Description

Technical Field

[0001] The utility model relates to the technical field of ultraviolet light curing hose production, in particular to a special film coating device for ultraviolet light curing hose. Background Art

[0002] UV-curing hose is a hose that uses UV-curing technology to cure coatings or glue in a very short time. After the UV-curing hose is manufactured, a layer of spray liquid needs to be sprayed on the outside to increase the service life of the hose.

[0003] The existing UV curing hose is sleeved on the outside of the rotating shaft, and the rotating shaft is rotated to rotate the hose, so that the spray head arranged on the top of the rotating shaft can evenly spray the hose. However, the existing ones still have the following shortcomings:

[0004] 1. In actual operation, the diameter of the hose varies, while the size of the rotating shaft is fixed and cannot be adjusted according to the size of the hose. When the size of the hose is larger than the rotating shaft, the hose and the rotating shaft cannot be completely fixed. Therefore, when the rotating shaft rotates, the hose cannot rotate with it, making it impossible for the sprinkler head to spray the hose in all directions, resulting in uneven film formation. Due to the lack of film liquid in some areas, the film has a poor protective effect on the hose, which reduces the service life of the hose;

[0005] 2. When the existing device is laminating, the laminating head has a certain spraying range, but the length of the hose is different. When the hose length is greater than the spraying range of the spray head, a complete laminating film cannot be formed on the outside of the hose, so that some areas cannot be protected by the laminating film, thereby reducing the service life of the hose. When the hose length is less than the spraying range of the spray head, part of the spray liquid directly falls to the bottom of the device, resulting in a waste of spray liquid;

[0006] 3. During use, due to the effect of gravity, excess spray liquid will slide to the bottom of the hose and then drip. On the one hand, there is unevenness in the sliding process of the spray liquid, which makes the surface of the spray liquid uneven and affects the molding quality of the coating. On the other hand, excess spray liquid drips to the bottom, which will cause a waste of spray liquid, and long-term accumulation will affect the spraying of subsequent hoses. Utility Model Content

[0007] In order to solve the above problems, the purpose of the utility model is to provide a special coating device for ultraviolet light curing hose, which can adaptively adjust the size of the spray port according to the length of the hose.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A coating device for ultraviolet curing hose, comprising an installation box, a spray assembly installed on the top of the box, a limit assembly arranged parallel to the bottom of the spray assembly and rotatably connected to the installation box on one side, and a collecting assembly installed at the bottom of the installation box; the spray assembly comprises a material storage box fixed on the top of the installation box, a spray square pipe fixed on the bottom side of the top wall of the installation box, a plurality of communication channels penetrating and fixed inside the top wall of the installation box for connecting the material storage box and the spray square pipe, and baffles symmetrically arranged on both sides of the bottom wall of the spray square pipe. Liquid sub-assembly; a square spray port is provided at the bottom of the spray square tube, and slide grooves are symmetrically provided on the side walls on both sides of the spray port; the liquid blocking sub-assembly includes a first baffle plate slidably connected to the slide groove, an electric push rod fixed on the outer side wall of the spray square tube and a second baffle plate rotatably connected to the side wall of the spray port; the driving end of the electric push rod passes through the side wall of the spray square tube and is fixedly connected to the first baffle plate; the bottom of the second baffle plate at one end away from the side wall of the spray port is against the upper surface of the first baffle plate; the widths of the slide groove, the first baffle plate and the second baffle plate are the same.

[0010] More preferably, the limit assembly includes a rotating shaft rotatably connected to the inner wall of one side of the installation box and a plurality of limit sub-assemblies sleeved on the outside of the rotating shaft; the limit sub-assembly includes a ring sleeved on the outside of the rotating shaft, an adjusting sub-assembly evenly wrapped around the outer wall of the ring and fixed to the ring, and a limit plate fixed to the top of the adjusting sub-assembly.

[0011] More preferably, a plurality of elastic protrusions are fixedly provided circumferentially inside the collar, and a plurality of groove groups are evenly distributed along the axial direction on the outer wall of the rotating shaft, each of the groove groups is composed of a plurality of grooves that are matched one by one with the elastic protrusions, and the number of the groove groups is greater than the number of the limiting sub-assemblies.

[0012] More preferably, the adjustment subassembly includes a spring telescopic rod fixed to the bottom of the limit plate, an inner sleeve sleeved on the outside of the spring telescopic rod and rotatably connected to the limit plate at the top, and an outer sleeve fixed to the outside of the ring; the inner sleeve is threadedly connected to the outer sleeve.

[0013] More preferably, the collecting assembly comprises a scraper rotatably connected to the side wall of the mounting box and a collecting box slidably connected to the bottom of the mounting box; guide plates arranged along the axial direction of the rotating shaft are symmetrically fixed on both sides of the top of the collecting box; the two guide plates are inclined toward each other.

[0014] The utility model has the following beneficial effects:

[0015] 1. Through the cooperation of the first baffle, the electric push rod and the second baffle, the spray port can be shielded, thereby reducing the spray area of ​​the spray port, so as to realize adaptive adjustment of the spray range according to the length of the hose, which can avoid that when the length of the hose is greater than the spray range, a complete coating cannot be formed on the outer wall of the hose, and the hose cannot be fully protected, thereby reducing the service life of the hose, and when the length of the hose is less than the spray range, part of the spray liquid falls to the bottom of the installation box without acting on the hose, resulting in waste;

[0016] 2. The utility model can adaptively adjust the height of the adjusting subassembly according to the diameter of the hose by setting the adjusting subassembly, so that the limit plate is in close contact with the inner wall of the hose, thereby fixing the hose to avoid mutual sliding between the limit assembly and the hose when the size of the hose is larger than the diameter of the limit assembly, so that when the rotating shaft rotates, the hose cannot rotate accordingly, resulting in the sprinkler head being unable to spray the hose in all directions, causing uneven film forming, and the lack of film liquid in some areas, which makes the film poor in protecting the hose, reducing the service life of the hose;

[0017] 3. The utility model can scrape off the excess spray material on the outer wall of the hose through the setting of the scraper, and at the same time scrape off the sliding marks of the excess spray material, and the excess spray material will flow along the guide plate to the collection box for collection, avoiding the waste of spray liquid and also avoiding the long-term deposition of the spray liquid at the bottom of the installation box to affect the subsequent hose spraying.

[0028] Through the cooperation of the first baffle 241, the electric push rod 243 and the second baffle 242, the spray port 221 can be blocked, thereby reducing the spray area of ​​the spray port 221, so as to achieve adaptive adjustment of the spray range according to the length of the hose. This can avoid the situation where a complete coating cannot be formed on the outer wall of the hose when the hose length is greater than the spray range, and the hose cannot be fully protected, thereby reducing the service life of the hose. It can also avoid the situation where when the hose length is less than the spray range, part of the spray liquid falls to the bottom of the installation box 1 without acting on the hose, resulting in waste.

[0032] As a possible implementation mode of the present scheme, preferably, the collecting assembly 4 includes a scraper 41 rotatably connected to the side wall of the mounting box 1 and a collecting box 42 slidably connected to the bottom of the mounting box 1; guide plates 43 arranged along the axial direction of the rotating shaft 31 are symmetrically fixed on both sides of the top of the collecting box 42; the two guide plates 43 are inclined toward each other; in the present device, the bottom of the scraper 41 is against the hose, and the scraper 41 can be used to scrape off the excess spray material on the outer wall of the hose, and at the same time, the sliding marks of the excess spray material can be scraped off, and the excess spray material will flow along the guide plate 43 to the collecting box 42 for collection, so as to avoid the waste of spray liquid and the influence of the spray liquid on the subsequent hose spraying due to the long-term deposition of the spray liquid at the bottom of the mounting box 1.

[0033] The working principle of this device is:

[0034] When coating the hose, first adjust the distance between the plurality of limit assemblies 3 according to the length of the hose, push the first baffle 241 toward the side close to each other by two electric push rods 243, so that the length of the spray port 221 is the same as the length of the hose, and then put the hose on the outside of the plurality of limit assemblies 3, and then adjust the adjustment subassembly 322 according to the diameter of the hose, so that the limit plate 323 is against the inner wall of the hose, and drive the scraper 41 by the motor so that the bottom of the hose is against the scraper 41, and drive the motor to control the rotation of the rotating shaft 31, and at this time, the spray liquid sprays the outer wall of the hose through the spray port 221.
