Description

Technical Field

[0001] The utility model relates to the technical field of pasting packaging paper boxes, in particular to a pasting and flattening device for packaging paper boxes. Background Art

[0002] Paper packaging is the most widely used type of packaging in the industrial packaging industry. Cardboard boxes and cartons are the primary form of transport packaging, widely used for sales packaging of various products, including food, medicine, and electronics. During the production of packaging cartons, the finished box body must be glued and bonded to meet product production requirements.

[0003] Currently, automated gluing and pasting processes are performed on packaging carton production lines. However, ensuring the quality of pasting for each carton is difficult during machine operation, often leading to incomplete gluing of the carton edges. This ultimately causes warping of the edges or a small area of ​​bulging in the center, compromising the quality of the carton. To address this issue, we propose a packaging carton pasting and flattening device for secondary flattening of pasted cartons. Utility Model Content

[0004] The purpose of the embodiment of the utility model is to provide a packaging paper box pasting and flattening device, which solves the problem of incomplete pasting of the edges of the paper box when pasting the paper box with pasting equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A packaging paper box pasting and flattening device comprises a belt conveyor. A base is provided on a frame of the belt conveyor. A pressing mechanism is provided on the base. The pressing mechanism is connected to a driving mechanism.

[0007] Preferably, the pressing mechanism includes a fixing rod with one end fixed to the base, and two pressing plates are slidably connected to the fixing rod, and the two pressing plates are respectively arranged on both sides of the conveying belt of the belt conveyor.

[0009] Preferably, the number of the fixing rods is four, and the four fixing rods are distributed at the four diagonal corners of the pressure plate in a rectangular array.

[0010] Preferably, the driving mechanism includes two connecting plates fixedly connected to the support plate, and a rotating shaft is rotatably installed on the two connecting plates. A cam is fixedly connected to the two rotating shafts, and the outer peripheral walls of the two cams are in contact with the opposite sides of the two pressure plates respectively.

[0012] By means of the above technical solution, the present invention provides a packaging carton pasting and flattening device. It has at least the following beneficial effects:

[0013] (1) The packaging paper box pasting and flattening device is capable of pressing the packaging paper box conveyed on the belt conveyor by setting a pressing mechanism, thereby gluing the parts of the packaging paper box that are not completely pasted and flattening the raised parts, so that the sealing part of the packaging paper box is pasted more completely, avoiding the situation where the edge of the paper box is arched or warped, and improving the pasting quality of the packaging paper box.

[0014] (2) The packaging paper box pasting and flattening device can control the synchronous reverse movement of the two pressure plates by setting a driving device, thereby clamping the two sides of the packaging paper box and improving the tightness of the pasting of the packaging paper box; by setting a pressure plate in the internal cavity of the conveyor belt, it can provide support for the bottom of the packaging paper box, so that the force of the other pressure plate can act on the paper box to ensure the flattening effect.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-4 , a technical solution provided by the utility model:

[0023] A packaging carton pasting and flattening device, comprising a belt conveyor 1, such as Figure 1 As shown, a belt conveyor 1 comprises a frame and a conveyor belt, which is used to transport pasted packaging cartons. The frame of the belt conveyor 1 is provided with a base 2, which is provided with a pressing mechanism 3. The pressing mechanism 3 is connected to a drive mechanism 4. During use, the drive mechanism 4 drives the pressing mechanism 3 to press the packaging cartons on the conveyor belt, improving the adhesion.

[0024] Combine Figure 2 As shown, the pressing mechanism 3 includes a fixed rod 31 with one end fixed to the base 2. Two pressure plates 32 are slidably connected to the fixed rod 31. One pressure plate 32 is positioned above the conveyor belt, and the other pressure plate 32 is positioned in the cavity in the middle of the conveyor belt. Specifically, there are four fixed rods 31, distributed in a rectangular array at the four diagonal corners of the pressure plates 32 to improve the stability of the two pressure plates 32.

[0025] Furthermore, the pressing mechanism 3 also includes a support plate 33 fixed at one end to the base 2. The support plates 33 are provided in two groups, two in each group. Two fixing plates 34 are fixedly connected to each group of support plates 33. The opposite sides of the two fixing plates 34 are respectively connected to the two pressing plates 32 through springs 35. The spring 35 is sleeved on the outside of the fixing rod 31 to provide elastic force for the pressing plate 32, so that the pressing plate 32 can automatically reset under the elastic force after losing the external force restriction.

[0026] Combine Figure 2 and Figure 3 As shown, there are two driving mechanisms 4 , which are symmetrically arranged on both sides of the conveyor belt.

[0027] Each drive mechanism 4 includes two connecting plates 41 fixedly connected to the support plate 33. A rotating shaft 42 is rotatably mounted on each connecting plate 41. A cam 43 is fixedly connected to each rotating shaft 42. The outer peripheral walls of the two cams 43 contact the opposite sides of the two pressure plates 32. During the rotation of the cams 43, the pressure plates 32 can be pressed, causing the pressure plates 32 to move toward the conveyor belt, thereby pressing the packaging carton. Of the two pressure plates 32, the upper one can directly contact the packaging carton, and the lower one can contact the inner ring of the conveyor belt to provide support for the conveyor belt, so that the downward pressure of the pressure plate 32 can directly act on the carton, ensuring the flattening effect.

[0028] In addition, the driving mechanism 4 also includes a mounting base 44 fixedly connected to the support plate 33, a driving motor 45 is fixedly mounted on the mounting base 44, a driving wheel 46 is fixedly mounted on the output end of the driving motor 45, the distance between the driving wheel 46 and the two driven wheels 47 is equal, and the two rotating shafts 42 are fixedly mounted with driven wheels 47, the driving wheel 46 is connected to the two driven wheels 47 through a V-belt 48, and the two rotating shafts 42 are driven to rotate at the same time by the cooperation of the driving wheel 46 and the driven wheel 47, which can eliminate the time difference and angle difference between the movement of the two cams 43, thereby ensuring that the two pressure plates 32 can move at the same time, so that the flattening effect is better.

[0029] When the packaging box pasting and flattening device of the present invention is in use, the pasted packaging box is transported by a belt conveyor 1. During the transportation process, the driving motor 45 drives the driving wheel 46 to rotate, and the driving wheel 46 drives the two driven wheels 47 to rotate through the V-belt 48. The two driven wheels 47 simultaneously drive the two rotating shafts 42 to rotate, thereby causing the two cams 43 to rotate synchronously. During the rotation of the cam 43, the two pressure plates 32 are pressed toward one side of the packaging box, so that the distance between the two pressure plates 32 is shortened. Eventually, the upper pressure plate 32 will contact the packaging box, and the lower one can contact the inner ring of the conveyor belt to provide support for the bottom of the packaging box. Through the cooperation of the two pressure plates 32, the packaging box is flattened, so that the unpasted part of the packaging box is re-pasted.
