[0023] The present invention provides an automatic tape winding and cutting device. To make the purpose, technical solution and effect of the present invention clearer and more definite, the following further describes the present invention in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the protection scope of the present invention.

[0024] Please refer to Figures 1 - 5The present invention provides an automatic tape winding and cutting device, comprising a mounting frame 1 with a side plate 1.1, a rotating drum 2 rotatably arranged on the side plate, a winding driving device 3 for driving the rotating drum to rotate, and a tape attaching and cutting device 4; the winding driving device 3 is connected to the rotating drum 2 through a transmission mechanism 5, and the tape attaching and cutting device 4 comprises a bracket 41, a tape roll fixing mechanism 9 arranged on the bracket, an attaching pressure roller 43, a cutting knife 44, a cutting driving cylinder 45 and a pressing mechanism 8 fixedly arranged on the rotating drum 2; the cutting knife 44 is used to cut the tape, the cutting driving cylinder 45 is used to drive the cutting knife 44 to press against the tape to achieve tape cutting, and the pressing mechanism 46 is used to drive the bracket 41 and the components on the bracket to approach the film roll, so that the attaching pressure roller and the tape wound on the attaching pressure roller are always closely attached to the film roll during the winding process.

[0025] In this embodiment, please refer to Figure 2 The cutting knife 44 includes a connecting block 44a connected to the end of the piston rod of the cutting drive cylinder, and a blade 44b connected to the connecting block with a screw; the cutting section of the blade 44b is serrated, and the cutting effect is good. The blade is a consumable part and can be replaced separately after being damaged.

[0026] Specifically, the bracket 41 includes a horizontal arm 41a and a vertical arm 41b vertically connected to each other, and a swing arm 41c swingably arranged on the vertical arm, and the horizontal arm 41a is fixedly connected to the clamping mechanism 46. Through such an arrangement, the structure of the bracket 41 is compact, which is convenient for disassembly, assembly and maintenance of the tape attaching and cutting device.

[0027] For further information, see Figure 2 ,and Figure 3 The vertical support arm is provided with a swing cylinder 47 for driving the swing arm to swing, the piston rod end of the swing cylinder is hinged to one end of the swing arm 41c, the tape roll fixing mechanism 9 is arranged at the other end of the swing arm 41c, and a fulcrum pressure roller 48 is arranged on the swing arm 41c, and the cutting knife 44 is located between the fulcrum pressure roller 48 and the attachment pressure roller 43. After the tape wrapping is completed, the swing cylinder 47 works to push the swing arm 41c to swing a certain angle, so that the attachment roller 43 maintains a certain distance from the film roll, and at the same time the fulcrum roller 48 presses the tape on the film roll A, thereby tightening the tape between the fulcrum roller 48 and the attachment roller 43, and the tape changes from a state tangent to the film roll to a warped state, reserving cutting space for the piston rod of the cutting drive cylinder 45 and the cutting knife 44, so that the cutting drive cylinder 45 can drive the cutting knife 44 to extend and cut the tape, thereby avoiding the cutting knife from damaging the film roll due to being too close to the surface of the film roll when cutting the tape.

[0028] In this embodiment, please refer to Figure 2A paper cover flattening mechanism 6 is provided between the tape roll fixing mechanism 9 and the attaching pressure roller 43. The paper cover flattening mechanism 6 comprises a flattening cylinder 61 fixedly provided on a swing arm and a paper cover pressing wheel 62 provided at the output end of the flattening cylinder. During the tape winding process, the paper cover pressing wheel 62 flattens the paper cover B in advance through the push of the flattening cylinder 61, so that the paper cover B and the film roll A are tightly pressed together, which plays a good positioning role for the paper cover B, facilitates the tape winding, and achieves a smooth and firm winding effect.

[0029] Preferably, see Figure 2 A transition roller 71, a tape anti-sticking roller 71, and a limit rod 73 for limiting the deviation of the tape unwinding are arranged between the tape roll fixing mechanism 9 and the attaching roller 43. The limit rod includes a fixed rod and two L-shaped limit arms symmetrically arranged on the fixed rod. The tape is wound around the transition roller, the tape anti-sticking roller, the two L-shaped limit arms in sequence, and then wound around the attaching roller. The tape anti-sticking roller mainly provides a guiding function for the tape to prevent the tape from interfering with the paper cover flattening mechanism. The two L-shaped limit arms can limit the unwinding position of the tape to prevent the tape from deviating from the attaching roller.

[0030] For details, please refer to Figure 1 The clamping mechanism 8 includes an L-shaped mounting seat 81 composed of a bottom plate 81a and a vertical plate 81b, a guide rail 82 arranged on the vertical plate and extending along the length direction of the vertical plate, a slider 83 slidably arranged on the guide rail, and a clamping cylinder 84 for driving the slider to slide along the guide direction of the guide rail. The horizontal arm 41a is fixedly arranged on the slider 83. The slider 83 is set in a shape that cannot be separated from the guide rail; the clamping cylinder 47 can push the bracket 41 and the components on the bracket toward the direction of the film roll according to the diameter of the film roll through the transmission of the guide rail 82 and the slider 83, so that the attachment roller 43 in the tape attachment and cutting device is always in close contact with the film roll A and the paper cover B, ensuring that the tape can effectively attach the film roll and the paper cover at the same time, achieving a good gluing effect, and improving the connection strength of the paper cover and the film roll.

[0031] Preferably, see Figure 1 The transmission mechanism 5 includes a driving gear 51 and a driven gear 52 meshing with each other. The driven gear 52 is coaxially arranged on the drum 2. The driving gear 51 is rotatably arranged on the side plate 1.1. The driving gear 51 is in transmission connection with the winding driving device 3. The pitch circle diameter of the driven gear is larger than the pitch circle diameter of the driving gear. That is, the driving device drives the drum to rotate through the transmission of the driving gear and the driven gear. Due to the high stability of the gear transmission, the drum can rotate smoothly.

[0032] Preferably, the winding driving device 3 is a reduction motor, and the output shaft of the reduction motor is in transmission connection with the driving gear. The reduction motor can provide a large torque, and can provide a high winding speed on the premise of ensuring stable transmission, thereby improving production efficiency.

[0033] Specifically, please refer to Figure 4 and Figure 5 The tape roll fixing mechanism 9 includes a support shaft 91 rotatably arranged on the swing arm, an outer sleeve 92 coaxially sleeved on the support shaft, a plurality of guide grooves 93 opened on the outer sleeve, a plurality of tensioning blocks 94 adaptively installed in each guide groove, and a tensioning driving mechanism for driving all the tensioning blocks to synchronously extend out of the guide grooves to clamp the tape cassette. The end surface of the tensioning block in contact with and tensioning the tape cassette is provided with tooth-shaped anti-slip lines. By providing the tooth-shaped anti-slip lines, the tape cassette can be prevented from slipping, and the tape cassette can be firmly clamped.

[0034] Further, one end of the outer sleeve 92 is a closed end 92.1, and the other end is an open end 92.2. The tensioning driving mechanism includes a sliding sleeve 95 slidably sleeved on the support shaft and a hand push disc 96 for pushing the sliding sleeve to move towards the closed end 92.1 of the outer sleeve 92. The sliding sleeve is connected to all the tensioning blocks 94 through a transmission link 97, and the hand push disc is tightly connected to the sliding sleeve.

[0035] The tape roll C includes an annular tape cassette and the tape pre-wound on the tape cassette. When tensioning and fixing the tape roll, first sleeved the inner ring of the tape cassette on the outer sleeve, and then press the hand push disc 96 hard to push the sliding sleeve 95 to slide relative to the support shaft 91 until the sliding sleeve 95 abuts against the closed end of the outer sleeve; at the same time, the sliding sleeve drives all the tensioning blocks to expand outwards through the transmission link to realize the tensioning and fixing of the tape cassette. The fixing method is simple and fast. When the tape of the tape roll is used up and needs to be replaced, it is necessary to use the traction reset mechanism 10 to pull the hand push disc, drive the sliding sleeve to move towards the opening direction of the outer sleeve, the tensioning blocks retract inwards to reset, and then exit the tensioned state, and the tape roll can be removed and replaced. The traction reset mechanism is not the inventive point of the present invention, so it will not be elaborated here.

[0036] In this embodiment, a film roll bracket for installing the film roll is horizontally and fixedly arranged on the side plate. The film roll bracket extends from the roller and ensures that the film roll installed on the film roll bracket is coaxially arranged with the roller. Of course, a bracket for supporting the film roll can also be independently provided.

[0037] The working principle is briefly described below: the tape roll C is clamped and fixed by the tape roll fixing mechanism 9. The tape is wound around the transition roller 71, the tape anti-sticking roller 72, the attachment roller 43, and the fulcrum roller 48 in sequence; when the tape is packaged, the clamping cylinder 84 in the clamping mechanism pushes the bracket and the components on the bracket toward the direction of the film roll according to the diameter of the film roll, so that the attachment roller 43 in the tape attachment and cutting device is always close to the film roll A and the paper cover B. At the same time, the paper cover pressure wheel 62 flattens the paper cover B under the action of the flattening cylinder 61, so that the paper cover B is completely attached to the film roll A, so as to facilitate the tape winding, and then the reduction motor 3 drives the drum 2 to rotate through the meshing transmission of the driving gear 51 and the driven gear 52, so that the tape attachment and cutting device 4 rotates around the film roll for several turns to realize the winding and packaging of the film roll A. The number of turns of tape winding is set according to the process requirements, generally 1 turn. After the tape wrapping is completed, the swing cylinder 47 works to push the swing arm 41c to swing a certain angle, so that the attachment roller 43 and the paper cover roller 61 maintain a certain distance from the film roll A, and at the same time the fulcrum roller 48 presses the tape on the film roll A, thereby tightening the tape between the fulcrum roller 48 and the attachment roller 43; at this time, the attachment roller 43 and the paper cover roller 62 are in an inclined state, and the tape changes from a state tangent to the film roll to a tilted state, so as to prepare a cutting space for the piston rod of the cutting drive cylinder and the cutting knife, so that the cutting drive cylinder can drive the cutting knife to extend and cut the tape; then the cutting drive cylinder 45 pushes the cutting knife 44 to cut the tape; finally, each cylinder is reset in reverse order. It can be seen that the automatic tape winding and cutting device provided by the present invention can automatically wrap and fix the tape on the film roll and the paper cover, and automatically cut the tape. Compared with the existing manual packaging, the packaging quality of each film roll is consistent, the tape is wound smoothly and firmly, the packaging efficiency is higher, and the use of labor is greatly reduced.

[0038] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all these changes or substitutions should fall within the protection scope of the present invention.
