates 3 with opposite directions are provided on the front and rear sides of the installation vertical plate 2. The swing plates 3 are hinged to the installation vertical plate 2 and the swing plates 3 can rotate along the hinge axis. A pre-pressing wheel 4 and a fine-pressing wheel 5 are respectively provided at one end of the swing plates 3 far from the installation vertical plate 2. The pre-pressing wheel 4 and the fine-pressing wheel 5 are on the same horizontal line;
[0022] A guiding slide bar (not shown in the figure) is provided on the carton forming machine. A sliding seat is provided at the top of the movable plate 1, and the guiding slide bar penetrates through the sliding seat.
[0023] The swing plate 3 is driven to rotate by the adjusting cylinder 6. The piston rod of the adjusting cylinder 6 is arranged vertically downward. Installation rods 7 are arranged at both ends of the movable plate 1. The cylinder barrel of the adjusting cylinder 6 is hinged to the installation rod 7, and the piston rod of the adjusting cylinder 6 is vertically downward and hinged to one end of the swing plate 3 away from the installation vertical plate 2.
[0024] The front and rear swing plates 3 respectively extend towards the left and right sides of the installation vertical plate 2. A pre-pressing wheel 4 is arranged on the swing plate 3 extending towards the left, and a fine-pressing wheel 5 is arranged on the swing plate 3 extending towards the right.
[0025] A bracket 8 is further arranged at the top of the movable plate 1. A servo motor 9 is arranged on the bracket 8. A gear shaft 10 is arranged on the drive shaft of the servo motor 9. A rack (not shown in the figure) is also horizontally arranged on the frame of the carton forming machine. The gear shaft 10 meshes with the rack.
[0026] When the servo motor 9 starts, it can drive the gear shaft 10 to rotate. The rotating gear shaft 10 rotates along the rack, thereby controlling the movable plate 1 to move back and forth along the guiding slide rod.
[0027] The sliding seat includes a hollow slider 11 horizontally arranged at the top of the movable plate 1. Sliding components 12 are arranged at both ends of the slider 11. The sliding components 12 are arranged in a fitting manner with the side wall of the guiding slide rod.
[0028] The sliding component 12 includes a shaft rod 12a and a bearing 12b arranged on the shaft rod. A first receiving groove 11a for receiving the shaft rod 12a and a second receiving groove 11b for receiving the bearing 12b are arranged at the end of the slider 11. The two receiving grooves are interconnected. The combined sliding component 12 is placed in the two receiving grooves. The bearing 12b is arranged in a fitting manner with the side wall of the guiding slide rod.
[0029] Four sliding components 12 are arranged. The four sliding components 12 are arranged circumferentially at the end of the slider 11.
[0030] Pressing plates 13 are arranged at both ends of the slider 11. A first through hole for facilitating the passing of the guiding slide rod is arranged in the middle of the pressing plate 13. An avoidance notch 13a is arranged on the pressing plate 13 at the position corresponding to the bearing 12b.
[0031] A cover plate 14 is further arranged on the outer side of the pressing plate 13. A second through hole for facilitating the passing of the guiding slide rod is arranged in the middle of the cover plate 14. An oil injection hole 14a is arranged on the cover plate 14 at the position corresponding to the bearing 12b.
[0032] The cover plate 14 and the pressing plate 13 are fixed to the end of the slider 11 through a screw 15.
[0033] When the sliding seat is assembled, first, the bearing 12b is sleeved on the shaft rod 12a, and then the assembled sliding assembly 12 is placed in the receiving groove at the end of the slider 11. The bearing 12b can rotate in the second receiving groove 11b. Then, the pressing plate 13 is pressed on the end of the slider 11. The avoiding notch 13a on the pressing plate 13 corresponds to the position of the bearing 12b, so as to prevent it from restricting the rotation of the bearing 12b. And other positions of the pressing plate 13 can block the first receiving groove 11a, so as to limit the shaft rod 12a. Finally, the cover plate 14 is covered on the outside of the pressing plate 13, and the screw 15 sequentially passes through the cover plate 14 and the pressing plate 13 and is finally screwed to the end of the slider 11. In this way, the installation work is completed. After the installation is completed, the bearing 12b extends into the through hole of the slider 11, so as to ensure that the bearing 12b can be attached to the side wall of the guiding slide rod. In this way, when the movable plate 1 moves, the sliding seat and the guiding slide rod are in rolling friction, so as to reduce the friction generated during the movement, ensure that the movable plate 1 can slide smoothly, and avoid jamming. And the setting of the oil injection hole 14a on the cover plate 14 facilitates the staff to inject lubricating oil into the sliding assembly 12 in the sliding seat, so as to improve the sliding smoothness.
[0034] The working principle of the present utility model is as follows: A guiding slide rod is horizontally arranged on the frame of the carton forming machine. Multiple groups of movable plates 1 and their supporting swing plates 3, as well as pre-pressing and fine-pressing wheels, are arranged on the guiding slide rod. According to the requirements of the carton board creasing processing, the required number of pre-pressing and fine-pressing wheels is selected, and by controlling the rotation of the servo motor 9, the required respective pressing wheels are controlled to move to the creasing position. For the other unnecessary pressing wheels, the working of the adjusting cylinders 6 thereon can be controlled. At this time, the piston rods of these adjusting cylinders 6 retract, so that the swing plate 3 rotates upward along the hinge shaft. Since the position of the swing plate 3 changes, at this time, the positions of the pre-pressing wheel 4 and the fine-pressing wheel 5 will also rise, so as to increase the gap between the two pressing wheels and the conveying belt. In this way, when the carton is conveyed and creased, the unused pre-pressing wheel 4 and fine-pressing wheel 5 will not contact the carton board, and the normally working pre-pressing wheel 4 and fine-pressing wheel 5 can normally crease the carton. The whole adjusting process does not need to move the positions of the unused pre-pressing and fine-pressing wheels. Only by controlling the adjusting cylinder 6 to raise the unnecessary pre-pressing and fine-pressing wheels, the creasing work can be normally carried out. In this way, not only the adjusting efficiency is reduced, but also the creasing work of various wide cartons can be adapted, and the adaptability of the carton forming machine is greatly improved.
[0035] The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.
