Description

Technical Field

[0001] This utility model belongs to the field of flexible core tube processing technology, specifically relating to a spraying processing equipment for seamless flexible core tubes. Background Technology

[0002] Seamless flexible core tubes are components used to roll various strip-shaped products such as solar films, tapes, or paper to facilitate product storage and transportation. In the processing of seamless flexible core tubes, spraying is a key process. Traditional processing equipment often has many problems. On the one hand, it is difficult to apply a stable extrusion force to the core tube during processing, causing the core tube to be unable to stay in a fixed position. This makes the core tube prone to shaking and displacement during processing, which not only affects the accuracy of the processing action in the predetermined position, but also greatly increases the processing error. On the other hand, due to the unstable position of the core tube during spraying, uneven coating thickness or missed spraying often occurs. This not only affects the appearance of the product, but also reduces the protective performance and functionality of the coating.

[0003] To address the aforementioned issues, this application proposes a spray coating processing device for seamless elastic core tubes. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 As shown:

[0024] A spraying processing device for seamless elastic core tubes includes a spraying machine housing 1.

[0025] like Figure 1-Figure 5 As shown:

[0026] In conjunction with the above, in order to ensure that the core tube remains in a fixed position during processing and to prevent the core tube from shaking or shifting, a positioning assembly 2 is also included, which is symmetrically installed on both sides of the surface of the spraying machine housing 1. The positioning assembly 2 includes a positioning motor 21 screwed to the surface of the spraying machine housing 1, a bidirectional lead screw 22 fixed to the output end of the positioning motor 21, and moving plates 23 threaded to both sides of the surface of the bidirectional lead screw 22. The bidirectional lead screw 22 is rotatably connected to the inside of the spraying machine housing 1, and positioning rollers 26 are symmetrically arranged on opposite sides of the two sets of moving plates 23.

[0027] In this implementation scheme: when the core tube is pushed between the two sets of positioning rollers 26, the positioning motor 21 is started, and the positioning motor 21 drives the bidirectional lead screw 22 to rotate inside the spraying machine box 1, thereby driving the two sets of moving plates 23 to move relative to each other, and driving the positioning rollers 26 to move synchronously. When the positioning rollers 26 contact the surface of the core tube, and when the two sets of positioning rollers 26 are in close contact with the surface of the core tube, the positioning motor 21 is turned off, so that the two sets of positioning rollers 26 can be kept in this position, thus achieving a stable squeezing force on the core tube at all times.

[0028] In an optional embodiment: a bottom end of positioning roller 26 is provided with a backing plate 25, a spring 24 is fixed between the backing plate 25 and the moving plate 23, and positioning roller 26 is rotatably connected to the surface of the backing plate 25. A sliding block 27 is rotatably connected to the top end of positioning roller 26, and the sliding block 27 is slidably connected to a groove opened inside the spraying machine housing 1. A guide frame 29 is welded to the side of the surface of the spraying machine housing 1 near positioning roller 26. Several sets of springs 210 are symmetrically fixed on the upper and lower sides inside the guide frame 29. A support frame 211 is symmetrically fixed on the opposite side of the two sets of springs 210. Positioning roller 212 is rotatably connected inside the support frame 211. Limiting blocks 213 are symmetrically fixed on both sides of the surface of the support frame 211, and a limiting groove adapted to the limiting block 213 is opened inside the guide frame 29. One end of two sets of bidirectional screws 22 passes through the interior of the spraying machine housing 1 and extends to the outside of the spraying machine housing 1, and is connected to a chain 28 through a sprocket.

[0029] In this implementation plan: when the seamless elastic core tube needs to be sprayed, firstly, align the end of the core tube with the middle of the gap between the two sets of positioning rollers 212, and then push the core tube into the gap between the two sets of positioning rollers 212. Through the insertion of the core tube, the two sets of positioning rollers 212 can be pushed to move in opposite directions, thereby driving the support frame 211 to move synchronously, thereby compressing the spring 210 to deform and generate elastic force. Through the elastic force of the spring 210, the positioning rollers 212 can be pressed tightly against the surface of the core tube, thereby achieving automatic positioning of the core tube. Through the action of the spring 24, the positioning roller 26 and the core tube can be buffered, which effectively reduces the instantaneous impact force of the positioning roller 26 on the core tube and avoids the core tube from being deformed or damaged due to excessive pressure.

[0030] It should be noted that both positioning roller 26 and positioning roller 212 have flexible materials bonded to their surfaces to prevent hard contact with the surface of the core tube.

[0031] Furthermore:

[0032] In conjunction with the above, in order to achieve uniform spraying of the surface of the core tube, a spraying assembly 3 is also included, which is installed inside the spraying machine housing 1. The spraying assembly 3 includes a spraying ring 31 fixed inside the spraying machine housing 1, an expanding motor 32 fixed on the surface of the spraying ring 31, and a drive gear 33 fixed on the output end of the expanding motor 32. The surface of the drive gear 33 is meshed with a transmission gear ring 34, and the transmission gear ring 34 is rotatably connected to the surface of the spraying ring 31. The surface of the spraying ring 31 is provided with a number of spraying heads 312 arranged in a ring array.

[0033] In this implementation scheme: as the core tube continues to be pushed, when the core tube is pushed to the position of the spraying ring 31, the expanding motor 32 is started to drive the drive gear 33 to drive the transmission gear ring 34 to rotate on the surface of the spraying ring 31, thereby driving multiple sets of spraying heads 312 to approach the surface of the core tube until they are at a set distance from the surface of the core tube, so as to achieve uniform spraying processing on the surface of the core tube.

[0034] In an optional embodiment: a driven gear 35 is meshed with the side of the transmission gear ring 34 near the spray head 312. A driven shaft 36 is fixed inside the driven gear 35, and the driven shaft 36 is rotatably connected to the surface of the spray ring 31 via a bracket. A bevel gear component 37 is fixed to one end of the driven shaft 36. A transmission shaft 38 is coaxially fixed inside the bevel gear of the bevel gear component 37. The transmission shaft 38 is rotatably connected to the surface of the spray ring 31 via a bracket. An expanding gear 39 is fixed to the surface of the transmission shaft 38. An expanding rack 310 is meshed with the surface of the expanding gear 39. A positioning frame 311 is fixed to the side of the spray ring 31 near the expanding rack 310, and the expanding rack 310 is slidably connected inside the positioning frame 311. The spray head 312 is fixed to one end of the expanding rack 310.

[0035] In this implementation scheme: by starting the expanding motor 32, the drive gear 33 is driven to rotate the transmission gear ring 34 on the surface of the spraying ring 31, which in turn drives multiple sets of driven gears 35 and driven shafts 36 to rotate on the surface of the spraying ring 31. The rotation of the driven shaft 36 drives the bevel gear 37 to rotate, which in turn drives the transmission shaft 38 to rotate on the surface of the spraying ring 31, which in turn drives the expanding gear 39 to rotate synchronously. As the expanding gear 39 rotates, the expanding rack 310 can slide inside the positioning frame 311, which in turn drives the spraying head 312 to move synchronously and move closer to the surface of the core tube.

[0036] The working principle and usage process of this utility model are as follows: When it is necessary to perform spray coating on a seamless elastic core tube, first align the end of the core tube with the middle of the gap between the two sets of positioning rollers 212, then push the core tube into the gap between the two sets of positioning rollers 212. Through the insertion of the core tube, the two sets of positioning rollers 212 are pushed to move in opposite directions, thereby driving the support frame 211 to move synchronously, thus compressing the spring 210 to deform and generate elastic force. Through the elastic force of the spring 210, the support frame 211 can be rotated to rotate. Positioning roller 212 is in close contact with the surface of the core tube, thereby achieving automatic positioning of the core tube. It can adapt to core tubes of different diameters, ensuring close contact with the core tube surface for positioning. This ensures that the core tube is accurately positioned in the equipment, avoiding processing errors caused by core tube position deviation. At the same time, the flexible contact of positioning roller 212 also reduces wear on the surface of the core tube, without leaving obvious indentations or scratches on the surface of the core tube, ensuring the appearance quality of the core tube and extending its service life.

[0037] Furthermore, as the core tube is pushed, when it reaches the space between the two sets of positioning rollers 26, the positioning motor 21 is activated. The positioning motor 21 drives the bidirectional lead screw 22 to rotate inside the spraying machine housing 1, thereby causing the two sets of moving plates 23 to move relative to each other. A spring 24 then moves the contact plate 25 towards the surface of the core tube, causing the positioning rollers 26 to move synchronously. When the positioning rollers 26 contact the surface of the core tube, the spring 24 provides cushioning between them, effectively reducing the instantaneous impact of the positioning rollers 26 on the core tube and preventing damage to the core tube due to... If the core tube is deformed or damaged due to excessive pressure, the positioning rollers 26 can be kept in this position by turning off the positioning motor 21 after the two sets of positioning rollers 26 are in close contact with the surface of the core tube. This ensures that the core tube is always in a fixed position during the processing, thereby preventing the core tube from shaking or shifting. It also ensures that the processing action is accurately applied to the predetermined position, reduces processing errors, and avoids processing interruptions or repeated adjustments due to unstable position. In the spraying operation, the fixed position of the core tube can ensure that the paint is evenly covered on the surface, and there will be no uneven coating thickness or missed spraying due to shaking.

[0038] As the core tube continues to be pushed, when it reaches the position of the spraying ring 31, the expanding motor 32 is activated to drive the drive gear 33, which in turn drives the transmission gear ring 34 to rotate on the surface of the spraying ring 31. This, in turn, drives multiple sets of driven gears 35 and driven shafts 36 to rotate on the surface of the spraying ring 31. The rotation of the driven shaft 36 then drives the bevel gear 37 to rotate, which in turn drives the transmission shaft 38 to rotate on the surface of the spraying ring 31. This, in turn, drives the expanding gear 39 to rotate synchronously. As the expanding gear 39 rotates, it drives... The expanding rack 310 slides inside the positioning frame 311, thereby driving the spray head 312 to move synchronously and approach the surface of the core tube until it is at a set distance from the surface of the core tube, so as to achieve uniform spraying of the surface of the core tube. This ensures that the paint can accurately cover the surface of the core tube, ensuring that the coating thickness on the surface of the core tube is consistent and avoiding local over-thickness or under-thickness. Moreover, it can achieve uniform spraying according to the specific specifications of the core tube, so that the spraying equipment can adapt to diverse production needs and improve the versatility of the equipment.

[0039] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
