Description

Technical Field

[0001] This invention relates to the field of electromagnetic components technology, specifically to an insulating paper rolling machine and its usage method. Background Technology

[0002] In the manufacture of electromagnetic components such as transformers and inductors, insulating paper is used to isolate the layers or windings from the magnetic core to prevent breakdown.

[0003] Traditional methods involve first punching and cutting the insulating paper into strips, then winding it together with the copper wire. This process is inefficient, results in uneven tension, and causes wrinkling. Another method involves clamping the magnetic core onto a rotating spindle, with the paper strip wound around the core after passing through guide rollers and pressure rollers. While this method offers good continuity, the core needs to be repeatedly loaded and unloaded. The rotation speed is limited by the core's mass, and centrifugal force at high speeds causes vibration, resulting in inconsistent winding tightness. Furthermore, the core's sharp edges can easily cut the paper. Summary of the Invention

[0004] The purpose of this application is to provide an insulating paper roll machine and its usage method, which overcomes the problems of low production efficiency, uneven tension, easy wrinkling, and inconsistent winding tightness of insulating paper rolls in the prior art by pre-producing insulating paper rolls.

[0005] The present invention provides an insulating paper rolling machine, the technical solution of which is: an insulating paper rolling machine, including a machine body, a paper rolling seat, a paper feeding mechanism, a paper feeding mechanism, a paper rolling mechanism, an adhesive tape applicator and a transfer mechanism;

[0006] The paper roll holder can be lifted and lowered on the machine body, and the top surface of the paper roll holder is provided with a paper roll groove.

[0007] The paper feeding mechanism is used to supply insulating paper strips of a preset length;

[0008] The paper feeding mechanism is used to transport the insulating paper strip of a preset length provided by the paper supply mechanism to the top of the paper roll holder;

[0009] The paper winding mechanism is used to roll the insulating paper strip into an insulating paper roll. It includes a paper pressing assembly located above the paper winding seat and two limiting assemblies symmetrically located on both sides of the paper winding seat. The paper winding seat and the paper pressing assembly can move relative to each other. The paper winding seat and the paper pressing assembly cooperate to press the middle part of the insulating paper strip that is conveyed by the paper feeding mechanism to the paper winding seat into the paper winding groove, so that the two ends of the insulating paper strip form free ends that are raised upwards.

[0010] The two limiting components are provided with arc-shaped guide surfaces on opposite sides for synchronously squeezing the two free ends to make them curl along the arc-shaped guide surfaces, causing the entire insulating paper strip to be passively curled into a cylindrical insulating paper roll, and making the ends of the two free ends relatively parallel, and forming a tape mounting gap between the two limiting components, with the two free ends located within the tape mounting gap.

[0011] The tape applicator is located on the side of the paper roll holder away from the paper feeding mechanism. It is used to attach the tape strip to the top of the two free ends of the insulating paper roll within the tape applicator gap. The length direction of the tape strip is perpendicular to the length direction of the insulating paper strip, and both ends of the tape strip are located outside the insulating paper roll.

[0012] The transfer mechanism is used to bend and attach the two ends of the tape strip to the bottom of the two free ends, and to transfer and unload the insulating paper roll.

[0013] Optionally, the paper pressing assembly includes a vertical plate vertically mounted on the machine body, a mounting plate movably mounted on the vertical plate, a paper pressing head located at the end of the mounting plate away from the vertical plate, and a paper pressing cylinder for driving the mounting plate to move. The mounting plate is arranged along the length direction perpendicular to the vertical plate, the paper pressing head is used to cooperate with the paper roll holder, and the paper pressing cylinder is fixedly mounted on the vertical plate for driving the mounting plate to move along the Y-axis in a direction closer to or away from the paper roll holder.

[0014] When the paper-pressing cylinder drives the mounting plate to move along the Y-axis direction, causing the paper-pressing head to move directly above the paper roll holder, the paper feeding mechanism delivers the insulating paper strip to the bottom side of the paper-pressing head or between the paper roll holder and the paper-pressing head. The paper roll holder rises and abuts against the bottom of the paper-pressing head, so that both ends of the insulating paper strip form upward-curving free ends.

[0015] Optionally, both limiting components include a base fixed on the machine body, a limiting cylinder on the base, and a limiting seat on the power rod of the limiting cylinder. The two bases are symmetrically arranged on both sides of the paper roll holder, and the two arc-shaped guide surfaces are respectively located on opposite sides of the two limiting seats. The two limiting cylinders drive the two limiting seats to move synchronously closer to the paper roll holder, and guide the insulating paper strip to curl by squeezing the two free ends, thus forming the tape mounting gap.

[0016] Optionally, the tape applicator includes a tape supply unit, a tape gripping unit, a tape cutting unit, and a tape applicator. The tape supply unit supplies tape, the tape gripping unit grips one end of the tape and pulls it out to a preset length, the tape cutting unit cuts the continuous tape into tape strips of a preset length, and the tape applicator attaches the tape strips to the tops of the two free ends within the tape applicator gap.

[0017] Optionally, the paper pressing assembly further includes a vertical groove on the paper pressing head, a pad block that can be raised and lowered in the vertical groove, and a pad block cylinder for driving the pad block to rise and fall vertically relative to the vertical groove. The pad block is used to support the top of the inner circumference of the insulating paper roll when the tape strip is applied in the tape application unit, and the supporting position corresponds to the ends of the two free ends.

[0018] Optionally, the machine body is provided with a feeding channel, and the transfer mechanism includes a fixed frame fixed on the machine body, a lifting seat that can be raised and lowered on the fixed frame, a rotating frame that is rotatably disposed on the bottom side of the lifting seat, a gripper seat fixed on the bottom side of the rotating frame, a first transfer gripper and a second transfer gripper that are slidably disposed on the gripper seat, and a transfer gripper cylinder for driving the first transfer gripper and the second transfer gripper to move toward each other or away from each other.

[0019] The rotating frame can rotate back and forth between the paper roll holder and the feeding channel. The first transfer gripper and the second transfer gripper cooperate to bend and attach the two ends of the tape strip attached to the top of the outer ring of the insulating paper roll to the bottom of the two free ends.

[0020] Optionally, the paper feeding mechanism includes a paper feeding unit, a paper clamping unit, and a paper cutting unit. The paper feeding unit is used to supply insulating paper, the paper clamping unit is used to clamp the end of the insulating paper and pull the insulating paper out to a preset length, and the paper cutting unit is used to cut the insulating paper into insulating paper strips of a preset length.

[0021] Optionally, the paper feeding mechanism includes a sliding seat movably mounted on the machine body, a movable seat slidably mounted on the sliding seat, a fixed seat fixedly mounted on the movable seat, a first feeding gripper and a second feeding gripper mounted on the fixed seat, an X-axis moving module for driving the sliding seat to move relative to the machine body along the X-axis direction, a Y-axis cylinder for driving the movable seat to move relative to the sliding seat along the Y-axis direction, and a feeding gripper cylinder for driving the first feeding gripper and the second feeding gripper to open and close.

[0022] Optionally, the tape application unit includes a tape application bracket fixedly mounted on a sliding seat, a tape application base vertically mounted on the tape application bracket, a Z-axis cylinder for driving the tape application base to move relative to the tape application bracket along the Z-axis direction, and an adsorption head mounted on the tape application base. The tape application bracket is located on one side of the sliding seat, the Z-axis cylinder is used to drive the tape application bracket to move up and down along the Z-axis, and the adsorption head is connected to a vacuum adsorption device so that the adsorption head can pick up and release the tape strip.

[0023] When the X-axis moving module drives the sliding seat to move to the first position, the moving seat is located at the paper feeding mechanism, and the tape applicator moves synchronously above the paper roll holder and performs tape applicator operation through the suction head.

[0024] When the X-axis moving module drives the sliding seat to the second position, the moving seat is located at the paper roll seat, and the tape mounting bracket moves synchronously to the tape supply unit.

[0025] This application also provides a method of using an insulating paper rolling machine, applicable to the insulating paper rolling machine described above, comprising the following steps:

[0026] The paper feeding mechanism provides insulating paper strips of a preset length;

[0027] The paper feeding mechanism delivers a pre-set length of insulating paper strip to the space between the paper roll holder and the paper pressing assembly, driving the paper roll holder to rise relative to the machine body. The paper roll holder and the paper pressing assembly cooperate to press the middle part of the insulating paper strip into the paper roll groove on the paper roll holder, so that both ends of the insulating paper strip form free ends that curve upwards.

[0028] By simultaneously squeezing the two free ends of the insulating paper strip with two limiting components, the entire insulating paper strip is guided to curl into an insulating paper roll and the two free ends are relatively parallel. At this time, the two limiting components simultaneously form the tape mounting gap, and the ends of the two free ends are both located within the tape mounting gap.

[0029] The tape strip is attached to the top of the two free ends within the tape application gap using a tape application mechanism.

[0030] The two ends of the tape strip are attached to the bottom of the two free ends by the transfer mechanism, and then the insulating paper roll is transferred and unloaded.

[0031] After adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0032] This application provides an insulating paper rolling machine and its usage method. During operation, an insulating paper strip of a preset length provided by a paper feeding mechanism is conveyed to a paper rolling seat by a paper feeding mechanism. The paper pressing component of the paper rolling mechanism and the paper rolling seat cooperate to press the middle part of the insulating paper strip into the paper rolling groove, so that the two ends of the insulating paper strip form upward-curving free ends. The two free ends are simultaneously squeezed by a limiting component, causing the two free ends to curl along the arc-shaped guide surface, which causes the insulating paper strip to be passively curled into a cylindrical insulating paper roll, and the ends of the two free ends are relatively parallel. Then, an adhesive tape is attached to the top of the two free ends by an adhesive tape attaching mechanism. Finally, the two ends of the adhesive tape are bent and attached to the bottom of the two free ends by a transfer mechanism, and the insulating paper roll is transferred and unloaded, thus completing the preparation of the insulating paper roll. Compared with the existing technology of winding insulating paper strips around the outer periphery of the magnetic core, this application overcomes the problems of low production efficiency, uneven tension, easy wrinkling and inconsistent winding tightness in the winding of insulating paper by prefabricating insulating paper rolls that meet the requirements, thereby improving the preparation efficiency and quality of insulating paper rolls.

Detailed Implementation

[0050] The following will refer to the appendices in the embodiments of the present invention. Figures 1-15 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0051] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0052] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, if the word "and / or" appears throughout the text, it means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0053] This embodiment provides an insulating paper rolling machine, as shown in the following figure. Figures 1-15 The system includes a body 10, a paper roll holder 20, a paper feeding mechanism 30, a paper delivery mechanism 40, a paper winding mechanism 50, an adhesive tape applicator 60, and a transfer mechanism 70. The paper roll holder 20 is vertically mounted on the body 10. The body 10 is equipped with a lifting cylinder 22 for driving the paper roll holder 20 to move vertically relative to the body 10. A paper winding groove 21 is formed on the top surface of the paper roll holder 20. The paper feeding mechanism 30 supplies insulating paper strips 200 of a preset length. The paper delivery mechanism 40 transports the insulating paper strips 200 of the preset length provided by the paper feeding mechanism 30 to the top of the paper roll holder 20. The paper winding mechanism 50 curls the insulating paper strips 200 to form an insulating paper roll 300. Specifically, the paper winding mechanism 50 includes a paper pressing assembly 51 located above the paper roll holder 20 and two limiting assemblies 52 symmetrically located on both sides of the paper roll holder 20. The paper roll holder 20 moves relative to the machine body 10 toward the paper pressing assembly 51 and cooperates with the paper pressing assembly 51 to press the middle part of the insulating paper strip 200 above the paper roll holder 20, which is fed by the paper feeding mechanism 40, into the paper roll groove 21, and to form upward-curving free ends 201 at both ends of the insulating paper strip 200.

[0054] Both limiting components 52 have arc-shaped guide surfaces 521 on opposite sides, which are used to synchronously squeeze the two free ends 201 of the insulating paper strip 200 so that the two free ends 201 are rolled along the arc-shaped guide surfaces 521, causing the entire insulating paper strip 200 to be passively rolled into an insulating paper roll 300, and making the ends of the two free ends 201 relatively parallel, and forming a tape mounting gap between the two limiting components 52, with both free ends 201 located within the tape mounting gap.

[0055] The tape applicator 60 is located on the side of the paper roll holder 20 opposite to the paper feeding mechanism 30. It provides a tape strip 400 of a preset length and applies the tape strip 400 to the tops of the two free ends 201 within the tape applicator gap. The length direction of the tape strip 400 is perpendicular to the length direction of the insulating paper strip 200, and both ends of the tape strip 400 are located outside the insulating paper roll 300. It should be noted that in this embodiment, the insulating paper strip 200 is arranged along the X-axis (i.e., the length direction of the body 10), and the tape strip 400 is arranged along the Y-axis (i.e., the width direction of the body 10). The width of the tape strip 400 is smaller than the tape applicator gap, so that the tape strip 400 can smoothly pass through the tape applicator gap and be attached to the tops of the two free ends 201.

[0056] In this embodiment, when the two limiting components 52 simultaneously compress the two free ends 201 of the insulating paper strip 200, the two free ends 201 are relatively parallel and have a certain gap. The width of the adhesive tape 400 is greater than this gap. When the adhesive tape 400 is attached to the top of the two free ends 201, both sides of the adhesive tape 400 are respectively attached to the ends of the two free ends 201, thereby fixing the two free ends 201 and preventing the two free ends 201 from shifting and affecting the forming quality of the insulating paper roll 300. In other embodiments, the ends of the two free ends 201 of the insulating paper strip 200 may also be in the form of being attached vertically or abutting against each other, which is not limited here.

[0057] The transfer mechanism 70 is used to bend and attach the two ends of the tape strip 400 to the bottom of the two free ends 201, and to transfer and unload the insulating paper roll 300.

[0058] During operation, the paper feeding mechanism 30 provides an insulating paper strip 200 of a preset length. The paper feeding mechanism 40 transports the insulating paper strip 200 to the top of the paper roll holder 20. At this time, the paper roll holder 20 is driven to rise relative to the machine body 10 and cooperate with the paper pressing assembly 51 to press the middle part of the insulating paper strip 200 into the paper roll groove 21, so that the two ends of the insulating paper strip 200 form upward-curving free ends 201. Then, the limiting assembly 52 simultaneously squeezes the two free ends 201 to make them curl along the arc-shaped guide surface 521, so that the entire insulating paper strip 200 is passively curled to form a cylindrical insulating paper roll 300. Then, the tape attaching mechanism 60 attaches the tape strip 400 to the top of the two free ends 201 in the tape attaching gap. Finally, the transfer mechanism 70 bends and attaches the two ends of the tape strip 400 to the bottom of the two free ends 201, completing the preparation of the entire insulating paper roll 300, and then the insulating paper roll 300 is transferred and unloaded. Compared to the traditional method of winding the insulating paper roll 300 onto the magnetic core, the insulating paper roll 300 is prepared by the insulating paper rolling machine provided in this application, which effectively avoids problems such as low rolling efficiency, easy wrinkling, and inconsistent winding tightness.

[0059] Furthermore, the paper feeding mechanism 30 includes a paper feeding unit 31, a paper clamping unit 32, and a paper cutting unit 33. The paper feeding unit 31 is used to supply continuous insulating paper, the paper clamping unit 32 is used to clamp the end of the insulating paper and pull the insulating paper out to a preset length, and the paper cutting unit 33 is used to cut the continuous insulating paper, thereby cutting the insulating paper into insulating paper strips 200 of a preset length.

[0060] In some specific embodiments, the paper feeding unit 31 includes a paper feeding bracket 311 fixedly mounted on the machine body 10, a paper winding wheel 312 rotatably mounted on the paper feeding bracket 311, and insulating paper wound on the paper winding wheel 312; the paper clamping unit 32 includes a paper clamping fixing plate 321 fixedly mounted on the machine body 10, a paper clamping claw 322 slidably mounted on the paper clamping fixing plate 321, and a third [unclear] for driving the paper clamping claw 322 to move relative to the paper clamping fixing plate 321 toward or away from the paper feeding bracket 311. The paper-clamping cylinder 323 and the second paper-clamping cylinder 324 for driving the paper-clamping jaws 322 to open and close; the paper-cutting unit 33 includes a first paper-cutting cylinder fixed on the paper-feeding bracket 311, a paper-cutting blade 331 on the power rod of the paper-cutting cylinder, and a second paper-cutting cylinder for driving the paper-cutting blade 331 to open and close, wherein the first paper-cutting cylinder is used to drive the paper-cutting blade 331 to move toward or away from the insulating paper, so that the paper-cutting blade 331 can cut the insulating paper pulled out by the paper-clamping jaws 322.

[0061] During paper feeding, the second paper-clamping cylinder 324 drives the paper-clamping jaws 322 to close, clamping the free end 201 of the insulating paper. The first paper-clamping cylinder 323 drives the paper-clamping jaws 322 to move away from the paper feeding bracket 311, pulling the insulating paper wound on the winding wheel to a preset length. At this time, the first paper-cutting cylinder drives the paper-cutting blade 331 to move closer to the insulating paper. Subsequently, the second paper-cutting cylinder drives the paper-cutting blade 331 to close, cutting the insulating paper to obtain an insulating paper strip 200 of a preset length. Simultaneously, by adjusting the stroke of the first paper-clamping cylinder 323, the length of the insulating paper strip 200 can be adjusted, allowing for the cutting of insulating paper strips 200 of different lengths to meet production needs.

[0062] Furthermore, the paper feeding mechanism 40 includes a sliding seat 41 movably disposed on the machine body 10, a movable seat 42 slidably disposed on the sliding seat 41, a fixed seat 43 fixedly disposed on the movable seat 42, a first feeding gripper 44 and a second feeding gripper 45 disposed on the fixed seat 43, an X-axis moving module 46 for driving the sliding seat 41 to move relative to the machine body 10 in the X-axis direction, a Y-axis cylinder 47 for driving the movable seat 42 to move relative to the sliding seat 41 in the Y-axis direction, and a gripper cylinder 48 for driving the first feeding gripper 44 and the second feeding gripper 45 to open and close.

[0063] The X-axis direction is the length direction of the machine body 10, and the Y-axis direction is the width direction of the machine body 10. The sliding seat 41 is driven to move along the X-axis direction by the X-axis moving module 46, so that the moving seat 42 can move back and forth between the paper feeding mechanism 30 and the paper roll holder 20. When the X-axis moving module 46 drives the sliding seat 41 to the first position, the moving seat 42 is located at the paper feeding mechanism 30. The Y-axis cylinder 47 drives the moving seat 42 to move relative to the sliding seat 41 along the Y-axis direction, so that the moving seat 42 is close to the paper feeding mechanism 30. Then, the gripper cylinder 48 drives the first feeding gripper 44 and the second feeding gripper 45 to close, thereby gripping the insulating paper strip 200 of the preset length provided by the paper feeding mechanism 30. At this time, the Y-axis cylinder 47 drives the moving seat 42 to move away from the paper feeding mechanism 30, so that the moving seat 42 is reset. The X-axis moving module 46 drives the sliding seat 41 to the second position, driving the moving seat 42 to move to the paper roll holder 20. At this time, the Y-axis cylinder 47 drives the moving seat 42 to move towards the paper roll holder 20, thereby conveying the insulating paper strip 200 of the preset length to the top of the paper roll holder 20.

[0064] Furthermore, the paper pressing assembly 51 includes a vertical plate 511 vertically mounted on the machine body 10, a mounting plate 512 movably mounted on the vertical plate 511, a paper pressing head 513 located at one end of the mounting plate 512 away from the vertical plate 511, and a paper pressing cylinder 514 for driving the mounting plate 512 to move. The mounting plate 512 is arranged along the length direction perpendicular to the vertical plate 511 and can move in the Y-axis direction toward or away from the paper roll holder 20. The paper pressing head 513 is used to cooperate with the paper roll holder 20. The paper pressing cylinder 514 is fixedly mounted on the vertical plate 511, and its power rod is connected to one end of the mounting plate 512 away from the paper roll holder 20, for driving the mounting plate 512 to move in the Y-axis direction toward or away from the paper roll holder 20.

[0065] When the paper pressing cylinder 514 drives the mounting plate 512 to move along the Y-axis, causing the paper pressing head 513 to move directly above the paper roll holder 20, the paper feeding mechanism 40 conveys the insulating paper strip 200 to the bottom side of the paper pressing head 513 or between the paper roll holder 20 and the paper pressing head 513. At this time, the paper roll holder 20 is driven to rise relative to the machine body 10, causing the paper roll holder 20 to lift the insulating paper strip 200 to the bottom of the paper pressing head 513 and deform the insulating paper strip 200. Due to the setting of the paper roll groove 21 on the paper roll holder 20, the middle part of the insulating paper strip 200 is pressed into the paper roll groove 21, and at the same time, the two ends of the insulating paper strip 200 form upward-curving free ends 201. It should be noted that when the paper roll holder 20 contacts the insulating paper strip 200, the first and second paper feeding jaws of the paper feeding mechanism 40 simultaneously release the insulating paper strip 200. At the same time, the Y-axis cylinder 47 drives the moving seat 42 to move away from the paper roll holder 20 to make way for the paper roll mechanism 50 and ensure the normal operation of the paper roll mechanism 50. At this time, the paper feeding mechanism 40 has completed one paper feeding and can be driven by the X-axis moving module 46 to move the moving seat 42 to the paper feeding mechanism 30 for the next paper feeding operation.

[0066] Furthermore, each of the two limiting components 52 includes a base 522 fixed on the machine body 10, a limiting cylinder 523 on the base 522, and a limiting seat 524 on the power rod of the limiting cylinder 523. The two bases 522 are symmetrically arranged on both sides of the paper roll holder 20. The two arc-shaped guide surfaces 521 are respectively located on the opposite side of the two limiting seats 524. The two limiting cylinders 523 drive the two limiting seats 524 to approach the paper roll holder 20 simultaneously. By squeezing the two free ends 201, the insulating paper strip 200 is guided to curl and form a tape mounting gap.

[0067] Understandably, after the two ends of the insulating paper strip 200 are lifted by the paper roll holder 20 to form free ends 201, the two limiting cylinders 523 respectively drive the limiting seats 524 to move in the direction closer to the paper roll holder 20 until the limiting seats 524 contact the two free ends 201 of the insulating paper strip 200. Since the limiting seats 524 are provided with arc-shaped guide surfaces 521 that match the shape of the insulating paper strip 200, when the limiting seats 524 approach and contact the insulating paper strip 200, the arc-shaped guide surfaces 521 will guide the insulating paper strip 200 to gradually curl. In this process, the two limiting seats 524 move synchronously, ensuring that the two ends of the insulating paper strip 200 can be curled evenly and stably, avoiding possible deviation or twisting during the curling process. As the degree of curling of the insulating paper strip 200 gradually increases, the gap between the two limiting seats 524 gradually decreases until a gap suitable for tape application is finally formed.

[0068] Furthermore, the tape applicator 60 includes a tape supply unit 61, a tape gripping unit 62, a tape cutting unit 63, and a tape applicator 64. The tape supply unit 61 is used to supply continuous tape, the tape gripping unit 62 is used to grip one end of the tape and cut the tape into tape strips 400 of a preset length, and the tape applicator 64 is used to attach the tape strips 400 to the top of the two free ends 201 within the tape applicator gap.

[0069] The tape supply unit 61 provides a stable and continuous tape output, while the tape gripping unit 62 precisely grips one end of the tape, ensuring stability and accuracy during cutting and application. The tape cutting unit 63 precisely cuts the tape according to preset length parameters, forming a tape strip 400 that meets the requirements. Finally, the tape application unit 64 accurately attaches the cut tape strip 400 to the tops of the two free ends 201 of the insulating paper strip 200. By attaching the tape strip 400 to the two free ends 201 of the insulating paper strip 200, the shape of the cylindrical insulating paper roll 300 remains stable.

[0070] In some specific embodiments, the tape supply unit 61 includes a tape support 611 fixedly mounted on the machine body 10 and a tape reel 612 rotatably mounted on the tape support 611. The tape gripping unit 62 includes a tape gripper 621 slidably mounted on the tape support 611, a first tape cylinder 622 for driving the tape gripper 621 to move toward or away from the tape reel 612, and a second tape cylinder 623 for driving the tape gripper 621 to open and close. The tape cutting unit 63 includes a first cutting cylinder 631 fixedly mounted on the tape support 611, a cutting blade 632 mounted on the first cutting cylinder 631, and a second cutting cylinder 633 for driving the cutting blade 632 to open and close. The first cutting cylinder 631 drives the cutting blade 632 to move toward or away from the tape pulled out by the tape gripper 621, so that the cutting blade 632 can cut the continuous tape under the drive of the second cutting cylinder 633.

[0071] When supplying tape, the second tape cylinder 623 drives the tape gripper 621 to close, clamping the free end 201 of the tape. The first tape cylinder 622 drives the tape gripper 621 to move away from the tape reel 612, pulling the continuous tape provided by the reel 612 out to a preset length. At this time, the first shearing cylinder 631 drives the shearing blade 632 to move closer to the tape. Subsequently, the second shearing cylinder 633 drives the shearing blade 632 to close, cutting the tape to obtain a tape strip 400 of the preset length. Simultaneously, by adjusting the stroke of the first shearing cylinder 631, the length of the tape strip 400 can be adjusted, allowing for the cutting of tape strips 400 of different lengths.

[0072] Furthermore, the tape application mechanism 60 includes a tape application bracket 641 fixedly mounted on the sliding seat 41, a tape application base 642 vertically mounted on the tape application bracket 641, a Z-axis cylinder 643 for driving the tape application base 642 to move vertically relative to the tape application bracket 641 along the Z-axis, and an adsorption head 644 mounted on the tape application base 642. The tape application bracket 641 is located on one side of the sliding seat 42. The Z-axis cylinder 643 drives the tape application bracket 641 to move up and down along the Z-axis. The adsorption head 644 is connected to a vacuum adsorption device 645 so that the adsorption head 644 can pick up and release the tape strip 400. It should be noted that the adhesive surface of the tape is located on the bottom side of the tape strip 400, and the adsorption head 644 picks up the tape strip 400 from the top of the tape strip 400 under the action of the vacuum adsorption device 645.

[0073] When the cut tape strip 400 needs to be applied, the Z-axis cylinder 643 is activated, driving the tape application base 642 and its suction head 644 to descend along the Z-axis to a position close to the tape cutting unit 63. At this time, the vacuum suction device 645 is activated, and the suction head 644 uses its internal negative pressure to hold the top of the tape strip 400. Then, the Z-axis cylinder 643 is activated again, driving the tape application base 642 and its suction head 644 to rise along the Z-axis to a certain height, so as to move the tape strip 400 from the cutting position to above the tape application gap. Then, the Z-axis cylinder 643 drives the tape application base 642 and its suction head 644 to descend, so that the adhesive surface of the tape strip 400 contacts the application surface (the top of the two free ends 201). Then, the vacuum suction device 645 is closed, and the suction head 644 releases the tape strip 400, completing the application of the tape strip 400.

[0074] In addition, the tape applicator 642 is also equipped with a fixing block 646, a guide rod 647, and a spring 648. The fixing block 646 is located above the suction head 644, and the guide rod 647 is vertically arranged between the fixing block 646 and the suction head 644. One end of the guide rod 647 is fixed to the fixing block 646, and the other end is inserted into the suction head 644. The spring 648 is wrapped around the guide rod 647. The arrangement of the fixing block 646, the guide rod 647, and the spring 648 allows the suction head 644 to have a certain amount of movement space when it applies the tape strip 400, thereby pressing the tape strip 400 tightly and ensuring the application quality of the tape strip 400.

[0075] It should be noted that since the tape applicator 641 is fixed on the sliding seat 41, during operation, when the X-axis moving module 46 drives the sliding seat 41 to move to the first position, the moving seat 42 is located on one side of the paper feeding mechanism 30. The first paper feeding claw and the second paper feeding claw can perform the operation of gripping the insulating paper strip 200. At this time, the tape applicator 641 is located on one side of the paper roll holder 20, and the suction head 644 is located directly above the paper roll holder 20. The suction head 644 is driven to descend vertically by the Z-axis cylinder 643, thereby completing the tape applicator operation. When the X-axis moving module 46 drives the sliding seat 41 to the second position, the moving seat 42 is located on one side of the paper roll holder 20. The first and second paper feeding grippers can transport the gripped insulating paper strip 200 to the top of the paper roll holder 20, completing the paper feeding operation. At the same time, the tape mounting bracket 641 is located at the tape supply unit 61. The suction head 644 is driven to rise and fall by the Z-axis cylinder 643, and the suction head 644 can complete the adsorption operation of the tape strip 400. This process is repeated, so that the tape mounting operation and the paper feeding operation are alternately performed at the paper roll holder 20, ensuring the continuity and stability of the entire production process, thereby improving the production efficiency of the insulating paper roll 300.

[0076] To further ensure the quality of tape application, the paper pressing assembly 51 also includes a vertical groove 515 opened on the paper pressing head 513, a pad 516 that can be lifted and lowered in the vertical groove 515, and a pad cylinder 517 for driving the pad 516 to rise and fall vertically relative to the vertical groove 515. The pad 516 is used to support the top of the inner circumferential surface of the Dingcheng insulating paper roll 300 when the tape strip 400 is applied in the tape application unit 64, and the top support position corresponds to the ends of the two free ends 201.

[0077] When the tape application unit 64 applies the tape strip 400, the pad cylinder 517 drives the pad 516 to rise vertically. This allows the pad 516 to precisely support the top of the inner circumference of the insulating paper roll 300, with the support position corresponding precisely to the ends of the two free ends 201. This ensures that the tape strip 400 is flat and firmly adhered to the insulating paper roll 300, greatly reducing production quality problems caused by poor adhesion. Simultaneously, the adjustable design of the pad 516 allows it to automatically descend when not in operation, avoiding interference with the insulating paper roll 300 or other components and ensuring the smooth operation of the entire production process.

[0078] It should be noted that when the tape strip 400 is attached to the top of the two free ends 201, there is a certain gap between the pad 516 and the two ends of the tape strip 400, to avoid the two ends of the tape strip 400 being attached to the pad 516, and also to facilitate the transfer mechanism 70 to bend the two ends of the tape strip 400 and attach them to the bottom of the two free ends 201.

[0079] Furthermore, the machine body 10 is provided with a feeding channel 11, and the transfer mechanism 70 includes a fixed frame 71 fixed on the machine body 10, a lifting seat 72 that can be raised and lowered on the fixed frame 71, a rotating frame 73 rotatably disposed on the bottom side of the lifting seat 72, a gripper seat 74 fixedly disposed on the bottom side of the rotating frame 73, a first transfer gripper 75 and a second transfer gripper 76 slidably disposed on the gripper seat 74, and a transfer gripper cylinder 77 for driving the first transfer gripper 75 and the second transfer gripper 76 to move towards or away from each other. The rotating frame 73 can rotate back and forth between the paper roll holder 20 and the feeding channel 11, and the first transfer gripper 75 and the second transfer gripper 76 cooperate to bend and attach the two ends of the adhesive strip 400 attached to the top of the two free ends 201 to the bottom of the two free ends 201.

[0080] When the tape strip 400 is attached to the top of the two free ends 201 by the tape application unit 64, the rotating frame 73 rotates to the top of the roll paper holder 20, and at the same time drives the lifting seat 72 to descend. The first transfer gripper 75 and the second transfer gripper 76 are driven to close by the transfer gripper cylinder 77, so that the first transfer gripper 75 and the second transfer gripper 76 can bend the two ends of the tape strip 400 and attach them to the bottom of the two free ends 201, completing the tape application work and keeping the shape of the insulating paper roll 300 stable. Then, the rotating frame 73 is driven to move to the top of the unloading channel 11, and the first transfer gripper 75 and the second transfer gripper 76 are driven to separate by the transfer gripper cylinder 77, so that the insulating paper roll 300 falls into the unloading channel 11, completing the unloading.

[0081] In addition, the insulating paper rolling machine provided in this application also includes a control mechanism 80, which is located on one side of the machine body 10 and is electrically connected to the paper roll holder 20, the paper feeding mechanism 30, the paper feeding mechanism 40, the paper rolling mechanism 50, the tape application mechanism 60 and the transfer mechanism 70 to control the coordinated operation of the above-mentioned mechanisms.

[0082] This application also provides a method of using an insulating paper rolling machine, applicable to the insulating paper rolling machine described above, comprising the following steps:

[0083] 101. According to production needs, the paper feeding mechanism 30 provides insulating paper strips 200 of a preset length;

[0084] 102. The paper feeding mechanism 40 conveys the insulating paper strip 200 of a preset length between the paper roll holder 20 and the paper pressing assembly 51, drives the paper roll holder 20 to rise relative to the machine body 10, and the paper roll holder 20 cooperates with the paper pressing assembly 51 to press the middle part of the insulating paper strip 200 into the paper roll groove 21 on the paper roll holder 20, so that the two ends of the insulating paper strip 200 form upward-curving free ends 201;

[0085] 103. By simultaneously pressing the two free ends 201 of the insulating paper strip 200 through the two limiting components 52, the entire insulating paper strip 200 is guided to curl into an insulating paper roll 300, and the two free ends 201 are made to be relatively parallel. At this time, the two limiting components 52 simultaneously form the tape mounting gap, and both free ends 201 are located within the tape mounting gap.

[0086] 104. The tape strip 400 is attached to the top of the two free ends 201 within the tape application gap by the tape application mechanism 60;

[0087] 105. The two ends of the tape strip 400 are attached to the bottom of the two free ends 201 by the transfer mechanism 70, and then the insulating paper roll 300 is transferred and unloaded.

[0088] Working Principle: In the production process of insulating paper roll 300, the entire equipment achieves a complete process from feeding, cutting, conveying, rolling, tape application to unloading of insulating paper through precise mechanical movements and coordinated component cooperation. First, the insulating paper is pulled out to a preset length and precisely cut by the paper feeding mechanism 30, and then conveyed to the roll holder 20 by the paper feeding mechanism 40. On the roll holder 20, the insulating paper is pressed and rolled, forming free ends 201 at both ends, which are relatively parallel. Subsequently, the limiting component 52 guides and rolls these two free ends 201, preparing for tape application. The tape application mechanism 60 is responsible for supplying, cutting, and applying the tape, ensuring that the tape can be flat and firmly attached to the top of the two free ends 201 of the insulating paper roll 300. Finally, the transfer mechanism 70 bends and attaches both ends of the tape strip 400 to the bottom of the two free ends 201 of the insulating paper roll 300, and transfers the attached insulating paper roll 300 to the unloading channel 11 to complete the production of the entire insulating paper roll 300.

[0089] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be covered within the scope of the claims of the present invention.
