Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, and in particular to a folding mechanism for cardboard box processing. Background Technology

[0002] Cardboard box processing refers to the process of processing and handling cardboard or cardboard boxes to adapt them to specific packaging needs or meet specific functional requirements. Cardboard box processing is usually completed at different stages of the cardboard box manufacturing process, including cardboard cutting, printing, creasing, folding, gluing and forming. The conventional method of folding cardboard boxes is done manually, which is inefficient.

[0003] Existing patent CN220946924U describes a high-efficiency cardboard box folding device for cardboard box processing. By moving a pull rod, a rotating rod is driven to rotate, and the rotating rod drives a moving plate to move on the inner wall of the housing. The position of the moving plate can be adjusted according to the size and specifications of the cardboard box. Then, the cardboard box is placed on the housing, and a cylinder drives a pressure plate to press down, so that the cardboard box is folded into shape by the pressure of the moving plate and the fixed plate. Therefore, manual folding is not required, which improves work efficiency.

[0004] However, when using an existing patented high-efficiency cardboard box folding device for cardboard box processing, the cardboard box will be squeezed by the pressure plate under the pressure of the pressure plate when folding the cardboard box. The upper edges of the pressure plate and the fixed plate will rub against the cardboard box, which can easily lead to damage to the cardboard box. Utility Model Content

[0005] The purpose of this utility model is to provide a folding mechanism for cardboard box processing, which solves the problem that when the aforementioned device folds the cardboard box, the cardboard box will be squeezed by the pressure plate under the pressure plate, and the upper edges of the moving plate and the fixed plate will rub against the cardboard box, which can easily lead to damage to the cardboard box.

[0006] To achieve the above objectives, this utility model provides a folding mechanism for carton processing, including an operating table, a support plate, and an upper plate. The support plate is fixedly installed on the operating table, and the upper plate is fixedly installed on the support plate. It also includes a folding device, which comprises a folding table, a flipping plate, a lower pressure roller, a connecting rod, a lower pressure assembly, and a rotating assembly. The folding table is fixedly installed on the operating table, the flipping plate is rotatably installed on the operating table via the rotating assembly, the connecting rod is installed on the upper plate via the lower pressure assembly, and the lower pressure roller is fixedly installed on the connecting rod.

[0007] The rotating assembly includes a support base and a rotating shaft. The support base is fixedly installed on the operating table. The rotating shaft is rotatably installed on the support base and fixedly connected to the flip plate.

[0008] The lower pressure roller is further provided with a first buffer sleeve and a second buffer sleeve, which are respectively fitted onto both ends of the lower pressure roller.

[0009] The pressing assembly includes a pressing plate and a guide rod, the guide rod being slidably mounted on the upper plate; the pressing plate is fixedly mounted on the guide rod, and the upper plate is also provided with a cylinder, the output end of which is fixedly connected to the pressing plate.

[0010] The flip plate is also provided with a connecting shaft and a rotating roller. A groove is provided on one side of the flip plate. The connecting shaft is fixedly installed on the flip plate and located in the groove. The rotating roller is rotatably installed on the connecting shaft.

[0011] This utility model discloses a folding mechanism for cardboard box processing. In use, cardboard is placed on the folding table, and then the cylinder is activated, causing the lower pressure plate to move the connecting rod downward. The connecting rod drives the lower pressure roller to press against both sides of the cardboard. Then, the rotating shaft is driven by a motor to rotate, and the rotation of the rotating shaft causes the two flip plates on both sides to rotate towards each other. The rotation of the flip plates causes the two sides of the cardboard to fold towards the middle. After folding, the lower pressure plate is driven upward again by the cylinder, causing the lower pressure roller to disengage from the cardboard and perform the next fold. Thus, the lower pressure roller is driven by the lower pressure assembly to press against both sides of the cardboard, and the rotating assembly drives the flip plates to rotate, folding the two sides of the cardboard, thereby reducing damage to the cardboard.

Detailed Implementation

[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0017] The embodiment of this application is as follows:

[0018] Please see Figure 1-2 , Figure 1 This is a schematic diagram of the overall structure of a folding mechanism for cardboard box processing according to this utility model. Figure 2 This is a structural schematic diagram of the folding device of this utility model.

[0019] This utility model provides a folding mechanism for carton processing: it includes an operating table 101, a support plate 102 and an upper plate 103, and a folding device. The folding device includes a folding table 104, a flipping plate 105, a lower pressure roller 106, a connecting rod 107, a pressing assembly and a rotating assembly. The rotating assembly includes a support base 108 and a rotating shaft 109. The lower pressure roller 106 is also provided with a first buffer sleeve 110 and a second buffer sleeve 111. The pressing assembly includes a lower pressure plate 112 and a guide rod 113. The flipping plate 105 is also provided with a connecting shaft 114 and a rotating roller 115. The above solution solves the problem that when the aforementioned device folds a carton, the carton is squeezed by the pressure plate under the pressure of the pressure plate, and the upper edges of the moving plate and the fixed plate rub against the carton, which can easily lead to damage to the carton.

[0020] In this embodiment, the pressing roller 106 is driven by the pressing component to press against both sides of the cardboard, and the flipping plates 105 on both sides are driven to rotate in opposite directions by the rotating component, thereby folding both sides of the cardboard and reducing damage to the cardboard.

[0021] The folding table 104 is fixedly mounted on the operating table 101. The flipping plate 105 is rotatably mounted on the operating table 101 via the rotating assembly. The connecting rod 107 is mounted on the upper plate 103 via the pressing assembly. The pressing roller 106 is fixedly mounted on the connecting rod 107. The folding table 104 has a square structure. The flipping plate 105 is arranged on both sides of the folding table 104. There are four connecting rods 107, which are arranged in pairs and symmetrically distributed along the center line of the upper plate 103. A set of pressing rollers 106 is provided between every two connecting rods 107. In use, the cardboard is placed on the folding table 104. The pressing assembly drives the pressing rollers 106 to press against both sides of the cardboard. The rotating assembly drives the flipping plates 105 on both sides to rotate towards each other, thereby folding both sides of the cardboard and reducing damage to the cardboard.

[0022] Secondly, the support base 108 is fixedly installed on the operating table 101; the rotating shaft 109 is rotatably installed on the support base 108 and fixedly connected to the flip plate 105; the support plate 102 is welded to the operating table 101; the rotating shaft 109 is driven by a motor, and the rotating shaft 109 is driven to rotate by the motor, so that the rotating shaft 109 drives the flip plate 105 to rotate, thereby realizing the rotation drive of the flip plate 105.

[0023] Furthermore, the first buffer sleeve 110 and the second buffer sleeve 111 are respectively fitted onto both ends of the lower pressure roller 106. The first buffer sleeve 110 and the second buffer sleeve 111 are made of sponge material. By setting the first buffer sleeve 110 and the second buffer sleeve 111, the pressure of the lower pressure roller 106 on the paperboard can be buffered.

[0024] Furthermore, the guide rod 113 is slidably mounted on the upper plate 103; the lower pressure plate 112 is fixedly mounted on the guide rod 113, and the upper plate 103 is also provided with a cylinder 117. The output end of the cylinder 117 is fixedly connected to the lower pressure plate 112. The guide rod 113 is arranged on both sides of the lower pressure plate 112. The lower pressure plate 112 is a flat plate structure. In use, the lower pressure plate 112, together with the guide rod 113, moves downward through the drive of the cylinder 117, causing the connecting rod 107 to move downward, thereby realizing the movement drive of the connecting rod 107.

[0025] Finally, a groove 116 is provided on one side of the flip plate 105, and the connecting shaft 114 is fixedly installed on the flip plate 105 and located in the groove 116; the rotating roller 115 is rotatably installed on the connecting shaft 114, the connecting shaft 114 is arranged on both sides of the groove 116, and the rotating roller 115 is located between the connecting shafts 114 on both sides. By setting the rotating roller 115, when the flip plate 105 comes into contact with the cardboard, the friction between the flip plate 105 and the cardboard can be reduced by the rolling of the rotating roller 115.

[0026] In this embodiment, during use, the cardboard is placed on the folding table 104, and then the cylinder 117 is activated, causing the lower pressure plate 112 to move the connecting rod 107 downward. The connecting rod 107 drives the lower pressure roller 106 to press against both sides of the cardboard. Then, the rotating shaft 109 is driven to rotate by the motor. The rotation of the rotating shaft 109 causes the flipping plates 105 on both sides to rotate towards each other. The rotation of the flipping plates 105 causes the two sides of the cardboard to fold towards the middle. After folding, the lower pressure plate 112 is driven to move upward again by the cylinder 117, causing the lower pressure roller 106 to disengage from the cardboard and perform the next fold. Thus, the lower pressure roller 106 is driven by the lower pressure assembly to press against both sides of the cardboard, and the flipping plates 105 are driven to rotate by the rotating assembly to fold the two sides of the cardboard, thereby reducing damage to the cardboard.

[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
