Description

Technical Field

[0001] This utility model relates to the field of tape slitting machine technology, and in particular to a tape slitting machine that can stably clamp tape. Background Technology

[0002] Tape slitting machines are a sub-type of slitting machines. They are mainly used to cut wide rolls of tape (such as OPP, PVC, paper-based tape, etc.) into multiple narrow tapes using blades. The slitting size can be adjusted according to requirements to meet the application needs of different industries for small rolls of tape.

[0003] However, in practical applications, some problems remain unresolved. The following are some common issues with tape slitting machines: During slitting, the wide master roll of tape needs to be fixed. In most existing technologies, a single air shaft is used to fix the inner wall of the wide master roll. The centrifugal force and vibration generated when the cutting disc rotates can cause lateral displacement of the outer ring of the master roll, resulting in uneven tape width after slitting, or even serrated cuts. Tension control is also a concern. Without proper fixation of the outer ring, the tape is prone to localized loosening or tightening due to tension fluctuations during slitting, leading to dimensional deviations. The outer ring of the tape, affected by the traction force of the cutting disc, may wrinkle or curl at the edges due to uneven localized stress. Spiral patterns may also form between the layers of the outer ring of the master roll due to inertial sliding, affecting tape flatness and, in severe cases, causing loose winding or collapse.

Detailed Implementation

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Example 1

[0032] Reference Figures 1-3 This is the first embodiment of the present invention. This embodiment provides a tape slitting machine that can be stably clamped. The tape slitting machine includes a slitting mechanism 100 and a fixing mechanism 200. The slitting mechanism 100 can slit wide master roll tape, and the fixing mechanism 200 can fix the outer ring of the wide master roll tape.

[0033] Specifically, the slitting machine mechanism 100 includes a frame 101, on which a moving component 102 and an air shaft fixing component 103 are installed. The moving component 102 can drive the slitting component 104 to move, and the air shaft fixing component 103 can initially fix the roll of tape sleeved on its support shaft and drive it to rotate.

[0034] The moving component 102 has a slitting component 104 and a baffle 105 fixedly connected to its moving base. The moving component 102, the air shaft fixing component 103, and the slitting component 104 are all components of the tape slitting machine in the prior art. The working principle of this part is also prior art, which can be clearly understood by those skilled in the art, and will not be described in detail here. The baffle 105 can shield the tape during slitting, improve the safety during use, and reduce splashing.

[0035] Specifically, the fixing mechanism 200 is fixedly connected to the frame 101 and the moving component 102. It includes a support drive component 201 fixedly connected to the frame 101 and the moving component 102. Under the action of the moving seat of the moving component 102, the support drive component 201 can move the ring plate 202 and drive the rotating plate 204 to rotate, thereby adjusting the position of the clamping component 207 and realizing the switching of the tape fixing position and clamping fixation during slitting.

[0036] A ring plate 202 is fixedly connected to the support drive assembly 201. A slider 203 is slidably connected to the ring plate 202. A rotating plate 204 is rotatably connected to the surface of the ring plate 202. A guide post 205 is fixedly connected to the slider 203. A guide hole 206 is opened on the surface of the rotating plate 204 to cooperate with the guide post 205, and the guide post 205 is slidably connected inside it. The guide hole 206 is divided into two parts. The first part allows the slider 203 to move when the guide post 205 slides inside it. The second part does not allow the slider 203 to move when the guide post 205 slides inside it. The rotation of the rotating plate 204 causes the guide hole 206 to rotate and act on the guide post 205. In the first part, the guide post 205 is squeezed and moves, causing the slider 203 to move, bringing the multiple clamping assemblies 207 closer to the center, thereby fixing the tape.

[0037] As the tape gradually moves to the second part, the clamping component 207 does not change its function of fixing the tape as the rotating plate 204 rotates. This allows the slitting component 104 to be fixed as it gradually approaches the tape. Once the fixing is completed during the slitting process, no further pressure is applied. Similarly, the fixing is released when the tape is separated. The clamping component 207 is fixedly connected to the surface of the slider 203. The clamping component 207 fixes the outer ring of the roll tape, which is fixed to the air expansion shaft, thereby reducing the possibility of the outer ring becoming loose during slitting.

[0038] Example 2

[0039] Reference Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the support drive assembly 201 includes a drive component 201a and a transmission component 201b. The drive component 201a is mounted on the surface of the frame 101, the moving assembly 102, and the ring plate 202. With the drive component 201a, when the moving assembly 102 drives the slitting assembly 104 to change the slitting position, the ring plate 202, the rotating plate 204, and the clamping assembly 207 can move together, thereby fixing the outer ring of the tape at each slitting position.

[0041] The transmission component 201b is mounted on the surface of the rotating plate 204 and the driving component 201a. Through the setting of the transmission component 201b, when the moving component 102 drives the slitting component 104 to move and slitting, it can drive the rotating plate 204 to rotate, thereby causing the guide post 205, the slider 203 and the clamping component 207 to move, so that multiple clamping components 207 move closer to the tape and apply pressure to the outer circle of the tape to clamp and fix it.

[0042] The driving component 201a includes a support rod 201a-1 fixedly connected to the surface of the frame 101. A movable plate 201a-2 is sleeved on the surface of the support rod 201a-1 and fixedly connected to the ring plate 202. There are two support rods 201a-1, both fixedly connected to the surface of the frame 101. There are four movable plates 201a-2, each slidably connected to the surface of two support rods 201a-1. The ring plate 202 is fixedly supported by the movable plates 201a-2, so that it can only move along the axial direction of the support rods 201a-1.

[0043] A short block 201a-3 is fixedly connected to the movable plate 201a-2. A connecting frame 201a-4 is fixedly connected to the movable seat of the movable component 102. A sliding rod 201a-5 is fixedly connected to the connecting frame 201a-4 and is slidably connected to the short block 201a-3. The sliding rod 201a-5 passes through the short block 201a-3 and is slidably connected to it. When the cutting position is changed, the connecting frame 201a-4 moves with the movable seat, thereby driving the sliding rod 201a-5 to push the short block 201a-3 to move, thereby moving the movable plate 201a-2, the ring plate 202 and the components on it. During the cutting movement, the connecting frame 201a-4 moves with the movable seat towards the tape, thereby driving the sliding rod 201a-5 to slide on the short block 201a-3, without affecting its cutting trajectory.

[0044] A square plate 201a-6 is fixedly connected to one side of a movable plate 201a-2 and slidably connected to another movable plate 201a-2 on the same side. The square plate 201a-6 passes through one of the movable plates 201a-2 and is slidably connected to it. A fixing bolt 201a-7 is threaded onto the surface of the movable plate 201a-2. The movable plate 201a-2 and the square plate 201a-6 can be fixedly connected by the fixing bolt 201a-7.

[0045] One end of the fixing bolt 201a-7 contacts the surface of the square plate 201a-6. Through the setting of the square plate 201a-6 and the fixing bolt 201a-7, the distance between the two ring plates 202 on both sides can be adjusted and fixed, thereby adjusting the distance between the clamping components 207 on both sides to meet the cutting and fixing requirements under different conditions. At the same time, when one ring plate 202 moves, it can drive the other ring plate 202 to move.

[0046] The transmission component 201b includes a rotating column 201b-1 rotatably connected to the moving plate 201a-2. The rotating column 201b-1 is rotatably connected to the moving plate 201a-2 above via a bearing. A gear 201b-2 is sleeved on the surface of the rotating column 201b-1. A toothed plate 201b-3 is fixedly connected to the connecting frame 201a-4 and meshes with the gear 201b-2. A gear ring 201b-4 is fixedly connected to the rotating plate 204 and meshes with the gear 201b-2. Through the setting of the gear 201b-2, when cutting or completing the cutting and separation, the connecting frame 201a-4 moves, driving the toothed plate 201b-3 to move, which can drive it to rotate, thereby causing the gear ring 201b-4 to rotate, causing the rotating plate 204 to rotate and act on the guide column 205, causing the slider 203 and the clamping assembly 207 to move, completing the clamping and fixing and releasing the fixing.

[0047] One end of the rotating column 201b-1 is fixedly connected to a spline rod 201b-5, and is slidably connected to another rotating column 201b-1 on one side. The spline rod 201b-5 is fixedly connected to one rotating column 201b-1 and passes through the other rotating column 201b-1 and is slidably connected to it. By setting the spline rod 201b-5, the rotation of one rotating column 201b-1 can drive the other rotating column 201b-1 to rotate, so that the two gear rings 201b-4 on it rotate simultaneously, thereby driving the two rotating plates 204 together. Furthermore, adjusting the distance between the two ring plates 202 does not affect their movement, and they can still rotate together after the adjustment is completed.

[0048] The clamping assembly 207 includes a connecting block 207a fixedly connected to the surface of the slider 203. A movable bolt 207b is slidably connected to the connecting block 207a. Two movable bolts 207b slide through one connecting block 207a. The movable bolts 207b can move on the connecting block 207a. When the roller 207d on the housing 207c contacts the surface of the tape, it will not be obstructed as the connecting block 207a continues to move.

[0049] One end of the movable bolt 207b is fixedly connected to the housing 207c. The inner wall of the housing 207c is rotatably connected to the roller 207d. Multiple rollers 207d are rotatably connected to one housing 207c through bearings. The rollers 207d can fix the roll of tape after they are in close contact with the outer ring of the roll. At the same time, the tape can rotate normally when the air shaft fixing assembly 103 drives the tape to rotate and cut the circumference.

[0050] A spring 207e is fitted on the surface of the movable bolt 207b, and its two ends are fixedly connected to the surfaces of the connecting block 207a and the housing 207c, respectively. With the setting of the spring 207e, after the roller 207d contacts the surface of the tape, it gradually compresses as the connecting block 207a moves. Under the action of the elastic force of the spring 207e, it acts on the housing 207c and the roller 207d, thereby elastically fixing the outer ring of the roll of tape.

[0051] A motor 207f is fixedly connected to one side of the housing 207c, and its output shaft is fixedly connected to one end of the roller 207d. The motor 207f can drive the roller 207d to rotate, which plays the role of attachment drive when the slitting tape rotates circumferentially.

[0052] Limiting bolts 208 are fixedly connected to the ring plate 202. Four limiting bolts 208 are fixedly connected to one ring plate 202. The surface of the rotating plate 204 is provided with limiting holes 209 that cooperate with the limiting bolts 208, and the limiting bolts 208 are slidably connected in them. Four limiting holes 209 are provided on one rotating plate 204. Through the action of the limiting bolts 208 and the limiting holes 209, the rotating plate 204 is limited so that the rotating plate 204 can only rotate partially on the ring plate 202.

[0053] In use, the roll of tape is placed on the air shaft fixing assembly 103 and the protrusion on it is pneumatically fixed to the tape. The operation of the moving assembly 102 is controlled to make the slitting assembly 104 move and slit, which in turn makes the connecting frame 201a-4 drive the slide rod 201a-5 and the toothed plate 201b-3 to move, which in turn makes the toothed ring 201b-4 and the rotating plate 204 rotate, applying pressure to the guide post 205 and moving it from the first part on the guide hole 206 to the second part, which makes the slider 203 and the clamping assembly 207 move, so that multiple clamping assemblies 207 clamp and fix the tape.

[0054] As the slitting assembly 104 moves and rotates, the blades cut the tape. Then, by controlling the air shaft fixing assembly 103 to rotate the air shaft and controlling the operation of the motor 207f, the tape rotates to perform one round of slitting. After one section of slitting is completed, the moving seat on the slitting assembly 104 and the moving assembly 102 returns to its original position, thereby resetting the corresponding structure and releasing the clamping assembly 207 from the tape and releasing it from fixation.

[0055] Then, control the moving component 102 to move to the next cutting position. Under the action of the connecting frame 201a-4 and the slide bar 201a-5, the short block 201a-3, the moving plate 201a-2, the ring plate 202 and the components on it are moved to perform the next cutting operation, and so on in a cycle.

[0056] In summary, the fixing mechanism 200 can fix the outer ring of the wide master roll tape, which, compared with the prior art, reduces the probability of tape deviation, decreased slitting accuracy, wrinkles and curling, interlayer slippage and spiral patterns, and improves slitting quality and stability during slitting.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
