Description

TECHNICAL FIELD

[0001] The application relates to the technical field of adhesive tape production, and in particular to an automatic production device and method for waterproof insulating film adhesive tape. BACKGROUND

[0002] The waterproof insulating adhesive tape is a special electrician's adhesive tape, which is specially designed to provide excellent waterproof and electrical insulation performance, especially for protecting wire joints, cable ends and electrical connection points in outdoor or humid environments. It is usually made of low modulus and high elasticity materials. The thinning + rebound sealing capacity under tension is a functional strength (dynamic sealing strength) that cannot be achieved by traditional adhesive tapes. The production process of the waterproof insulating adhesive tape includes unwinding (pretreatment of the base material), coating and curing, slitting and winding, and packaging. The slitting and winding usually uses an automatic slitting device.

[0003] The common automatic slitting device includes a release shaft, a guide shaft (part of the guide shaft is provided with a cutter), and a winding shaft. After the adhesive tape paper tube is fixed equidistantly on the winding shaft, the adhesive tape is guided onto the adhesive tape paper tube. Then, the release shaft and the winding shaft are driven to rotate by the driving device, so that the wide adhesive tape is cut into small wide adhesive tapes by the cutter during the winding process and is wound on the adhesive tape paper tube. The automatic slitting device usually has multiple winding shafts, and the multiple winding shafts are independently driven to rotate. When the amount of adhesive tape on the adhesive tape paper tube is sufficient, the operator will switch the winding shaft on the winding station, so that the empty adhesive tape paper tube is moved to the winding station, and the full roll of adhesive tape is moved to the material returning station for material returning and feeding.

[0004] The waterproof insulating adhesive tape usually uses low modulus and high elasticity materials, and the automatic slitting device is provided with a tension adjusting system. Under the intervention of the tension adjusting system, the adhesive tape can be prevented from being wrinkled due to relaxation after winding, and the adhesive tape can also be prevented from being too tight to affect the functional strength due to the thinning of the adhesive tape thickness. The tension adjusting system usually adopts a dynamic matching mode of controlling the rotation speed of the winding shaft and the rotation speed of the release shaft to control the tension.

[0005] Since the multiple winding shafts of the common automatic slitting device are independently driven to rotate, the multiple independent motors and their driving systems inevitably have slight speed following errors, torque response differences, and even encoder feedback errors. At the critical moment when the new and old shafts contact the adhesive tape together, or just complete the material feeding or tension transfer, any slight mismatch in linear speed or torque fluctuation will directly destroy the tension stability, which may affect the production quality of the adhesive tape, such as increasing the burr of the cutout. The driving systems of the multiple winding shafts and the tension adjusting system are logically connected, which increases the operation pressure of the tension adjusting system. Long-term high-intensity operation may cause system collapse and lead to production stagnation. SUMMARY

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0030] Please see Figures 1-9 In this embodiment of the invention, an automatic production device for waterproof insulating film tape includes a housing 1; a release shaft 101 and multiple sets of guide shafts 102 are rotatably mounted on the housing 1; an mounting plate 2 is mounted on the housing 1; a fixing rod 201 and a winding motor 4 are mounted on the mounting plate 2. Further comprising a driving shaft 5; the output end of the winding motor 4 is fixedly connected with the driving shaft 5, and the end of the driving shaft 5 is provided with an arc-shaped slot 501; A plurality of winding shafts 3, both ends of the winding shaft 3 are provided with an embedded block 301; A plurality of supporting members, comprising a rotating supporting shaft 8; one end of the supporting shaft 8 is provided with an arc-shaped block 801 which is clamped with the arc-shaped slot 501; and the other end is provided with an embedded slot 802 which is clamped with the embedded block 301; Further comprising a switching member, the switching member can drive the supporting shaft 8 to rotate along the circumference of the mounting disc 2, so that one supporting shaft 8 is disengaged from the driving shaft 5; and another supporting shaft 8 is engaged with the driving shaft 5.

[0031] In use, the release shaft 101 is used to fix the wide adhesive tape roll, when rotating, the wide adhesive tape can be released; or cooperates with the guide shaft 102 to guide the wide adhesive tape to move forward and control the tension of the adhesive tape. During the movement of the adhesive tape, the blades on part of the guide shaft 102 will uniformly and stably cut the wide adhesive tape, so as to obtain a small wide adhesive tape.

[0032] When the winding motor 4 rotates, it drives the driving shaft 5 to rotate, thereby driving the supporting shaft 8 which cooperates with it (the arc-shaped slot 501 is clamped with the arc-shaped block 801) to rotate, thereby driving the winding shaft 3 which cooperates with the supporting shaft 8 (the embedded slot 802 is clamped with the embedded block 301) to rotate, so as to uniformly wind the small wide adhesive tape on the adhesive tape paper tube. During this process, the adhesive tape only cooperates with one winding shaft 3.

[0033] When one winding shaft 3 completes the winding amount of the adhesive tape, the control system in the cabinet 1 controls the winding motor 4 to stop rotating, and controls the switching member to act.

[0034] When the switching member acts, it drives a plurality of supporting members to rotate along the circumference of the mounting disc 2; to complete the switching action; wherein the switching member first drives the supporting member which does not contact with the adhesive tape to rotate, thereby driving the winding shaft 3 thereon to gradually approach and abut against the adhesive tape (the adhesive tape is adhered with the adhesive tape paper tube on this winding shaft 3); and after abutting, the operator cuts off the adhesive tape by the disconnecting tool (the cut is located between the two winding shafts 3).

[0035] After the winding shaft 3 abuts against the adhesive tape, the switching member drives two supporting members to act synchronously, to drive the supporting member which cooperates with the driving shaft 5 to gradually separate from the driving shaft 5, and to drive the other supporting member to gradually approach the driving shaft 5 and cooperate with it.

[0036] And after the cooperation, the switching piece drives the receiving piece separated from the driving shaft 5 to rotate, thereby conveying the finished adhesive tape to the material returning station. At this time, the operator replaces the new winding shaft 3 by the cooperation of the embedded block 301 and the embedded groove 802, and takes out the finished adhesive tape from the replaced winding shaft 3. During the process, the driving shaft 5 rotates again to drive the winding shaft 3 to rotate, thereby continuing the winding action.

[0037] Since the adhesive tape breakage is located between the two winding shafts 3, and the winding shaft 3 is adhered to the adhesive tape when cutting, the overall tension of the adhesive tape in the production device fluctuates less when cutting, thereby reducing the influence of the tension on the quality of the adhesive tape.

[0038] One driving shaft 5 can be alternately cooperated with multiple receiving pieces through the switching piece, and the unique driving source ensures that only one winding shaft 3 receives the driving torque at all time periods; and the torque forces received by the multiple winding shafts 3 are basically the same; the error caused by the coordination of two independent systems is fundamentally eliminated, thereby providing higher synchronization and dynamic tension stability, especially at the switching moment.

[0039] In another embodiment of the present application, the receiving piece further comprises a rotating sleeve 6 rotatably installed on the fixed rod 201; and multiple groups of the rotating sleeve 6 are symmetrically arranged; the rotating sleeve 6 is installed with a mounting frame 7, and the receiving shaft 8 is rotatably installed on the mounting frame 7; the receiving shaft 8 is slidably installed with a sliding sleeve 25, and the sliding sleeve 25 cooperates with the embedded groove 802; the receiving shaft 8 is wrapped with a first spring 12; and the two ends of the first spring 12 respectively abut against the sliding sleeve 25 and the receiving shaft 8.

[0040] In the use of the embodiment combining all the features described in the present application, in the initial position, one receiving shaft 8 cooperates with the driving shaft 5 (this receiving shaft 8 is named as “working shaft”), and the other receiving shaft 8 does not cooperate with the driving shaft 5 (this receiving shaft 8 is named as “standby shaft”), and the standby shaft is located on the material returning station. When the driving shaft 5 rotates, it drives the working shaft to rotate through the abutting cooperation of the arc-shaped notch 501 and the arc-shaped block 801, thereby performing the winding action.

[0041] When replacing the winding shaft 3 to take out the full roll of adhesive tape or replace the new adhesive tape paper tube, an external force is applied to drive the sliding sleeve 25 to slide towards the mounting frame 7 and compress the first spring 12. During the process, the sliding sleeve 25 gradually separates from the embedded groove 802, so that the embedded block 301 can freely slide in the embedded groove 802, thereby completing the separation and cooperation.

[0042] When the new embedded block 301 on the winding shaft 3 is clamped with the embedded groove 802, the external force is removed, and under the elastic force of the first spring 12, the sliding sleeve 25 gradually moves away from the mounting frame 7 and cooperates with the embedded groove 802 to limit the sliding of the embedded block 301 in the embedded groove 802, so that the winding shaft 3 is stably connected with the receiving shaft 8. The difficulty of taking down the full roll of adhesive tape can be reduced, and the work efficiency can be improved.

[0043] In another embodiment of the application, the receiving shaft 8 is provided with a fixed block 9 at one end of the arc-shaped block 801, and the fixed block 9 is provided with an inclined groove 901 and a straight groove 902; the two ends of the inclined groove 901 are communicated with the straight groove 902, and the groove wall on one side penetrates the fixed block 9; the receiving shaft 8 is provided with a sliding ring 11; the sliding ring 11 is provided with a top rod 1101 which cooperates with the inclined groove 901 and the straight groove 902; the mounting frame 7 is provided with a gas cylinder 10; the output end of the gas cylinder 10 is fixedly connected with the sliding ring 11.

[0044] In use, the gas cylinder 10 is controlled by a control system.

[0045] The fixed block 9 on the working shaft is in a separated state with the sliding ring 11, so that when the driving shaft 5 rotates, the working shaft can be driven to rotate.

[0046] When the adhesive tape on the winding shaft 3 connected with the working shaft is full, the control system drives the gas cylinder 10 to act, thereby driving the sliding ring 11 to approach the fixed block 9; during the process, the top rod 1101 moves synchronously; the top rod 1101 has two contact conditions with the fixed block 9: condition one: the top rod 1101 directly enters the straight groove 902, and through the resistance cooperation of the top rod 1101 and the straight groove 902, the rotation of the working shaft (the rotation center is located on the axis of the working shaft) can be limited, and at this time, the arc-shaped missing groove 501 is concentric with the fixed rod 201. Condition two: the top rod 1101 first contacts the inclined groove 901, and through the extrusion of the top rod 1101 on the groove wall of the inclined groove 901, the fixed block 9 can be driven to rotate, thereby driving the working shaft to rotate the driving shaft 5; when the top rod 1101 enters the straight groove 902 along the groove wall of the inclined groove 901, the arc-shaped missing groove 501 is concentric with the fixed rod 201.

[0047] Then the switching piece acts to drive the receiving piece to rotate, thereby separating the working shaft from the driving shaft 5 (the arc-shaped block 801 slides away from the arc-shaped missing groove 501).

[0048] Through the cooperation of the jacking rod 1101 and the inclined groove 901 and the straight groove 902, the resistance of the working shaft and the driving shaft 5 can be reduced, and the equipment can be prevented from being damaged; and through the extrusion cooperation of the jacking rod 1101 and the straight groove 902, the position deviation of the arc-shaped block 801 caused by self-rotation due to external interference (mechanical vibration, gravity, inertia, etc.) in the switching process of the working shaft and the standby shaft can be avoided, so that the device is prevented from being damaged by rigid collision.

[0049] In another embodiment of the application, the switching member comprises a switching motor 13 mounted on the mounting disc 2; a first gear 14 is mounted on the output end of the switching motor 13; a connecting sleeve 15 is rotatably mounted on the fixed rod 201, and a second gear 16 and a connecting rod 17 are mounted on the connecting sleeve 15 and mesh with the first gear 14; a sliding rod 18 is slidably mounted on the connecting rod 17 and can abut against the mounting frame 7.

[0050] In another embodiment of the application, the switching member further comprises a second spring 19 wrapped around the sliding rod 18, and the two ends of the second spring 19 abut against the connecting rod 17 and the sliding rod 18, respectively; a roller 20 is rotatably mounted on the end of the sliding rod 18; and a fixed ring 21 is mounted on the mounting disc 2 and rolls with the roller 20; a notch 2101 is formed in the fixed ring 21.

[0051] In another embodiment of the application, one side of the notch 2101 is perpendicular to the mounting disc 2 and cooperates with the driving shaft 5; and the other side of the notch 2101 is inclined.

[0052] In use, in the switching process, the switching motor 13 drives the first gear 14 to rotate, and drives the second gear 16 to rotate through meshing, so as to drive the connecting sleeve 15 to rotate, thereby driving the connecting rod 17 to rotate.

[0053] When the connecting rod 17 rotates, the sliding rod 18 is driven to rotate, thereby driving the mounting frame 7 connected to the standby shaft to rotate through the extrusion of the sliding rod 18, so as to drive the rotating sleeve 6 to rotate on the fixed rod 201, thereby driving the winding shaft 3 on the standby shaft to approach and abut against the adhesive tape.

[0054] Then, the sliding rod 18 drives the mounting frame 7 connected to the working shaft and the mounting frame 7 connected to the standby shaft to rotate synchronously, thereby driving the working shaft to separate from the driving shaft 5 and driving the standby shaft to approach the driving shaft 5; when the standby shaft cooperates with the driving shaft 5, the standby shaft becomes the working shaft, and the old working shaft becomes the standby shaft.

[0055] In the process, the roller 20 rolls on the top surface of the fixed ring 21, so that the second spring 19 is in a compressed state, so that the slide bar 18 is always in contact with the mounting frame 7. When the standby shaft cooperates with the driving shaft 5, the roller 20 is disengaged from the top surface of the fixed ring 21, and under the action of the elastic force of the second spring 19, it is close to the inclined surface along the vertical surface of the slot 2101, at this time the slide bar 18 slides inwards on the connecting rod 17 and is disengaged from the new working shaft.

[0056] After the slide bar 18 continues to rotate, the roller 20 will roll on the inclined surface, and through the extrusion of the inclined surface on the roller 20, the slide bar 18 slides outwards on the connecting rod 17, and the second spring 19 is compressed; until the roller 20 is disengaged from the inclined surface and cooperates with the top surface. After that, the slide bar 18 continues to rotate and will be in contact with the mounting frame 7 of the old working shaft during the rotation process, and after the contact, the old working shaft is moved to the material returning station.

[0057] One driving shaft 5 can be alternately matched with multiple receiving members through the switching member, and the only driving source ensures that only one winding shaft 3 receives driving torque at all times; and the torque forces received by the multiple winding shafts 3 during winding are basically the same; fundamentally eliminating the error caused by the coordination of two independent systems, providing higher precision synchronization and dynamic tension stability, especially at the switching moment.

[0058] In another embodiment of the application, the rotating sleeve 6 is provided with abutting blocks 601 which abut against each other, and a gap is left between the abutting blocks 601.

[0059] In use, for example, in the embodiment combining all the features described in the application, when the standby shaft rotates along the circumference of the mounting disc 2, the rotating sleeve 6 will rotate synchronously, thereby driving the abutting block 601 to approach the other abutting block 601 to shorten the gap.

[0060] When the winding shaft 3 on the standby shaft abuts against the adhesive tape, the two abutting blocks 601 abut against each other and the gap disappears. Then, when the standby shaft rotates, it will drive the other rotating sleeve 6 to rotate through the abutting action of the two abutting blocks 601, thereby driving the working shaft to rotate along the circumference of the mounting disc 2, so that the working shaft is separated from the driving shaft 5, and the standby shaft cooperates with the driving shaft 5, completing the replacement of the standby shaft and the working shaft.

[0061] Then, when the old working shaft rotates, it will drive the abutting block 601 connected thereto to gradually move away from the other abutting block 601, thereby expanding the gap.

[0062] Through the arrangement of the two abutting blocks 601 and the gap, the position deviation of the working shaft during the abutting process of the winding shaft 3 on the standby shaft and the adhesive tape can be avoided, so as to balance the system tension and improve the product quality.

[0063] Another embodiment of the present application, the rotating sleeve 6 is installed with a locking ring 602; the fixed rod 201 is slidingly installed with a limiting ring 22; the limiting ring 22 and the locking ring 602 are both installed with a plurality of sets of tooth blocks 23 that are mutually engaged, the fixed rod 201 is wrapped with a third spring 24, and the two ends of the third spring 24 are respectively in contact with the limiting ring 22 and the fixed rod 201.

[0064] In use, the rotating sleeve 6 rotates under the extrusion fit of the slide rod 18 and the mounting frame 7, which drives the locking ring 602 to rotate synchronously. During this process, the limiting ring 22 is extruded to slide away from the locking ring 602 and the third spring 24 is compressed through the mutual contact of the tooth blocks 23. After the tooth blocks 23 pass another tooth block 23, the elastic force of the third spring 24 drives the limiting ring 22 to approach the locking ring 602, so that the plurality of sets of tooth blocks 23 are re-engaged.

[0065] During the winding process, the elastic force of the third spring 24 increases the engagement force between the tooth blocks 23, which can prevent the spare shaft and the working shaft from being misaligned and causing equipment failure.

[0066] In another embodiment of the present application, a plurality of grooves are formed on the sliding sleeve 25.

[0067] In use, the embodiments combined with all the features described in the present application increase the surface friction coefficient of the sliding sleeve 25 to reduce the difficulty of replacing the winding shaft 3.

[0068] A method for producing a waterproof insulation film adhesive tape using the automatic production device described above, comprising the following steps: Step one: unwinding, using an automatic unwinding machine to uniformly unwind the base material, (the running angular velocity of the unwinding machine changes constantly with the thickness of the base material) to uniformly pretreat the base material during unwinding; Step two: coating and curing, using a coating device to coat the pretreated base material unwound by the automatic unwinding machine, uniformly applying waterproof insulation adhesive to the base film, (using a doctor blade coating method for uniform coating), and using a drying device (specifically using a segmented temperature control drying tunnel for drying, with a drying temperature of 80℃) to cure the adhesive coated on the base film; Step three: slitting and winding, using the automatic production device for waterproof insulation film adhesive tape to slit and wind the wide adhesive tape with adhesive coated and cured on the surface, to obtain a small-width adhesive tape; Step four: packaging, packaging the small-width adhesive tape product after slitting and winding.
