Description

Technical Field

[0001] This utility model relates to the technical field of packaging box creasing equipment, and more specifically, to a frustum rolling creasing mechanism and equipment. Background Technology

[0002] In the packaging industry, to ensure precise folding during the production of cardboard boxes and packaging containers, the paper needs to be pre-crimped to improve the appearance of the finished product. Furthermore, by controlling the depth and angle of the creases, the load-bearing capacity and stability of the packaging boxes can be enhanced, facilitating rapid folding and gluing on automated production lines and improving production efficiency.

[0003] The existing packaging box folding line creasing process generally adopts cam-type front creasing and cutting technology. This technology uses a cam mechanism to perform linear extrusion on the upper surface of the paper to form a V-shaped creasing groove. In other words, the cam is used to perform creasing on the printed surface of the packaging paper, and linear extrusion is performed on the surface of the paper to form a V-shaped creasing groove, thereby realizing the folding of the packaging paper.

[0004] However, due to design flaws on the front side, stacking the paper on the front side can lead to defects such as scratches and damage on the printed surface. This directly causes stress concentration and breakage of the paper fibers on the flat surface during folding, which manifests as micro-cracks or even surface peeling on the back of the fold line. This seriously affects the structural integrity and appearance quality of the finished packaging, thus having certain limitations. Utility Model Content

[0005] The purpose of this utility model is to provide a cone-shaped rolling and indentation mechanism and equipment. Through its unique synchronous linkage of the upper and lower carriages and the design of the opposing cutter heads, it brings significant benefits. Its core advantage lies in achieving efficient, accurate and stable continuous indentation operations. By adopting a synchronous movement mode in which the upper and lower carriages are rigidly connected by a drive shaft, the height consistency of the upper and lower parts when moving on the crossbeam is ensured, thereby fundamentally avoiding indentation misalignment or deviation caused by asynchronous operation, aiming to solve the problems in the prior art.

[0006] This invention is implemented as follows: a frustum rolling and creasing mechanism includes an upper carriage crossbeam and a lower carriage crossbeam. An upper running carriage is slidably mounted on the upper carriage crossbeam, and a lower running carriage is slidably mounted on the lower carriage crossbeam. The upper and lower running carriages are synchronously connected via a drive shaft. A concave rotating blade is provided on the lower part of one side of the upper running carriage, and a convex blade head mechanism is provided on the upper part of one side of the upper running carriage. The convex blade head mechanism and the concave rotating blade are arranged facing each other. A convex blade head timing belt is provided between the convex blade head mechanism and the concave rotating blade. The convex blade head timing belt is provided with a through hole, which allows the convex blade head mechanism and the concave rotating blade to abut against each other, thereby completing the creasing action on the paper passing over the convex blade head timing belt.

[0007] Furthermore, the upper running trolley is equipped with an active rotary cutter motor frame, on which an active rotary cutter motor is mounted. The output end of the active rotary cutter motor is equipped with a rotating shaft, the end of which extends to the concave rotary cutter to achieve orientation adjustment of the concave rotary cutter.

[0008] Furthermore, an upper conveyor belt is connected to the upper running trolley, and a lower conveyor belt is connected to the lower running trolley. One end of each of the upper and lower conveyor belts is connected to an active rotating roller. The opposite ends of the two active rotating rollers are each connected to a drive shaft. The ends of the two drive shafts are coaxially connected by a coupling. A trolley drive motor is installed on the frame on one side of the coupling, and the trolley drive motor is connected to the active rotating rollers in a transmission connection.

[0009] Furthermore, the convex cutter head timing belt is fixed on the lower running trolley, the trolley drive motor drives the lower running trolley to move, and the lower running trolley drives the convex cutter head timing belt to complete synchronous movement, ensuring that the through holes on the convex cutter head timing belt are all located between the convex cutter head mechanism and the concave rotating cutter.

[0010] Furthermore, a tool-matching structure is provided on the outer wall of the lower part of the convex cutter head mechanism. The tool-matching structure includes a connecting sleeve sleeved on the outside of the convex cutter head mechanism. An adjusting screw is provided on one side of the connecting sleeve, and the adjusting screw extends to the inner wall of the convex cutter head mechanism to fix the connecting sleeve.

[0011] Furthermore, a limiting part is provided on the lower outer wall of the convex cutter head mechanism, the limiting part being used to prevent the connecting sleeve from falling off the convex cutter head mechanism.

[0012] Furthermore, the convex blade mechanism includes a blade holder, a support column is provided at the top center of the blade holder, the top of the support column is conical, and an abutment part is provided at the top of the conical shape. The abutment part abuts against the concave rotating blade to realize the paper creasing operation.

[0013] Furthermore, the abutting part is a spherical fixing part, and the upper two sides of the spherical fixing part abut against the concave rotating blade to complete the paper creasing operation, and a creasing gap is formed between the upper two sides of the spherical fixing part and the abutting point of the concave rotating blade.

[0014] Furthermore, the abutting part includes a ball limiting groove provided at the top of the support column, in which a ball is placed, and the lower part of the ball is provided with a positioning post embedded in the support column. The upper two sides of the ball abut against the concave rotating blade to complete the paper creasing operation, and a creasing gap is formed between the upper two sides of the ball and the abutting point of the concave rotating blade. Furthermore, the abutting part includes a ball positioning groove disposed inside the support column, in which multiple balls are placed. The uppermost ball of the multiple balls extends to the outside, and its upper sides abut against the concave rotating blade to complete the paper creasing operation. A creasing gap is formed between the upper sides of the ball and the abutting point of the concave rotating blade. A positioning post detachably connected to the support column is disposed in the ball positioning groove. An abutting post is disposed at the top of the positioning post. The top of the abutting post is provided with a limiting groove for supporting the multiple balls, so that the uppermost ball of the multiple balls extends to the abutting part position.

[0015] Compared with the prior art, the cone rolling and indentation mechanism and equipment provided by this utility model have the following beneficial effects: 1. Through its unique synchronous linkage of upper and lower carriages and the opposing cutter head design, it brings significant benefits. Its core advantage lies in achieving efficient, precise and stable continuous creasing operations. The synchronous movement of the upper and lower carriages, rigidly connected by a drive shaft, ensures the height consistency of the two parts when moving on the crossbeam, thus fundamentally avoiding creasing misalignment or deviation caused by asynchronous operation. The opposing arrangement of the convex cutter head mechanism and the concave rotating cutter, and the coordinated work with the convex cutter head synchronous belt fixed on the lower carriage, form a precise creasing station when the through hole on the synchronous belt moves between the two cutters. This design allows the paper to continuously and automatically receive the rolling pressure generated by the combined action of the concave rotating cutter and the convex cutter head as it passes through the synchronous belt, forming a neat and uniform creasing line. The entire creasing process does not require frequent start-stop or repositioning of the equipment, greatly improving production efficiency and product consistency. 2. The ingenious design of the specific execution components further brings multiple beneficial effects, such as improved creasing quality, convenient operation and maintenance, and wide applicability. First, the contact part of the convex cutter head mechanism adopts an innovative design of a conical top combined with a spherical fixing part or a movable ball. When its upper two sides abut against the rotating concave cutter, a stable and uniform creasing gap can be formed between the two contact points. This point-contact rolling creasing method not only effectively reduces the paper tearing or excessive crushing that is easily caused by traditional fixed cutter heads, but also ensures clear creasing lines and consistent depth, significantly improving the aesthetics and bending performance of the finished product. Second, the blade alignment structure set on the convex cutter head mechanism, through the simple cooperation of the connecting sleeve and the adjusting screw, and the use of the limiting part to prevent it from falling off, makes the centering and gap adjustment of the cutter head extremely simple and quick, greatly reducing the technical dependence on operators and the debugging time for daily maintenance. Through structural optimization and detailed innovation, while ensuring high performance, it also takes into account economy and ease of use, resulting in outstanding comprehensive benefits.

The rolling and creasing mechanism performs creasing treatment on the paper to be processed. The rolling and creasing mechanism is the aforementioned frustum rolling and creasing mechanism.

[0022] Example 1 Reference Figure 1-5 As shown, the conical rolling and indentation mechanism includes an upper trolley beam 1 and a lower trolley beam 4. An upper traveling trolley 2 is slidably mounted on the upper trolley beam 1, and a lower traveling trolley 10 is slidably mounted on the lower trolley beam 4. The upper traveling trolley 2 and the lower traveling trolley 10 are synchronously connected via a drive shaft 11. A concave rotating cutter 6 is provided on the lower part of one side of the upper traveling trolley 2, and a convex cutter head mechanism 5 is provided on the upper part of one side of the upper traveling trolley 2. The convex cutter head mechanism 5 and the concave rotating cutter 6 are arranged facing each other.

The 8 is provided with a through hole, which allows the convex cutter head mechanism 5 and the concave rotating cutter 6 to abut against each other, so as to complete the creasing action on the paper passing through the synchronous belt 8 of the convex cutter head. Through its unique upper and lower carriage synchronous linkage and the oppositely arranged cutter head design, it brings significant benefits. Its core advantage is that it realizes efficient, accurate and stable continuous creasing operation. The synchronous movement mode of the upper running carriage 2 and the lower running carriage 10 rigidly connected by the drive shaft 11 ensures the height consistency of the upper and lower parts when moving on the crossbeam, thereby fundamentally avoiding creasing misalignment or deviation caused by asynchronous operation.

[0023] In this embodiment, the upper running trolley 2 is equipped with an active rotary cutter motor frame 14, an active rotary cutter motor 3 is mounted on the active rotary cutter motor frame 14, and a rotating shaft 15 is mounted on the output end of the active rotary cutter motor 3. The end of the rotating shaft 15 extends to the concave rotary cutter 6 to realize the orientation adjustment of the concave rotary cutter 6.

[0024] In this embodiment, an upper conveyor belt is connected to the upper running trolley 2, and a lower conveyor belt 7 is connected to the lower running trolley 10. One end of the upper conveyor belt and the lower conveyor belt 7 are connected to an active roller. The opposite ends of the two active rollers are connected to a drive shaft 11. The ends of the two drive shafts 11 are coaxially connected through a coupling 12. A trolley drive motor 13 is provided on the frame on one side of the coupling 12. The trolley drive motor 13 is connected to the active rollers in a transmission connection.

[0025] In this embodiment, the convex cutter head timing belt 8 is fixed on the lower running trolley 10. The trolley drive motor 13 drives the lower running trolley 10 to move, and the lower running trolley 10 drives the convex cutter head timing belt 8 to complete synchronous movement, ensuring that the through holes on the convex cutter head timing belt 8 are all located between the convex cutter head mechanism 5 and the concave rotating cutter 6.

[0026] In this embodiment, a tool-matching structure 9 is provided on the outer wall of the lower part of the convex cutter head mechanism 5. The tool-matching structure 9 includes a connecting sleeve 91 sleeved on the outside of the convex cutter head mechanism 5. An adjusting screw 92 is provided on one side of the connecting sleeve 91. The adjusting screw 92 extends to the inner wall of the convex cutter head mechanism 5 to fix the connecting sleeve 91. A limiting part 93 is provided on the lower outer wall of the convex cutter head mechanism 5. The limiting part 93 is used to prevent the connecting sleeve 91 from falling off the convex cutter head mechanism 5.

[0027] In this embodiment, the convex blade mechanism 5 includes a blade holder 51, and a support column 52 is provided at the top center of the blade holder 51. The top of the support column 52 is conical, and an abutment part 53 is provided at the top of the conical shape. The abutment part 53 abuts against the concave rotating blade 6 to realize the paper creasing operation.

[0028] In this embodiment, the contact part 53 is a spherical fixing part 54. The upper two sides of the spherical fixing part 54 abut against the concave rotating blade 6 to complete the paper creasing operation. A creasing gap is formed between the contact points of the upper two sides of the spherical fixing part 54 and the concave rotating blade 6. The convex blade head mechanism 5 is arranged facing the concave rotating blade 6 and works in coordination with the convex blade head timing belt 8 fixed on the lower running carriage 10. When the through hole on the convex blade head timing belt 8 runs between the two blades, a precise creasing station is formed. This design allows the paper to continuously and automatically receive the rolling pressure generated by the combined action of the concave rotating blade 6 and the convex blade head mechanism 5 as it passes through the convex blade head timing belt 8, forming a neat and uniform creasing line. The entire creasing process does not require frequent start-stop or repositioning of the equipment, which greatly improves production efficiency and product consistency.

[0029] In this embodiment, multiple beneficial effects are further brought about, such as improved indentation quality, convenient operation and maintenance, and wide applicability. First, the abutment part 53 of the convex cutter head mechanism 5 adopts an innovative design with a conical top combined with a spherical fixing part 54 or a movable ball 55. When its upper two sides abut against the rotating concave cutter 6, a stable and uniform indentation gap can be formed between the two contact points. This point contact rolling indentation method not only effectively reduces the paper tearing or excessive crushing phenomenon that is easy to cause with traditional fixed cutter heads, but also ensures that the indentation lines are clear and the depth is consistent, significantly improving the aesthetics and bending performance of the finished product. Second, the blade alignment structure 9 set on the convex cutter head mechanism 5, through the simple cooperation of the connecting sleeve 91 and the adjusting screw 92, and the use of the limiting part 93 to prevent it from falling off, makes the centering and gap adjustment of the cutter head extremely simple and quick, greatly reducing the technical dependence on the operator and the debugging time for daily maintenance. Through structural optimization and detailed innovation, while ensuring high performance, it also takes into account economy and ease of use, resulting in outstanding comprehensive benefits.

[0030] Example 2 Reference Figure 6 As shown, the convex blade mechanism 5 includes a blade holder 51, a support column 52 is provided at the top center of the blade holder 51, the top of the support column 52 is conical, and an abutment part 53 is provided at the top of the conical shape. The abutment part 53 abuts against the concave rotating blade 6 to realize the paper creasing operation.

[0031] In this embodiment, the abutment part 53 includes a ball limiting groove 56 provided at the top of the support column 52. A ball 55 is placed in the ball limiting groove 56. The lower part of the ball 55 is provided with a positioning post 57 embedded in the support column. The upper two sides of the ball 55 abut against the concave rotating blade 6 to complete the paper creasing operation. A creasing gap is formed between the upper two sides of the ball 55 and the abutment point of the concave rotating blade 6. The remaining technical features are the same as in Embodiment 1.

[0032] Example 3 Reference Figure 7-9 As shown, the convex blade mechanism 5 includes a blade holder 51, a support column 52 is provided at the top center of the blade holder 51, the top of the support column 52 is conical, and an abutment part 53 is provided at the top of the conical shape. The abutment part 53 abuts against the concave rotating blade 6 to realize the paper creasing operation.

[0033] In this embodiment, the abutment portion 53 includes a ball positioning groove 510 disposed inside the support column 52. Multiple ball bodies 59 are placed within the ball positioning groove 510. Each ball body 59 consists of at least four balls 55. The uppermost ball 55 of each ball body 59 extends outwards, and its upper sides abut against the concave rotating blade 6 to complete the paper creasing operation. A creasing gap is formed between the upper sides of the ball 55 and the contact points with the concave rotating blade 6. A ball positioning groove 510 is provided with... The positioning post 57 is detachably connected to the support post 52. Specifically, the positioning post 57 is threadedly fixed to the support post 52. The top end of the positioning post 57 is provided with an abutment post 58. The top end of the abutment post 58 is provided with a limiting groove for supporting the multi-ball body, so that the uppermost ball of the multi-ball body 59 extends to the abutment part 58. The use of the multi-ball body 59 causes the sliding friction resistance received by a single ball 55 to be adjusted to the rolling resistance between the balls 55. The remaining technical features are the same as in Embodiment 1.

[0034] The frustum rolling and creasing equipment includes a frame, and a rolling and creasing mechanism is installed inside the frame. The rolling and creasing mechanism performs creasing treatment on the paper to be processed. The rolling and creasing mechanism is the aforementioned frustum rolling and creasing mechanism.

[0035] This technical solution eliminates the cam rotation mechanism of the lower running trolley 10, including the drive motor, position recognition sensor, motor mounting bracket, etc., and constructs a new convex cutter head mechanism 5, tool setting structure 9, etc. The original rotary rolling mechanism is equipped with an upper running trolley 2, which mainly includes a rotary cutter head rotation drive motor and a rotary cutter head Z-axis feed voice coil motor. The improved upper running trolley 2 is retained and still has the rotary Z-axis feed function. The original rotary rolling mechanism is also equipped with a lower running trolley 10, whose main components are the same except for the lack of Z-axis feed function. The original structure uses upper and lower convex and concave wheels driven by a Z-axis infeed voice coil motor and a rotary motor to generate a certain pressure on the paper, pressing it and creating micro-deformations and grooves on the paper surface in a certain direction, forming fold marks. This is the purpose and function of the convex and concave wheel creasing knife. The improved structure retains the same purpose and function, but replaces the lower convex rotating blade and rotary head with a convex blade head mechanism 5, eliminating the rotating mechanism in the lower running carriage 10 of the original design. The convex blade head mechanism 5 is essentially a simplification of the original structure; the normal cross-section of the cam rotation process is completely consistent with the normal cross-section of the convex rotating blade. The difference is that in the original structure, both the upper and lower parts were rolling bodies, resulting in rolling friction. In the improved structure, if the convex blade head mechanism 5 is an integral mechanism, then the original two rolling bodies become one, and the lower paper and the convex blade head mechanism 5 experience sliding friction, slightly increasing the resistance. To reduce resistance, methods such as using materials with a low coefficient of friction, increasing material hardness, and changing surface roughness can be employed. If the convex cutter head mechanism 5 adopts a ball bearing pulley structure, then the rolling friction remains unchanged in the original structure before and after the improvement, as both the upper and lower parts are rolling elements.

[0036] The limited space between the convex cutter head mechanism 5 and the concave rotating cutter 6 makes the tool setting process difficult. Therefore, a connecting sleeve 91 is provided here. The connecting sleeve 91 fits perfectly onto the convex cutter head mechanism 5. When tool setting is not in use, the adjusting screw on the tool setting structure 9 is loosened, moved to the bottom of the convex cutter head mechanism 5, and the adjusting screw is tightened. When tool setting is required, the adjusting screw on the connecting sleeve 91 is loosened, the connecting sleeve 91 is moved to the top of the convex cutter head mechanism 5 about 5mm above the top of the lower conveyor belt 7, and the adjusting screw is tightened to perform the tool setting process.

[0037] Tool setting process: Loosen the locking screws on the drive shaft coupling 12 of the upper and lower trolley drive shafts 11, so that the connection of the trolley drive shafts 11 at both ends of the drive shaft coupling 12 is separated, and the trolley drive shafts 11 can move independently; loosen the adjusting screws on the connecting sleeve 91, move the connecting sleeve 91 until the uppermost part of the convex cutter head mechanism 5 exceeds the upper part of the lower conveyor belt 7 by about 5mm, and tighten the adjusting screws; move the upper running trolley 2, and at the same time, press the active rotating cutter motor frame 14 downwards along the inner circumference of the connecting sleeve 91 to make the active rotating cutter head... The outer circle gradually engages with the inner circle of the connecting sleeve 91 until the active rotary tool motor frame 14 can no longer move; the outer circle of the active rotary tool head and the inner circle of the connecting sleeve 91 are kept in engagement until the calibration is completed; the locking screws on the drive shaft coupling 12 of the upper and lower trolley drive shaft 11 are tightened, and the shaft coupling 12 causes the trolley drive shaft 11 to become the same rotating body again, at which point the tool setting process ends; the active rotary tool motor frame 14 is allowed to automatically reset; the adjusting screw on the connecting sleeve 91 is loosened, moved to the lowest part of the convex tool head mechanism 5 and locked.

[0038] The convex rotating cutter and rotary drive mechanism of the lower running carriage 10 are simplified into a fixed convex cutter head mechanism 5, and a connecting sleeve 91 design is introduced. This significantly simplifies the mechanical structure, reduces manufacturing costs, and improves the convenience and accuracy of assembly and tool setting while maintaining the original indentation function and quality. Specifically, it includes: Simplified Structure: The complex components of the original lower running carriage 10, such as the cam rotation drive motor, position sensor, and motor mounting bracket, were eliminated. A new convex cutter head mechanism 5 and cutter head mounting bracket were constructed. After the improvement, the lower mechanism is integrated with the carriage and no longer has independent rotation and Z-axis feed functions, greatly simplifying the structure.

[0039] Friction control: To address the issue of increased resistance caused by the transition from rolling friction to sliding friction in the lower part, a material optimization scheme is proposed. For example, materials with low coefficient of friction and high hardness are selected to manufacture the convex cutter head mechanism 5, or a ball bearing pulley structure is used to maintain rolling friction and ensure smooth equipment operation.

[0040] To address the problem of limited space and difficulty in tool alignment between the convex cutter head mechanism 5 and the upper concave rotating cutter 6 mechanism, a connecting sleeve 91 was specially designed. This inspection block has a ring structure, which can slide up and down along the convex cutter head mechanism 5 and be fixed by adjusting screws.

[0041] This improvement, through structural simplification and process innovation, achieves the following core advantages: Significantly reduced costs: The number of components such as the drive motor and sensors of the lower running trolley 10 has been reduced, thus lowering material costs and assembly complexity.

[0042] Improved assembly and maintenance efficiency: The design of the connecting sleeve 91 makes the tool setting process faster and more accurate, reducing the difficulty and time of debugging; Guaranteed and potentially improved performance: While maintaining or even potentially improving the indentation quality through material optimization, the overall operation may be more reliable due to the simplified structure.

[0043] In this embodiment, the entire operation process can be controlled by a computer, along with a PLC, to achieve automated operation control. In each operation stage, sensors can be set up to provide signal feedback and ensure that the steps are performed sequentially. These are all conventional knowledge in current automation control, and will not be elaborated on in this embodiment.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
