Description

Technical Field

[0001] This utility model relates to the field of carton machine technology, and more specifically to a double-line cutting blade assembly for a carton machine. Background Technology

[0002] In existing carton processing technology, according to the carton design, crease lines (or simply creases) and die-cutting are required on the cardboard. Creases are further divided into deep creases and high / low creases. Deep creases involve creating a deeper crease on top of existing straight creases to improve crease quality and stability. High / low creases refer to creases on the inner and outer flaps of the carton not being on the same straight line; that is, the crease on the inner flap is lower than the crease on the outer flap. High / low creases prevent the upper and lower flaps from overlapping and squeezing during the carton forming process, resulting in a smooth and aesthetically pleasing appearance after forming, and less springback of the outer flap when sealing. Existing carton machines generally only have one crease roller. Therefore, when performing the above processing, the machine must be stopped first, and the position of the crease roller adjusted before creases are applied. Taking the high and low pressure line process as an example, if there is only one pressure roller, the pressure roller needs to stop after pressing the low line, then move to the position of the high line and press it again. After pressing the high line, it needs to move to the position of the low line again. This repeated movement and adjustment of the position leads to low processing efficiency and wastes time. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a double-crease cutter assembly for a carton machine, which is equipped with a first crease roller and a second crease roller that can move in conjunction or independently to perform different crease processing, thereby improving processing efficiency and saving time.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a double-line cutting assembly for a carton machine, comprising a support beam, on which a movable cutting blade and a line pressing wheel are provided. The line pressing wheel includes a first line pressing wheel and a second line pressing wheel. The second line pressing wheel is provided with a linkage component, which enables the second line pressing wheel to move synchronously with the cutting blade or the second line pressing wheel to move synchronously with the first line pressing wheel.

[0005] The present invention is further configured such that: the cutting blade and the first pressing wheel are respectively disposed on both sides of the support beam, and the second pressing wheel is disposed between the cutting blade and the first pressing wheel.

[0006] The present invention is further configured such that: both the cutting blade and the first pressing wheel are provided with a power source, and the power source is used to drive the corresponding cutting blade and the first pressing wheel to move.

[0007] The present invention is further configured such that: the linkage component includes a movable part disposed on the second pressing wheel, a first connecting part disposed on the cutter part, and a second connecting part disposed on the first pressing wheel, wherein the movable part is connected to the first connecting part or the second connecting part.

[0008] The present invention is further configured such that the movable component includes a bidirectional cylinder and a piston rod.

[0009] The present invention is further configured such that the first connecting member and the second connecting member have holes adapted to the piston rod.

[0010] The present invention is further configured such that the piston rod has tapered structures at both ends.

[0011] In summary, this utility model has the following beneficial effects:

[0012] This invention comprises a first pressure roller, a second pressure roller, and a linkage component. The linkage component allows the second and first pressure rollers to move synchronously, ensuring they remain on the same straight line during movement, facilitating deep indentation processing. Simultaneously, the linkage component allows the second pressure roller to separate from the first pressure roller and move synchronously with the cutting tool. This enables the second and first pressure rollers to move independently and be staggered, allowing one to press low lines and the other high lines simultaneously, achieving rapid high and low line processing.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] This embodiment discloses a double-crease cutter assembly for a carton machine, such as... Figure 1-4 As shown, the device includes a support beam 1, on which a movable cutter 2 and a creasing wheel 3 are mounted. Specifically, the support beam 1 is equipped with several slide rails, and both the cutter 2 and the creasing wheel 3 are equipped with sliding seats, achieving sliding engagement through the slide rails and sliding seats. The creasing wheel 3 includes a first creasing wheel 31 and a second creasing wheel 32. The second creasing wheel 32 is equipped with a linkage component 4, which enables the second creasing wheel 32 to move synchronously with the cutter 2 or synchronously with the first creasing wheel 31. With the above structure, the second creasing wheel 32 has two working modes. When performing deep creasing on the cardboard, the first creasing wheel 31 and the second creasing wheel 32 only need to be on the same straight line. Thus, the linkage component 4 enables the second creasing wheel 32 and the first creasing wheel 31 to move synchronously, ensuring that the two creasing wheels always move together when adjusting their positions, making adjustment convenient. When processing high and low pressure lines on cardboard, the first pressure roller 31 and the second pressure roller 32 need to be misaligned, with one used to press the low lines and the other to press the high lines. At this time, the linkage component 4 makes the second pressure roller 32 and the cutter 2 move synchronously. The cutter 2 drives the second pressure roller 32 to move, so that the second pressure roller 32 is misaligned with the first pressure roller 31. In this way, during subsequent processing, the two pressure rollers press the high and low lines respectively. Compared with a single pressure roller, there is no need to stop the machine to adjust the position, which is faster and more efficient.

[0020] As a further preferred embodiment, the cutter 2 and the first pressing wheel 31 are respectively disposed on both sides of the support beam 1, and the second pressing wheel 32 is disposed between the cutter 2 and the first pressing wheel 31. Through the above design, the second pressing wheel 32, being in the middle position, facilitates linkage with either the cutter 2 or the first pressing wheel 31.

[0021] Furthermore, both the cutting blade 2 and the first pressure roller 31 are equipped with a power source 5, which drives the corresponding cutting blade 2 and first pressure roller 31 to move. Specifically, the power source 5 is a servo motor with gears, and a rack 6 is provided on the support beam 1. Movement is achieved through the meshing of the gears and rack 6. The servo motor can precisely control the movement distance and is easy to adjust. Correspondingly, a linear motor or ball screw can also be used to achieve movement control. The cutting blade 2 and the first pressure roller 31 move actively, while the second pressure roller 32 moves in conjunction with the cutting blade 2 according to processing requirements. This not only saves a power source for controlling the second pressure roller 32, but also allows the first pressure roller 31 and the second pressure roller 32 to be better kept in a straight line through mechanical linkage, making the structure simpler and more reliable.

[0022] Furthermore, the linkage component 4 includes a movable part 43 disposed on the second pressing roller 32, a first connecting part 41 disposed on the cutter 2, and a second connecting part 42 disposed on the first pressing roller 31. The movable part 43 is connected to either the first connecting part 41 or the second connecting part 42. Specifically, the movable part 43 includes a two-way cylinder 431 and a piston rod 432; meanwhile, the first connecting part 41 and the second connecting part 42 have holes adapted to the piston rod 432. With the above structure, referring to... Figure 3-4 ,exist Figure 3 The state 'a' above and Figure 4 In state c above, the bidirectional cylinder 431 on the second crease roller 32 drives the piston rod 432 to connect with the hole on the second connecting member 42. Thus, the first crease roller 31 and the second crease roller 32 are aligned on the same straight line and move synchronously. The two crease rollers crease the same position, achieving a deep crease on the cardboard. This is particularly effective for thick cardboard, where traditional methods struggle to create deep creases, resulting in poor subsequent folding of the carton. This application, however, pre-presses first and then performs a second deep press, ensuring stable creases and a good effect. Figure 3 The b state shown below and Figure 4 In state d below, the bidirectional cylinder driving piston rod 432 of the second crease roller 32 connects to the hole on the first connecting member 41. This causes the cutter 2 to move the second crease roller 32, misaligning it with the first crease roller 31. One roller is used for pressing low lines, and the other for pressing high lines, allowing for simultaneous processing of high and low lines on the carton board without machine downtime. This is convenient and efficient. Furthermore, in existing technologies, when processing multiple creases, especially parallel creases with small spacing, the traditional parallel arrangement of multiple crease rollers can obstruct each other, making it impossible to process creases with a spacing smaller than the thickness of the crease roller. In this application, the first and second crease rollers are misaligned and do not obstruct each other, thus allowing for the processing of even smaller crease spacing.

[0023] Furthermore, to ensure smooth operation, tapered structures are provided at both ends of the piston rod 432. The tapered structures are used to guide the piston rod 432 to be better inserted into the corresponding holes of the first or second connector.

[0024] Reference Figure 4 In this embodiment, the cutter 2, the first creasing wheel 31 and the second creasing wheel 32 are all equipped with lifting cylinders 7. The lifting cylinders 7 can control the corresponding cutter or creasing wheel to rise or fall. According to the design requirements of the carton, it can not participate in processing when rising, and can participate in processing and adjust the depth when falling.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
