Description

Technical Field

[0001] The utility model belongs to the technical field of carton processing, and particularly relates to a carton flattening device. Background Art

[0002] During the production process of cartons, glue needs to be applied to the corners or overlapping parts of the cartons so that the ends of the cartons can be connected together to ensure the stability and strength of the cartons during use. Generally, after gluing, the cartons need to be flattened on a conveyor belt and squeezed with rollers so that the gel can better adhere to the carton and reduce the probability of detachment.

[0003] The existing flattening equipment for cartons is usually divided into conveyor belt extrusion or vertical platen extrusion. Since the cartons are in a folded state and the thickness of the cartons is different, it is necessary to adjust the extrusion space of the cartons. However, the adjustment structure on the current equipment is relatively complicated, which is troublesome to operate and has poor stability. It is not easy to adapt to cartons of different thicknesses and widths. Over-pressure or under-pressure is prone to occur during the flattening process, which greatly reduces the flattening effect of the carton. Utility Model Content

[0004] The purpose of the utility model is to provide a carton flattening device, which can adjust the space of the pressing roller and the extension distance of the movable wheels on both sides according to the thickness and width of the carton, so as to improve the flattening effect on the carton.

[0020] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0021] like Figure 1-4As shown, a carton flattening device comprises two mounting plates 1, a conveyor belt 3 is installed between the two mounting plates 1, two round rollers are rotatably connected to the inner side of the conveyor belt 3 between the mounting plates 1, a bracket 2 is fixedly connected to the bottom surface of the mounting plate 1, a fixing plate 4 is fixedly connected to the top surface of the mounting plate 1, the fixing plate 4 is U-shaped, a support plate 5 is arranged on the inner side of the fixing plate 4, two connecting plates 6 are arranged on the lower side of the supporting plate 5, a pressing roller 7 is rotatably connected to the side wall of the connecting plate 6, the left connecting plate 6 is fixedly connected to the support plate 5, an elastic component is arranged on the top surface of the right connecting plate 6, an adjusting component is arranged on the top surface of the fixing plate 4, and a limiting component is arranged on the top surface of the mounting plate 1 near the left side.

[0022] like Figure 2 and Figure 3 As shown, the elastic component includes a round rod 10 fixedly connected to the top surface of the connecting plate 6, the top end of the round rod 10 passes through the support plate 5 and is movably connected thereto, a baffle 11 is fixedly connected to the top end of the round rod 10, and a spring 12 is sleeved on the side wall of the round rod 10 located between the support plate 5 and the baffle 11.

[0023] Specifically, when the carton passes through the left pressure roller 7 and then enters the right pressure roller 7, and the left pressure roller 7 is a fixed pressure, the carton is initially flattened, and the right pressure roller 7 is an elastic pressure. After the carton passes through the right pressure roller 7, the force of the spring 12 is used to assist in flattening the carton, thereby ensuring the flattening effect of the carton and reducing the phenomenon of over-pressure or under-pressure of the carton.

[0024] like Figure 2 As shown, the adjustment assembly includes a screw rod 8 threadedly connected to the top surface of the fixed plate 4, a rotating wheel 9 is fixedly connected to the top of the screw rod 8, and the bottom of the screw rod 8 is rotatably connected to the support plate 5. By rotating the rotating wheel 9, the screw rod 8 can be rotated up and down, so that the support plate 5 drives the pressure roller 7 to move downward to a suitable position.

[0025] Among them, the adjustment component has the characteristics of simple structure, convenient operation, good stability, etc., and is highly practical in actual use. At the same time, the structure is an existing mature mechanism, so it will not be described in detail in this solution.

[0026] like Figure 4 As shown, the limiting assembly includes a support plate 13 fixedly connected to the top surface of the mounting plate 1, a through hole is provided on the side wall of the support plate 13, a movable rod 14 is provided in the through hole, and a movable wheel 15 is rotatably connected to the end of the movable rod 14 close to the conveyor belt 3. A bolt 16 is threadedly connected to the top surface of the support plate 13, and a limiting groove 17 is provided on the side wall of the movable rod 14, and the bolt 16 abuts against the limiting groove 17. The cross section of the movable wheel 15 is stepped.

[0027] By setting the limit assembly, the distance between the movable wheels 15 on both sides can be adjusted to facilitate adapting to cartons of different widths and ensure that the carton is in the correct position to enter the lower side of the pressing roller 7.

[0028] The working principle of the utility model is as follows: firstly, the spacing between the movable wheels 15 on both sides is adjusted according to the width of the carton, and the bolt 16 is first turned to release the fixation of the movable rod 14, and then the movable rod 14 is moved to drive the movable wheel 15 to reach a suitable distance, and then the bolt 16 is tightened to fix the movable wheel 15, and then the rotating wheel 9 is turned to drive the screw 8 to rotate, and the screw 8 drives the pressure roller 7 to move downward to a suitable position through the support plate 5, and then the carton is placed on the conveyor belt 3, and the conveyor belt 3 is started. The carton is positioned in contact with the movable wheels 15 on both sides as it is transported by the conveyor belt 3, and the carton is flattened when it passes through the pressure roller 7, and at the same time, the action force of the spring 12 is used to drive the right pressure roller 7 to move downward to assist in flattening the carton, thereby ensuring the flattening effect of the carton.

[0029] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
