[0034] Embodiment 1

[0035] In some embodiments, please refer to the attached instructions. Figure 1-6 , an unwinding device that is easy to operate, comprising a control cabinet 10, a belt connection mechanism 20 and a material moving mechanism 30 arranged at the front side of the control cabinet 10 for replacing a barrel 40;

[0036] The front side of the control cabinet 10 is provided with a guide roller 11, a tension swing rod 12 and a traction roller 13 in sequence along the unwinding direction of the insulating paper. The tension swing rod 12 and the traction roller 13 are both made of common technical means in the art;

[0037] The tape connection mechanism 20 includes a carrier plate 21, a material discharge assembly, an auxiliary pressing assembly and a glue spraying device 29. The carrier plate 21 is rotatably connected to the control cabinet 10 through a bearing, and the carrier plate 21 can be driven to rotate by a motor or a cylinder arranged in the control cabinet 10; the two ends of the carrier plate 21 are symmetrically provided with material discharge assemblies; the top of the control cabinet 10 is provided with an auxiliary pressing assembly for making the new and old tapes fit tightly;

[0038] The material transfer mechanism 30 is provided with a plurality of glue spraying devices 29 for spraying adhesive liquid onto the insulating paper on the barrel 40 ; the glue spraying device 29 is composed of an electrically controlled injection valve and a heated glue storage tank to achieve a quantitative glue spraying function.

[0039] In the present invention, after the right-side unloading assembly unloads the insulating paper from the barrel 40, the insulating paper passes through the tension swing rod 12, the guide roller 11 and the traction roller 13 in sequence, the unloaded insulating paper is transported by the traction roller 13, and the tension of the insulating paper strip is controlled by the tension swing rod 12;

[0040] When the insulating paper of the upper barrel 40 of the right-side unloading component is about to be discharged, glue is sprayed onto the insulating paper of the upper barrel 40 of the left-side unloading component through the glue spraying device 29, and then the unloading component is driven to rotate 180 degrees counterclockwise through the carrier plate 21. During the rotation process, the insulating paper of the original unloading component on the right side will gradually adhere to the insulating paper of the unloading component on the left side, until the barrels 40 of the two groups of unloading components completely exchange positions. At this time, the old insulating paper is pressed tightly against the insulating paper of the new barrel 40 through the auxiliary pressing component, and the barrel 40 is controlled to rotate at the same time, so that the old insulating paper and the new insulating paper are completely bonded, realizing the automatic splicing operation of the new and old insulating papers, effectively improving the efficiency of splicing and material replacement, reducing the possibility of position deviation of the insulating paper caused by artificial splicing, and ensuring the accurate unwinding of the insulating paper;

[0041] After the tape splicing operation is completed, the material barrel 40 that has run out of insulating paper can be automatically removed from the unwinding assembly through the material moving mechanism 30. At this time, only a new material barrel 40 needs to be placed on the material moving mechanism 30, and the material barrel 40 can be automatically loaded onto the unwinding assembly through the material moving mechanism 30, which is convenient for personnel operation, reduces equipment standby time during roll changing, and improves the efficiency of unwinding insulating paper.

[0042] The unwinding assembly includes a servo motor 22 and an unwinding roller 23. The unwinding roller 23 is rotatably mounted on the front of the carrier plate 21 through a bearing. The servo motor 22 is fixedly mounted on the back of the carrier plate 21. The output end of the servo motor 22 is fixedly connected to the unwinding roller 23. The servo motor 22 can control the servo rotation of the unwinding roller 23 to accurately control the unwinding length of the insulating paper. The servo motor 22 is tilted to reduce the overall occupied space when the carrier plate 21 rotates.

[0043] The auxiliary clamping assembly includes a bracket 24, a cylinder 25, a vertical moving plate 26, a spring telescopic rod 27 and a pressing plate 28. The bracket 24 is fixedly installed on the top of the control cabinet 10, the cylinder 25 is fixedly connected to the bracket 24, and the output end of the cylinder 25 is fixedly installed with the vertical moving plate 26; the spring telescopic rod 27 is composed of an outer sliding sleeve and an inner sliding rod arranged in a sliding sleeve, and a spring is provided between the outer sliding sleeve and the inner sliding rod; the outer sliding sleeve of the spring telescopic rod 27 is fixedly connected to the vertical moving plate 26, and the inner sliding rod of the spring telescopic rod 27 is fixedly connected to the pressing plate 28; the pressing plate 28 is set to be an arc shape that fits tightly with the insulating paper tape on the barrel 40; the vertical moving plate 26 is driven vertically by the cylinder 25, and the pressing plate 28 can be driven vertically downward by the spring telescopic rod 27, so that the old insulating paper is pressed tightly on the insulating paper of the new barrel 40, so that the new and old insulating papers are tightly bonded by the glue, thereby improving the stability of the joint tape.

[0044] The material moving mechanism 30 includes a linear guide 31, a base plate 32, a lifting cylinder 33, a supporting plate 34 and a push plate 35. The linear guide 31 is arranged at the lower side of the discharge roller 23. The base plate 32 is limitedly slidably connected with the linear guide 31 through a slider, and can be pushed by manpower or driven by a cylinder to move horizontally; the supporting plate 34 is moved up and down by the lifting cylinder 33 arranged on the base plate 32; the upper end of the supporting plate 34 is provided with an arc-shaped groove that fits the barrel 40, and the front and rear ends of the supporting plate 34 are fixedly installed with a push plate 35, and the upper end of the push plate 35 is set to an arc shape that fits the discharge roller 23; the supporting plate 34 and the push plate 35 constitute a supporting structure for the barrel 40;

[0045] The supporting plate 34 is driven to move vertically upward by the lifting cylinder 33 so that the top of the push plate 35 is in contact with the discharge roller 23, and then the bottom plate 32 is moved horizontally to push the barrel 40 that has used up the insulation paper from the discharge roller 23 through the push plate 35, so that the old barrel 40 can be taken out; after placing the new barrel 40 in the supporting structure, the barrel 40 is pushed, and the barrel 40 can be installed on the discharge roller 23, which facilitates the manual loading operation.

[0046] The glue spraying device 29 is fixedly mounted on the bottom plate 32 , and a through slot 36 for accommodating the glue spraying device 29 is provided at the bottom of the supporting plate 34 . When a new barrel 40 is placed in the supporting structure, the glue spraying device 29 can normally spray glue onto the insulating paper of the barrel 40 through the through slot 36 .

[0047] The specific working steps of the unwinding equipment are as follows:

[0048] Step 1: When the insulating paper on the barrel 40 on the right side of the carrier 21 is about to run out, the end of the insulating paper is still connected to the barrel 40, and the glue spraying device 29 sprays glue onto the surface of the insulating paper on the barrel 40 on the left side;

[0049] Step 2: The carrier plate 21 rotates 180 degrees counterclockwise, and the tension swing rod 12 moves synchronously to reduce the tensioning effect on the insulation paper so that the barrel 40 can smoothly pull the insulation paper on the right side;

[0050] Step 3: During the rotation of the carrier plate 21, the insulating paper of the original right barrel 40 will gradually adhere to the insulating paper on the surface of the left barrel 40. When the two groups of barrels 40 are completely exchanged, because the left barrel 40 is lower than the right barrel 40, the old insulating paper is pressed tightly against the insulating paper on the surface of the new barrel 40 under the tensioning cooperation of the tension swing rod 12;

[0051] Step 4: The cylinder 25 drives the vertical moving plate 26 to move vertically, so that the spring telescopic rod 27 drives the pressing plate 28 to move vertically downward, and the old insulating paper is pressed tightly against the insulating paper of the new barrel 40, so that the new and old insulating papers are tightly bonded by the glue;

[0052] Step 5: The insulating paper is conveyed by the traction roller 13, and the tension swing rod 12 gradually tightens the insulating paper. At the same time, the servo motor 22 controls the old barrel 40 to completely release the insulating paper, controls the new barrel 22 to unwind, and the old insulation and the new insulation paper are completely bonded under the action of the pressing plate 28;

[0053] Step 6: When the insulating paper on the old barrel 40 is completely released, the operator cuts and separates the end of the insulating paper from the old barrel 40, and then drives the supporting plate 34 to move vertically upward through the lifting cylinder 33 so that the top of the push plate 35 is in contact with the discharge roller 23, and then moves the bottom plate 32 horizontally to push the barrel 40 with no insulating paper from the discharge roller 23 through the push plate 35, so as to remove the old barrel 40.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
