Description

Technical Field

[0001] This utility model belongs to the technical field of tape slitting devices, specifically a tape production roll slitting device. Background Technology

[0002] As a widely used adhesive material in industry, commerce, and daily life, the market demand for adhesive tape is increasing year by year. With the advancement of technology and the diversification of market demands, the adhesive tape industry has increasingly higher requirements for product quality and performance. In the industrial field, adhesive tape is used for product packaging and component fixing; in the commercial field, it is used for goods sealing and labeling; and in daily life, it is used for item pasting and repair. Different fields have different requirements for the specifications and performance of adhesive tape, which necessitates precise slitting and processing during the adhesive tape production process.

[0003] Traditional tape slitting is typically inefficient: Early tape slitting devices often used a single cutter. When slitting the tape roll, the cutter needed to be moved multiple times to complete the cuts, consuming a significant amount of time and resulting in low efficiency. For example, some small tape factories used manual slitting equipment that could only cut one strip of tape at a time, requiring manual readjustment of the cutter position before the next cut, leading to extremely low production efficiency. Furthermore, precision is low: during the slitting process, manual operation or simple mechanical devices cannot guarantee cutting precision. Deviations in cut width may occur, resulting in inconsistent tape specifications and affecting product quality and performance.

[0004] Therefore, in order to solve the above problems, it is necessary to develop a high-efficiency and high-precision tape production roll slitting device. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] like Figures 1 to 2 As shown in the embodiment of this utility model, a tape production roll slitting device includes a worktable 1: an unwinding mechanism is mounted on the top of the worktable 1; a slitting mechanism is mounted on the top of the worktable 1; a winding mechanism is mounted on the top of the worktable 1; a guiding mechanism is mounted on the top of the worktable 1; a meter counting mechanism is mounted on the top of the winding mechanism; and a tension adjusting mechanism is mounted on the top of the guiding mechanism. During operation, the tape master roll is hoisted onto the unwinding mechanism, adjusted to a suitable position using an adjusting device, and the tape end is led out and guided to the slitting mechanism via the guiding mechanism. The position and parameters of the cutters are adjusted according to the preset slitting width. After starting the equipment, the unwinding mechanism releases the tape at a uniform speed, which is then slid out by the slitting mechanism. The tape is cut into multiple narrow strips. The slit tapes are guided by a guiding mechanism to a winding mechanism, which winds them up according to a set winding speed and length. During the winding process, a tension adjustment mechanism and a meter counting mechanism ensure the quality and length accuracy of the tape winding. When the set roll diameter or length is reached, the equipment automatically stops, and the operator removes the wound tape roll from the winding mechanism, completing one slitting operation. Through the above structure, high-precision control of the tape slitting width can be achieved through precise cutter adjustment and tension control. The slitting tape has neat edges, no burrs, and good quality. High-speed slitting can be achieved, greatly improving the efficiency of tape production and meeting the needs of large-scale production.

[0024] like Figure 3As shown, the slitting mechanism includes a slide groove 2, forward and reverse screws 21, a moving block 22, a blade holder 23, a first motor 24, a first rotating shaft 25, and a circular blade 26; the slide groove 2 is fixed to the top of the worktable 1; the forward and reverse screws 21 are installed in the middle of the slide groove 2; the moving block 22 is screwed to the middle of the forward and reverse screws 21; the blade holder 23 is fixed to the top of the moving block 22; the first motor 24 is fixed to the side wall of the blade holder 23; the output end of the first motor 24 is rotatably connected to the first rotating shaft 25, and the first rotating shaft 25 passes through the side wall of the blade holder 23; A circular blade 26 is fixedly connected to the middle of the first rotating shaft 25. During operation, when the tape is guided to the top of the slitting mechanism, the first motor 24 is started, causing the first rotating shaft 25 to drive the circular blade 26 to rotate. Then, the moving block 22 slides on the forward and reverse screws 21, causing the blade holder 23 to move in the middle of the slide groove 2, thereby driving the circular blade 26 to slit the tape. Through the above structure, the circular blade 26 can be effectively made to rotate at high speed under the drive of the first motor 24 and then reciprocate to cut the tape. The cutting width is determined by the spacing of the circular blades 26 or the adjustment device.

[0025] like Figure 1 As shown, the unwinding mechanism includes an unwinding frame 3, a second motor 31, and a take-up / unwinding shaft 8. A set of unwinding frames 3 is fixedly connected to the top of the workbench 1. The take-up / unwinding shaft 8 is rotatably connected to the middle of the set of unwinding frames 3. The second motor 31 is fixedly connected to the side wall of the unwinding frame 3, and the output end of the second motor 31 passes through the unwinding frame 3 and is rotatably connected to the end of the take-up / unwinding shaft 8. During operation, when the tape is placed in the middle of the take-up / unwinding shaft 8, the second motor 31 on the side wall of the unwinding frame 3 is activated to drive the take-up / unwinding shaft 8 to rotate, thereby unwinding the tape. Through the above structure, the tape can be unwound at a uniform speed by the drive of the motor, which improves the practicality of tape unwinding.

[0026] like Figure 2 As shown, the guiding mechanism includes a vertical plate 4, a conveyor belt 41, a third motor 42, and guide rollers 43. The top of the worktable 1 is fixedly connected to the vertical plate 4. The third motor 42 is fixedly connected to the side wall of the vertical plate 4. Multiple sets of guide rollers 43 are rotatably connected to the side wall of the vertical plate 4, and the output end of the third motor 42 passes through the vertical plate 4 and connects to the end of the guide rollers 43. The conveyor belt 41 is slidably connected to the middle of the guide rollers 43. During operation, when the conveyor belt is unwound from the unwinding mechanism, the third motor 42 on the side wall of the vertical plate 4 is activated, causing it to drive the guide rollers 43 to rotate towards the winding mechanism. The guide rollers 43 then drive the conveyor belt 41, thereby guiding the conveyor belt that falls on the conveyor belt 41 towards the winding mechanism. The above structure can be used to guide the running direction of the conveyor belt during the unwinding, slitting, and winding processes, ensuring that the conveyor belt always moves along the predetermined path, preventing the conveyor belt from deviating, thereby achieving automated operation, reducing manual intervention, and reducing labor intensity.

[0027] like Figure 4 As shown, the winding mechanism includes a winding frame 5, a fourth motor 51, and a take-up and unwinding shaft 8. A set of winding frames 5 is fixedly connected to the top of the workbench 1. The take-up and unwinding shaft 8 is rotatably connected to the middle of the set of winding frames 5. The fourth motor 51 is fixedly connected to the side wall of the winding frame 5, and the output end of the fourth motor 51 passes through the winding frame 5 and is rotatably connected to the end of the take-up and unwinding shaft. During operation, when the tape is transmitted to the middle of the take-up and unwinding shaft 8 after being slit, the fourth motor 51 on the side wall of the winding frame 5 is activated, causing the take-up and unwinding shaft 8 to rotate and wind up. Through the above structure, the take-up and unwinding shaft 8 can be driven by a motor, and the speed can be independently controlled to achieve constant linear speed winding under different roll diameters. It can also realize the quick replacement and positioning of the take-up and unwinding shaft 8.

[0028] like Figure 4 As shown, the meter-counting mechanism includes a photoelectric sensor 6 and a crossbar 61; the photoelectric sensor 6 is fixedly connected to the top of the winding frame 5; the bottom end of the photoelectric sensor 6 is fixedly connected to the crossbar 61; during operation, when the tape is wound up, the length of the wound tape is accurately measured by the photoelectric sensor 6 and the crossbar 61. Through the above structure, the winding mechanism can automatically stop winding or perform a roll change operation when the tape reaches the set length.

[0029] like Figure 3 As shown, the tension adjustment mechanism includes a triangular pressure block 7 and a second rotating shaft 71; the second rotating shaft 71 is rotatably connected to the side wall of the vertical plate 4; the triangular pressure block 7 is fixedly connected to the middle of the second rotating shaft 71; during operation, when the conveyor belt is conveyed by the guide mechanism, the triangular pressure block 7 is pressed onto the conveyor belt at the top of the conveyor belt 41 by rotating the second rotating shaft 71 to control its tension. Through the above structure, the tension of the conveyor belt during unwinding can be detected and controlled, ensuring tension stability and improving the stability of the slitting device.

[0030] like Figure 1 As shown, an anti-slip sleeve is fixedly connected to the middle of the unwinding and winding shaft 8. During operation, when the tape is unwinding and winding, the anti-slip sleeve prevents the tape roll from slipping during the unwinding process. The above structure can reduce the decrease in cutting accuracy caused by slippage of the tape during unwinding and winding, and improve the accuracy of the slitting device.

[0031] During operation, the master roll of adhesive tape is hoisted onto the unwinding mechanism. The adjustment device positions it appropriately, and the tape end is led out and guided to the slitting mechanism via the guide mechanism. The position and parameters of the cutters are adjusted according to the preset slitting width. After starting the equipment, the unwinding mechanism releases the tape at a uniform speed. The slitting mechanism cuts the tape into multiple narrow strips. The slit tapes are then guided to the winding mechanism by the guide mechanism. The winding mechanism winds the tape according to the set winding speed and length. During winding, the tension adjustment mechanism and meter counting mechanism ensure the quality and length accuracy of the tape winding. When the set roll diameter or length is reached, the equipment automatically stops. The operator removes the wound tape roll from the winding mechanism, completing the process. In a single slitting operation, the aforementioned structure allows for precise control of the tape slitting width through accurate tool adjustment and tension control. The slitting tape has clean, burr-free edges, resulting in high quality. High-speed slitting significantly improves tape production efficiency, meeting the demands of large-scale production. When the tape is guided to the top of the slitting mechanism, the first motor 24 is activated, causing the first rotating shaft 25 to drive the circular blade 26 to rotate. Subsequently, the moving block 22 slides on the forward and reverse screws 21, causing the tool holder 23 to move in the middle of the slide groove 2, thereby driving the circular blade 26 to slit the tape. This structure effectively enables the circular blade 26 to rotate at high speed under the drive of the first motor 24 and then reciprocate, cutting the tape. The cut width is determined by the spacing of the circular blades 26 or by an adjustment device. When the tape is placed in the middle of the take-up and unwrap shaft 8, the second motor 31 on the side wall of the unwrap frame 3 drives the take-up and unwrap shaft 8 to rotate, causing the tape to unwrap. This structure allows the tape to be unwrapped at a uniform speed by the motor drive, improving the practicality of tape unwinding. When the tape is unwrapped from the unwinding mechanism, the third motor 42 on the side wall of the vertical plate 4 is activated, causing it to drive the guide roller 43 to rotate towards the take-up mechanism. The guide roller 43 then drives the conveyor belt 41, thus the tape falling on the conveyor belt 41 is guided towards the take-up mechanism. This structure can be used to guide the running direction of the tape during the unwinding, slitting, and take-up processes, ensuring that the tape always runs along the predetermined path. The path movement is controlled to prevent the tape from deviating, thus achieving automated operation, reducing manual intervention and labor intensity. When the tape is conveyed to the middle of the take-up and unwind roll 8 after being slit, the fourth motor 51 on the side wall of the take-up frame 5 is activated, causing the take-up and unwind roll 8 to rotate and wind up. Through the above structure, the take-up and unwind roll 8 can be driven by a motor and its speed can be independently controlled to achieve constant linear speed winding at different roll diameters. It also enables quick replacement and positioning of the take-up and unwind roll 8. When the tape is being wound up, the length of the wound tape is accurately measured by the photoelectric sensor 6 and the crossbar 61. Through the above structure, when the tape in the winding mechanism reaches the set length, the winding automatically stops or a roll change operation is performed. When the tape is conveyed by the guide mechanism...Rotating the second shaft 71 causes the triangular pressure block 7 to press against the tape at the top of the conveyor belt 41 to control its tension. This structure allows for the detection and control of the tape tension during unwinding, ensuring stable tension and improving the stability of the slitting device. During unwinding and rewinding, an anti-slip sleeve prevents slippage of the tape roll. This structure reduces the decrease in cutting accuracy caused by slippage during unwinding and rewinding, improving the accuracy of the slitting device.
