Description

Technical Field

[0001] This invention relates to the field of foam tape preparation technology, and in particular to an apparatus and method for preparing segmented tape rolls. Background Technology

[0002] Foam tape is made of EVA or PE foam as the base material, coated with solvent-based pressure-sensitive adhesive on one or both sides, and then covered with release paper. It has functions such as sealing, shock absorption, resistance to compression deformation, flame retardancy, and wetting. High-adhesion anti-mildew EVA foam tape is often processed by one-piece molding in the factory. The high-adhesion anti-mildew EVA foam tape produced is often in long rolls. In the later use process, it needs to be cut at a certain distance to split it into individual small rolls of high-adhesion anti-mildew EVA foam tape.

[0003] A search revealed Chinese patent application CN202210711738.3, which discloses a foam tape slitting device. The device includes a frame with a mounting base and a drive assembly for moving the mounting base towards or away from the tape winding roller. However, this technical solution lacks a mechanism to stop the circular blade in time. When cutting the foam tape, the blade easily contacts the roller as it moves towards the tape winding roller, causing irreversible damage. Therefore, it cannot stop the blade immediately after cutting the foam tape to avoid contact with the roller and subsequent damage. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a device and method for preparing segmented adhesive tape rolls.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A segmented adhesive tape roll preparation device includes a base plate. A first mounting plate and a first bracket are fixed to the top outer wall of the base plate. A first motor is fixed to one side outer wall of the first mounting plate. The output shaft of the first motor passes through one side outer wall of the first mounting plate. The output shaft of the first motor is connected to a first roll roller via a coupling. A feeding cylinder is inserted into the outer wall of the first roll roller. A limit ring is threadedly connected to the outer wall of the feeding cylinder. A foam tape roll is provided on the outer wall of the feeding cylinder. Movable frames are slidably connected to both sides outer walls of the base plate. Multiple cutters are fixed to one side outer wall of the movable frame. A collision sensing mechanism is provided on one side outer wall of the movable frame. A movable plate is fixed to the bottom outer wall of the movable frame. A rack plate is fixed to the top outer wall of the movable plate. An arc-shaped through groove is opened on one side outer wall of the first mounting plate. A guide wheel is slidably connected to the inner wall of the arc-shaped through groove. A push rod is rotatably connected to the inner wall of the guide wheel. A gear is fixed to one side outer wall of the push rod. The push rod and the output shaft of the first motor are connected by a transmission chain. A pushing mechanism is provided on one side outer wall of the first mounting plate.

[0007] Preferably, a second mounting plate is fixed to the top outer wall of the base plate, and a control panel is fixed to one side outer wall of the second mounting plate. The first motor and the control panel are electrically connected.

[0008] Furthermore: the pushing mechanism includes an electric push rod, a connecting groove, an L-shaped push plate, and a top plate. The electric push rod is fixed to the top outer wall of the base plate, the top plate is fixed to one side outer wall of the first mounting plate, the connecting groove is provided on the top outer wall of the base plate, the L-shaped push plate is slidably connected to the inner wall of the top plate and the connecting groove, the output shaft of the electric push rod is fixed to one side outer wall of the L-shaped push plate, and the electric push rod is electrically connected to the control panel.

[0009] A further preferred embodiment: the collision sensing mechanism includes a movable frame, a collision sensor, and a support rod. The movable frame is slidably connected to the outer wall of the movable frame, the collision sensor is fixed to the inner wall of one side of the movable frame, and the support rod is fixed to the outer wall of one side of the movable frame.

[0010] As a preferred embodiment of the present invention: a second motor is fixed to the outer wall of the second mounting plate, the output shaft of the second motor passes through one side of the outer wall of the second mounting plate, a second roll roller is inserted into the outer wall of the output shaft of the second motor, a take-up cylinder is slidably connected to the outer wall of the second roll roller, a second bracket is fixed to the top outer wall of the bottom plate, the second roll roller is rotatably connected to the top outer wall of the second bracket, and the second motor is electrically connected to the control panel.

[0011] As a further preferred embodiment of the present invention: fixing plates are respectively fixed on the outer walls of both sides of the receiving cylinder, and the fixing plates are fixed to the outer wall of the second roll roller by screws.

[0012] As a further embodiment of the present invention: the outer wall of the feeding cylinder has multiple reserved annular grooves, the top outer wall of the first bracket and the second bracket is fixed with a support seat, the top outer wall of the support seat is fixed with an arc-shaped card plate by screws, and the second winding roller and the feeding cylinder are respectively rotatably connected to the inner wall of the support seat and the arc-shaped card plate.

[0013] Based on the aforementioned scheme: a friction strip is fixed to one side of the outer wall of the movable plate, a friction block is slidably connected to the inner wall of the connecting groove, a conical block is fixed to one side of the outer wall of the friction block, and a spring is fixed to the outer wall of the conical block and the connecting groove on opposite sides.

[0014] Based on the aforementioned scheme, the preferred embodiment is as follows: a limiting frame is fixed to one side of the outer wall of the L-shaped push plate, the push rod is slidably connected to the inner wall of the limiting frame, an L-shaped plate is fixed to one side of the outer wall of the bottom plate, and the bottom outer wall of the movable frame is slidably connected to the L-shaped plate.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. When the cutting blade is about to contact the feeding cylinder of the wound foam tape roll, the collision sensing mechanism on the side of the movable frame will contact the limiting ring on the outer wall of the feeding cylinder. At this time, the collision sensing mechanism will send an electrical signal to the control panel. The control panel will control the pushing mechanism on the side of the first mounting plate to push the push rod forward. When the push rod moves forward, it will move in an arc shape under the guidance of the arc-shaped through groove and the guide wheel, driving the gear on one side to move upward relative to the rack plate by a certain distance, disengaging the meshing connection between the gear and the rack plate. While the first motor continues to drive the foam tape roll to rotate, the movable frame as a whole will not move forward. This avoids the cutting blade on one side of the movable frame from contacting the outer wall of the feeding cylinder and continuing to move forward, which would damage the feeding cylinder. While the cutting blade fully cuts the rotating foam tape roll, it avoids irreversible damage to the rotating feeding cylinder, thus improving the stability of the preparation device during operation.

[0017] 2. When the collision sensing mechanism sends a collision signal to the control panel, the control panel will control the electric push rod to push the L-shaped push plate forward. The L-shaped push plate will then push the push rod, which is slidably connected to the guide wheel inside the arc-shaped groove, to slide along the arc-shaped groove. This will quickly raise the height of the gear, disengage the gear and the rack plate, and prevent the rotating gear from continuing to drive the cutter forward through the rack plate. This allows the cutter to thoroughly cut the rotating foam tape roll while avoiding damage to the rotating feed cylinder.

[0018] 3. As the movable frame moves forward, the support rod on one side of the movable frame will collide with the limiting ring on the outer wall of the feeding cylinder. After the support rod contacts the limiting ring, the continuously moving movable frame will press against the collision sensor on the inner wall of one side of the movable frame. At this time, the cutter on one side of the movable frame will also move to the outer wall of the feeding cylinder. The collision sensor will then send an electrical signal to the control panel, which will cause the control panel to quickly control the push mechanism to push the gear away from the top of the rack plate, preventing the movable frame from continuing to drive the cutter forward.

[0019] 4. After the worker removes the arc-shaped clamp from the top of the support base, the feeding cylinder can be taken out from one side of the first roll of material. At the same time, the second roll of material is pulled out from the output shaft of the second motor. The reserved annular groove can prevent the cutter passing through the foam tape roll from directly contacting the rotating feeding cylinder, further improving the stability of the cutter when cutting the foam tape roll.

[0020] 5. When the pushing mechanism pushes the L-shaped push plate forward, the L-shaped push plate will contact the conical block. As the conical block continues to move forward, the L-shaped push plate will push the friction block to one side of the movable plate through the conical block. When the electric push rod pushes the guide wheel to slide to the inner wall of the arc-shaped through groove through the L-shaped push plate, the friction block will also move to the side of the friction strip under the push of the conical block. Thus, the movable frame is fixed by the friction between the friction block and the friction strip, improving the stability of the cutter when cutting the foam tape roll. Attached Figure Description

[0030] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0031] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0032] Example 1:

[0033] An apparatus for preparing segmented adhesive tape rolls, such as Figure 1-8As shown, the system includes a base plate 1. A first mounting plate 13 and a first bracket 19 are fixed to the top outer wall of the base plate 1. A first motor 12 is fixed to one side of the outer wall of the first mounting plate 13. The output shaft of the first motor 12 passes through one side of the outer wall of the first mounting plate 13. The output shaft of the first motor 12 is connected to a first roll roller 37 via a coupling. A feed cylinder 21 is inserted into the outer wall of the first roll roller 37. A limit ring 31 is threadedly connected to the outer wall of the feed cylinder 21. A roll of foam tape 14 is provided on the outer wall of the feed cylinder 21. Movable frames 17 are slidably connected to the outer walls of both sides of the base plate 1. Multiple cutters 16 are fixed to one side of the outer wall of the movable frame 17. A collision sensing mechanism is provided. A movable plate 2 is fixed to the bottom outer wall of the movable frame 17, and a rack plate 3 is fixed to the top outer wall of the movable plate 2. An arc-shaped through groove 4 is opened on one side of the outer wall of the first mounting plate 13. A guide wheel 22 is slidably connected to the inner wall of the arc-shaped through groove 4. A push rod 23 is rotatably connected to the inner wall of the guide wheel 22. A gear 5 is fixed to one side of the outer wall of the push rod 23. The push rod 23 and the output shaft of the first motor 12 are connected by a transmission chain. A pushing mechanism is provided on one side of the outer wall of the first mounting plate 13. A second mounting plate 7 is fixed to the top outer wall of the base plate 1. A control panel 8 is fixed to one side of the outer wall of the second mounting plate 7. The first motor 12 and the control panel 8 are electrically connected.

[0034] The operator winds the foam tape roll 14, which needs to be cut, onto the feeding cylinder 21. The feeding cylinder 21 is then inserted into the first roll roller 37. The operator then starts the first motor 12 via the control panel 8, causing the foam tape roll 14 to rotate. Simultaneously, the first motor 12 drives the gear 5 via a transmission chain, which in turn drives the meshing rack plate 3 forward. This allows the first motor 12 to stably push the movable plate 2 and the movable frame 17 forward while rotating the foam tape roll 14. This allows multiple cutters 16 on one side of the movable frame 17 to continuously approach the rotating foam tape roll 14 and cut it. When one side of the cutter 16 is about to contact the feeding cylinder 21 winding the foam tape roll 14, a collision sensing mechanism located on one side of the movable frame 17 will contact the limiting ring 31 on the outer wall of the feeding cylinder 21. At this time, the collision sensing mechanism sends an electrical signal to the control panel 8. The control panel 8 controls the pushing mechanism located on one side of the first mounting plate 13 to push the push rod 23 forward. When the push rod 23 moves forward, it will move in an arc shape under the guidance of the arc-shaped through groove 4 and the guide wheel 22, thereby driving the gear 5 on one side to move upward relative to the rack plate 3 by a certain distance, thereby disengaging the meshing connection between the gear 5 and the rack plate 3. While the first motor 12 continues to drive the foam tape roll 14 to rotate, the entire movable frame 17 stops moving forward. This prevents the cutter 16 on one side of the movable frame 17 from contacting the outer wall of the feeding cylinder 21 and continuing to move forward, causing damage to the feeding cylinder 21. Thus, while the cutter 16 fully cuts the rotating foam tape roll 14, it avoids the cutter 16 causing irreversible damage to the rotating feeding cylinder 21, improving the stability of the preparation device during operation.

[0035] like Figure 1-4 As shown, the pushing mechanism includes an electric push rod 6, a connecting groove 24, an L-shaped push plate 27, and a top plate 26. The electric push rod 6 is fixed to the top outer wall of the base plate 1, the top plate 26 is fixed to one side outer wall of the first mounting plate 13, the connecting groove 24 is disposed on the top outer wall of the base plate 1, the L-shaped push plate 27 is slidably connected to the inner wall of the top plate 26 and the connecting groove 24, the output shaft of the electric push rod 6 is fixed to one side outer wall of the L-shaped push plate 27, and the electric push rod 6 is electrically connected to the control panel 8. When the collision sensing mechanism sends a collision signal to the control panel 8, the control... Panel 8 controls the electric push rod 6 to push the L-shaped push plate 27 forward, thereby pushing the push rod 23, which is slidably connected to the arc-shaped through groove 4 by the guide wheel 22, to slide along the arc-shaped through groove 4. This quickly raises the height of the gear 5, disengaging the meshing connection between the gear 5 and the rack plate 3. This prevents the rotating gear 5 from continuing to drive the cutter 16 forward through the rack plate 3, allowing the cutter 16 to thoroughly cut the rotating foam tape roll 14 while avoiding damage to the rotating feed cylinder 21.

[0036] like Figure 5 As shown, the collision sensing mechanism includes a movable frame 33, a collision sensor 34, and a support rod 15. The movable frame 33 is slidably connected to the outer wall of the movable frame 17, the collision sensor 34 is fixed to the inner wall of one side of the movable frame 33, and the support rod 15 is fixed to the outer wall of one side of the movable frame 33. As the movable frame 17 moves forward, the support rod 15 on one side of the movable frame 33 will collide with the limiting ring 31 on the outer wall of the feeding cylinder 21. When the support rod 15 contacts the limiting ring 31, the moving movable frame 17 will squeeze the collision sensor 34 on the inner wall of one side of the movable frame 33. At this time, the cutter 16 on one side of the movable frame 17 will also move to the outer wall of the feeding cylinder 21. At this time, the collision sensor 34 will send an electrical signal to the control panel 8, so that the control panel 8 can quickly control the push mechanism to push the gear 5 away from the top of the rack plate 3, so as to prevent the movable frame 17 from continuing to drive the cutter 16 forward.

[0037] like Figure 1 , Figure 2 and Figure 6 As shown, a second motor 9 is fixed to the outer wall of the second mounting plate 7. The output shaft of the second motor 9 passes through one side of the outer wall of the second mounting plate 7. A second winding roller 20 is inserted into the outer wall of the output shaft of the second motor 9. A take-up cylinder 10 is slidably connected to the outer wall of the second winding roller 20. A second bracket 11 is fixed to the top outer wall of the base plate 1. The second winding roller 20 is rotatably connected to the top outer wall of the second bracket 11. The second motor 9 is electrically connected to the control panel 8. Fixing plates 38 are fixed to the outer walls of both sides of the take-up cylinder 10. The fixing plates 38 are fixed to the second winding roller 20 by screws. On the outer wall; after the worker cuts the foam tape roll 14 into segments using the cutter 16, the control panel 8 will control the push mechanism to reset, so that the gear 5 re-engages with the rack plate 3. Then, the first motor 12 is controlled to drive the foam tape roll 14 to rotate in the opposite direction, so that the cutter 16 is reset through the gear 5 and the rack plate 3. Then, the worker can wrap one end of the foam tape roll 14 around the corresponding take-up cylinder 10 and control the second motor 9 and the first motor 12 to rotate in the same direction to wind and recycle the cut foam tape roll 14, thus completing the cutting and preparation of the foam tape roll.

[0038] like Figure 5-6As shown, the outer wall of the feeding cylinder 21 has multiple reserved annular grooves 32. The top outer wall of the first bracket 19 and the second bracket 11 is fixed with a support base 35. The top outer wall of the support base 35 is fixed with an arc-shaped clamping plate 36 by screws. The second roll roller 20 and the feeding cylinder 21 are respectively rotatably connected to the inner wall of the support base 35 and the arc-shaped clamping plate 36. After the operator removes the arc-shaped clamping plate 36 from the top of the support base 35, the feeding cylinder 21 can be taken out from one side of the first roll roller 37. At the same time, the second roll roller 20 is pulled out from the output shaft of the second motor 9. The reserved annular grooves 32 can prevent the cutter 16 passing through the foam tape roll 14 from directly contacting the rotating feeding cylinder 21, further improving the stability of the cutter 16 when cutting the foam tape roll 14.

[0039] like Figure 3-4 As shown, a friction strip 25 is fixed to one side of the outer wall of the movable plate 2, and a friction block 30 is slidably connected to the inner wall of the connecting groove 24. A conical block 28 is fixed to one side of the outer wall of the friction block 30, and a spring 29 is fixed to the outer wall of the conical block 28 and the connecting groove 24 on opposite sides. When the pushing mechanism pushes the L-shaped push plate 27 forward, the L-shaped push plate 27 will contact the conical block 28. As the conical block 28 continues to move forward, the L-shaped push plate 27 will push the friction block 30 to one side of the movable plate 2 through the conical block 28. When the electric push rod 6 pushes the guide wheel 22 to slide to one side of the inner wall of the arc-shaped through groove 4 through the L-shaped push plate 27, the friction block 30 will also move to the side of the friction strip 25 under the push of the conical block 28. Thus, the movable frame 17 is fixed by the friction between the friction block 30 and the friction strip 25, thereby improving the stability of the cutter 16 when cutting the foam tape roll 14.

[0040] like Figure 7 As shown, a limiting frame 39 is fixed to one side of the outer wall of the L-shaped push plate 27, and the push rod 23 is slidably connected to the inner wall of the limiting frame 39. An L-shaped plate 18 is fixed to one side of the outer wall of the base plate 1, and the bottom outer wall of the movable frame 17 is slidably connected to the L-shaped plate 18. The limiting frame 39 can limit and guide the push rod 23 on one side of the L-shaped push plate 27, so that the L-shaped push plate 27 can better drive the push rod 23 to move back and forth.

[0041] In this embodiment, during use, the operator winds the foam tape roll 14 to be cut onto the feeding cylinder 21, then inserts the feeding cylinder 21 onto the first roll roller 37. The operator then starts the first motor 12 via the control panel 8, causing the foam tape roll 14 to rotate. Simultaneously, the first motor 12, while rotating, also drives the gear 5 via a transmission chain, which in turn drives the meshing rack plate 3 forward. This allows the first motor 12 to stably push the movable plate 2 and the movable frame 17 forward while rotating the foam tape roll 14, enabling multiple cutters 16 on one side of the movable frame 17 to continuously approach the rotating foam tape roll 14 and cut it. When one side of the cutter 16 is about to contact the feeding cylinder winding the foam tape roll 14... When contact occurs, the collision sensing mechanism located on one side of the movable frame 17 will contact the limiting ring 31 on the outer wall of the feeding cylinder 21. At this time, the collision sensing mechanism will send an electrical signal to the control panel 8. The control panel 8 will control the pushing mechanism located on one side of the first mounting plate 13 to push the push rod 23 forward. When the push rod 23 moves forward, it will move in an arc shape under the guidance of the arc-shaped through groove 4 and the guide wheel 22, thereby driving the gear 5 on one side to move upward relative to the rack plate 3 by a certain distance, thereby disengaging the meshing connection between the gear 5 and the rack plate 3. While the first motor 12 continues to drive the foam tape roll 14 to rotate, the movable frame 17 as a whole will not move forward, thus preventing the cutter 16 on one side of the movable frame 17 from contacting the outer wall of the feeding cylinder 21 and continuing to move forward, causing damage to the feeding cylinder 21.

[0042] When the collision sensing mechanism sends a collision signal to the control panel 8, the control panel 8 controls the electric push rod 6 to push the L-shaped push plate 27 forward. The L-shaped push plate 27 then pushes the push rod 23, which is slidably connected to the guide wheel 22 inside the arc-shaped through groove 4, to slide along the arc-shaped through groove 4. This quickly raises the height of the gear 5, disengaging the meshing connection between the gear 5 and the rack plate 3. As the rotating gear 5 is prevented from continuing to drive the cutter 16 forward via the rack plate 3, the moving frame 17 continues to move forward. The support rod 15 on one side of the moving frame 33 collides with the limiting ring 31 on the outer wall of the discharge cylinder 21. When the support rod 15 contacts the limiting ring 31, the moving frame 17, which continues to move forward, presses against the collision sensor 34 on the inner wall of one side of the moving frame 33. At this time, the cutter 16 on one side of the moving frame 17 also moves to the outer wall of the discharge cylinder 21. The collision sensor 34 then sends an electrical signal to the control panel 8, causing the control panel 8 to quickly control the push mechanism to run.

[0043] After the worker cuts the foam tape roll 14 into segments using the cutter 16, the control panel 8 controls the push mechanism to reset, thereby allowing the gear 5 to re-engage with the rack plate 3. Then, the first motor 12 is controlled to drive the foam tape roll 14 to rotate in the opposite direction, thereby driving the cutter 16 to reset through the gear 5 and the rack plate 3. The worker can then wrap one end of the foam tape roll 14 around the corresponding take-up cylinder 10 and control the second motor 9 and the first motor 12 to rotate in the same direction to wind and recycle the cut foam tape roll 14, completing the cutting and preparation of the foam tape roll.

[0044] Example 2:

[0045] A method for preparing segmented adhesive tape rolls, such as... Figure 1-8 As shown, it includes the following steps:

[0046] S1: The staff winds the foam tape roll 14 that needs to be cut and prepared onto the feeding cylinder 21, then inserts the feeding cylinder 21 onto the first roll roller 37, and fixes the arc-shaped clamping plate 36 onto the support base 35 with screws.

[0047] S2: The staff controls the first motor 12 through the control panel 8 to drive the foam tape roll 14 to rotate, and cuts the foam tape roll 14 into sections through the cutter 16;

[0048] S3: The staff inserts the corresponding number of take-up cylinders 10 into the corresponding positions on the outer wall of the second roll roller 20 and fixes them with screws. Then, the second roll roller 20 is inserted into the output shaft side of the second motor 9.

[0049] S4: The worker winds the segmented foam tape roll 14 onto the take-up cylinder 10, and then controls the first motor 12 and the second motor 9 to rotate in the same direction at a uniform speed through the control panel 8, so as to drive the take-up cylinder 10 to take up the segmented foam tape roll 14.

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
