Description

Technical Field

[0001] The invention relates to the technical field of adhesive tape auxiliary cutting, in particular to a slitting and cutting device for processing PET electronic adhesive tape. Background Art

[0002] PET electronic tape is a high-performance tape based on polyethylene terephthalate (PET) film. This tape plays an important role in the manufacturing and assembly of electronic products. PET material has excellent physical and chemical properties, including high strength, high temperature resistance, chemical corrosion resistance and good electrical insulation. These properties make PET electronic tape widely used in the electronics industry. Whether it is in the insulation and fixation of electronic components or in high temperature environments, PET electronic tape can effectively ensure the stability and reliability of electronic products. In the production process of PET electronic tape, winding is a key link. The production equipment is usually equipped with a winding device to wind the tape on a roller. After the tape reaches a certain thickness, a new roller needs to be sent to the winding position through a transmission device, and a cutter is used to cut the tape from between two rollers. However, this process still has some challenges; First, the cutting operation needs to be performed manually with a handheld cutter, which not only increases the labor intensity, but also easily causes errors during the cutting process. Secondly, the excess tape after cutting needs to be rewound a second time, which further increases the manpower and time costs. In addition, since the new roller to be rewound has a smaller adhesion part with the tape, the tape and the roller are prone to separation after cutting, affecting the subsequent rewinding operation.

[0003] Therefore, how to provide a slitting and cutting device for processing PET electronic tape is a problem that those skilled in the art urgently need to solve. Summary of the invention

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] refer to Figure 1-Figure 9 , including a slitting machine 1 and a slitting assembly 2, the slitting assembly 2 includes an executive electric cylinder 21 and a cutter 23, the executive electric cylinder 21 drives the cutter 23 to move up and down at the top of the inner side of the slitting machine 1 to press and cut the tape, a roller changing assembly 3 is arranged inside the slitting machine 1, the roller changing assembly 3 includes a first motor 31 and three groups of rollers 33, the surfaces of the three groups of rollers 33 are sleeved with winding rollers 34, the first motor 31 drives the three groups of rollers 33 to rotate inside the slitting machine 1, and a transmission mechanism 4 and a clutch mechanism 5 are respectively arranged on both sides of the slitting machine 1. The clutch mechanism 5 includes two groups of clutch rotating rods 53, one side of the single group of clutch rotating rods 53 is connected to the spline cylinder 42 on the output shaft of the second motor 41 through a spline rod 43, the second motor 41 drives the two groups of clutch rotating rods 53 to rotate in the same direction, and an anti-slip mechanism 7 is arranged between the two groups of clutch rotating rods 53; Two groups of clutch rotating rods 53 are movably arranged on both sides of the driving plate 52 through pressure sleeves, and the middle position of the driving plate 52 is fixed to the output end of the push-pull electric cylinder 51. The push-pull electric cylinder 51 drives the clutch rotating rod 53 to move horizontally through the driving plate 52. The contact ring 54 is fixed at one end of the clutch rotating rod 53. The clutch rotating rod 53 drives the contact ring 54 to contact the second contact groove 56 and the first contact groove 55 respectively. The first contact groove 55 is arranged on one side of the axis of the first swing seat 71, and the second contact groove 56 is arranged on the end surface of one side of the roller 33. The surfaces of the two groups of clutch rotating rods 53 are movably sleeved with a first swing seat 71 and a second swing seat 72, respectively. The tops of the first swing seat 71 and the second swing seat 72 are respectively fixedly connected with micro-electric push rods 73, which push the pressing roller 8 and the winding roller 34 to move closer and farther from each other. The second swing seat 72 and the clutch rotating rod 53 are connected by bottom bevel gears 45 and side bevel gears 46. The two groups of clutch rotating rods 53 rotate to drive the first swing seat 71 and the second swing seat 72 to swing in opposite directions. A knife seat assembly 6 is also provided between the first swing seat 71 and the second swing seat 72 on one side of the slitting machine 1. The first swing seat 71 and the second swing seat 72 swing towards each other to drive the knife seat frame 62 to rise inside the slitting machine 1. The knife seat frame 62 is located directly below the cutter 23.

[0029] After the first motor 31 is driven, the three groups of rollers 33 are driven to rotate. The surfaces of the three groups of rollers 33 are covered with winding rollers 34, so that after rotating 120 degrees, the new winding roller 34 will contact with the adhesive tape, and the winding roller 34 that has completed winding will be sent to one side by the rollers 33. Then, the execution electric cylinder 21 fixed on the top of the slitting machine 1 can drive the cutter 23 to descend inside the slitting machine 1 until it contacts with the surface of the adhesive tape. At the same time, the first swing seat 71 and the second swing seat 72 will swing in opposite directions, driving the knife holder 62 to rise under the adhesive tape until the cutter 23 and the knife holder 62 are in contact with each other, thereby realizing the cutting operation. In order to better achieve the cutting effect, the cutter 23 can be inclined to a certain extent to complete the automatic cutting operation. After cutting, the two groups of clutch rotating rods 53 are pulled by the push-pull electric cylinder 51 and move until they contact the ring 5 4 is separated from the second abutting groove 56 on one side of the roller 33, so that it is completely separated from the roller 33, and at the same time, the other side of the abutting ring 54 will be in contact with the first abutting groove 55 opened on one side of the first swing seat 71. At this time, the micro-electric push rod 73 on the top of the first swing seat 71 and the second swing seat 72 is driven to drive the pressing roller 8 to move toward the position of the tape on the surface of the winding roller 34, so that the pressing roller 8 and the tape surface are in contact. Then the second motor 41 is driven again, and its output shaft is fixed to the spline cylinder 42, so that the clutch rotating rod 53 can achieve the transmission effect while maintaining the extension and contraction between the spline rod 43 and the spline cylinder 42. In this way, the two sets of clutch rotating rods 53 are driven to rotate, and the first swing seat 71 and the second swing seat 72 will swing in opposite directions, so that the pressing roller 8 is driven to turn over on the tape on the surface of the winding roller 34, thereby increasing the contact area between the tape and the winding roller 34 and preventing the tape from separating from the winding roller 34. The rotation effect of the second swing seat 72 is controlled by the side bevel gear 46 and the bottom bevel gear 45, so that the rotation direction is opposite, so that the excess tape portion after cutting can be reeled up to a certain extent, and the push-pull electric cylinder 51 can then drive the contact ring 54 to fit and contact the second contact groove 56 on one side of the roller 33, so that under the control of the push-pull electric cylinder 51, the second motor 41 can respectively achieve two transmission effects: First, the two clutch rotating rods 53 are driven to rotate in the same direction to realize the rewinding and at the same time complete the secondary rewinding of the excess tape portion; Secondly, the first swing seat 71 and the second swing seat 72 are driven to rotate in opposite directions, so that the laminating roller 8 can increase the contact area between the adhesive tape and the surface of the winding roller 34 to prevent the occurrence of separation.

[0030] refer to Figure 8 The number of the side bevel teeth 46 is two groups, and the two groups of side bevel teeth 46 are respectively vertically meshed on both sides of the bottom bevel teeth 45. The bottom bevel teeth 45 are movably arranged above the electromagnetic push rod through the bearing, and the electromagnetic push rod drives the bottom bevel teeth 45 to move up and down inside the slitting machine 1. The surfaces of the two groups of clutch rotating rods 53 are fixed with pulleys 44, and the two groups of pulleys 44 are connected and driven by a transmission belt 47. The two groups of side bevel teeth 46 are respectively fixed on one side of the axis of the second swing seat 72 and one side of the pulley 44, and the clutch rotating rod 53, the side bevel teeth 46 and the second swing seat 72 are coaxial.

[0031] In this embodiment, the movement of the clutch rotating rod 53 will pull the contact ring 54 to fit into the first contact groove 55. During this process, the side bevel teeth 46 will also be driven by the pulley 44 to move, so that the two groups of side bevel teeth 46 move away from each other until the contact ring 54 fits tightly into the first contact groove 55. At this time, the bottom bevel teeth 45 can rise under the action of the electromagnetic push rod to achieve the docking and meshing operation with the two groups of side bevel teeth 46 below. At this time, the rotation effect of the clutch rotating rod 53 can drive the second swing seat 72 to swing in the opposite direction through the meshing effect of the side bevel teeth 46 and the bottom bevel teeth 45, thereby driving the excess part of the tape to be wound with the surface of the winding roller 34. The swing of the first swing seat 71 on the other side increases the contact area between the tape and the surface of the winding roller 34.

[0032] refer to Figure 2 , Figure 5 , Figure 6 and Figure 7 The surfaces of the first swing seat 71 and the second swing seat 72 are both provided with a limiting slide groove 74, a slider is provided at the output end of the micro electric push rod 73 near the limiting slide groove 74, the pressing roller 8 is fixed to the slider through a connecting rod, and an arc support seat is provided at the position of the slitting machine 1 near the first swing seat 71 and the second swing seat 72, and the first swing seat 71 and the second swing seat 72 are limitedly set on the support seat.

[0033] In this embodiment, the laminating roller 8 can drive the slider to slide to a certain position inside the limiting slide groove 74, thereby driving the laminating roller 8 to closely contact the tape on the surface of the winding roller 34 with different winding thicknesses, and after the laminating roller 8 is pulled away from the winding roller 34, the rotation effect of the roller 33 can be carried out normally, preventing the laminating roller 8 from hindering the rotation of the roller 33; The first swing seat 71 and the second swing seat 72 are supported by the arc support seat on the surface of the slitting machine 1 to complete the limiting operation, making the stability stronger, and damping rubber and other components can be further provided between the arc support seat and the first swing seat 71 and the second swing seat 72 to achieve limiting operation to prevent the first swing seat 71 from flipping over under the action of its own gravity after the contact ring 54 is separated from the first contact groove 55. This is the limiting operation in the prior art, so it will not be described again.

[0034] refer to Figure 7 The spline rod 43 is limitedly telescopic inside the spline cylinder 42, the spline cylinder 42 is fixed to the output end of the second motor 41, and the second motor 41 is fixed to the side of the slitting machine 1 through a bracket.

[0035] In this embodiment, the telescopic transmission effect between the spline cylinder 42 and the spline rod 43 satisfies the second motor 41 driving the two sets of clutch rotating rods 53 to rotate while achieving the lateral displacement effect of the clutch rotating rod 53 itself.

[0036] refer to Figure 3 The first motor 31 is fixed on the side of the slitting machine 1. The output end of the first motor 31 is meshed with the lower part of the transmission gear 35 through a single tooth. One side of the transmission gear 35 is fixed to the support frame 32 through a connecting rod. One side of the three groups of rollers 33 are rotatably arranged on the support frame 32 through shaft sleeves. The angle between two adjacent groups of rollers 33 about the axis of the support frame 32 is 120 degrees.

[0037] In this embodiment, after being driven, the first motor 31 can directly drive the support frame 32 to rotate through the meshing effect with the transmission teeth 35, and the three groups of rollers 33 rotate on the support frame 32, so that when the support frame 32 itself rotates, it drives the rollers 33 to flip over, thereby driving the winding roller 34 to rotate and displace, so that the new winding roller 34 fits the tape to meet the repeated winding and cutting operations. In addition, the setting of the three groups of rollers 33 enables when two groups of rollers 33 are realizing the winding and docking work, the other group of rollers 33 can realize loading and unloading operations, which effectively improves production efficiency.

[0038] refer to Figure 2 and Figure 5The knife seat assembly 6 includes a sliding rod 61 and two groups of pushing rods 63. The two groups of pushing rods 63 are movably connected to each other through axle pins. One side of the two groups of pushing rods 63 is movably arranged on the surface of the first swing seat 71 and the second swing seat 72 through side ear plates. The top of the sliding rod 61 is movably connected to the two groups of pushing rods 63. One side of the sliding rod 61 is slidably connected to the inner surface of the slitting machine 1 through a limiting slider, and the knife seat frame 62 is fixed to one side of the bottom of the sliding rod 61.

[0039] In this embodiment, since the first swing seat 71 and the second swing seat 72 will drive the two sets of pushing rods 63 to squeeze each other during the flipping process, the movable connection positions of the two sets of pushing rods 63 will pull the sliding rod 61 to slide and rise on the surface of the slitting machine 1. At this time, the pressing roller 8 will first tighten the surface of the tape until the knife holder 62 and the cutter 23 are in contact with each other to achieve cutting, thereby improving the cutting stability. After the cutting is completed, the continuous swinging of the first swing seat 71 and the second swing seat 72 will complete the above fitting operation.

[0040] refer to Figure 2 The top of the cutter 23 is elastically connected to the connecting plate 22 through a spring rod 24, and the center position of the connecting plate 22 is fixed to the output end of the actuator cylinder 21.

[0041] In this embodiment, during the continuous flipping of the first swing seat 71 and the second swing seat 72, a continuous upward force will be provided to the knife holder 62, which will squeeze the spring rod 24, so that the connecting plate 22 and the cutter 23 are close to each other, preventing the cutter 23 from conflicting with the knife holder 62, resulting in the first swing seat 71 and the second swing seat 72 being restricted and unable to swing.

[0042] Working principle: First, the push-pull electric cylinder 51 is driven to pull the clutch rotating rods 53 on both sides to move through the driving plate 52, and the contact ring 54 on one side of the clutch rotating rod 53 will be pulled into the first contact groove 55 on the side of the first swing seat 71 and contact. At this time, the clutch rotating rod 53 and the first swing seat 71 can be regarded as a whole, and then the bottom bevel tooth 45 is pushed up by the electromagnetic push rod, and its two sides are respectively connected and meshed with the second swing seat 72 and the side bevel teeth 46 on the side of the pulley 44. At this time, the second motor 41 in the transmission mechanism 4 drives the spline cylinder 42 to rotate. The spline cylinder 42 can be telescopically slid between the spline rod 43, so that the movement effect of the clutch rotating rod 53 above is met. In this way, a single set of clutch rotating rods 53 is driven to rotate, and the two sets of clutch rotating rods 53 are engaged. The transmission connection is achieved through the pulley 44 and the transmission belt 47, so that the two sets of clutch levers 53 will rotate in the same direction at this time, and under the meshing of the side bevel teeth 46 and the bottom bevel teeth 45, the first swing seat 71 and the second swing seat 72 will swing in opposite directions. Before the swing, the micro-electric push rod 73 on the top of the first swing seat 71 and the second swing seat 72 can drive the slider to move downward inside the limiting slide groove 74, so that the pressing roller 8 and the tape on the surface of the winding roller 34 are in contact. During the swinging process, the pressing roller 8 will rotate on the tape on the surface of the winding roller 34 with the roller 33 as the center, so that the tape is tensioned. In this process, since the first swing seat 71 and the second swing seat 72 swing in opposite directions, the pushing rod 63 in the knife seat assembly 6 will be pushed to swing , the pushing rod 63 drives the sliding rod 61 to move upward on one side of the slitting machine 1, and the knife holder 62 rises at the bottom of the tape at this time. At the same time, the actuator electric cylinder 21 in the slitting component 2 is driven, and under the connection of the connecting plate 22, the cutter 23 is driven to fit with the knife holder 62 above the tape to complete the cutting. Then the first swing seat 71 and the second swing seat 72 continue to swing, and the pressing roller 8 on one side of the second swing seat 72 will drive the tape to fit well with the surface of the winding roller 34 to prevent the tape from separating from the winding roller 34. The pressing roller 8 on one side of the first swing seat 71 assists in the winding operation between the tape and the winding roller 34. At the same time, the friction effect between the knife holder 62 and the cutter 23 will drive the spring rod 24 to achieve elastic deformation, preventing the first swing seat 71 and the second swing seat 7 2 is restricted. After the cutting is completed, the first swing seat 71, the second swing seat 72 and the slitting assembly 2 are reset. The bottom cone gear 45 descends under the action of the electromagnetic push rod. Then the push-pull electric cylinder 51 drives the two sets of clutch rotating rods 53 to move through the driving plate 52, so that the contact ring 54 and the second contact groove 56 on one side of the roller 33 are tightly connected. At this time, the driving effect of the second motor 41 will drive the two sets of clutch rotating rods 53 to rotate, and then drive the two sets of rollers 33 to rotate in the same direction to achieve a better winding operation. Finally, the push-pull electric cylinder 51 drives the contact ring 54 to disengage from the roller 33. The first motor 31 drives the rotating frame 32 to rotate directly through the transmission effect of the transmission tooth 35. The winding roller 34 that has been wound on the surface of the roller 33 will be brought to the bottom to realize the unloading operation.The new winding roller 34 is brought to the winding position for the next winding.
