[0038] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0039] The packaging tape winding machine of this embodiment is as follows Figures 1 to 18 As shown, it includes a frame 1, on which a conveying mechanism 4 for conveying a tube sleeve 2 to a tube sleeve opening 3 is provided, and the conveying mechanism includes an inclined passage 5 and a drop channel 6 connected to the inclined passage, the tube sleeve opening is connected to the drop channel, and two connecting rods 7 and 8 are provided on the tube sleeve opening, and the tube sleeve is placed on the inclined passage in sequence. Under the influence of gravity, the tube sleeve will roll down from the inclined passage to the drop channel by itself, and then roll down from the drop channel to the tube sleeve opening, and the two connecting rods on the tube sleeve opening just catch the tube sleeve. The first pushing mechanism 9 pushes the tube sleeve onto the tube sleeve clamping mechanism 10, and the first pushing mechanism is located on the frame and at the rear of the tube sleeve opening. The first pushing mechanism includes a support plate 11 fixed inside the frame, and a seventh cylinder 12 is provided on the support plate, and a circular push plate 13 is provided on the seventh cylinder, and the seventh cylinder pushes the circular push plate, and the circular push plate pushes the tube sleeve to the tube sleeve clamping mechanism. After the pushing is completed, the seventh cylinder pushes the circular push plate back, and a new tube sleeve rolls down to the tube sleeve opening again.

[0040] The sleeve clamping mechanism of this embodiment includes a first cylinder 14 arranged inside the frame, the first cylinder is hinged to a fixed plate 15, the fixed plate fixes a rotating shaft 16, the rotating shaft passes through the frame through a bearing and is connected to a swing arm 17, the rotating shaft passes through a support block 18 through a bearing, the support block is fixed to the frame, the first cylinder drives the rotating shaft to reciprocate, the rotating shaft drives the swing arm to reciprocate, and the swing arm is provided with a clamping assembly 19. The clamping assembly includes a base plate 20, the swing arm is connected to the base plate, and a wide finger cylinder 21 is provided on the base plate, and the wide finger cylinder drives the upper clamping mechanism 22 and the lower clamping mechanism 23 to open or clamp respectively, and the upper clamping mechanism or the lower clamping mechanism includes an arc block 24, and two clamping rods 25 and 26 are provided on the arc block. The clamping assembly also includes a left cylinder 27 and a right cylinder 28, which are respectively arranged on the left and right sides of the base plate. The left cylinder and the right cylinder are respectively provided with a conical rubber sleeve 29. When the first pushing mechanism pushes the tube sleeve onto the tube sleeve clamping mechanism, the left cylinder and the right cylinder block the tube sleeve to limit its pushing distance. In order to ensure the stability when the tube sleeve clamping mechanism clamps the tube sleeve to the position of the tube core sleeve opening 30, a balance bar 31 is hinged on the support block, and the balance bar is hinged with a connecting plate 32, and the connecting plate is fixed on the clamping assembly. The circular push plate pushes the tube sleeve along the two connecting rods to approach the clamping assembly. When it approaches to a suitable clamping distance, the left cylinder and the right cylinder push the conical rubber sleeve to block the tube sleeve to limit its pushing distance. After that, the left cylinder and the right cylinder retract the conical rubber sleeve, and the wide finger cylinder drives the upper clamping mechanism and the lower clamping mechanism to clamp the tube sleeve respectively. The first cylinder drives the rotating shaft to rotate, and the rotating shaft drives the swing arm to rotate, so that the sleeve clamping mechanism clamps the sleeve to a relative position between the sleeve core and the sleeve opening.

[0041] Next, the second pushing mechanism 33 pushes the barrel core sleeve mechanism 34 from the barrel core sleeve opening into the barrel sleeve. When the barrel core sleeve mechanism is pushed into the barrel sleeve, the left cylinder and the right cylinder block the barrel sleeve to limit its pushing distance. Then the wide finger cylinder drives the upper clamping mechanism and the lower clamping mechanism to open the barrel sleeve respectively. The first cylinder drives the rotating shaft to rotate, and the rotating shaft drives the swing arm to rotate, so as to realize the barrel sleeve clamping mechanism to retreat to the relative position of the barrel sleeve opening. The second pushing mechanism includes a support seat 35 arranged inside the frame, a third cylinder 36 and a slide bar 37 arranged on the support seat, and the third cylinder drives the slider to reciprocate on the slide bar. The slider is provided with a square plate 38, and the barrel core sleeve mechanism is provided on the square plate. The core sleeve mechanism includes a fourth motor 39, a first bearing seat 40, and a second bearing seat 41 arranged on a square plate, a main shaft 42 is arranged in the first bearing seat and the second bearing seat, the fourth motor is connected to a synchronous pulley 44 on the main shaft through a synchronous belt 43, the fourth motor drives the main shaft to rotate, and a tensioning mechanism 45 is arranged on the main shaft. The tensioning mechanism in the core sleeve mechanism will tighten the sleeve, specifically, the tensioning mechanism includes a first tensioning wheel 46 and a third tensioning wheel 47 fixed on the main shaft, and a second tensioning wheel 48 and a fourth tensioning wheel 49 movably arranged on the main shaft, the third tensioning wheel is provided with a fifth cylinder 50, and a connecting rod 51 on the second tensioning wheel passes through the third tensioning wheel and is connected to the fourth tensioning wheel. The first tension wheel has a first bevel 52, the second tension wheel has a second bevel, a first tension spring 53 is wound around the first and second bevels, the third tension wheel has a third bevel 54, the fourth tension wheel has a fourth bevel 55, and a second tension spring 56 is wound around the third and fourth bevels. The fifth cylinder drives the second tension wheel to be squeezed toward the first tension wheel, and the first tension spring between the second tension wheel and the first tension wheel is squeezed and convexly presses against the inner wall 57 of the sleeve. The second tension wheel pulls the fourth tension wheel to be squeezed toward the third tension wheel through the connecting rod, and the second tension spring between the third tension wheel and the fourth tension wheel is squeezed and convexly presses against the inner wall of the sleeve. The clamping mechanism 58 in the tensioning mechanism further presses the packaging belt into the tube sleeve. The clamping mechanism includes two sixth cylinders 60 and 61 fixed on the first tensioning wheel through a transverse plate 59. The sixth cylinder is connected to a connecting plate 62, and the connecting plate is connected to a pressing plate 63. When the tensioning mechanism tightens the tube sleeve, the pressing plate presses the packaging belt onto the tube sleeve.

[0042] The tension mechanism 98 of this embodiment conveys the packaging tape 64 to the packaging tape introduction mechanism 65, and the tension mechanism includes a tension frame 66 fixed on the frame, and the tension frame is provided with a first tape guide rod 67, a meter wheel 68 with an encoder, a reduction wheel mechanism 69, a second tape guide rod 70, and a proximity switch 71. A weight block 100 is provided on the pressing wheel, and the weight of the weight block acts on the pressing wheel, so that the pressing wheel 72 presses the packaging tape on the meter wheel, so that the meter wheel can accurately calculate the number of meters passed by the packaging tape through the number of rotations. The packaging tape passes through the first tape guide rod, the meter wheel, the reduction wheel, and the second tape guide rod in sequence. The reduction wheel mechanism includes a guide rod 73, a third spring 74 located on the guide rod, and a guide block 76 with a reduction wheel 75.

[0043] The packaging tape introduction mechanism of this embodiment conveys the packaging tape conveyed by the tension mechanism into the sleeve. Specifically, the packaging tape introduction mechanism includes a mounting seat 77 fixed in the frame, on which a sixth servo motor 78, a screw rod 79, and a push rod 80 are provided. The sixth servo motor drives the screw rod to rotate. When the screw rod rotates, a driving block 81 reciprocates on the screw rod. A push rod is fixed at the other end of the screw rod. The movement of the driving block drives the push rod to move. The push rod is hinged with the guide rail mechanism so that the guide rail mechanism is affected by gravity and leans on the guide rail rod. The push rod drives the guide rail mechanism 83 to reciprocate on the guide rail rod 99, which is fixed on the frame. The guide rail mechanism is provided with a guide wheel 84, a belt pressing cylinder 85, and a belt guide port 86. The packaging tape on the second guide rod passes through the guide wheel, the guide rail mechanism, and the guide port in turn. The packaging tape delivered from the guide port is pressed onto the cylinder sleeve by the pressing sheet. When the cylinder core sleeve mechanism rotates, the sixth servo motor drives the guide rail mechanism to reciprocate, and the packaging tape is wound around the cylinder sleeve in circles.

[0044] When the packaging tape is wound on the sleeve, the rotation speed of the sleeve core mechanism stops, while the packaging tape delivered by the tension mechanism is still at a normal conveying speed, which causes the packaging tape to be in a loose state during the tension mechanism stage. The tensioning mechanism in the sleeve core mechanism no longer tightens the sleeve, that is, the fifth cylinder drives the second tensioning wheel to move in the opposite direction of the first tensioning wheel, and the first tension spring between the second tensioning wheel and the first tensioning wheel is no longer squeezed. The second tensioning wheel moves the fourth tensioning wheel in the opposite direction of the third tensioning wheel through the connecting rod, and the second tensioning spring between the third tensioning wheel and the fourth tensioning wheel is no longer squeezed. Then the second pushing mechanism retracts the sleeve core mechanism into the sleeve core opening. Since the diameter of the sleeve core opening is smaller than the outer diameter of the wound packaging tape sleeve, the packaging tape sleeve will be blocked outside the sleeve core opening and the pressing sheet will be pulled away from the packaging tape and the sleeve due to the thrust. Under the influence of gravity, the packaging tape sleeve falls onto the receiving plate 87. The receiving plate and the baffle plate 82 are connected to the conveying mechanism 88. The bottom of the receiving plate is provided with an angle adjustment mechanism 89. The angle adjustment mechanism includes a vertical plate 90 arranged on the frame. The vertical plate is provided with a screw 91. When the screw is turned, the screw will lift the receiving plate, thereby achieving the purpose of adjusting the angle of the receiving plate. At the same time, the first cylinder drives the rotating shaft to rotate, and the rotating shaft drives the swing arm to rotate, so that the sleeve clamping mechanism clamps the sleeve again to the relative position of the sleeve opening of the core. At the same time, the clamped sleeve will further push the packaging tape sleeve to roll onto the conveying mechanism and be blocked by the baffle plate to prevent it from falling to the ground. The packaging tape will fall on the new sleeve. The second pushing mechanism pushes the sleeve mechanism from the sleeve opening into the sleeve again. At this time, the left cylinder and the right cylinder block the sleeve to limit its pushing distance. The tensioning mechanism tightens the sleeve, and the pressing sheet presses the packaging tape onto the sleeve. After that, the wide finger cylinder drives the upper clamping mechanism and the lower clamping mechanism to open the sleeve, the first cylinder drives the rotating shaft to rotate, and the rotating shaft drives the swing arm to rotate, so that the sleeve clamping mechanism returns to the relative position of the sleeve opening. At the same time, the fuse mechanism 92 cuts the packaging tape to separate the packaging tape sleeve. Thus, the next round of packaging tape is wound on the sleeve. When the core sleeve mechanism is started, a signal is sent to the belt pressing cylinder, so that the belt pressing cylinder presses the packaging tape lightly. After the packaging tape is subjected to the light pressure, the speed of the packaging tape passing through the packaging tape introduction mechanism will also slow down, so as to ensure that when the core sleeve mechanism rotates at a low speed, the section of the packaging tape between the packaging tape introduction mechanism and the core sleeve mechanism still has a reasonable tension, which ensures that the packaging tape is normally wound on the sleeve during the initial period. In order to further restore the reasonable tension of the packaging belt in the tension mechanism stage, the speed of the core sleeve mechanism will suddenly increase, that is, the speed of the core sleeve mechanism is faster than the packaging belt conveyed by the tension mechanism. Since the packaging belt suddenly changes from a loose state to a taut state, the packaging belt is affected by the tension and will pull the guide block to move up along the guide rod for buffering. In order to prevent the guide block from moving up and being damaged, the third spring on the guide rod will apply an elastic force to the guide block to relieve it.When the guide block moves up, the proximity switch at the bottom will feed back a signal to the tape pressing cylinder in the packaging tape introduction mechanism, thereby driving the tape pressing cylinder to stop applying pressure to the packaging tape. After the speed of the tube core sleeve mechanism returns to a reasonable speed, the guide block will move down and fall back to the bottom of the guide rod under the influence of gravity and face the proximity switch again. The above-mentioned fuse mechanism includes a tenth cylinder 93 arranged on the frame. The tenth cylinder drives the heated blade 94 to cut the packaging tape. The blade is an electric heating blade, that is, a heating wire is arranged inside the blade. The blade itself has a certain temperature, which makes it easier to cut the packaging tape. The conveying mechanism includes a conveyor belt 95 and a fourth motor 96. The fourth motor drives the conveyor belt to deliver the packaging tape tube sleeve to the packing box for packaging.

[0045] When the present invention is used, the operation of each mechanism is controlled by the control system 97. The strip packaging tape delivered by the front equipment (which is the prior art and will not be described repeatedly) is sequentially introduced into the first tape guide rod, the meter wheel, the reduction wheel, the second tape guide rod, the guide wheel, the guide rail mechanism, and the tape guide port. The conveying mechanism conveys the tube sleeve to the tube sleeve port, the first pushing mechanism pushes the tube sleeve onto the tube sleeve clamping mechanism, the tube sleeve clamping mechanism clamps the tube sleeve to the relative position of the tube core sleeve port, and the second pushing mechanism pushes the tube core sleeve mechanism from the tube core sleeve port into the tube sleeve. At this time, the packaging tape at the tape guide port is located on the tube sleeve, the tensioning mechanism tightens the tube sleeve, the pressing sheet presses the packaging tape onto the tube sleeve, and the tube sleeve clamping mechanism releases the clamping of the tube sleeve and retreats to the relative position of the tube sleeve port. The tube core sleeve mechanism rotates, and after the packaging tape is wound on the tube sleeve, the fusing mechanism cuts off the packaging tape, and the conveyor belt delivers the packaging tape tube sleeve to the packing box for packaging.

[0046] This embodiment has a high degree of automation, and the packaging tape is more stably wound onto the sleeve. In addition, this embodiment has a simpler structure and lower manufacturing cost.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
