Technical Field

[0001] This utility model relates to the field of packaging box equipment technology, and in particular to an online pressure-holding device for cardboard in folding boxes. Background Technology

[0002] Folding boxes are packaging boxes made of folded cardboard. Currently, some folding boxes are made by gluing the cardboard pieces together and using a pressure-holding device to press the cardboard together to ensure the adhesion of the glue. However, the existing pressure-holding devices are located on one side of the production line, requiring operators to manually pick up the cardboard pieces to be pressed from the production line and put them into the pressure-holding device. This process is inefficient and time-consuming. Utility Model Content

[0013] The technical solution provided by this utility model has the following beneficial effects:

[0014] During the cardboard pressure holding process, the cardboard is first transported to the pressure holding position via the conveyor belt. Then, the pressure holding assembly is lowered by the lifting driver until the pressure plate presses against the cardboard on the conveyor belt. After that, the traverse driver drives the pressure plate to move synchronously with the conveyor belt to ensure that the pressure plate is always pressed against the cardboard on the conveyor belt. This allows for online pressure holding operations that follow the cardboard on the conveyor belt, replacing manual pressure holding operations, saving time and labor, and improving work efficiency.

[0017] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] Reference Figure 1 and Figure 2 As shown, this embodiment provides an online pressure-holding device for folding box cardboard (hereinafter referred to as pressure-holding device) to perform pressure-holding operations on the cardboard of the folding box, and after pressure holding, to ensure that the glue between the cardboards has a good bonding effect.

[0020] The pressure-holding device in this embodiment includes a conveyor belt 1 for conveying cardboard and a pressure-holding mechanism 2 disposed above the conveyor belt 1. The conveying direction of the conveyor belt 1 is defined as the front and rear directions, and the conveying direction perpendicular to the conveyor belt 1 is defined as the left and right directions.

[0021] The pressure holding mechanism 2 includes a pressure holding component 21, a lifting driver 22, and a guide rail 23 mounted on the lifting end of the lifting driver 22. The pressure holding component 21 includes a transverse driver 211 and two integrally connected pressure plates 212. The lifting driver 22 is a lifting cylinder, and the transverse driver 211 is a pen-shaped cylinder.

[0022] The transverse drive 211 is fixed to the guide rail 23 by the first fixed connector, and the two pressure plates 212 are slidably assembled on the guide rail 23, and the extension direction of the guide rail 23 is parallel to the conveying direction of the conveyor belt 1.

[0023] During pressure holding, the transverse drive 211 drives the connected pressure plate 212 to move forward and backward synchronously with the conveyor belt 1. The pressure plate 212 is used to press the cardboard on the conveyor belt 1.

[0024] In this embodiment, the guide rail 23 is fixed to the lifting end of the lifting driver 22 by the second fixed connector.

[0025] A U-shaped crossbeam 3 is provided above the conveyor belt 1. The left and right ends of the crossbeam 3 are respectively mounted on the frame of the conveyor belt 1. A sensor 4 is mounted on the crossbeam 3 to sense whether the cardboard on the conveyor belt 1 has been conveyed to its pressure holding position. The extension direction of the crossbeam 3 is perpendicular to the conveying direction of the conveyor belt 1. The pressure holding mechanism 2 is fixedly connected to the center of the crossbeam 3 and suspended above the conveyor belt 1. The extension directions of the two pressure plates 212 are perpendicular to the conveying direction of the conveyor belt 1.

[0026] The pressure holding assembly 21 also includes a connecting rod 213 and four sliders 214. One pressure plate 212 corresponds to two sliders 214, and each pair of sliders 214 is slidably mounted on the left and right sides of the guide rail 23.

[0027] Each pressure plate 212 is connected to two sliders 214, and one end of the connecting rod 213 passes through the two sliders 214 on the same side. The other end of the connecting rod 213 is connected to the telescopic end of the transverse drive 211. At this time, the pressure plate 212, sliders 214, connecting rod 213 and the telescopic end of the transverse drive 211 are connected to form a synchronously moving pressure plate assembly. Under the drive of the transverse drive 211, the pressure plate assembly moves back and forth along the guide direction of the guide rail 23. The movement speed of the pressure plate assembly matches the conveying speed of the conveyor belt 1 to ensure that the pressure plate 212 is always pressed against the cardboard on the conveyor belt 1 during pressure holding.

[0028] After the cardboard pressure holding is completed, the lifting end of the lifting driver 22 and the telescopic end of the transverse driver 211 are reset to facilitate the pressure holding operation of the next cardboard.

[0029] The pressure holding device in this embodiment also includes a main control system. The input end of the pressure holding mechanism 2 is connected to the output end of the main control system, and the input end of the main control system is connected to the output end of the sensor 4. At this time, the sensor 4 controls the various actions of the pressure holding mechanism 2 through the main control system to complete the online follow-up pressure holding operation.

[0030] During the cardboard pressure holding process, the cardboard is first transported to the pressure holding position via the conveyor belt 1. Then, the pressure holding component 21 is lowered via the lifting driver 22 until the pressure plate 212 presses the cardboard on the conveyor belt 1. After that, the lateral drive 211 drives the pressure plate 212 to move synchronously with the conveyor belt 1 to ensure that the pressure plate 212 is always pressed against the cardboard on the conveyor belt 1. This enables online pressure holding operations to follow the cardboard on the conveyor belt 1, replacing manual pressure holding operations, saving time and effort, and improving work efficiency.

[0031] Of course, in other embodiments, the pressure holding mechanism 2 can also be fixed to the left or right side of the crossbeam 3 according to the actual needs of the site.

[0032] The pressure holding mechanism 2 can also be slidably connected to the crossbeam 3 and equipped with a transverse drive assembly to adjust the left and right positions of the pressure holding mechanism 2 on the crossbeam 3.

[0033] Alternatively, the lifting drive 22 and the traverse drive 211 can also be motor drive assemblies containing transmission rods.

[0034] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
