[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0033] In one embodiment, reference Figures 1-10, an automatic cutting and laminating device for cable packaging tape, including a workbench 1, the workbench 1 is fixedly connected to a fixed frame 2 by a driving part, and further includes: a packaging part 3 arranged on the side wall of the fixed frame 2, the packaging part 3 is used to wrap the tape around the packaging workpiece; a pre-processing mechanism 4, which rotates on the other side of the fixed frame 2, wherein the pre-processing mechanism 4 includes an annular gear ring 41 rotatably arranged on the other side of the fixed frame 2, and three groups of telescopic cylinders 42 are fixedly connected to the interior of the annular gear ring 41, and the tops of the three groups of telescopic cylinders 42 are fixedly connected to a concave seat 43, and the inner wall of the concave seat 43 is rotated by a rotating shaft The cleaning rollers 44 are connected to form a triangular area between the cleaning rollers 44, and the workpiece is located in the triangular area for surface pretreatment; the cutting mechanism 5 is fixed on one side of the annular gear ring 41, and is used to cut the tape after packaging. The telescopic cylinder 42 is composed of a limiting cylinder 421, a telescopic rod 422 and a support spring 423. The limiting cylinder 421 is internally slidably connected to the telescopic rod 422, and the support spring 423 is fixedly connected between the limiting cylinder 421 and the telescopic rod 422. The front of the workbench 1 is fixedly connected to the auxiliary roller 11, and the auxiliary roller 11 is symmetrically arranged along the center line of the fixed frame 2.

[0034] By adopting such a solution, the pretreatment mechanism 4 is set up so that the surface of the workpiece can be stably transported and pretreated at the same time, thereby removing impurities on the surface of the workpiece and preventing bubbles from being easily generated due to impurities during the subsequent tape packaging. Bubbles will cause the tape to fall off easily, especially when the cable is bent or subjected to external force, which may cause the tape to lose its protective or fixing effect, thereby affecting the work quality of the tape packaging.

[0035] During specific work, the workbench 1 is used to support the fixed frame 2, and then the fixed frame 2 is used to support the packaging part 3, the pretreatment mechanism 4 and the cutting mechanism 5 respectively. When the workpiece needs to be wrapped with tape, one end of the workpiece is first inserted into one side of the pretreatment mechanism 4 and then comes out from one side of the fixed frame 2. Under the setting of the pretreatment mechanism 4, the surface of the workpiece can be pretreated. After the surface of the workpiece is pretreated, the efficiency of the subsequent fixed frame 2 wrapping the workpiece with tape is better. The three sets of telescopic cylinders 42 are supported by the annular gear ring 41, and then the telescopic cylinder 42 is used to support the telescopic cylinder 42 and the cleaning roller 4. 4 supports, through the triangular area formed between the cleaning rollers 44, the triangular support has stability, thereby ensuring the stability of the workpiece during transportation, and automatically adjusting the distance between the cleaning rollers 44 connected to the concave seat 43 through the telescopic cylinder 42, so as to ensure that the cleaning rollers 44 can be closely fitted to the surface of the workpiece for pre-treatment. When the annular gear ring 41 rotates, it can drive the telescopic cylinder 42, the concave seat 43 and the cleaning rollers 44 to rotate synchronously. When the cleaning rollers 44 rotate, they will perform circumferential pre-treatment along the surface of the workpiece, and as the workpiece moves, other parts of the workpiece can be continuously pre-treated synchronously, so as to ensure the fit of the tape wrapped around the fixing frame 2;

[0036] The limiting cylinder 421 is used to guide and limit the telescopic rod 422. Then, the support spring 423 between the limiting cylinder 421 and the telescopic rod 422 can be set to compress and reset according to the force applied on the telescopic rod 422, thereby ensuring the fit between the concave seat 43 on the top of the telescopic rod 422 and the cleaning roller 44 and the surface of the workpiece.

[0037] With the auxiliary roller 11 on the top of the workbench 1, the bottom of the workpiece can be supported and the workpiece can be prevented from loosening, so that the balance can be maintained when the workpiece is packaged. At the same time, it can also assist in conveying the workpiece, thereby improving the efficiency of workpiece conveying.

[0038] It should be noted that the fixed frame 2 is connected to the workbench 1 through a driving part, and the driving part is a cylinder. When workpieces of different sizes are placed above the auxiliary roller 11, the workpiece and the fixed frame 2 are not in a concentric straight line. Therefore, the fixed frame 2 can be adjusted to move up and down through the cylinder to place the workpiece in the axial position of the fixed frame 2, thereby ensuring the operation of the later packaging part 3 and the pretreatment mechanism 4.

[0039] In one embodiment, reference Figure 3 and Figure 4 The packaging part 3 includes a winding wheel 31 arranged on the side wall of the fixed frame 2, and the front of the winding wheel 31 is fixedly connected to the mounting rod 311. Several limiting wheels 32 and slave synchronous wheels 33 are respectively attached to the four sides of the winding wheel 31. The limiting wheel 32 and the slave synchronous wheels 33 are both rotatably connected to the side wall of the fixed frame 2. The side wall of the fixed frame 2 is rotatably connected to the main synchronous wheel 34 through the driving part. The main synchronous wheel 34 and the several slave synchronous wheels 33 are rotatably connected through a synchronous belt. The ends of the several slave synchronous wheels 33 all pass through the fixed frame 2 and are fixedly connected to the driving gear 331. The several driving gears 331 are meshed with the side wall of the annular gear ring 41.

[0040] With such a solution, the packaging portion 3 can be arranged to wrap the packaging tape around the surface of the workpiece in a uniform circular rotation, thereby improving the consistency of the tape packaging.

[0041] During specific operation, the winding wheel 31 is installed on the surface of the fixing frame 2, and then the winding wheel 31 can be limited on all sides by the setting of several limiting wheels 32 and slave synchronous wheels 33. Then, the tape roll can be installed by the setting of the mounting rod 311 on the surface of the winding wheel 31. When the workpiece surface needs to be wrapped with tape, one end of the tape is first adhered to the surface of the workpiece, and then the main synchronous wheel 34 is driven to rotate by the driving part. The main synchronous wheel 34 and the several slave synchronous wheels 33 are connected by a synchronous belt. Therefore, the main synchronous wheel 34 can synchronously drive the several slave synchronous wheels 33 to rotate synchronously. The rotation of the several slave synchronous wheels 33 synchronously drives the winding wheel 31 to rotate. During the rotation of the winding wheel 31, the tape roll on the surface of the mounting rod 311 will be driven to rotate in a circle and be wrapped around the surface of the workpiece for packaging.

[0042] When the slave synchronous wheel 33 rotates, the driving gear 331 can be driven to rotate synchronously. Since the driving gear 331 is engaged with the surface of the annular gear ring 41, the annular gear ring 41 can be driven to rotate synchronously, thereby ensuring the consistency of the rotation speed of the annular gear ring 41 and the winding wheel 31.

[0043] In addition, notches are provided above the fixing frame 2, the winding wheel 31 and the annular gear ring 41. Through the provision of the notches, the workpiece can be directly taken out from the notches, thereby improving the operability of the device.

[0044] In one embodiment, reference Figure 6 、 Figure 7 and Figure 8 A preheating assembly 45 is provided on the front of the annular gear ring 41, wherein the preheating assembly 45 includes a mounting plate 451 that is detachably mounted on the front of the annular gear ring 41, and a dust suction fan 452 and a heating box 453 are fixedly connected to the front of the mounting plate 451, respectively. The dust suction fan 452 is connected to the interior of the mounting plate 451, and the dust suction fan 452 is connected to the interior of the heating box 453 through a pipeline, and an exhaust pipe 454 is fixedly connected to the surface of the heating box 453.

[0045] During specific operation, under the setting of the preheating component 45, an adsorption force can be generated on the annular gear ring 41, the telescopic cylinder 42 and the concave seat 43. Under the action of the adsorption force, the dust adhered to the surface of the cleaning roller 44 can be adsorbed and processed, so that the dust adhered to the surface of the cleaning roller 44 can be adsorbed and processed centrally to prevent the dust from accumulating together; the mounting plate 451 is detachably connected to the annular gear ring 41, and the mounting plate 451 and the annular gear ring 41 can be disassembled, so that the dust collected in the annular gear ring 41 can be discharged centrally later, and the surface dust suction fan 452 of the mounting plate 451 is driven to generate an adsorption force on the annular gear ring 41, the telescopic cylinder 42 and the concave seat 43, so as to adsorb the dust on the surface of the cleaning roller 44, and then the adsorbed dust will accumulate in the annular gear ring 41 for centralized collection;

[0046] The gas exhausted by the dust suction fan 452 will be transported to the inside of the heating box 453 through the pipeline, and the gas can be heated by the heating box 453, and the heated gas will be discharged through the exhaust pipe 454. Since the exhaust pipe 454 is located on the side of the workpiece, the side of the workpiece can be preheated, and when the annular gear ring 41 rotates, the exhaust pipe 454 is synchronously driven to rotate, so that the preheating treatment can be evenly performed along the surface of the workpiece. By preheating the surface of the workpiece, it is convenient to heat the adhesive of the tape to soften it when the tape is wrapped around the surface of the workpiece later, thereby enhancing the fluidity of the tape adhesive and making it easier to penetrate into the microscopic pores on the surface of the workpiece to form mechanical anchoring and improve adhesion.

[0047] It should be noted that a filter is provided between the mounting plate 451 and the annular gear ring 41 , which can separate the gas and dust, thereby accumulating the dust inside the annular gear ring 41 , and the gas is transported to the inside of the heating box 453 through a pipe.

[0048] In one embodiment, reference Figures 1-8 The top of the concave seat 43 is fixedly connected with a scraper 431 and a baffle 432 , the baffle 432 is located on both sides of the scraper 431 , and the scraper 431 is attached to the surface of the cleaning roller 44 .

[0049] By adopting such a solution, under the setting of the scraper 431 at the top of the pretreatment mechanism 4, the dust adhering to the surface of the cleaning roller 44 can be cleaned in time, so that the cleaning roller 44 is in the best working state, avoiding the dust adhering to the surface of the cleaning roller 44 and affecting the cleaning effect of the workpiece surface in the later stage.

[0050] During specific operation, through the setting of the scraper 431 on the top of the concave seat 43, since the scraper 431 is located directly below the cleaning roller 44 and fits together, after the cleaning roller 44 rotates one circle to clean the dust on the workpiece surface, the dust adhering to the surface of the cleaning roller 44 can be scraped off and cleaned, so that the cleaning roller 44 can be restored to the best cleaning state, avoiding the dust adhering to the cleaning roller 44 affecting the next workpiece surface to play a position cleaning effect, and the baffle 432 is located on both sides of the scraper 431, which can block both sides of the scraper 431, thereby reducing the problem of dust cleaned by the scraper 431 falling again.

[0051] In one embodiment, reference Figures 1-8 The cutting mechanism 5 includes a connecting plate 51 fixed to one side of the annular gear ring 41, the top of the connecting plate 51 is fixedly connected to a moving cylinder 52, the output end of the moving cylinder 52 is fixedly connected to an L support plate 53, the top of the L support plate 53 is fixedly connected to a limiting cylinder 54, the output end of the limiting cylinder 54 is hinged with a scissors 55, the side wall of the L support plate 53 is fixedly connected to a guide rod 56, the surface of the guide rod 56 is slidably connected to an L support frame 57, the front of the L support frame 57 is rotatably connected to an extrusion roller 58 through a bearing, the surface of the guide rod 56 is provided with a support spring 2 59, and the end of the support spring 2 59 is attached to the surface of the L support frame 57.

[0052] By adopting such a solution, the workpiece surface is preheated by the preheating component 45. When the tape is later wrapped around the workpiece surface, the adhesive of the tape can be heated to soften it, thereby enhancing the fluidity of the tape adhesive and making it easier to penetrate into the microscopic pores on the workpiece surface, forming a mechanical anchor and improving adhesion.

[0053] When the workpiece is wound with tape, the movable cylinder 52 on the top of the connecting plate 51 is driven to move the L support plate 53, the limit cylinder 54 and the scissors 55. When the workpiece is wound with tape, the movable cylinder 52 on the top of the connecting plate 51 is driven to move the L support plate 53, the limit cylinder 54 and the scissors 55. When the workpiece is wound with tape, the movable cylinder 52 on the top of the connecting plate 51 is driven to move the L support plate 53, the limit cylinder 54 and the scissors 55. The support plate 53 and the limiting cylinder 54 are displaced synchronously to extend the L-support plate 53 out of the fixing frame 2, thereby aligning the scissors 55 hinged to the limiting cylinder 54 with the mounting rod 311. During the alignment of the scissors 55 with the mounting rod 311, the piston rod of the limiting cylinder 54 is extended outward to open the blade ends of the scissors 55 in advance, so that the blade ends of the expanded scissors 55 are located on the left and right sides of the tape. Then, the piston rod of the limiting cylinder 54 is retracted inward to drive the blade ends of the scissors 55 to close and cut the tape.

[0054] At the same time, when the L support plate 53 moves outward, the L support frame 57 and the squeezing roller 58 on the surface of the guide rod 56 will move synchronously. The squeezing roller 58 will support the end of the cut tape to hang down. When the winding wheel 31 drives the connecting plate 51 to rotate again, the squeezing roller 58 can wrap the hanging tape around the outer wall of the workpiece.

[0055] In addition, when the moving cylinder 52 is not driven, the end of the squeezing roller 58 is aligned with the end of the mounting rod 311, so that after the tape roll installed above the mounting rod 311 is wrapped around the surface of the workpiece, the workpiece packaging tape can be pressed in time by the squeezing roller 58 to avoid the problem of bubbles easily occurring due to the loose adhesion of the workpiece packaging tape. By setting the support spring 2 59, the telescopic height of the L support frame 57 can be adjusted, and the squeezing roller 58 can be adjusted to adjust the fit according to different workpiece sizes by adjusting the telescopic height of the L support frame 57.

[0056] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
