Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper tape processing technology, and in particular to a paper folding mechanism for paper tape. Background Technology
[0002] Paper tape processing is a key link in packaging, printing and paper product production, and its folding efficiency and accuracy directly affect product quality and production costs.
[0003] In existing technologies, traditional folding processes mainly rely on manual assistance, resulting in low operational efficiency and poor consistency, making it difficult to meet the demands of large-scale production. With the development of automation technology, some equipment has attempted to achieve folding functionality through mechanical structures, but the following significant problems remain: First, some equipment lacks an integrated creasing function, or the creasing and folding mechanisms are independent. Due to the lack of pre-creasing guidance on the paper tape, crease misalignment or edge wrinkling easily occurs during folding, affecting product quality and requiring repeated corrections, further reducing production efficiency. Second, some existing equipment uses a single-sided folding design, requiring the left and right sides to be folded in two stages, leading to lengthy processes and complex conveying paths. Therefore, this paper presents a folding mechanism for paper tape to solve the above-mentioned technical problems. Utility Model Content
[0004] The purpose of this invention is to provide a paper folding mechanism for paper tape that addresses the shortcomings of existing technologies, thereby solving the technical problem of low folding efficiency in existing paper folding mechanisms.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A paper folding mechanism for paper tape includes a frame, a first creasing mechanism for continuously conveying and creasing the surface of the unfolded paper tape, and a right folding assembly and a left folding assembly arranged sequentially along the paper tape conveying direction. The left folding assembly and the right folding assembly are respectively used to fold the left and right length sides of the unfolded paper tape.
[0007] Furthermore, the frame is equipped with a roller conveyor assembly located at the end of the paper tape conveyor track and used for continuously conveying the folded paper tape.
[0008] Furthermore, the left and right folding components can move laterally along the width of the paper tape on the frame.
[0009] Furthermore, at least two first threaded rods and at least two second threaded rods are rotatably mounted on the frame, the length directions of the first and second threaded rods being parallel to the width direction of the paper tape during the conveying process; the right folding assembly is threadedly connected to the first threaded rod, and the left folding assembly is threadedly connected to the second threaded rod.
[0010] Furthermore, the right folding assembly includes a support frame threadedly connected to the first threaded rod. The support frame is equipped with a first tray and a second tray arranged sequentially along the paper tape conveying direction for supporting the paper tape during the folding process. A guide roller is rotatably provided between the first tray and the second tray. The guide roller is arranged laterally and perpendicular to the paper tape conveying direction. A folding guide oblique block is provided on the side of the right end of the guide roller for guiding the right long side of the paper tape to bend.
[0011] Furthermore, the first pallet is arranged at an angle from bottom to top, and the second pallet is arranged at an angle from top to bottom. The end of the first pallet at the higher position is connected to the beginning of the second pallet at the higher position, and the steering roller is placed between the two ends where the first and second pallets are connected.
[0012] Furthermore, the right side of the second tray is provided with a limiting plate for limiting the paper tape whose right length side is folded.
[0013] Furthermore, the limiting plate is provided with several support rods arranged in an array along the conveying direction of the paper tape, and each support rod is provided with a paper pressing limiting piece for pressing the edge of the paper tape flat after folding.
[0014] Furthermore, the roller conveying assembly includes a support frame mounted on a frame, a first conveying roller rotatably mounted on the support frame with its axis arranged laterally and perpendicular to the conveying direction of the paper strip, and a fixing frame rotatably mounted on the fixing frame for pressing the paper strip onto the first conveying roller.
[0015] Furthermore, the support frame is rotatably provided with a second conveying roller and a third threaded rod whose axis is parallel to the axis of the first conveying roller. Several control components are provided on the third threaded rod, and each control component is equipped with a second pressure roller for flattening the folded paper strip. The control components are used to control the second pressure roller to move closer to or away from the second conveying roller.
[0016] The beneficial effects of this utility model are as follows: Before operating this origami mechanism, the paper tape is laid out. The operator first folds the right length side of the end section of the paper tape and lets the folded section pass through the right folding component. Under the action of the right folding component, the right length side of the paper tape continuously transitions from the unfolded state to the folded state during the continuous conveying process. Then, the operator folds the left length side of the end section of the paper tape and lets it pass through the left folding component. Under the action of the left folding component, the left length side of the paper tape continuously transitions from the unfolded state to the folded state during the continuous conveying process.
[0017] When the equipment is running, the first creasing mechanism is activated, driving the unfolded paper tape to be continuously conveyed to the right folding assembly. Since the right length side of the paper tape reaching the right folding assembly is folded, while the paper tape at the first creasing mechanism is unfolded, the paper tape can gradually transition from the unfolded state to the right length side being folded during continuous conveying, and the folding process is natural and smooth. After the paper tape with the right length side folded is conveyed to the left folding assembly, since the left length side of the paper tape reaching the left folding assembly is folded, while the right length side of the paper tape at the right folding assembly is folded, the paper tape with the right length side folded can gradually transition to the paper tape with both left and right length sides folded during continuous conveying, realizing automatic and continuous paper folding processing and improving folding efficiency.
[0018] In addition, the first creasing mechanism can creasing the surface of the paper strip during the continuous feeding of the unfolded paper strip to create dotted or straight marks, which can prevent the paper strip from being folded crooked in the subsequent folding process and improve the efficiency and accuracy of folding.

[0029] The following is a detailed description of a paper folding mechanism for paper tape according to the present invention, with reference to the accompanying drawings.
[0030] like Figure 1-2 As shown, an embodiment of the folding mechanism for paper tape of this utility model includes a frame 301, a first creasing mechanism 4 for continuously conveying the unfolded paper tape 200 and creasing its surface, and a right folding component 303 and a left folding component 305 arranged sequentially along the conveying direction of the paper tape 200. The left folding component 305 and the right folding component 303 are respectively used to fold the left and right length sides of the unfolded paper tape 200. The frame 301 is equipped with a roller conveying component 306 placed at the end of the conveying trajectory of the paper tape 200 and used to continuously convey the folded paper tape 200.
[0031] The roller conveyor assembly 306 connects to the next mechanism. Before operating this folding mechanism, the paper tape 200 is laid out. The operator first folds the right length side of the end section of the paper tape 200, allowing the folded section to pass through the right folding assembly 303. Under the action of the right folding assembly 303, the right length side of the paper tape 200 continuously transitions from an unfolded state to a folded state during continuous conveying. Subsequently, the operator folds the left length side of the end section of the paper tape 200, allowing it to pass through the left folding assembly 305. Under the action of the left folding assembly 305, the left length side of the paper tape 200 continuously transitions from an unfolded state to a folded state during continuous conveying (e.g., ...). Figure 7 As shown, the paper tape 200 passes through the roller conveyor assembly 306 after being folded twice (left and right), and the roller conveyor assembly 306 clamps and conveys the folded paper tape 200.
[0032] When the equipment is running, the first creasing mechanism 4 and the roller conveying assembly 306 start simultaneously. The first creasing mechanism 4 drives the unfolded paper tape 200 to be continuously conveyed to the right folding assembly 303. Since the right length side of the paper tape 200 reaching the right folding assembly 303 is folded, while the paper tape 200 at the first creasing mechanism 4 is unfolded, the paper tape 200 can gradually transition from an unfolded state to a folded right length side during continuous conveying. The folding process is natural and smooth. Similarly, the right length side of the paper tape 200 is folded and then conveyed to the left folding assembly 305. Since the left length side of the paper tape 200 reaching the left folding assembly 305 is folded, while the right length side of the paper tape 200 at the right folding assembly 303 is folded, the paper tape 200 with a folded right length side can gradually transition to a paper tape 200 with both length sides folded during continuous conveying (e.g., ...). Figure 7 As shown), the folded paper tape 200 is finally clamped and conveyed by the roller conveyor assembly 306 to the next mechanism for processing.
[0033] In addition, during the continuous feeding of the unfolded paper strip 200 by the first creasing mechanism 4, the surface of the paper strip 200 will be creasing to create dotted or straight lines. This will improve the folding efficiency and prevent the paper strip 200 from being folded crookedly during the subsequent folding process by the left folding assembly 305 and the right folding assembly 303.
[0034] In this embodiment, the left folding assembly 305 and the right folding assembly 303 can move laterally along the width direction of the paper tape 200 on the frame 301. Specifically, at least two first threaded rods 302 and at least two second threaded rods 304 are rotatably mounted on the frame 301. The length directions of the first threaded rods 302 and the length directions of the second threaded rods 304 are both parallel to the width direction of the paper tape 200 during the conveying process. The right folding assembly 303 is threadedly connected to the first threaded rods 302, and the left folding assembly 305 is threadedly connected to the second threaded rods 304. When multiple first threaded rods 302 are driven to rotate synchronously, the right folding assembly 303 can be controlled to move laterally along the width direction of the paper tape 200 on the frame 301. Similarly, when multiple second threaded rods 304 are driven to rotate synchronously, the left folding assembly 305 can be controlled to move laterally along the width direction of the paper tape 200 on the frame 301. By controlling the positions of the left folding assembly 305 and the right folding assembly 303, the folding positions of the left and right length sides of the paper tape 200 can be adjusted, thereby folding the paper tape 200 into different states (such as...). Figure 8 (As shown).
[0035] Additionally, a second creasing mechanism 41, which functions identically to the first creasing mechanism 4, is provided between the right folding assembly 303 and the left folding assembly 305. The second creasing mechanism 41 and the first creasing mechanism 4 are controlled separately. When it is necessary to fold the right length side of the paper tape 200 separately, the second threaded rod 304 is driven to rotate, thereby controlling the left folding assembly 305 to deviate from the conveying trajectory of the paper tape 200. The first creasing mechanism 4 then presses only one creasing mark on the surface of the paper tape 200, thus folding only the right length side of the paper tape 200. Similarly, the first threaded rod 302 is driven to rotate, thereby controlling the right folding assembly 303 to deviate from the conveying trajectory of the paper tape 200. The second creasing mechanism 41 then presses only one creasing mark on the surface of the paper tape 200, thus folding only the left length side of the paper tape 200.
[0036] like Figure 3-5 As shown, the right folding assembly 303 includes a support frame 3031 threadedly connected to the first threaded rod 302. The support frame 3031 is equipped with a first tray 3032 and a second tray 3033 arranged sequentially along the conveying direction of the paper tape 200 and used to support the paper tape 200 during the folding process. The first tray 3032 is arranged inclined from bottom to top, and the second tray 3033 is arranged inclined from top to bottom. The end of the first tray 3032 at the higher position is connected to the beginning of the second tray 3033 at the higher position. A turning roller 3034 for turning the paper tape 200 during the folding process is rotatably provided between the two connected ends. The turning roller 3034 is arranged laterally and perpendicular to the conveying direction of the paper tape 200. A folding guide inclined block 3035 for guiding the right long side of the paper tape 200 to bend is provided on the side of the right end of the turning roller 3034. During the continuous conveying of the paper tape 200, the paper tape 200 first passes through the first pallet 3032 to be conveyed from bottom to top. Under the turning action of the turning roller 3034, the paper tape 200 then passes through the second pallet 3033 to be conveyed from top to bottom. During the process of turning from the first pallet 3032 to the second pallet 3033, under the guidance of the folding guide block 3035, the right length side of the guide tape 200 is bent and folded, gradually transitioning from an unfolded state to a folded state on the right length side, thereby realizing the continuous folding process.
[0037] Additionally, a limiting plate 3036 is provided on the right side of the second pallet 3033 to limit the right length edge of the paper tape 200 in a folded state. After the right length edge of the paper tape 200 is folded, it is limited by the limiting plate 3036 during conveying to prevent deviation. Several support rods 3037 are arranged in an array along the conveying direction of the paper tape 200 on the limiting plate 3036. Each support rod 3037 is equipped with a paper-pressing limiting piece 3038 to flatten the folded edge of the paper tape 200. During the folding and conveying process of the paper tape 200, the folded edge passes between the paper-pressing limiting piece 3038 and the surface of the second pallet 3033. Under the pressure applied by the paper-pressing limiting piece 3038, the folded edge of the paper tape 200 is flattened, improving the folding effect. The paper-pressing limiting piece 3038 also serves to limit and guide the paper tape 200, improving conveying efficiency.
[0038] The right folding assembly 303 and the left folding assembly 305 are symmetrically arranged one in front of the other based on the conveying trajectory of the paper tape 200. The folding guide slant block 3035 on the right folding assembly 303 is located on the side of the right end of the guide roller 3034, while the folding guide slant block 3035 on the left folding assembly 305 is located on the side of the left end of the guide roller 3034. Therefore, the left length side of the guide tape 200 is bent and folded, and the folding state gradually transitions from the right length side to both the left and right length sides being folded.
[0039] like Figure 6 As shown, the roller conveying assembly 306 includes a support frame 3061 mounted on the frame 301. The support frame 3061 is rotatably provided with a first conveying roller 3062 arranged laterally on the axis and perpendicular to the conveying direction of the paper tape 200. A fixing frame 3063 is also provided. A first pressure roller 3064 for pressing the paper tape 200 onto the first conveying roller 3062 is rotatably provided on the fixing frame 3063. The fixing frame 3063 can rotate on the support frame 3061, thereby bringing the first pressure roller 3064 closer to or away from the first conveying roller 3062. The first conveying roller 3062 receives the folded paper strip 200. After the paper strip 200 passes between the first conveying roller 3062 and the first pressure roller 3064, the fixing frame 3063 is controlled to rotate, so as to bring the first pressure roller 3064 closer to the first conveying roller 3062. The first pressure roller 3064 presses the paper strip 200 onto the first conveying roller 3062. Then, the first conveying roller 3062 is driven to rotate. Under the action of friction between the surface of the first conveying roller 3062 and the surface of the paper strip 200, a pulling force is generated on the paper strip 200, thereby realizing the continuous conveying of the paper strip 200.
[0040] In addition, the support frame 3061 is rotatably equipped with a second conveying roller 3066 and a third threaded rod 3067, the axis of which is parallel to the axis of the first conveying roller 3062. The third threaded rod 3067 is equipped with several control components 3068, each of which is fitted with a second pressure roller 3069 for flattening the folded paper tape 200. The control components 3068 control the second pressure roller 3069 to move closer to or away from the second conveying roller 3066. After the folded paper tape 200 is conveyed by the first conveying roller 3062, it passes between the second conveying roller 3066 and the second pressure roller 3069. Then, the control components 3068 are activated to control the second pressure roller 3069 to move closer to the second conveying roller 3066, pressing the paper tape 200 firmly onto the second conveying roller 3066, thereby achieving the flattening of the paper tape 200. The first pressure roller 3064 and the second pressure roller 3069 are made movable to facilitate the pre-laying of the paper tape 200 by the operator. Secondly, depending on the different dimensions of the folded paper tape 200, the third threaded rod 3067 can be driven to rotate to control the position of each control component 3068, thereby adjusting the flattening position so that the second pressure roller 3069, which is located on the far side, is aligned with the edge of the folded paper tape 200.
[0041] The support frame 3061 is equipped with a first guide roller 3065 positioned between the first conveying roller 3062 and the second conveying roller 3066, and a second guide roller 30610 for guiding the folded paper tape 200 to the next mechanism. The folded paper tape 200 is sequentially wound around the first conveying roller 3062, the first guide roller 3065, the second conveying roller 3066, and the second guide roller 30610 along the conveying direction, and is guided during the conveying process so that the paper tape 200 is conveyed in the specified direction.
[0042] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.
[0043] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
