Description

Technical Field

[0001] The utility model relates to the technical field of carton processing, in particular to a high-efficiency carton folding device for carton processing. Background Art

[0002] After the cartons are manufactured to the required size, they need to be folded, not only to allow the cartons to be opened directly when used, but also to facilitate transportation of the cartons.

[0003] According to a disclosed high-efficiency carton folding device for carton processing (publication number: CN220535048U), in the above application, the distance between the two support platforms can be adjusted through the first connecting rod. At the same time, according to the size of the distance, the support plates of different sizes can be disassembled and replaced through the second connecting rod. A gap of the thickness of the carton is left between the support plate and the support platforms on both sides, and the folding plate of the same size as the support can be replaced through the third connecting rod. Different sizes of cartons can be folded, and the application is more flexible.

[0004] However, in actual use of the above-mentioned equipment, when the cardboard is folded, the downward movement between the folding plate and the supporting plate causes the part of the carton between the supporting plate and the supporting platform to bend. However, when the carton board is deformed by the downward pressure, it will also produce a large friction between it and the supporting platform, which can easily cause damage to the surface of the carton board and affect the processing quality of the carton board. In view of this, we propose an efficient carton folding device for carton processing. Summary of the invention

[0005] The purpose of the utility model is to provide a high-efficiency carton folding device for carton processing to solve the problems raised in the above-mentioned background technology.

[0010] Preferably, there are three groups of elastic telescopic rods, and the three groups of elastic telescopic rods are distributed in a triangle on the upper surface of the support platform to ensure the stability of the rise and fall of the support plate.

[0011] Preferably, a notch groove having a width matching the width of the flip plate is provided on the inner wall of the support platform on one side close to the support plate, so that the flip plate can rotate at a large angle in the notch groove without getting stuck.

[0012] Preferably, a T-shaped groove matching the size of the T-shaped slider is provided on the bottom inner wall of the flip plate, so that when the flip plate rotates with the connection between the flip plate and the support platform as the rotation center, there will be no motion interference with the rotation of the flip plate.

[0016] 1. The high-efficiency carton folding device for carton processing is provided with a flipping mechanism. After the pressing plate contacts the carton board and continuously drives the supporting plate to move downward, the transmission limit of the round rod and the straight groove is cooperated to make the transmission rod deflect, thereby pushing the auxiliary rod and the flipping plate to deflect toward one side of the supporting plate on the supporting platform, so as to generate neat indentations at the left and right edges of the carton board and the pressing plate. In addition, due to the upward deflection of the flipping plates on the left and right sides of the supporting plate, the carton board will not be worn with the supporting platform when the folding marks are pressed down, thereby ensuring the processing quality of the carton board and avoiding damaged and defective products.

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a high-efficiency carton folding device for carton processing, comprising a bottom plate 1, the upper surface of the bottom plate 1 is fixedly connected to a top plate 2 through a square column, a hydraulic cylinder 3 is fixedly installed on the upper surface of the top plate 2, the output end of the hydraulic cylinder 3 is fixedly connected to a transmission column 4, the bottom end of the transmission column 4 is fixedly connected to a pressing plate 5, a support platform 7 is fixedly installed on the upper surface of the bottom plate 1, an elastic telescopic rod 8 is fixedly installed on the top of the support platform 7, the top of the elastic telescopic rod 8 is fixedly connected to a support plate 9, a support platform 10 is fixedly installed on the upper surface of the bottom plate 1, a flip mechanism is arranged inside the support platform 10, and the flip mechanism comprises a flip plate 11, a vertical rod 12, a transmission rod 13, a straight groove 14, a round rod 15, an auxiliary rod 16 and a T-shaped slider 17.

[0024] In one embodiment of the utility model, a flip plate 11 is rotatably installed on the inner wall of the support platform 10, and a vertical pole 12 is fixedly connected to the lower surface of the supported plate 9. A transmission rod 13 is hinged at the bottom end of the vertical pole 12, and a straight groove 14 is opened on the inner wall of the transmission rod 13. A round rod 15 is fixedly installed on the bottom outer wall of the support platform 10, and the round rod 15 is arranged inside the straight groove 14. An auxiliary rod 16 is rotatably connected to one end of the transmission rod 13 away from the vertical pole 12, and a T-shaped slider 17 is fixedly connected to the top of the auxiliary rod 16. The T-shaped slider 17 is rotatably connected to the lower surface of the flip plate 11.

[0025] Furthermore, there are two groups of support platforms 10, and the two groups of support platforms 10 are mirror-imaged on the left and right sides of the support plate 9. At the same time, the upper surface of the support plate 9 is flush with the upper surface of the support platform 10 in the initial state, so that the carton board will not get stuck on the device during transportation for folding operations, thereby ensuring the stability of loading. In addition, there are three groups of elastic telescopic rods 8, and the three groups of elastic telescopic rods 8 are distributed in a triangular shape on the upper surface of the support platform 7 to ensure the stability of the rise and fall of the support plate 9, thereby ensuring that the folds of the carton board will not be skewed or broken when folding. Specifically, a notch groove with a width matching the width of the flip plate 11 is provided on the inner wall of the support platform 10 on the side close to the support plate 9, so that the flip plate 11 can be rotated at a large angle in the notch groove without getting stuck, ensuring that the flip plate 11 can provide a stable upward lifting effect when the carton board is folded, which is helpful for the folding of the carton board.

[0026] In addition, when the support plate 9 is kept flush with the upper surface of the support platform 10, the transmission rod 13 is in a horizontal state, and a T-shaped groove matching the size of the T-shaped slider 17 is provided on the bottom inner wall of the flip plate 11, so that when the flip plate 11 rotates with the connection between it and the support platform 10 as the rotation center, the T-shaped slider 17 will slide along the T-shaped groove without causing motion interference with the rotation of the flip plate 11. At the same time, when the support plate 9 is subjected to the downward pressure of the pressure plate 5, the vertical rod 12 moves downward in the vertical direction, thereby driving the right end of the transmission rod 13 downward. At this time, due to the straight groove The cooperation between 14 and the round rod 15 makes the transmission rod 13 use the round rod 15 as a fulcrum to exert a lever effect and generate an upward pushing force on the auxiliary rod 16, and then cooperates with the T-shaped slider 17 to make the flip plate 11 close to the support plate 9 to deflect downward. At this time, due to the pressure of the pressing plate 5 on the carton board, neat indentations are generated on the left and right edges of the carton board and the pressing plate 5, and due to the upward deflection of the flip plates 11 on the left and right sides of the support plate 9, the carton board will not be worn with the support platform 10 when the folding marks are pressed down, thereby ensuring the processing quality of the carton board and avoiding damaged and defective products.

[0027] In the embodiment of the utility model, a rotating groove is opened on the upper surface of the flip plate 11, and an auxiliary roller 18 is rotatably installed on the inner surface of the rotating groove, and a spiral belt 19 is arranged on the arc-shaped outer surface of the auxiliary roller 18. Specifically, there are several groups of auxiliary rollers 18, and several groups of auxiliary rollers 18 are uniformly distributed in the rotating groove in a linear array. At the same time, the diameter of the auxiliary roller 18 is large at both ends and narrow in the middle, so that the diameter of the auxiliary roller 18 becomes larger from the middle to both ends, and the spiral belt 19 is completely attached to the outer surface of the auxiliary roller 18. When the carton board is relatively displaced with the surface of the auxiliary roller 18 as the flip plate 11 rotates, the auxiliary roller 18 will rotate with the movement of the carton board. At this time, due to the design of the auxiliary roller 18 being large at both ends and narrow in the middle, the carton board can ensure the centering state on the flip plate 11, and will not be skewed during the folding process, thereby affecting the processing quality of the carton board.

[0028] In the utility model, when in use, the carton board to be processed is conveyed to the support platform 10 through external feeding equipment or manual conveying, and the carton board is set in the center. At this time, the hydraulic cylinder 3 is started so that the transmission column 4 drives the pressure plate 5 to move downward, so that the lower surface of the pressure plate 5 contacts the carton board and then continues to press down to generate downward pressure on the support plate 9. At this time, since the vertical rod 12 continues to move downward with the support plate 9, the right end of the transmission rod 13 is driven downward. At this time, due to the cooperation between the straight groove 14 and the round rod 15, the transmission rod 13 will use the round rod 15 as a fulcrum to show a lever effect and generate an upward driving force on the auxiliary rod 16, and then cooperate with the T-shaped slider 17, so that the flip plate 11 will deflect downward on the side close to the support plate 9. At this time, due to the pressure of the pressure plate 5 on the carton board, neat indentations are generated on the left and right edges of the carton board and the pressure plate 5.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
