Description

An automated tape rewinding machine Technical Field

[0001] This utility model relates to the field of adhesive tape preparation technology, and in particular to an automated adhesive tape rewinding machine. Background Technology

[0002] In existing technologies, the production process of adhesive tape generally includes processes such as feeding the paper tube, rolling the paper, attaching the top label, and unloading the material. Each process often requires a separate piece of equipment. Because the equipment exists independently, it can generally only be arranged horizontally in the production site, resulting in large-scale equipment. When the horizontal space is limited, the currently independent process equipment cannot be deployed, thus making the large-scale layout of existing equipment unable to meet the usage requirements. Summary of the Invention

[0003] Based on this, the purpose of this utility model is to provide an automated tape rewinding machine to solve the technical problem that existing multi-process equipment is scattered and independently set up, with low integration, which makes it unable to meet the requirements of small-site use.

[0004] This utility model provides an automated tape rewinding machine, including a tape winding mechanism. The automated tape rewinding machine includes: a frame, a rewinding mechanism disposed on the frame, and a tape breaking mechanism movably connected to the rewinding mechanism. The rewinding mechanism receives the tape from the tape winding mechanism to achieve tape rewinding.

[0005] The glue-cutting mechanism is located above the rewinding mechanism, and the glue-cutting mechanism includes a cutting blade;

[0006] The rewinding mechanism includes four rewinding drums and four support rods. The rewinding drums are used to fit the tape bottom drum so that when the rewinding drum rotates, it drives the tape to be rewound onto the tape bottom drum. The four rewinding drums are arranged in a square interval.

[0007] The rewinding mechanism also includes a central rotating shaft, which is located at the center of the layout of the four rewinding drums. The central rotating shaft drives the four rewinding drums to rotate along the central rotating shaft so that the position of the four rewinding drums changes periodically relative to the glue-breaking mechanism.

[0008] The four support rods are staggered with the four rewinding drums, and the axis of the support rods is lower than the axis of the rewinding drums. When the tape cutting mechanism is pressed down, it contacts the rewinding drums and support rods, thereby pressing the tape rewound to the bottom drum of the tape, so that the cutting blade can cut the tape and separate the tape after rewinding to obtain tape rolls.

[0009] The aforementioned automated tape rewinding machine integrates the equipment required for feeding, paper rolling, finished product cutting, and unloading processes into four rewinding drums within a single rewinding mechanism. This avoids separate setups, reduces site requirements, and offers high flexibility. Specifically, the rewinding mechanism includes four rewinding drums and four support rods. The rewinding drums are used to mount the tape bottom drum so that when the rewinding drums rotate, they drive the tape to rewind onto the tape bottom drum. The four rewinding drums are arranged in a square interval. The rewinding mechanism also includes a central rotating shaft, located at the center of the four rewinding drums. The central rotating shaft drives the four rewinding drums to rotate along the central rotating shaft, causing the positions of the four rewinding drums to change periodically relative to the tape-cutting mechanism. The four support rods are staggered with the four rewinding drums, and the axis of the support rods is lower than the axis of the rewinding drums. When the tape-cutting mechanism presses down, it contacts the rewinding drums and support rods, thereby pressing the tape rewindn onto the tape bottom drum so that the cutting blade can cut the tape, achieving tape separation after rewinding to obtain tape rolls.

[0010] In addition, the automated tape rewinding machine described above according to this utility model may also have the following additional technical features:

[0011] Furthermore, the four rewinding tubes, from left to right and from top to bottom, include a first rewinding tube, a second rewinding tube, a third rewinding tube, and a fourth rewinding tube;

[0012] The automated tape rewinding machine also includes a feeding mechanism, which includes a feeding guide rail and a feeding push rod. The feeding guide rail is connected to the third rewinding drum so that the tape bottom tube on the feeding guide rail is sleeved onto the third rewinding drum by the feeding push rod. The second rewinding drum is connected to the tape winding mechanism to receive the rewinding tape and realize tape rewinding. The first rewinding drum receives the tape roll obtained after being cut by the cutting blade.

[0013] Furthermore, the automated tape rewinding machine also includes an unloading mechanism, which includes a support base and a material ejection assembly movably connected to the support base; the unloading mechanism also includes a first unloading cylinder and a second unloading cylinder, the first unloading cylinder driving the material ejection assembly to reciprocate along the support base;

[0014] The unloading assembly includes a movable seat, a gripper mounted on the movable seat, and a movable bracket connecting the gripper and the movable seat. The gripper is movably connected to a fourth rewinding drum to push the cut tape roll onto the unloading guide rail. The movable seat is slidably connected to the support base. The unloading second cylinder drives the movable bracket to slide and connect with the movable seat so that the gripper fits against the fourth rewinding drum, thereby achieving unloading.

[0015] Furthermore, the automated tape rewinding machine also includes a paper pasting mechanism, which includes a sticker guide rail, a sticker carriage disposed on the sticker guide rail, and a paper receiving rod. The sticker carriage includes a sticker traction component.

[0016] The oral paper pasting mechanism further includes a first sticker cylinder and a second sticker cylinder. The first sticker cylinder is connected to the sticker carriage to drive the sticker carriage to reciprocate along the sticker guide rail. The second sticker cylinder is connected to the sticker traction member to attract and disconnect the sticker. The paper receiving rod receives the oral paper attracted by the sticker traction member to paste the oral paper onto the tape.

[0017] Furthermore, the glue-cutting mechanism includes a crossbeam and a movable component movably connected to the crossbeam, the cutting blade is connected to the movable component, and the crossbeam is movably connected to the rewinding mechanism to contact the rewinding drum and the support rod;

[0018] The tape-cutting mechanism also includes a rotating component and a tape-cutting cylinder. The rotating component drives the crossbeam to move up and down periodically to connect the rewinding drum and the support rod. The tape-cutting cylinder drives the movable component to reciprocate along the crossbeam so that the cutting blade cuts the tape. Attached Figure Description

[0028] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0029] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0030] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] To address the technical problem of existing technologies where multiple process devices exist independently, are scattered and have low integration, thus failing to meet the requirements of small spaces, this application provides an automated tape rewinding machine. By integrating the equipment needed for feeding, paper winding, finished product cutting, and unloading processes into four rewinding drums within a single rewinding mechanism, it avoids separate setups, reduces space requirements, and offers high flexibility. Specifically, the rewinding mechanism includes four rewinding drums and four support rods. The rewinding drums are used to mount the tape bottom drum so that the tape is rewound when the rewinding drum rotates. Four rewinding drums are arranged in a square interval on the bottom drum of the tape. The rewinding mechanism also includes a central rotating shaft, which is located at the center of the layout of the four rewinding drums. The central rotating shaft drives the four rewinding drums to rotate along the central rotating shaft so that the position of the four rewinding drums changes periodically relative to the tape-cutting mechanism. Four support rods are staggered with the four rewinding drums and the axis of the support rods is lower than the axis of the rewinding drums. When the tape-cutting mechanism is pressed down, it contacts the rewinding drums and support rods, thereby pressing the tape rewound to the bottom drum of the tape so that the cutting blade can cut the tape and separate the tape after rewinding to obtain tape rolls.

[0033] To facilitate understanding of this utility model, several embodiments are provided below. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0034] Example 1

[0035] Please refer to Figures 1-6, which show the automated tape rewinding machine in the first embodiment of this utility model. The automated tape rewinding machine includes: a frame 100, a rewinding mechanism 200 disposed on the frame 100, and a tape cutting mechanism movably connected to the rewinding mechanism 200. The rewinding mechanism 200 receives the rewinding tape from the rewinding mechanism to realize tape rewinding; the tape cutting mechanism is disposed above the rewinding mechanism 200 and includes a cutting blade.

[0036] The rewinding mechanism 200 includes a rewinding drum assembly and a support rod assembly. The rewinding drum assembly includes four rewinding drums, and the support rod assembly includes four support rods. Specifically, the four rewinding drums, from left to right and from top to bottom, are a first rewinding drum 210, a second rewinding drum 220, a third rewinding drum 230, and a fourth rewinding drum 240. The rewinding drums are used to mount the tape base tube (i.e., the paper tube) so that when the rewinding drum rotates, it drives the tape to rewind onto the tape base tube. The tape base tube is cylindrical and is used to shape the tape during rewinding, ensuring that the rewound tape is ultimately cylindrical. The tape rewound onto the tape base tube can be cut into multiple independent segments to meet the size requirements of commercially available tapes. Furthermore, the four rewinding drums are arranged in a square-spaced configuration, meaning that the cross-section of the four rewinding drums in space is similar to a square.

[0037] To provide rotational power to the rewinding mechanism 200 for dynamically adjusting the relative positions of the four rewinding drums, the rewinding mechanism 200 further includes a turntable, a central rotating shaft 250 mounted on the turntable, and a power device connected to the central rotating shaft 250. This power device includes a motor. The four rewinding drums and four support rods are all mounted on the same side of the turntable, which is rotatably connected to the frame 100 via the motor. Furthermore, to ensure balance during turntable rotation, in this embodiment, the central rotating shaft 250 is positioned at the center of the four rewinding drums. The central rotating shaft 250 drives the four rewinding drums to rotate along the central rotating shaft 250, causing the positions of the four rewinding drums relative to the adhesive-breaking mechanism to change periodically.

[0038] The rewinding mechanism 200 also includes a limiting component 500, which includes two sets of limiting members 510 and a limiting cylinder 520 connected to the limiting members 510. The limiting cylinder 520 drives the limiting members 510 to reciprocate and extend. The turntable and the limiting members 510 are respectively located at both ends of the rewinding drum. Furthermore, the two sets of limiting members 510 are respectively located at the ends of the first rewinding drum 210 and the second rewinding drum 220 away from the turntable. When the second rewinding drum 220 needs to rewind the tape or cut the tape on the first rewinding drum 210, the limiting cylinder 520 extends to drive the limiting members 510 to abut against the second rewinding drum 220 or the first rewinding drum 210 to achieve limiting. After the operation is completed, the limiting cylinder 520 retracts to drive the limiting members 510 to retract, so as to avoid restricting the turntable from driving the rewinding drum to rotate.

[0039] It should be further explained that in this scheme, the central rotating shaft 250 rotatably connects the two ends of the frame 100 to fix the rewinding mechanism 200 on the frame 100, and the support rod is fixed in the same body as the central rotating shaft 250. However, the rewinding drum is only fixed to the turntable at one end, and suspended and not connected to the frame 100 at the other end, which facilitates the limiting of the rewinding drum, the feeding of the rewinding drum, and the unloading of the rewinding drum.

[0040] As a specific example, the tape-cutting mechanism includes a crossbeam and a movable component movably connected to the crossbeam. The cutting blade is connected to the movable component. The crossbeam is movably connected to the rewinding mechanism 200 to contact the rewinding drum and the support rods. Furthermore, in order to enable the crossbeam to better contact the rewinding drum and the support rods to compress the tape for easy cutting by the cutting blade, in this embodiment, the four support rods are staggered with the four rewinding drums, and the axis of the support rods is lower than the axis of the rewinding drum to form a limiting area. When the tape-cutting mechanism presses down, the crossbeam enters the limiting area and contacts the rewinding drum and the support rods, thereby pressing the tape rewound to the bottom drum of the tape so that the cutting blade can cut the tape and achieve separation of the tape after rewinding to obtain a tape roll.

[0041] Furthermore, to facilitate the cutting operation of the cutting blade, in this embodiment, the adhesive cutting mechanism also includes a rotating component and an adhesive cutting cylinder. The rotating component drives the crossbeam to move up and down periodically to movably connect the rewinding drum and the support rod; the adhesive cutting cylinder drives the movable component to reciprocate along the crossbeam so that the cutting blade cuts the tape.

[0042] To achieve efficient feeding and improve rewinding efficiency, as a specific example, the automated tape rewinding machine also includes a feeding mechanism. The feeding mechanism includes a feeding guide rail and a feeding pusher. The feeding guide rail connects to the third rewinding drum 230 so that the tape bottom roll on the feeding guide rail is sleeved onto the third rewinding drum 230 via the feeding pusher. After the third rewinding drum 230 finishes rewinding the tape, a power motor drives a turntable to rotate, causing the third rewinding drum 230 to move to the position of the fourth rewinding drum 240, thus switching to the fourth rewinding drum 240. Furthermore, the second rewinding drum 220 connects to the tape winding mechanism to receive the rewound tape and achieve tape rewinding. The first rewinding drum 210 receives the tape roll obtained after being cut by the cutting blade.

[0043] It should be further explained that the first rewinding drum 210, the second rewinding drum 220, the third rewinding drum 230, and the fourth rewinding drum 240 in this embodiment are named according to the tape rewinding process and their corresponding positions, under a certain working state. Since the four rewinding drums and the four support rods rotate periodically, their working states change. Therefore, the first rewinding drum 210, the second rewinding drum 220, the third rewinding drum 230, and the fourth rewinding drum 240 are not the names of a fixed mechanism, but rather the names of the mechanism corresponding to the current state of the fixed machine position. That is to say, due to different processes, the same rewinding drum will sequentially "transform" into the third rewinding drum 230 during feeding, the second rewinding drum 220 during rewinding, the first rewinding drum 210 during cutting the finished product, and the fourth rewinding drum 240 during unloading, depending on the time and state of the process.

[0044] To achieve rapid unloading and avoid the problem of poor unloading efficiency caused by manual unloading, in this embodiment, the automated tape rewinding machine also includes an unloading mechanism 300. The unloading mechanism 300 includes a support base 310 and a material ejection assembly 320 movably connected to the support base 310. The unloading mechanism 300 also includes a first unloading cylinder and a second unloading cylinder 324. The first unloading cylinder drives the material ejection assembly 320 to reciprocate along the support base 310. Further, the material ejection assembly 320 includes a movable seat 321, a gripper 323 disposed on the movable seat 321, and a movable bracket 322 connecting the gripper 323 and the movable seat 321. The gripper 323 is movably connected to the fourth rewinding drum 240 to push the cut tape roll onto the unloading guide rail. The movable seat 321 is slidably connected to the support base 310. The second unloading cylinder 324 drives the movable bracket 322 to slidely connect with the movable seat 321 so that the gripper 323 fits against the fourth rewinding drum 240 to achieve unloading. It should be further explained that, since the rewinding drum is cylindrical and the tape bottom drum is also cylindrical, in order to better match the rewinding drum and the tape bottom drum to achieve efficient unloading, in this embodiment, the gripper 323 is arranged in an arc shape to match the rewinding drum and thus push the tape bottom drum.

[0045] Furthermore, to facilitate the tearing of the tape by the user, a paper strip is often placed near the cut edge of the tape near the cutting blade. Therefore, in this embodiment, the automated tape rewinding machine also includes a paper strip pasting mechanism 400. The paper strip pasting mechanism 400 includes a sticker guide rail 410, a sticker carriage 420 disposed on the sticker guide rail 410, and a paper receiving rod 600. The sticker guide rail 410 is provided with a groove 411. The sticker carriage 420 includes a sticker traction member, which is provided with a clamping mouth 421 that can move up and down.

[0046] The oral paper applicator 400 also includes a first sticker cylinder and a second sticker cylinder. The first sticker cylinder is connected to a sticker carriage 420 to drive the sticker carriage 420 to reciprocate along the slide groove 411 on the sticker guide rail 410. The second sticker cylinder is connected to a sticker traction member to attract and disconnect the sticker. Specifically, when the second sticker cylinder drives the clamp 421 to close, it attracts and grips the oral paper to pull it onto the paper receiving rod 600. When the oral paper is attached to the paper receiving rod 600, the receiving surface 610 on the paper receiving rod 600 receives the oral paper attracted by the sticker traction member, and the second sticker cylinder drives the clamp 421 to open, completing the traction. Then, the paper receiving rod 600 is rotated to attach the oral paper to the tape.

[0047] In summary, the automated tape rewinding machine in the above embodiments of this utility model integrates the equipment required for feeding, paper rolling, finished product cutting, and unloading processes into four rewinding drums within the same rewinding mechanism. This avoids separate setups, reduces the requirements for the work site, and offers high flexibility. Specifically, the rewinding mechanism includes four rewinding drums and four support rods. The rewinding drums are used to mount the tape bottom drum so that when the rewinding drums rotate, they drive the tape to be rewound onto the tape bottom drum. The four rewinding drums are arranged in a square interval. The rewinding mechanism also includes a central rotating shaft, which is located at the center of the layout of the four rewinding drums. The central rotating shaft drives the four rewinding drums to rotate along the central rotating shaft so that the positions of the four rewinding drums change periodically relative to the tape-cutting mechanism. The four support rods are staggered with the four rewinding drums, and the axis of the support rods is lower than the axis of the rewinding drums. When the tape-cutting mechanism presses down, it contacts the rewinding drums and support rods, thereby pressing the tape rewound onto the tape bottom drum so that the cutting blade can cut the tape, achieving separation of the rewound tape to obtain tape rolls.
