Description

Technical Field

[0001] This invention relates to the field of tape processing technology, and more specifically to a device for forming easy-tear ends after tape is wound up. Background Technology

[0002] Adhesive tape, as a commonly used packaging material, is widely used in daily office work, logistics packaging, and industrial production. To facilitate users tearing the tape by hand without the aid of external tools, a common design is to include easy-tear tabs at the ends of the tape roll. These tabs are typically formed by attaching paper, keeping the tape ends unbonded for easy tearing.

[0003] First, during the tape production process, long tape is wound into a large roll with a large diameter and width. During the winding process, easy-tear tabs are attached to the surface of the tape at predetermined intervals, so that multiple easy-tear tabs are distributed along the length of the final large roll. Then, the large roll is slit and rewound by a rewinding machine to form multiple small rolls that meet the specifications.

[0004] However, during the large roll winding process, the tape is in a transport state, and the attachment position of the easy-tear head is prone to shift as the tape is transported. If the easy-tear head is not completely attached to the tape, some areas may be lifted or not stuck, or the easy-tear head may be tilted, affecting the appearance of the product. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an easy-tear head forming device after tape winding, so as to solve the problem that in the background art, when the tape is in the transmission state, the attachment position of the easy-tear head is easily offset with the tape transmission. For example, the easy-tear head is not completely attached to the tape, resulting in some areas being lifted or not being stuck, or the easy-tear head is tilted at the bonding angle, which affects the appearance of the product.

The support frame is used to rigidly support the limit frame.

[0010] As a further embodiment of the present invention, the elastic component includes two symmetrically arranged L-shaped plates fixedly connected to the bottom of the top plate. Two symmetrical telescopic rods are fixedly connected to the top of the L-shaped plates. The other end of the telescopic rod is fixed to the limiting frame. A spring is sleeved on the outside of the telescopic rod, and the two ends of the spring contact the L-shaped plate and the limiting frame respectively.

[0011] As a further embodiment of the present invention, the limiting component includes a carrier fixedly connected to the top of the movable frame, a first hydraulic cylinder fixedly connected to the top of the carrier, the telescopic end of the first hydraulic cylinder passing through the carrier and fixedly connected to a housing, two symmetrically arranged limiting blocks fixedly connected to both sides of the housing, and an air suction component for adsorbing adhesive tape provided at the bottom of the housing.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Reference Figures 1-9This invention provides a tape roll forming device for easy-tear head, including a machine body 9. A plurality of guide rollers 10 are rotatably connected to one side of the machine body 9 via bearings. The plurality of guide rollers 10 are divided into upper and lower groups. The distance between the two guide rollers 10 in the upper group is smaller than the distance between the two guide rollers 10 in the lower group. The tape produced in the previous process is first passed under one of the lower guide rollers 10, then passed over the two upper guide rollers 10, and finally passed under the other lower guide roller 10. Then it is connected to a winding machine, which slowly winds up the tape. A first linear motor 11 is fixed to one side of the machine body 9 by bolts. A moving frame 12 is fixed to the top of the first linear motor 11 by bolts. The first linear motor 11 is used to drive the moving frame 12 to move synchronously at the speed of the conveyor belt, so that the conveyor belt and the moving frame 12 are relatively stationary. The top of the movable frame 12 is equipped with a second linear motor 13, and the top of the second linear motor 13 is fixed with a slide 14 by bolts.

[0031] It should be noted that the first linear motor 11 and the second linear motor 13 are both existing technologies, and those skilled in the art can set them according to actual needs, which will not be elaborated here.

[0032] A feeding assembly 3 for feeding paper is provided on one side of the carriage 14. The feeding assembly 3 includes two symmetrically arranged mounting rollers 302 that are rotatably connected to one side of the carriage 14 via bearings. One mounting roller 302 is used to mount the easy-tear head paper roll, and the other mounting roller 302 is used to mount the waste roll that rewinds the cut easy-tear head waste. The mounting roller 302 is provided with a first baffle 301 and a second baffle 303 at both ends. The first baffle 301 is fixedly connected to the mounting roller 302. The first baffle 301 and the second baffle 303 limit the paper roll installed on the mounting roller 302 to prevent the paper roll from shifting axially during rotation and ensure the stability of paper transmission. Multiple fixing blocks 304 are bolted to the upper surface of the carriage 14. A rotating roller 305 is rotatably connected between two adjacent fixing blocks 304 via a bearing. The two rotating rollers 305 are symmetrically arranged and located between two mounting rollers 302. After the paper is released from the easy-tear head paper roll, it passes over the two rotating rollers 305 sequentially (see reference). Figure 9 (As shown), and then connected to the waste roll, the paper is guided by two rotating rollers 305 to ensure that the paper remains flat during the transmission process; like Figure 9As shown, a drive assembly 4 for driving the rotating roller 305 of the waste roll to rotate is provided on one side of the slide 14. The drive assembly 4 includes a protective shell 404 fixed to one side of the slide 14 by bolts. One end of the rotating roller 305 of the waste roll passes through the slide 14 and is connected to a driven gear 403 by a key. A drive gear 402 that meshes with the driven gear 403 is rotatably connected to one side of the slide 14 by a bearing. The drive gear 402 is smaller than the driven gear 403. The drive gear 402 drives the driven gear 403 to rotate, thereby reducing the speed of the rotating roller 305 of the waste roll and preventing the paper from being torn due to excessive speed during the winding process. Both the driven gear 403 and the driving gear 402 are located inside the protective shell 404, which protects them. The drive motor 401, which drives the driving gear 402, is fixed to the outside of the protective shell 404 by bolts. When the drive motor 401 is started, it drives the driving gear 402 to rotate. The driving gear 402 meshes with the driven gear 403, which drives the rotating roller 305 of the waste roll to rotate, thereby achieving the traction of the paper and the winding of the waste.

[0033] It should be noted that the drive motor 401 is a servo motor with an encoder. The number of rotations and the rotation angle of the motor output shaft are controllable and highly accurate. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0034] like Figures 5-8 As shown, the upper surface of the carriage 14 is provided with a pressing and mounting assembly 5 for forming easy-tear tips and attaching them to the tape. The pressing and mounting assembly 5 includes a mounting bracket 501 fixed to the upper surface of the carriage 14 by bolts. A third hydraulic cylinder 502 is fixed to the top of the mounting bracket 501 by bolts. The telescopic end of the third hydraulic cylinder 502 passes through the mounting bracket 501 and is fixed to a connecting plate 503 by bolts. The third hydraulic cylinder 502 is used to drive the connecting plate 503 to move up and down. A rectangular cutting blade 504 is fixed to the lower surface of the connecting plate 503 by bolts. The length of the cutting blade 504 is equal to the width of the tape. The cutting blade 504 cuts the paper below into rectangular easy-tear tips that match the width of the tape. The bottom of the movable frame 12 is fixed with a fourth hydraulic cylinder 509 by bolts. The telescopic end of the fourth hydraulic cylinder 509 passes through the movable frame 12 and is fixed with a top plate 507 by bolts. The fourth hydraulic cylinder 509 is used to drive the top plate 507 to move up and down. A limit frame 505 is slidably connected to the outside of the top plate 507. A support frame 506 is provided on the side of the mounting frame 501 near the connecting plate 503. The support frame 506 is used to rigidly support the limit frame 505. The third hydraulic cylinder 502 is activated to drive the connecting plate 503 and the cutting blade 504 to move downward. When the cutting blade 504 contacts the paper, the limit frame 505 remains stationary under the support of the support frame 506. The third hydraulic cylinder 502 continues to extend, so that the cutting blade 504 passes through the paper, completes the cutting of the paper, forms an easy-tear head, and falls above the top plate 507. The size of the cutting blade 504 is the same as the size of the top plate 507, ensuring that the cut easy-tear head can fall completely on the top plate 507 without deviation or falling. After cutting is completed, the second linear motor 13 is started. The second linear motor 13 drives the slide 14 to move the mounting frame 501, connecting plate 503, cutting blade 504 and feeding assembly 3, so that the mounting frame 501, connecting plate 503, cutting blade 504 and feeding assembly 3 do not obstruct the upward movement of the top plate 507, forming a clearance (see reference). Figure 4 (As shown).

[0035] The top of the movable frame 12 is provided with a limiting component 1 for limiting the tape during easy-tear head application. The limiting component 1 includes a carrier frame 102 fixed to the top of the movable frame 12 by bolts. A first hydraulic cylinder 101 is fixed to the top of the carrier frame 102 by bolts. The telescopic end of the first hydraulic cylinder 101 passes through the carrier frame 102 and is fixed to a housing 104 by bolts. The stroke of the first hydraulic cylinder 101 causes the piston end to push the housing 104 down to contact the tape surface. Two symmetrically arranged limiting blocks 103 are fixed to both sides of the housing 104 by bolts. Through the cooperation of multiple limiting blocks 103, the left and right movement of the tape during the application process is limited, ensuring that the easy-tear head can be accurately attached to the preset position of the tape. like Figures 6-7 As shown, the bottom of the top plate 507 is provided with an elastic component 7 for pushing the limiting frame 505. The elastic component 7 includes two symmetrically arranged L-shaped plates 703 fixed to the bottom of the top plate 507 by bolts. The top of the L-shaped plates 703 is fixed with two symmetrical telescopic rods 701 by bolts. The other end of the telescopic rods 701 is fixed to the limiting frame 505. A spring 702 is sleeved on the outside of the telescopic rods 701. The two ends of the spring 702 are in contact with the L-shaped plates 703 and the limiting frame 505 respectively. First, start the first linear motor 11 to make the moving frame 12 move synchronously at the same speed as the tape conveyor, ensuring that the tape and the moving frame 12 are relatively stationary during the easy-tear head application process. Then, start the fourth hydraulic cylinder 509 to drive the top plate 507 to move upward. The top plate 507 drives the cut easy-tear head to move upward. At the same time, the first hydraulic cylinder 101 drives the housing 104 to move downward, so that the bottom of the housing 104 contacts the tape surface. Meanwhile, the top plate 507 drives the telescopic rod 701, spring 702 and limiting frame 505 to move upward through the L-shaped plate 703, so that the limiting frame 505 first contacts the bottom of the housing 104. At this time, the limiting frame 505 stops moving under the obstruction of the housing 104, while the top plate 507 continues to move upward under the drive of the fourth hydraulic cylinder 509. The telescopic rod 701 retracts and the spring 702 is compressed. Simultaneously, the top plate 507 pushes the easy-tear head upwards. The top plate 507 is located below the housing 104, ensuring that the easy-tear head can be accurately pushed to the lower surface of the tape during the application process, so that the easy-tear head can fully contact and adhere to the lower surface of the tape. This achieves precise application of the easy-tear head on the tape, solving the problem that the easy-tear head's attachment position is easily offset during tape transmission. It ensures that the easy-tear head can be completely adhered to the tape, avoiding situations where some areas are lifted or not adhered. After the application is completed, the fourth hydraulic cylinder 509 drives the top plate 507 to reset, and the spring 702 pushes the limit frame 505 to reset under its own elastic force. The first hydraulic cylinder 101 drives the housing 104 to reset, releasing the limit on the tape.

[0036] During the application process, the easy-tear head remains inside the limiting frame 505. The shape of the limiting frame 505 matches the shape of the easy-tear head. As the easy-tear head moves upward, the limiting frame 505 guides and limits its movement, preventing it from shifting or tilting. This further ensures the accuracy of the easy-tear head's application angle and avoids issues that could affect the product's appearance due to tilting. It also prevents the easy-tear head from deviating from its intended position due to wind or other external forces, ensuring that the easy-tear head always maintains the preset posture and position during application.

[0037] like Figure 8As shown, the bottom of the housing 104 is provided with an air suction component 6 for adsorbing the tape. The air suction component 6 includes a plurality of equally spaced air suction holes 602 opened at the bottom of the housing 104, and the air suction holes 602 penetrate the housing 104. A flexible hose 601 connected to the housing 104 is glued to the top of the housing 104. The other end of the flexible hose 601 is connected to an external negative pressure device. When the housing 104 is lowered to contact the surface of the tape under the drive of the first hydraulic cylinder 101, the external negative pressure device is activated. The flexible hose 601 and the air suction holes 602 generate an adsorption force on the tape, firmly adsorbing the tape to the bottom of the housing 104. This prevents the tape from shaking up and down during the transmission process and generating a certain amount of wind force, which will knock up the easy-tear head when it is close to the tape. At the same time, it can also avoid the position fluctuation of the tape due to its own tension, further improving the accuracy of easy-tear head application.

[0038] The second baffle 303 and the mounting roller 302 are detachably connected via a locking assembly 8. The locking assembly 8 includes a connecting block 803 fixed to one side of the second baffle 303 by bolts. A screw 802 is welded to the inner wall of one side of the connecting block 803. A threaded hole 801 is provided on one side of the mounting roller 302. The screw 802 is threadedly connected to the threaded hole 801, and the threaded hole 801 is concentric with the second baffle 303. By rotating the connecting block 803, the connecting block 803 rotates, causing the screw 802 to... Separating from the threaded hole 801 allows the second baffle 303 to be removed from the mounting roller 302, facilitating quick replacement of easy-tear paper rolls or waste rolls by operators and improving the efficiency of feeding and paper roll replacement. When a new paper roll needs to be installed, first place the paper roll on the mounting roller 302, then place the second baffle 303 on the end of the mounting roller 302, align the screw 802 on the connecting block 803 with the threaded hole 801, and tighten the screw 802 to fix the second baffle 303.

[0039] Above one of the guide rollers 10 on one side of the machine body 9, there is a re-pressure assembly 2 for pressing the easy-tear head after application. The re-pressure assembly 2 includes a fixing plate 201 fixed to one side of the machine body 9 by bolts. A second hydraulic cylinder 202 is fixed to the top of the fixing plate 201 by bolts. The telescopic end of the second hydraulic cylinder 202 passes through the fixing plate 201 and is fixed to a first connecting frame 203 by bolts. A pressure roller 204 is rotatably connected between the inner walls of the two sides of the first connecting frame 203 by bearings. Positioned directly above guide roller 10, and with the length of pressure roller 204 matching the width of the tape, when the tape with the easy-tear head attached passes through guide roller 10, the second hydraulic cylinder 202 is activated. The second hydraulic cylinder 202 drives the first connecting frame 203 and pressure roller 204 to move downward, so that pressure roller 204 contacts the tape surface and applies a certain pressure. Pressure roller 204 rotates under the drive of the tape, and performs secondary crushing on the attached easy-tear head to ensure that the easy-tear head is more firmly attached to the tape.

[0040] It should be noted that the first hydraulic cylinder 101, the second hydraulic cylinder 202, the third hydraulic cylinder 502 and the fourth hydraulic cylinder 509 in this application are all actuators in the hydraulic system. They achieve the telescopic function by cooperating with the hydraulic system, and achieve precise control of the telescopic displacement of the hydraulic cylinder piston rod by cooperating with magnetic switches, proximity switches or photoelectric switches. Those skilled in the art can set them according to actual needs, which will not be elaborated here.

[0041] Working principle of the invention: The tape produced in the previous process is first passed under one of the guide rollers 10 below, then over the two guide rollers 10 above, and finally over the other guide roller 10 below. Then it is connected to the winding machine, which slowly winds up the tape. The raw paper roll and the waste paper roll are respectively installed on two mounting rollers 302. Then, after the paper is released from the easy-tear head raw paper roll, it passes over the two rotating rollers 305 in sequence and then connects with the waste paper roll. The third hydraulic cylinder 502 is activated to drive the connecting plate 503 and the cutting blade 504 to move downward. When the cutting blade 504 contacts the paper, the limiting frame 505 remains stationary under the support of the support frame 506. The third hydraulic cylinder 502 continues to extend, allowing the cutting blade 504 to pass through the paper, complete the cutting of the paper, form an easy-tear head, and fall above the top plate 507. Start the second linear motor 13. The second linear motor 13 drives the slide 14 to move the mounting frame 501, connecting plate 503, cutting blade 504 and feeding assembly 3, so that the mounting frame 501, connecting plate 503, cutting blade 504 and feeding assembly 3 do not block the top plate 507 from moving upward, thus forming a clearance. Start the first linear motor 11 to make the moving frame 12 move synchronously at the same speed as the tape conveyor, ensuring that the tape and the moving frame 12 are relatively stationary during the easy-tear head application process. Then start the fourth hydraulic cylinder 509 to drive the top plate 507 to move upward, and the top plate 507 drives the cut easy-tear head to move upward. At the same time, the first hydraulic cylinder 101 drives the housing 104 to move downward, so that the bottom of the housing 104 contacts the surface of the tape. At the same time, the external negative pressure device is activated, and the tape is attracted by the hose 601 and the suction hole 602, so that the tape is firmly attracted to the bottom of the housing 104. At the same time, the top plate 507 drives the telescopic rod 701, spring 702 and limiting frame 505 to move upward through the L-shaped plate 703, so that the limiting frame 505 first contacts the bottom of the housing 104. At this time, the limiting frame 505 stops moving under the obstruction of the housing 104, while the top plate 507 continues to move upward under the drive of the fourth hydraulic cylinder 509. The telescopic rod 701 retracts, the spring 702 is compressed, and at the same time the top plate 507 pushes the easy-tear head upward, so that the easy-tear head fully contacts and adheres to the lower surface of the tape. Then the second hydraulic cylinder 202 is started. The second hydraulic cylinder 202 drives the first connecting frame 203 and the pressure roller 204 to move downward. The pressure roller 204 rotates under the drive of the tape, and performs secondary crushing on the attached easy-tear head. After the tape is applied, the fourth hydraulic cylinder 509 drives the top plate 507 to reset, the spring 702 pushes the limit frame 505 to reset under its own elastic force, the first hydraulic cylinder 101 drives the housing 104 to reset, releasing the limit on the tape, and then the first linear motor 11 drives the moving frame 12 to reset to the initial position, waiting for the next easy-tear head to be cut and applied. At the same time, the second linear motor 13 drives the slide 14 to reset, so that the feeding assembly 3 and the pressing and applying assembly 5 return to the initial working position. After resetting, start the drive motor 401. The drive motor 401 drives the drive gear 402 to rotate. The drive gear 402 meshes with the driven gear 403, which drives the rotating roller 305 of the waste roll to rotate, thereby pulling the original paper roll to release new paper and move the paper to the bottom of the cutting blade 504, preparing it for the next easy-tear head cut.
